Monitor goes into sleep mode after a few seconds

When I turn my computer on, the monitor shows the Dell logo and then goes into sleep mode.  I cannot change any settings or adjust anything since the monitor goes blank almost immediately.  My monitor keeps going into sleep mode. Also when it flicks back on I get millions of little blinking pixels. I thought at first it was just the monitor but I've switched monitors, no change. What is causing this and how can I fix it?

This is normaly cause by incorrect power management settings.

check power management setting in both windows and your computers bios

you will not need to worry about the power management settings of the bios when an operating system such as windows is loaded.

My monitor seems to be stuck in sleep mode


This happens when there is no communication with video card. Check cables, re-seat video card, make sure monitor is set to correct mode. VGA (15pin blue), DVI (white), or HDMI.

Monitor goes black seconds after showing desktop


Does your monitor go black because it went to sleep, does it turn off? Do you have any lights on the monitor to indicate what it is doing?

Also I would boot into safe made by rebooting the computer & tapping F8 when the bios appears. You should be prompted with several options, one of which is "Safe Mode". Choose this & report how the monitor behaves.

Turn my computer and it starts up normally, however, the monitor never turns on. When I manually turn the monitor on it displays the Acer logo and then goes to the "no signal" screen for a few seconds...


Try the monitor on another computer or a friends computer, if it is working you may need a new graphics card.
Try the monitor first, if your unsure take the machine to a local computer shop for advice, or if you have a computer geek nearby ask them.

OK I have the same monitor, I was given it by a client when I couldnt fix it, I DO have the 19V supply and still getting the same problem.

If you open it and reseat all connections you can reach, I find it starts to work. Unfortunately after less than a few days use it goes off again.

Hopefully this can help someone get further
