Me and many others with this same monitor (D2719HGF) can't get 120hz in call of duty cold war. In the manual it states 120hz 1080p is possible but it doesn't work. It works once hooked up onto a PC but not on the PS5. The HDMI is 1.4 and I am using the HDMI which came with the PS5. This has to be something related to the PS5's software. Please help wear awareness for a chance of playstation to see this thread.
