I have tested my system setup with another monitor that has the same resolution and frame rate with no loss of video. The only difference is that the DP port on this other monitor is 1.4. Based on this, the DP1.2 on the DELL monitor must be the issue. I think my best option is to return the monitor since there is nothing I can do about the version of the Display Port.
I recently bought a G2722HS gaming monitor that has been blacking out for 1-2 seconds while gaming. I bought this G2722HS because it was supposed to support 1920x1080p resolution at 165Hz. I am driving this G2722HS with a Nvidia 3080 GPU with all the latest drivers. After hours of tweaking monitor and game settings, I discover that the built-in DP is version 1.2. To my knowledge, DP1.2 can only support 1080p 144Hz. Is this assessment correct? If so, Dell's claim that this supports 1080p 165Hz is not true.
