My issue is a bit peculiar. Before composing this post, I conducted extensive research on the matter, but I believe my problem is somewhat unique.

Problem:

As the title suggests, my monitor occasionally fails to display anything. This can happen when I turn on the monitor, whether the computer is already running or during the boot-up process (although not consistently). To resolve this issue, I have to remove and re-attach the HDMI cable, and sometimes this solution works, while at other times it doesn't.

Yesterday, when I couldn't get any display, I decided to replace the HDMI cable. After installing the new cable, it worked, and I thought the problem was solved. However, the same issue reoccurred today when I restarted my PC for an update. To regain the display, I had to open my PC and re-attach the cables, and now I'm writing this post.

Please note that even when there's no display on the monitor, I can still use the PC blindly. This includes actions like launching games, playing music, and even shutting it down using shortcuts, such as Win key + X > U > U.


So, what can be the problem? Is it the monitor or is this an issue with my GPU? Can GPU even cause this type of issue such as failing HDMI port.
