u/Temporary_Process_37

I just got myself a Play Gradient and a sync box 4k (old one) to use it with my pc. I know this sync box handles 4k60, and qhd fhd 120hz. The problem is that it works well on 60Hz, but not on above 60Hz, even though it is on QHD.

First of all, my monitor is 240Hz(but I usually play games between 90~120), so I set it to 120Hz in the Nvidia settings, but the hyu app just says "Ready" and the light on the strip isn't coming on. When I set it to 144hz it clearly says that it is not supported. But between 70~120Hz, it lets me click the button, but it doesn’t work at all.

Any idea what is going on?
