Screen lights up when GPU is active beyond browsing. Assistance needed!
It began last night when I connected my TV as a third monitor for gaming. It started randomly whenever I used an app or game that uses the GPU. A video at https://www.youtube.com/shorts/0RYviNfjlBc demonstrated the flashing effect. I ran 3D Mark to check the response and it immediately began flashing even though temperatures stayed below 60°C. My card hasn't failed yet, and changing monitor ports didn't resolve the issue.
The blinking pattern moving across the screen suggests a cable problem, though it appears consistent across multiple displays. However, since this occurs on several screens, it’s unlikely to be a simple cable issue. It may point to a GPU failure. I’ve already tested it in a different PCI slot and adjusted refresh rates, but further investigation is needed.
