TCL smashes the refresh rate barrier as it demonstrates a 4K 1000Hz panel

Gaming monitor technology continues to advance. When we see new models come to market with ever higher refresh rates, they're usually 1080p models. With the advent of OLED technology in particular, refresh rates are ticking upwards on higher resolution panels too. 

1000Hz, though? That's never been seen on any gaming panel. Screens capable of 540Hz are on the market, but they're still rare, and very expensive 1080p TN panels aimed at competitive gamers. 4K examples such as the stunning are capable of [[link]] 240Hz, but that's still well short of the 1000Hz 4K panel spotted by at the DisplayWeek 2024 conference in California.

Surprisingly, TCL has offered next to no information on this panel, though Blur Busters say it's an LCD display. OLED is catching up fast, with dual-mode 480Hz offerings from and LG coming to market in 2024, and 1000Hz prototypes possible within the next couple of years.

While this panel looks mightily impressive on paper, there are some caveats. The screen appears as though it's very much a proof-of-concept, with no information on what, if any compromises needed to be made in order to achieve such a refresh rate.

Then there's the question of whether DisplayPort 2.1 with Display Stream Compression (DSC) is capable [[link]] of driving such a panel, meaning a future DP 3.0 or HDMI 3.0 standard may be required to support such a refresh rate without crazy levels of compression or loss of color depth. And, you'll need a powerful graphics card and/or CPU to get anywhere near those kinds of frame rates. Some kind of next gen frame generation technology may be a prerequisite.

So, while this is an impressive feat by TCL, it's the kind of thing that'll have limited practicality for the foreseeable future. 1000Hz is more likely to debut at 1080p or 1440p resolutions before [[link]] we see 1000Hz at 4K.

Beyond gaming, I look forward to seeing what 1000Hz content would look like. Planet Earth 4 perhaps? By the time displays supporting 1000Hz at 4K become a thing, Sir David Attenborough will probably be 120 years old, and we'll be eyeing the next big thing. I want my wall sized 16K 1000Hz window replacement panel.
