Viewsonic are advertising a 108" LED Display with a "Refresh Rate: up to 4440Hz". How is that possible? The specs do mention that the "Vertical Scan Rate: 56-85Hz". But when I'm looking up the definition of vertical scan rate, it's telling me that it is synonymous with refresh rate. So, what's with the discrepancy? Is it 4440Hz, or 56-85Hz?

Yes, you read that right. AMD lowest tier of graphics card announced at the recent event, costing only $579, beats Nvidia's top of the line RTX 3090 that costs at least $1499. Albeit, this is only in Battlefield V @ 1440p. However, this is just adds insult to Nvidia's injury, and it something I've never heard of happening ever before. (If you if any instance where that happened, please let me know).

I had a feeling for that. Kinda feel the same for tp-Link, honestly. Thank you for input, but I think I'll pass on this, even though it's like 30% on Amazon now. Probably for a good reason.

Yup. And for any advice, or instructions. Like when someone asks me for direction I keep doubting myself all day.

https://www.dlink.com/en/products/dir-x5460-exo-ax-ax5400-wi-fi-6-router Any experience with this? Plenty of Amazon reviews are complaining about range issues, so I'm not too sure. On paper it looks nice, but I'd appreciate someone with hands-on experience. Alternatively, what do you guys think about D-Link products?

There is a way to satisfy demand. Part of production and logistics is to predict the demand and preemptively ramp up production. AMD seems to be doing it, but let's see how that turns out.

You sure about that? AMD seems to be coming swinging at full-force.

Nvidia announced that they're expecting their RTX 3080/3090 shortage to last well into 2021, leaving their customer boiling at their seemingly cold response to the F5 mania, and the scalping debacle. Nvidia had a practically unprecedented demand and market potential that has be stacking up since 3-5 years ago, with people holding on until that golden leap in performance finally worthy of their aged savings. And what was Nvidia's attitude? "Well, honey. Guess you gotta keep an eye out and wait. Teehee ;)" In normal circumstances, that would've been fine. They practically have the monopoly on top performing graphics cards. People have no option but to patiently wait for papa Nvidia's gracefully bestowing them the honor of paying money to get their hands on those 30 series cards. Normally, that can be a good strategy. Normally, this is a top market psychology play; you're supposed to milk their attention for maximum loyalty, bravado and clout. Where Nvidia could have possibly messed up big time? AMD's new graphic cards. Nobody expects the Radeon inquisition. Should the rumors and speculations prove to be true, this could be Team Red's biggest win in the decade. The card doesn't even need to be better than the 3080. Even if the card was slightly less powerful than the 3080 but with the same price point, they'll sweep the market. The hungry masses can't hold it any longer. Hype-man already is partially Team Red with the new Zen 3 architecture, so getting a full red-set is kinda....appealing. Once people get over the non-green tint of the card, it's practically over. 3-5 years of build up is now locked into AMD. Team Green could easily have locked up the market and sank the Radeon Armada before it was christened. Once anyone had bought the 3080, there's no reason to even lend ear to the announcement. Even if Big Navi had %10 improvement over the 3080 with comparable price, you've already had bought a graphics card. Who would switch? Why would anyone switch? The door would have been closed for 1-2 years with Nvidia's name on the plaque. But Nvidia's lack of initiative and risk-taking may have already mortally wounded their market share. The choice of controlled, but slow production line usually is a good idea. If they had produced too many, with too little demand, then it would have disastrous to have all that extra stock that can lose 50% of it's value within a year. So it's not that they were stupid, but luck favors the brave. Now the ball is in Dr. Sue's field. She can drive the proverbial stake really, really deep if she had the foresight of this and went full throttle in production. The moves have already been made, and the course of action is practically been sealed. The next 30 days should be most exciting. What do you think? What are you speculations, and are there any wild bets you'd like to make? Does what I said make sense, or are they the rambling of an armchair fool? I'd like to hear more from you.

Thank you for you suggestions.

I've looking around to upgrade my router to something compatible with WiFi AX. The best thing I could find is this. However, it seems that only 1 5GHz band is AX, the other one is AC. Also, it seems that if this router is used for a mesh network, the AX is utilized as a back-haul, and the routers becomes an AC router. The issues seems to persist even if an Ethernet cable is used as a back haul. Does anyone have recommendation for a fully AX WiFi router? None of the "partially" AX business, please. Thank you!

BZ's is probably the video I have many issues with. One of those is the "how easy" just stabbing it with an oscilloscope and monitoring is. It's not that easy because it will take a very, very high sample rate oscilloscope with appropriate high-frequency probes. At 2 GHz clock speed, the rise time is in picoseconds, and so should be any dips. To be able to see the square wave somewhat reasonably, you'd need an oscilloscope that can sample the at least up to the 3rd harmonic of of the 2 GHz clock, in other words you need at least a 6 GHz oscilloscope, which costs around $15K. Even then, the blue trace is all what you'd get. You can see how much information is lost, and the rise time is very slow compared to the actual signal (in green). I'm not sure how many harmonics you need to achieve "acceptable" readings. To get something like the blue trace in the following graph, you need to sample at the 9th harmonic, so you'd need an 18 GHz, or more, oscilloscope. Would you to guess how much that class of an oscilloscope costs? Just a cool $175K. It's close to the kind of test equipment needed to analyze HDMI and other high-bandwidth signals. To be clear, the green line is not what you'd get when measuring across the capacitors, but it serves as the fundamental signal and frequency that will cause voltage dips that may, or may not, be causing the issue. Being able to sample the square wave will means you can reasonable sample the dips cause by it. This is all, of course with plenty of oversimplifications, but it should help to get the idea across. Is it simple to measure? Yes, if you have the equipment to play with. Then again, I've seen Youtubers play with fancier machines, so you never know how feasible it could be.

There was no begging or asking for any sort of donations, and nothing like that was advertised or linked. There wasn't any name for any project or page mentioned. There is even any funding page or project related to that subject, as far as I know. It was a question of "How interested is community in the subject. Is it interesting enough that they'd be willing to contribute financially to it"? Anyway, it's not important to the post, so whether it's removed it doesn't change the subject.

To proper investigation, it would take more expensive equipment than I have. Thank you for the suggestions, but in text it might be too technical and hard to understand. It'll be probably easier for everyone to just setup a record screen and demonstrate the performance with a couple of simulations. As per Dedayog's suggestion, I'll make a video that touches on the subject theoretically. Start simple, you know? I'll see if I'm allowed to post the video here in the forum, and if so we'll see how people react. If they're interested, I can continue from there, if it dies, it dies.

That's the problem. I'm not a Youtuber or anything, nor am I planning to be one. There's isn't really any incentive for me to make a video or a bigger project out of it. Many, if not most Kickstarters projects are media project where someone is making a video about a subject of interest. I've also seen similar posts to mine bearing fruit to something bigger. But all of that is secondary to my main point, which is discussion about the subject. Someone told me it was an open and shut case and that the community no longer cares about it. But I would like to hear from more people.

So, would just a theoretical video without any practical application be interesting enough for you to watch?
