Companies have been going above and beyond 500 Hz in recent years to push the limits of refresh rates in gaming monitors. They are going after even higher frequencies now. Interestingly, this advancement is no longer restricted to panels with resolutions of 1080p or 1440p. The world’s first 4K 1000 Hz panel was just unveiled by the Chinese company TCL CSOT, indicating a major advancement in display technology for gamers.

The TCL CSOT booth is organized into ten technology areas, including HVA, HFS, MLED, MLCD, FMM OLED, and IJP OLED, each highlighting their latest advancements. Attendees can explore products such as the 85” UD w-HVA Pro, the world’s first 7.85″ Tandem Trifold Screen, and 14″ 2.8K Inkjet Printing Hybrid OLED Display. Other highlights include the world’s Highest CR 4000:1 HFS MNT, the world’s Highest Resolution 16″ 8K Laptop Display, and Ln-Oxide 14” MUX 1:3 Display. TCL CSOT will also showcase 7.85″ Under Screen Face Auth Display, the world’s first 57″ 6.9mm Thickness MLED MNT, and the world’s first 4K Highest Refresh Rate 1000Hz MNT.


The fastest monitors available today use TN panels and have a refresh rate of 540 Hz. Because of the limitations of available bandwidth and display technology, these monitors frequently have lower resolutions. Still, improvements like the DisplayPort 2.1 standard—especially in UHBR20 mode—can provide 884 Hz refresh rates at 1080p resolution without requiring Display Stream Compression (DSC).

DSC 3.0 compression technology has made it possible to achieve a refresh rate of 540 Hz at 1080p resolution with only 15.5 Gbit/s, which is well within the 77.3 Gbit/s available bandwidth (UHBR20).

Blur Busters, who visited the TCL booth and took the photos, explained what’s required to support such high frame rates. While a more powerful GPU may seem like the obvious solution, with frame rates already reaching the hundreds, frame generation or interpolation can be seen as a viable option.

Using contemporary game engines and 10:1 frame generation technology, the goal is to produce a visually stunning experience that is as lifelike as possible. Similar to the objectives set for video encoding technologies, the ultimate goal is to guarantee a lag-free and artifact-free experience. A very close collaboration between display panel makers, game developers, and GPU vendors would be necessary. It looks like TCL CSOT has already taken the first step.
