My current monitor is a 21.5 inch Dell S2240L monitor, I use an HDMI cable for it. Sometimes, I bump into my CPU and the monitor goes black and replugging the cable in both the monitor and the CPU doesn't help. I have to restart my computer to get the monitor working again.
It shows "HDMI cable is not detected, this display will now shut off in 5 minutes". Is there anything I can do to fix this (I cannot move the CPU, that's how the desk is built.) Thanks!
 
Solution
sounds like your vide card is not screwed down tightly or possible loose power connector from psu to video card if it needs 1.
