I have a 20.1" Sceptre. Scenario: 1. Turn on computer 2. Turn on monitor 3. Monitor stays black but the power light flashes on and off 4. Computer boots up normally 5. After 20mins-1hour, monitor finally displays desktop and everything works again ... 6. Turn off computer and monitor. Go to sleep. 7. Wake up, turn on monitor and computer. 8. Repeat steps 1-6. Add 30 mins to step 5 per day. (Up until now it takes a few hours for it to work. Right now it won't even turn on) *I have plugged my monitor into another computer that has no GFX only to get the same result.
