I have a dvi to dvi cable that goes from my monitor into my USB-C docking station, then I use a usb c to usb c cable to connect the docking station into my laptop.
My laptop has two graphic cards : One that is an Nvidia one and the other one is an Intel one. In order to bypass the intel graphics card while playing I use the "Only display second monitor" while playing in order to utilize my second screen, and max out on the Nvidia without utilizing the intel one.
Now I have a refresh rate of 239.6 hz which feels like it is the case when using this usb c to usb c cable. The issue is that I get black screens from time to time that cut audio and image for a few seconds. This can vary from 5 times in an hour to twice a day.
I thought the issue was with the usb c to usb c cable so I bought a new one supporting until 4K 60 fps but it keeps making my whole screen black and only works when I set the refresh the rate to 60 fps, and then also only for a few seconds... What can I do in order to not have black screens anymore ?
Is there a cable suggestion I don't know about ? Or is there a "bypass" that I don't know that makes the dpi to dpi the main transfer of image tool?
