I recently noticed my screen flickering with random pixels after purchasing a new monitor. It begins as isolated spots, then expands over time. Video of the problem: https://imgur.com/a/NAG4X1b I've tried various solutions: switching cables, using HDMI instead of DP, testing another monitor, changing the GPU, adjusting PCI-E connections, using different RAM sticks in various slots, replacing DP cables with VESA certified ones, and even getting a completely different monitor. I've also returned my new monitor for an RMA and tried multiple updates, including after switching GPUs. My hard drive failed a long test, but I'm unsure how that might relate to the display issue. (Delivering a replacement) I'm running out of ideas about what could be causing this.

Details: Asus ROG STRIX B550-XE GAMING WIFI (latest BIOS v2803) Ryzen 5 5600X ASUS TUF Gaming GeForce RTX 3090 CORSAIR Vengeance RGB Pro DDR4 3200 (2x16) SAMSUNG 970 EVO PLUS M.2 2280 1TB Corsair 1000w PSU (RM or HX, I can't remember which) Some extra info about the monitors: Two LG-27UD69P and one ASUS-XG27AQM, all linked via display ports. Two 4K and one 1440p. After switching the GPU to a 3090, nothing changed. But when I switched from an Acer Nitro 1440p to the Asus model, the issue improved slightly. There are only a few flickering pixels now, and they don't spread as fast. A single green pixel stays in the same spot each time, plus a few more that turn blue or green as the problem worsens. Any suggestions would be appreciated. I suspect the new GPU might be faulty, and the monitor too, but I'm not sure.**
