i need fuser setup help

hello guys,
I recently bought a new 27-inch OLED 4K monitor. I can't set it to 1080p 240Hz; the maximum I can set is 120Hz, and the HDMI signal drops when I open a game. Can you offer any support, free or paid, regarding this issue?

Are you using Display Port or HDMI cables? Also, does the fuser support DP? If yes, it shouldn't have issues.

Sounds like a bad fuser

Use Display Port instead of HDMI. HDMI is probably why you’re stuck at 120Hz and getting signal drops

probably need a better fuser.. what alot of issues have issues with OLED
