RTX 4080 experiences sudden disconnection from the monitor during operation
You're experiencing random display issues with your RTX 4080 SUPER, showing a black screen and "No Signal Detected" warning. Despite reseating the power cable and GPU, updating drivers, and using a reliable PSU (850W MSI), the problem persists during demanding tasks like gaming or CAD. It seems to occur more often when running GPU-heavy applications.
Do you have another cable to check, it might be a different cable or even the card itself—try another port on the GPU. Is your system stopping completely or is just the display going dark? You can use MSI Kombustor to put stress on the GPU. If it only happens when under load, it might point to overheating or a failing component. More testing is needed, and we'll require additional details.
