TCL CSOT is rumored to launch a 4X dual-mode gaming panel with up to 640 Hz

If dual-mode monitors with 320Hz refresh rates aren't enough for you, TCL CSOT might be cooking a new display panel that will take these monitors to the next level. TCL CSOT, one of the major display makers in China, is reportedly planning to introduce a new dual-mode esports panel with 4x refresh rate switching. According to IT Home, the new monitor will offer refresh rate switching from 160Hz to 640Hz, with a launch window around Q3 2026.

This isn't our first dance with dual-mode monitors, but with conventional ones, your refresh rate typically doubles when you switch to a lower resolution. A 160Hz-to-640Hz jump would put TCL CSOT in a small group of panel makers pushing 3x- and 4x-dual-mode designs instead of the usual 2x setups.

Detailed specifications are scarce right now, but the monitor will likely offer 4K resolution at 160Hz and switch to an ultra-high-refresh 640Hz mode at 1080p. As for the panel type, we'll see whether TCL CSOT adopts IPS or OLED. Given that the company is one of the leading OLED manufacturers, an OLED panel is a real possibility. ASUS uses an IPS panel on its ROG Strix XG27UCG Gen 2 with 3x refresh rate switching, so an IPS option on TCL's model isn't off the table either.

While this is still a rumor, it fits well with TCL's recent monitor roadmap. Earlier this year, the company showed off the 32X3A, a 31.5-inch 4K OLED model with 240Hz and a dual-mode 1080p 480Hz option, and also listed the 27C3A Pro with a 4K 165Hz panel and a 1080p 320Hz mode. The 27-inch 27P2A Ultra was also showcased with a native 1440p panel at 550Hz and a dual-mode path to 1040Hz at a lower resolution. Based on that, it's not a shot in the dark to say that TCL's strategy this season is to go all out with aggressive refresh-rate scaling.
