I have an Intel DH67BL desktop board (WIN7 pro 64bit) with an Acer S273HL LED monitor but sometimes the monitor shows 'NO SIGNAL' and after a few seconds it works again. What can be the problem?
Here are our recommendations for this issue:
1. Check for the connection on the motherboard and the monitor, make sure is not loose. You can test with a different cable.
2. Make sure you have the latest firmware update for the monitor and latest graphics drivers for the motherboard:
3. Test the system over a non static surface out of the chassis just to make sure there is no grounding affecting the system.
