However, this display isn't built for today's technology. Instead, it's a concept screen designed to showcase TCL CSOT's capabilities, especially as Nvidia is rumored to launch the next-generation RTX 5000 series graphics cards this year.

So you mean to say Nvidia's upcoming RTX 5000 series GPUs are gonna support such high refresh rate tech from the get-go ? That's why TCL is showcasing their display ?

LOL, not gonna happen, since this has nothing to do with Nvidia's announcement.

Beyond ~240hz, the only reason for this is the latency of display of the frames you have generated. Very few games are going to produce content that fast, even on next gen hardware. But there is a real advantage to getting the next frame onto the screen, and top gamers will continue to find advantage for this out to at least 2khz.

I can see uses in animal studies: https://asknature.org/strategy/eyes-see-300-images-per-second/
With a flicker-fusion frequency six times faster than ours, dragonflies see 300 images per second, so they would see a movie for what it truly is – a slide show made up of a sequence of static images.”
and more generally: https://en.wikipedia.org/wiki/Flicker_fusion_threshold#Non-human_species

And while there are ways to sync frame rate refreshes between monitors and a video camera, this may help with flicker in movies and other video recordings.

I did some maths...
3840x2160, 8bit, 1000Hz = 248.83Gbps
HDMI 2.1 cable maxes out a 42.8Gbps
You'd need six of them to drive that much bandwidth.

DP 2.1 cable maxes out at 80Gbps
You'd still need 4.
Yes, I was thinking the author of this article missed this point. All the examples about low resolution at high refresh rate is not because the monitor, but actually due to limited cable bandwidth.

Capitalism product cycle.. the technogy already exist, but it "must be" launched in increments year after year so people believe there's a reason to keep buying forever

I think the way it actually works is that the company needs a product today in order to generate cash flow to stay in business, so they push what they can get working out and continue working on implementing advances for next year.

Could we have had 1000 Hz monitors 10 years ago? Maybe, but who could have afforded them then?

27'1440p/60fps is good enough, heck even a 24'1080p is good enough; 3440p/240fps is definitely luxury. More than this the only thing that makes sense to me would be two 40inch 4K 1000hz screens into a single super ultra wide ultimate experience or maybe a VR 1000Hz google with the same ppi of the 4K screens. I mean if you want raise the bat do it right!

Technology is hard and products tend to come iteratively after much research and development. How many times do we hear of cool tech in a research lab at a university only to wait 10+ years for someone to figure out how to make it cheaply enough for average people to use?

The bit rate for 4K @1000Hz @8Bit @4:4:4 with progressive frame scan is 197.75Gbps. With interlaced is 98.88Gbps. The upcoming Thunderbolt 5 can do 120gbps for display output purposes. So you need 1 or 2 TB5 cables.

Yeah, there is also chroma sub sampling, and using 6-bit+FRC to further reduce bandwidth requirements.
