Issues with Linus's recent videos

[xkronusx]

Without a doubt the title has pulled enough attention for you to click on this link.

 

This is going to be a long one, I've got plenty to say and time to write.

 

So here goes.

 

Apparently to get anyone's attention all you have to do is be negative, apparently it is enough to get someone to fly from Vancouver to NYC. So I am going to try and be constructively negative (not because I want them to come see me but rather get them to do some interesting investigative content, their investigative content is by far the best and the reason I enjoy their videos so much). Lately the content linus tech has pushed out (mostly from the main channel, you get what you get with the other ones) has been awful and I'm not talking about everything I am talking about specific videos. The video on the 13 inch laptop really struck a nerve with me because it was seriously biased just on the case scenario that linus prefers smaller laptops. I for one have come across plenty of people that can't use the 13" form factor just from a keyboard standard, it's basically why those little netbooks died even though their price point was good for the basic "lets do spreadsheets". Ignoring of course the horrible performance of the atom processor even under linux (I've used these things for anything from pfsense - windows 7 basic and oh heck was it ever basic).

 

Aside from that video we have the Luke video where he talks about how not many people are ready for VR. This video was done in the mindset to open up discussion but without any real direction, it comes across as a smug attitude (which is quite possible I've read into far too much) that derives from how much he wants it to succeed. Being so harsh on the subject will most certainly push away the fair weather customers of VR but the video in itself was just 7 minutes of you can't do this. I'd suggest that there will be no issue with the adoption of VR, there are porn websites that are already on the VR train. Wouldn't you know it porn pushes new tech, it's proven time and time again. Be cautious sure, but unbiased, put up content that is truly interesting or at least sticks to what you guys are good at, being here is the question, here is out proof and here is how we made it so much more interesting.

 

Alright so the negative junk is basically out of the way, hopefully I have prefaced this in a way that will open a constructive dialog.

 

Here is where I hope they (as a company) really pay attention to, it's coming from a mistake I have made myself and a topic LinusTech has recently delved into. Ok long story short I purchased a cable from monoprice called the

 

" Select Series Standard HDMI® Cable, 15ft Black ".

 

I was under the impression that any standard cable in 2016 was capable of pushing 2160P60 or at the very least 2160P30 (HDMI 2.0 vs HDMI 1.4, considering according to wikipedia HDMI 1.4b was released October 11, 2011) to my unfortunate surprise (and my lack of decent research on the very page I purchased it from) it only allowed my 8750M and my Radeon 6950 direct CU II 2GB graphics cards to use a maximum resolution of 1920x1080 60Hz.

 

Apparently I was supposed to purchase this

 

" Cabernet Ultra CL2 Active High Speed HDMI® Cable, 30ft ".

 

( I am posting the titles because I am unsure of posting direct links to buying items in the general discussions page, you can look both up on monoprice a website I happily found through LinusTech)

 

Ok so this cable has a small chip inside of it that pushes a higher rate os speed so that you can actually achieve 2160P ACCORDING TO THE SITE

"Supports more High Speed HDMI features, including 4K@60Hz, to greater distances with superior performance over passive High Speed HDMI Cables (18Gbps vs 10.2Gbps)".

 

Alright so my question is -- is it snake oil? Recently they did a video with the $1000 cable, my problem is my vessel subscription ended and hell if I would pay vessel for their sub adequate platform, unfortunately in Canada we do not have YoutubeRed because I would gladly put down the $10 a month on that, it would get used more than Netflix. So because my vessel account will not allow me to watch the video I watched a few days ago (due to the 7 day lock) I can not research this topic more for this comment.

 

 

Here is where everything gets wrapped up, I would seriously enjoy a video researching what cable is truly required to run 2160P60, I have a new TV so I understand I am in the minority here but this channel is all about new and exciting tech.

 

Find out can we run a 7 series AMD card from an HDMI and push 2160 at any resolution?  

Can you run a DisplayPort to HDMI to push 2160P

Are the HDMI cables with "(Cabernet ultra cl2 IC chip)" or "chips" in general) snake oil? 

Can you use DVI -> HDMI to push 2160P at all?

 

I really hope this post gains a ton of traction because there is so much Monster level false advertising (the worst being this $1000 cable) that it has become impossible to separate the junk from the real deal. I've been using DVI for my monitors for the last 5 years or so and this is the first time I have had a screen with only HDMI as an option.

But seriously have you never thought that you could use the heat form your pc? I sure have. And I found that the Pizza video was very funny. 

LTT has also been very busy with the new scrapyard wars and multiple staff being sick therefore a bit lack of content, temporarily. Also the hate on ''how to install a GPU'' this is were my faith for LTT fanbase dropped. How come people doesn't understand that new pc builders won't know how to build a pc if they've never done it before? The video covered  a more in depth take on it with even showing how to remove it. I thought it was good just like the rest of LTT and seriously if you don't like it then don't watch it. (no offense meant to you, just generally taking out my anger against ignorant viewers).

i do think that the "how to basic videos" were a great addition though, at least its tech related, and beginner friendly

people are hatin on it just because linus have been doing all those crazy stuffs lately that doing something basic is boring to his usual audience lol

[PooPipeBoy]

It doesn't matter if it's $10 or $1000, a HDMI cable is just a bloody HDMI cable.

[AshleyAshes]

Sometimes it's not the cable.  My Radeon HD 6950 couldn't do more than 1080p on HDMI, using a crappy no-name HDMI 1.4a cable, but my Radeon HD 7950 had no problem doing 2560x1440 at even 72hz on the same HDMI 1.4a cable.  This had nothing to do with 'Magic Cables'.

[GeekJump]

I think they should just make a Complaining thread for all the -what seems to be- hundreds of similar posts about "LTT content recently". That way we can all avoid that thread AND if they try to post it to general discussion or off topic, it will be deleted/moved

I'm glad to see I am not the only one who noticed the shift, and far be it from me to judge. My post is a suggestion of content because the content of the last while has been really lack luster. 

 

On the one hand you have amazing videos like 7 gamers 1 CPU, something I have been dying to figure out since I learned about multiseat computing. Then you have, lets warm a piece of pizza with thousands of dollars of computer hardware.

 

Don't get me wrong, it was mildly amusing but honestly this isn't even on the radar of what makes LinusTech good. The how you install a graphics card is right in their wheelhouse though. It goes along with the how to build a computer series, something I've shared with plenty of people for their first time builds.

I know how this forum seems to work, anything with drama attached to it gets the spotlight whether or not the subject is worth while.

Here's the thing, I'm not saying I can do it better. I'm barely suggesting what they should do and should not do. But the pizza video is just one of many examples of really sub par tech content, barely even relating to tech. If I take something electronic that produces heat and direct it towards pizza is that a tech video? Another video came to mind writing this. There was a video with Brandon talking about camera stuff under $100 and the video didn't have a bad premise but the finished content was lacking. Here we have a video discussing camera products but only one item had anything to really do with cameras, a camera lens. Realistic expectations makes good content, saying it's camera content and then showing off items that can be used with cameras but are not sold as camera equipment should have been more of discussion video. Instead of things under $50, it should have been called something along the lines of "what's in Brandons camera bag". Another staple of LinusTechs past videos.

Agreed, the how to GPU content is great for beginners and is only receiving hate because the hardcore guys can't related. Objectively speaking it was good content that anyone could watch and enjoy, unfortunately it seems like the community forgets LinusTech is trying to make content that everyone will watch, not just a small percentage of people.

k. tldr didn't read. you can't do it better.

An HDMI cable is an HDMI cable. The standard in both ends is what matters. 

Give me some legitimate proof that any standard cable can achieve 2160P because I have not been able to achieve it with my 8750M which should have the capacity to at least show the resolution 2160P30.

 

TL;DR: People take written information as gospel, LinusTech has proven time and time again that you should do investigative work to see if that is the case. What cable is needed to show 2160P when the output side has to be HDMI? What can be used?

 

Spoiler

Sometimes it's not the cable.  My Radeon HD 6950 couldn't do more than 1080p on HDMI, using a crappy no-name HDMI 1.4a cable, but my Radeon HD 7950 had no problem doing 2560x1440 at even 72hz on the same HDMI 1.4a cable.  This had nothing to do with 'Magic Cables'. 

That's what I found in my testing unfortunately, but I have read on forums like overclocker.net that you can get 2160P out of a 6 series card using some software tools and changing EDID information.

 

But here is my problem, I have a "7 series card", my 8750M (laptop deticated GPU) is technically a rebrand of the 7 series. Yet no matter the HDMI cable I can not get a higher than 1920x1080 maximum resolution.

What is considered "General discussion" or "Off topic" then? Do you have anything to contribute? Or are you just going to troll for attention. You didn't have to comment here, or even read this post for that matter. So you can kindly leave and stay away from this thread or add some actual constructive thoughts.

 

There is plenty of other topics on this forum to go and read.

[AshleyAshes]

Look, I dunno what to tell you.  What 'magical' properties do you expect the cables to have?  They are wires, they're just a series of wires tied together that link two different devices.  Nothing 'magical' in the cable will change how the two devices work.  Any trouble you have is with one device or the other. All that bullshit on the cable is just that, bullshit.  There are two kinds of HDMI Cable, Type A with 19 pins and the currently unused on ANY device, Type B connector with 29 pins which is larger and basically doesn't exist.  That's it, 19 pins and 19 copper wires going from one end to the other.  There is nothing MAGICAL or technical that can be added tot he cable to give it additional features or capabilities.  It's the devices on either end.  Any belief that the cable is causing this is tantamount to believing in ghosts, UFOs' or that black helicopters are following you on your commute.  It's bullshit and you're trying to assign blame for one problem, a problem with one device, probably in the firmware or it's overall design to be on the shoulders of some stupid copper cable.

 

This entire thread is stupid and demonstrates blatant ignorance as to what an HDMI cable even does.

This could be done in a 30 second video. With half of that being the outro.

"HDMI cables differ only in wire gauge and shielding. If you're not getting the right resolution or frame rate, then it's probably your GPU or display. If you liked this video, give us a thumbs-up, and if you disliked it, then you know what to do. Now that you're done watching this..."

You know you say something really ignorant and with no proof as if I am just supposed to accept that as gospel truth. But here is where you are undeniably wrong and I will give you an example. Networking cables generally all look the same since about Cat4 Ethernet, yet they all perform to different standards. The best part is their is no magic behind the cable, it is mostly to due with shielding. Yet! There is a difference! You can no achieve certain speeds with Cat4 vs a Cat6A STP cable. There is tangible proven evidence that there is a performance difference between the two.

 

So tell me, do you have any numbers? Any real proof? Have you even tried running 2160P with an HDMI cable? Why are you even commenting if you have not?

GREAT! Do a 30 second video! But you forgot something very important. They did a video about one $1000 HDMI cable! This is a topic they have talked about before! Why in this context is it unreasonable to look into, but in the context of the $1000 cable it was totally justified? 

 

So we know buying an $1000 cable is snake oil, but what about the $20 cable? The cable with the chip in it?

 

OH AND THE MOST IMPORTANT PART YOU ALL SEEM TO BE FORGETTING (caps lock for all those who seem to not read unless it is bold and capitalized) I AM ASKING FOR HOW TO DISPLAY 4K WITH AN HDMI! A DVI! AND A DVI -> HDMI OR DP -> HDMI!

 

There is a legitimate argument to be made because the standard for HDMI is all over the place. 

 

According to Wikipedia: 

 

HDMI 1.0 1920x1200P/60Hz

HDMI 1.1 1920x1200P/60Hz

HDMI 1.2 1920x1200P/60Hz

HDMI 1.3 2560x1600P/60Hz

HDMI 1.4 4096x2160p/24Hz

           3D 1920x1080P/24Hz

HDMI 2.0 4096x2160P/60Hz

          3D 1920x1080P/60Hz

          3D 4096x2160P/24Hz

 

https://en.wikipedia.org/wiki/HDMI#Versions

 

There is even a difference between the maximum bandwidth, this is not a basic "What cable is usable?"  this is a full blown discussion about what is actually necessary for 2160P. Hell none of the AMD cards to date have HDMI 2.0! 

 

Anyone reading this really needs to look at the bigger picture, all I am asking is for an in-depth look at what is necessary for 2160P in 2016. As far as I am concerned this falls under the same category of "how to".

[AshleyAshes]

You have fun spending thousands of dollars on cable trying to fix an issue with your graphics card then.   there are no classes of HDMI cables, there are device and displays that form to standards but all use the same cable protocol.  There is no such thing as a '1.3a cable' or 'HDMI 2.0' cable.  They all do it, all use the same 19 pins.  Even the ones that do 'ETHERNET OVER HDMI!' use the same cables.  Pin 19 is just of no use on HDMI devices lower than 1.4a, where as 1.4a added usage to the 19th pin.

 

The real issue is with your graphics card is your TMDS clock signal generator.  See, HDMI started as being basically an implementation of DVI with added audio and encryption support, most graphics cards that started offering HDMI just hung it off as a DVI port.  Even later ones were using the same TMDS clockgens, which is why you could say have a card with two DVI ports and one HDMI port, but since the card only had two clockgens it could only drive two single link connections, two DVI, one DVI and one HDMI, or a single DVI-Dual Link connection. (A lot of GPUs have four clockgens now) The thing is, HDMI outgrew that.  HDMI as a standard is now capable of signals well exceeding that of DVI and do it all on a single link instead of needing a pair of links to do the same job. This is why some GPUs HDMI ports, even if they are 'HDMi 1.4a' ports, are actually limited to an output below the limitations of the 1.4a spec. This is why my HD 6950 can't do 1440 over HDI where as my HD 7950 can do 1440p over HDMI.  You're hitting the same issue with 4K.  That's all it is.  No expenditure on cables will solve this because you have a hardware limitation that you want to believe you can defeat with a cable.  ...It's not going to happen.  But like I said, you don't even understand the root of your issue and you want to believe in magic cables.

I am trying to be as practical as it gets, I never said I was spending thousands of dollars haha. If anything the reason I am on this path is because my $5 USD 15FT HDMI cable could not push 2160P.

 

I have not bought another cable, nor am I looking to add more cost to my 2160P venture until Pascal and Polaris have dropped. My plan is to get everything as I need it. If my HDMI cable is the right specification then great!

 

But you mention some things that don't sit well with me, see here is a picture of my graphics card.

 

 

I pulled that from online, but it's what my card looks like. The ASUS Radeon HD 6950 2GB Direct  CU II.

 

There is no HDMI port, those are all display port, and the way I am pulling HDMI is from the DUAL LINK DVI port shown on the right. You don't seem to even consider what my root issue is because you believe I am some new tech enthusiast for asking questions about HDMI.

 

I never made any sweeping statement one way or the other, I asked questions and I am responded to with a holier that thou attitude about my concern.

 

Finally we get to the other issue, you say 6950 and 7950 are incapable of pushing 2160P which is fine. 

 

But! My device has a Radeon 8750M which would have come after the 7 series cards, even if it was a rebrand. It only has one HDMI port. Do you mind explaining why it can not push 2160P? Also why this is still not a good topic of discussion for a video?

I'm sorry, but the way you put 'DUAL LINK DVI' in all caps, do you somehow believe that putting a DVI to HDMI adaptor on a DVI-DL port would somehow give you potentially better output or that for some other reason, hooking up a DVI to HDMI passive adaptor to a DVI-DL port is inherently signifigant?

You do realize that dual link DVI pushes higher resolution right? I mean at this point not only are you cherry picking information and avoiding any questions but you are just being blatantly ignorant for arguments sake. 

 

Besides all that you seem to skip over the fact I have an 8750M with HDMI. My purposed question is still what does it take to get 2160P over HDMI and what options do you have in terms of flexibility.

 

 

Don't bother replying, you are of no help, you are the very reason the tech world gets a bad name. You don't want to educate or assist anyone, you would rather look down and pretend as though someone else is inferior for not knowing something you do.

No, I figured that this was exactly where you were going.  But there is no such thing as a dual link HDMI connection.  (There is actually an on-paper HDMI B connector that does dual links but it has never been produced in any product what so ever, it ONLY exists on paper in a standard thus far, the connector is much larger than HDMI A connectors)  Newer HDMI revisions achieve resolution than DVI by using a higher frequency signal rather than doubling up two signals.  Since you are using a passive adaptor, what you are using is just a pin out adaptor, it can't some how magically take a DVI-DL signal and somehow convert two links worth of DVI signal into a high resolution single link HDMI signal.

 

Again, you are demonstrating extremely poor understanding of the signals at hand in your quest for a cable that will overcome a short coming in your graphics chip.  I've already explained to you that a TDMS limitation in your graphics card is the cause of your problem, your only solution is to use a different graphics card.  That will be your ONLY solution.  ...or an ACTIVE Display Port to HDMI adaptor that is specifically capable of those resolutions.  DisplayPort has no TDMS signal of it's own (There as passive adaptors that just reroute the graphics card's TDMS signal that would otherwise be used on DVI or HDMI but then it's passing through non DP information) so you'd need to ensure that the Active DP adaptor you used was capable of more than 1080p.  For cost reasons, a lot of active DP to HDMI adaptors are only capable of generating a 1080p HDMI signal.

[Okjoek]

Feel the Bern.

[NeoFrux]

Did you forget the part where the $1000 HDMI cable didn't do anything differently than the cheapest possible HDMI cable they could find?

HDMI "versions" are all about signalling. If the cable's not shielded well enough, then it's possible that it will fail. But there is NO negotiation on the cable's part for what is supported or not, that all happens between the device and the display. In the case of your Radeon 6950, it only supports HDMI 1.2. In the case of your 8750m, I believe that does 1.3.

Your question regarding dual-link DVI is irrelevant; Dual-link DVI can support up to 2560x1600, and that isn't a resolution that is often exposed by displays connected via HDMI (despite being electrically compatible with DVI, devices, especially TV's, connected via HDMI ports often list different resolutions than those connected via DVI).

TL;DR, you're not getting 4K out of DVI no matter how hard you try, and you're not going to be able to output a resolution higher than the standard your device supports via HDMI, no matter how good the cable is. The TMDS transmitter on the device itself (on both ends) needs to be capable of the higher bandwidth. The cable is irrelevant.

But hey, feel free to buy a high-end "HDMI 2.0" cable and let us know how that works out for you.

No, I figured that this was exactly where you were going.  But there is no such thing as a dual link HDMI connection.  (There is actually an on-paper HDMI B connector that does dual links but it has never been produced in any product what so ever, it ONLY exists on paper in a standard thus far, the connector is much larger than HDMI A connectors)  Newer HDMI revisions achieve resolution than DVI by using a higher frequency signal rather than doubling up two signals.  Since you are using a passive adaptor, what you are using is just a pin out adaptor, it can't some how magically take a DVI-DL signal and somehow convert two links worth of DVI signal into a high resolution single link HDMI signal.

 

Again, you are demonstrating extremely poor understanding of the signals at hand in your quest for a cable that will overcome a short coming in your graphics chip.  I've already explained to you that a TDMS limitation in your graphics card is the cause of your problem, your only solution is to use a different graphics card.  That will be your ONLY solution.  ...or an ACTIVE Display Port to HDMI adaptor that is specifically capable of those resolutions.  DisplayPort has no TDMS signal of it's own (There as passive adaptors that just reroute the graphics card's TDMS signal that would otherwise be used on DVI or HDMI but then it's passing through non DP information) so you'd need to ensure that the Active DP adaptor you used was capable of more than 1080p.  For cost reasons, a lot of active DP to HDMI adaptors are only capable of generating a 1080p HDMI signal.

Funny thing is you answered my question, after all that I finally have all the information I need to know. But if you call someone ignorant for not knowing at a time where they are asking questions you are failing to actually be helpful.

 

From what I gather simply put (and for others looking for this answer):

• HDMI cable does not matter
• DVI -> HDMI at this point in time will not achieve a 2160P resolution
• DP -> HDMI at this time is not cost efficient 
• HDMI cables with chips in them only upscale

Did you forget the part where the $1000 HDMI cable didn't do anything differently than the cheapest possible HDMI cable they could find?

HDMI "versions" are all about signalling. If the cable's not shielded well enough, then it's possible that it will fail. But there is NO negotiation on the cable's part for what is supported or not, that all happens between the device and the display. In the case of your Radeon 6950, it only supports HDMI 1.2. In the case of your 8750m, I believe that does 1.3.

Your question regarding dual-link DVI is irrelevant; Dual-link DVI can support up to 2560x1600, and that isn't a resolution that is often exposed by displays connected via HDMI (despite being electrically compatible with DVI, devices, especially TV's, connected via HDMI ports often list different resolutions than those connected via DVI).

TL;DR, you're not getting 4K out of DVI no matter how hard you try, and you're not going to be able to output a resolution higher than the standard your device supports via HDMI, no matter how good the cable is. The TMDS transmitter on the device itself (on both ends) needs to be capable of the higher bandwidth. The cable is irrelevant.

But hey, feel free to buy a high-end "HDMI 2.0" cable and let us know how that works out for you.

I'm guessing you missed the part where I couldn't watch the video again because my vessel subscription expired. I also mentioned I'm not going to pay for vessel because it's a junk platform that rarely worked properly for me. Either comments would not get posted or videos wouldn't load, or videos would load at the worst quality on a 120Mbps connection. I've got plenty of reasons why I wouldn't use their platform again, nor try and cheat the system by making another account.

 

When did I ever say I was dead set on purchasing the cable? I just wanted information on what makes those cables any different. It seems to me like you have all looked into this looking for some drama where there is none to be found. At the very end of this thread anyone looking for this answer will have a decent sum of knowledge at their disposal and can make an educated decision on what they need to run a 2160P setup.

 

Thank you all for your help, cheers.

If $13.99 USD is out of your budget, you might want to seriously reconsider 4K at all...

Haha always missing the big picture eh?

 

It might be $13.99 but once I use my Canadian Rupie then pay for border fees it won't just be a $14 item.

 

But hey lets forget about the 4k 42 inch screen I just bought that could be any amount of money. The budget of course is defined by the least important items first of course.

1) It's actually $12.99 for the white one from the same company on Amazon.ca.  Learn to shop before you moan and complain.  https://www.amazon.ca/CableCreation-DisplayPort-Adapter-Support-Converter/dp/B01912GND0/ref=sr_1_4?ie=UTF8&qid=1459030559&sr=8-4&keywords=DisplayPort+4K+HDMI

 

Wait, I found it in black too!  https://www.amazon.ca/CableCreation-DisplayPort-Adapter-Support-Converter/dp/B013G4EXMM/ref=sr_1_7?ie=UTF8&qid=1459030559&sr=8-7&keywords=DisplayPort+4K+HDMI

 

There, a dollar cheaper AND you have color options.

 

2) I'm just going to post this photo of the CN Tower from my living room and then ask that you explain to me that this 'Canadian Rupie' and 'Border Fees' that I am missing in 'The Big Picture'.
