[HELP]240hz OLED Monitor only Shows 30hz and 60hz

[Gaodek]

Hi Guys.
My hackintosh is almost perfect, but I’m hitting a snag: my monitor only picks up 30Hz and 60Hz. On Windows, it runs smoothly at 240Hz no problem. I’ve tried different HDMI and DisplayPort cables, messed around with apps like SwitchResX, but still stuck at 30 or 60Hz. Any chance someone could help me out? I can share my EFI if needed.My setup:
Asus ROG Strix B650E-E Wi-Fi Gaming
Ryzen 7700X
32GB DDR5 XPG Blade 6400
Rx 570 4GB
Crucial P5 Plus 1TB

The System is Sequoia, But tested in Sonoma too.

My 57 inch samsung supports 240hz via DP, however MacOS and the 6950xt only supports 60hz at 7860 x 2160 via DP with HDR
