on my Windows 11 machine I have 3 monitors connected to a GTX3080 Ti. The primary one is connected using DP1.4 cable and the other ones are connected using the CAC-1080 DP to HDMI adapter (reasons for this later, but this shouldn’t be the main topic here).
Everytime after reboot (or wake from hibernation/standby) the monitors connected using the CAC-1080 adapter are not recognized correctly. They appear as “nvfailsafe” monitor in the device manager and resolution is 640×480. Replugging the adapters on the DP side fixes this issue, but only until the next reboot.
I’m already running the latest NVidia driver, did a clean install of it, etc. Nothing helped so far.
I’ve as well tried out different DP to HDMI adapters (from Cable Creation) and these do not have this specific problem (unfortunately they have other issues which make them nearly unusable for me).
Is there anything I can do to improve this situation?
Reasons for using DP to HDMI as a workaround:
I bought 3 DSC monitors (that do not have an option to disable DSC) without knowing that NVidia cards are currently limited to a maximum of 2 DSC monitors.
