Hello people, I've had this issue for a while now, but this week I took my computer to a service store and they looked at the various graphics abnormalities. One big abnormality was that the second monitor I use was suddenly no longer detected by Windows 10. It's been connected via HDMI and detected just fine for a while, using Windows 10 from the beginning. In "Display Settings" it doesn't appear automatically, nor does it appear when I hit "Detect". Using the various option in the menu that appears when I press the Windows key along with P is, again, fruitless. Updating drivers doesn't do anything. The guys at the service store said they checked the HDMI port with a cable of their own on a monitor of their own and it works just fine. Now that would mean that my cable or monitor might be bad. That isn't the case since I can connect without issue my Windows 10 laptop to that same monitor using the same cables. So what the hell is the problem? Any help would be greatly appreciated.
