Check your power settings (run>control>power options>change plan settings>advanced options>display)
you will see the setting for your monitor to power off
it should be set to 2 hrs or more if you plan on watching a movie or keeping the monitor on without having to frequently touch the keyboard or mouse.
turning adaptive display on may affect your situation as well. try switching it on.

This should do the trick for you. If not you may have an issue with either your video card or your monitors power supply.
(if the light stays on on the monitor when it goes blank but it doesnt repsond to the mouse or the keyboard, its a setting on your system or the hardware itself)
Good Luck!!

If you get a flashing screen which show your screen for few minutes and then goes blank it may be an issue with the Monitor.

Try to restart the computer and go to BIOS setup screen. If you experience the same issue in BIOS then the monitor needs a repair or replacement for sure.

Asus Monitor boes blank and comes back after power recycle


1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.

Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.

Multisync LCD 1700V turns on then screen goes blank and shuts off


Does the power light stay on? If so, you have an inverter problem. If the power light goes off, you have a power supply problem.

Acer AL1711 17" LCD Monitor goes blank without warning


The need to reboot your computer to get your monitor working places the blame totally in the computer. You have a virus, or the computer is overheating and shutting down for thermal reasons.

This is a problem usually with the Power Supply unit inside the Monitor. Often it is the Electrolytic Capacitors arround the Heatsink area. They dry out and go faulty.. It is generally a job for the "Shop" I get them all the time... But in saying that intermittent faults are the hardest to find.. If you do take it to a shop, ensure you get a firm "Quote" and explanation B4 proceeding.
