4k Help!

[star-lord]

Please Help!

If you´re someone who owns the seiki 39" 4k tv could help me please

could you try to use two hdmi´s because I´ve seen something about it working as two sceens if you use two hdmi´s and it could run @60hz, then if you have an amd gpu use eyefinity to make them "one monitor" and voila you get 4k@60hz, the eyefinity is only

necesery for gaming,

If it works could you make a video about it or tell me.

 

 

 Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks!  Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks! Thanks!

 

my specs:

and before christmas  I´ll add two 290´s or 980´s or even 390`s,

Right now the intel hd4600 if good enough for plantet side 2 on lowest settings 720p at 60-70 fps(basicly console peasant level but the fps is higer)

The Seiki 4K's are 30Hz only when running at 4K.

 seiki 4k tvs are meant to be quite bad, pc perspective said the color reproduction was poor and that the 30Hz at 4k is a deal breaker(that was the 50inch one so i dunno it may have changed), you could use it for 1080p gaming it supports 120hz apparently.

aperantly you´re not nerdy although you say you are, I´m well aware that it´s 30hz@4k, but I want to know If I could use two hdmi cables as I said but apereantly you didn´t read what I wrote so next time read before answering thank you.

By 30Hz@4K only, I mean the panel itself can only run at 30Hz when displaying a picture at 4K resolution. I read what you wrote, and I'm just saying it's not possible, so read the reply properly.

 

Some monitors have panels that can run 60Hz@4K, but as HDMI 1.4 can't do 60Hz 4K with a single cable, it gives you an option to run two separate cables and combine them as one image to have 4K at 60Hz. Even if you could do this with the Seiki, it would make no difference as the panel itself can not run at 60Hz when displaying a 4K resolution image.

I watched Adams aka mr thaiboxes video and his only complaint was 30hz, I know it is 120hz@1080p, I only want to know if I could "hack" it into 4k@60hz. Like I said I´ve seen something about using two hdmi´s and the computer regonizes it as two 1920x2160 monitors at 60hz, then use eyefinity to make them one monitor,

but I´d be more than happy to see a video of it or something.

are you 100% sure that the panel it self can´t do more than 30hz, and I read your anser but it wasn´t the clearest answer since you didn´t explain why it´s only 30hz.

I doubt it, the image processing in the TV itself is probably too slow.

This is what I'd do. Apparently it's one of the few TVs that does support native 120Hz @ 1080p http://www.blurbusters.com/4k-tv-for-only-1500-supports-1080p-120hz-and-720p-192hz/

This isn't possible with the Seiki, as it doesn't have that function, and even if it did for some reason, the panel is most likely incapable. Even if higher end 4K TVs had 60Hz capable panels they would have this function, but many don't since most are 4K@30Hz only, with a few exceptions.

The TV itself is capable of 60Hz at 1080p (and even true 120Hz) so the panel is obviously capable of operating at 60Hz.  The reason it can't do 4K at that frequency is the limited bandwidth of HDMI.  He's asking if you can split the TV in basically a PbP mode where each half of the screen can be used as an individual display, one from each HDMI connection.  The computer would recognize it as two 1920x2160 monitors side by side and since it's half the resolution of 4K, each one could run at 60Hz, then you configure them in eyefinity and voila you have 60Hz 4K.  A sort of "HDMI teaming" workaround.  In fact this is exactly how most earlier 4K monitors operated like the ASUS PQ321Q (I think that was the model) or the Dell 24" 4K one.  Even though DisplayPort 1.2 had enough aggregate bandwidth, the timing controllers they were using couldn't actually handle that much data, so they had to combine multiple timing controllers working together (as in, set it up internally as two monitors daisy-chained together with a timing controller dedicated to each half, like they were separate monitors) and then combine them in software.  The computer still recognized them as two separate monitors side by side.

 

It's a clever idea, but not possible here.  The Seiki doesn't support picture-by-picture, so it can't use half the screen for one input and half the screen for another, unfortunately.  You can hope for a software update but I highly doubt it, I suspect the display controller would not be able to handle it, since the maximum designed load (so to speak) is 1920x1080 120Hz or 4K 30Hz, or in other words the full bandwidth of a single HDMI connection.  It probably would not be able to process the full bandwidth of two at a time, since generally TVs don't put in anything more powerful than they need to.  There would also not be much point from Seiki's standpoint, since I think Seiki would rather focus their efforts on getting a new model out the door with HDMI 2.0 which is a much smoother solution for 4K 60Hz.

Thank you, finaly someone who knows something, seiki has announced I belive 28", 32" or 36" and 40" 60hz 4k monitors, but I don´t know when they are released. Could it be possible to somehow "hack" it or download a 3rd party software to do this. Or as you said is the tv too weak, well I currently have a 1080p aoc wich is good enough for now.

I don't know of any hacks like that personally, you can look around but I doubt there is one out there.  And like I said the TV's processor is probably not meant to handle that much data, but that is just speculation on my part.

read Glenwings post he explained really good so you might learn something, this may sound mean but I mean it in a good way since he knows what he talks about

Ok, but I´ve seen a video of it being done but can´t find it anymore. It looked legit. 

[werto165]

@Glenwing So if there was a TV that could do 4k 60Hz(which im pretty sure there is) would it be the same bandwith as 1080p @240Hz and would that be even possible?

 

im basing this off, the Seiki example 1080p 120hz 4x resolution is 4k so = 120/4 = 30Hz or does it not work like that at all?

That's correct, although there are no displays that I'm aware of that will accept a 240Hz input because the display panel would not be capable of switching that fast, 144Hz is the most I've seen (laboratory tech still in development notwithstanding).  But in terms of required bandwidth, you're right, 4K 60Hz would be equivalent to 1080p 240Hz.

so monitors such as this one are gimmicks? http://www.overclockers.co.uk/showproduct.php?prodid=MO-004-EO

 EDIT: EIZO’s Turbo 240 converts 120 Hz input signals to 240 Hz so is this similar to the "600Hz" TV's

Yeah, it only takes a 120Hz input signal, doubles the frames and strobes the backlight.  It does actually improve things and reduce blur, so it's not a total gimmick, but not true 240Hz either.  600Hz TVs are a different topic, 600Hz TVs are usually plasma TVs, not LCDs, and Hz means something entirely different for that technology, since Hz is just a generic unit for cycles per second.  Just like a 3GHz CPU has nothing to do with a 120Hz LCD, neither does a 600Hz plasma, but people get it mixed up a lot.  That being said, companies know that people get mixed up, so they like to trumpet that number from the rooftops But strictly speaking, it's not a marketing gimmick or lie, just a difference in how the technologies operate if it is a plasma TV, which most 600Hz TVs are.  I do know what you are referring to though, and almost any TVs that are LCD (or anything LCD-based like so-called "LED" TVs) labeled 120Hz, 240Hz, 480Hz, or even a 600Hz LCD (uncommon) still only take 60fps from the source and aren't "true 120Hz", just interpolated frames and marketing fluff.  The Seiki models can do true 120Hz though, so they are a notable exception.

http://hardforum.com/showthread.php?t=1793829 the guy said that nvidia controllpanel reconizes it as 2 monitors if you use 2 hdmi´s

[star-lord]

so if I get an amd gpu and use eyefinity to combain the two "monitors" 

[Glenwing]

That's pretty typical, but the issue is you have to get the TV to display from both inputs at once, using half the screen for each. This is known as Picture-by-Picture mode, and it's not a feature of this TV as far as I'm aware. I have the 50" version so I did look into these kinds of things too when I was setting it up

well then this isn´t worth getting for a monitor, do you know any 39"-42" 4k tv that supports 4k@60hz  and is around 500$

I don't, sorry.  We can wait for Seiki's 40" monitors, which are supposed to come around end of 2014/early 2015, but we don't know how much it will cost yet.
