If you thought 500Hz was extreme, think again: Chinese display maker TCL CSOT is pushing limits with a massive 57-inch PC monitor boasting a 1,000Hz refresh rate.
The company is showing off the monitor at the Display Week 2025 show in San Jose, California. In addition to the insane refresh rate, it also offers a wide 7,680-by-2,160-pixel resolution, similar to Samsung’s Odyssey Neo G9 ultrawide. As a result, the monitor has an 8K resolution in the horizontal dimension, but not along the vertical axis.
TCL says it can pull off the 1,000Hz refresh rate by using its “6G2P point-to-point driver” and proprietary CSPI 5.1 protocol, which is designed to achieve “higher transmission frequency and transmission rate” over other technologies.

The company built the monitor using TCL’s HVA technology, a type of LCD panel. Thanks to the monitor’s unusually long screen width, the concept product creates an immersive PC gaming experience that stands out from other displays. But good luck finding content that can fully take advantage of the monitor’s features.
To demo the monitor, TCL played a video showing two Roman soldiers battling each other. But a company representative told us the demo clip wasn’t hitting the 1,000fps rate. Even if it did, we’re doubtful we’d notice any difference. The other issue is that the latest HDMI 2.1b and DisplayPort 2.1b spec only supports 8K up to 60Hz and 240Hz, respectively.

As a result, the 1,000Hz boast feels like a marketing gimmick. TCL’s monitor is a prototype, making it unclear if it’ll arrive on the market. The company debuted a similar concept at last year’s Display Week with a more traditional 4K monitor that had a 1,000Hz refresh rate. The vendor has since expanded the concept to encompass a 57-inch widescreen.
