Samsung's Odyssey OLED G6 gaming monitor is available for pre-orders in Southeast Asia, with a global rollout scheduled for later this year. The monitor features a refresh rate of 500Hz and a 2560x1440 resolution. https://www.notebookcheck.net/The-world-s-first-500Hz-OLED-monitor-is-now-up-for-Pre-Order.1014192.0.html
Way too big. 500 Hz is completely unnecessary outside of competitive shooters and those same FPS games are mainly being played at specifically 24" (CS2, Val, Apex for example, just check live tournaments and it's exclusively 24" 240-480 Hz, literally nothing else but 24").
Is 500 Hz nice? Absolutely yes (judging from a 360 Hz perspective). Is it important to pay premium over 240 Hz to play, I don't know... Black Myth Wukong? Absolutely not.
