Thunderobot is now offering a gaming monitor based on new OLED display panel technology. Not only does the monitor combine a 4K resolution with a 240 Hz refresh rate, but it can also run at 480 Hz by dropping its resolution to 1080p.https://www.notebookcheck.net/Thunderobot-releases-new-480-Hz-OLED-gaming-monitor-that-also-supports-4K-output.837114.0.html
Should be able to achieve 960Hz at 1080p if it has the bandwidth for 4K 240Hz. Resolution scaling complexity is quadratic, not linear!
Still useful to have these two modes.
