Hey everyone, I noticed my PC has dead pixels. Could it be related to the GPU being faulty? After cleaning Windows and updating drivers, the issue persists. The monitor works perfectly on the Nintendo Switch but not on my PC. It seems like a possible cable problem. My specs are an i5-10400F CPU at 2.90GHz, 8GB RAM (originally 16GB, I had to replace it due to a blue screen after changing RAM, and dead pixels appeared before the BSOD started). I’m using a GeForce GTX 1660 SUPER. Any thoughts on why the dead pixels still exist? (Photo taken from my phone)
These aren't actual dead pixels. This refers to artifacts from the GPU malfunctioning. Dead pixels happen when monitor pixels cease functioning or freeze, yet the device still operates normally—this isn’t a monitor issue. It might stem from driver issues; you can attempt using DDU and reinstalling Nvidia drivers. Alternatively, it could indicate your GPU is beginning to fail. There are several steps you can take before reaching that conclusion.
Is the same cable connected to the Switch? If the GPU is functioning normally, the issue might be with the cable.
