Multiple Monitors going to sleep on their own...

By michael.burgess ·
We have recently rolled out a lot of equipment to multiple stores. Everything has been working fine for months. Recently, some but not all of the monitors seem to be going to sleep on their own.

I have checked all of the power options and they are turned off. This is affecting different monitors and all of these machines are from the same image... even the one's that aren't experiencing the issue.

Any ideas? I have searched google and checked everything on the PC.

Have you checked the monitors?

On some monitors there might be a timer so that they shut down at a certain time when not in use.
Hope this helps..

Yeah I've checked. I have actually replaced one monitor with a different model and the same thing is happening.

Group Policy

Do the companies that are experiencing this problem have Group policy objects, if so see if the computers in the group policy's monitors are the ones in question. As i have seen mistakes made to make this happen in GPO.

Ok have you tested the monitors on their own..

Because this is a very different work around.
The monitors seam to be losing power somewhere so if i were you, see if you can check them with a power tester. What make are these monitors by the way?.
Hope this points you in the right direction.

Please post back if you have more problems or questions.

More info.....Thank you Phil

The monitor will restore its self if you unplug it. That being the case I would suspect that the driver for your video card is suspect. I would try downloading the latest drivers for the mother board, video card, and monitor. If this fails then either the Monitor has its lowest resolution decoder chip failing or the video card is failing. The reason the monitor is flicking off and on is that it is not sure that it is getting a vertical and horizontal signal from the PC. It then goes into shut down. The only reason this may be an errant diagnosys, is that the led on the front of the monitor, "Light", turns off as well. If it is turning amber or yellow, then this is the correct diagnosys, and the video card is likely the cause. Also be sure that the data cable from the monitor to the PC is fastened tightly to both connectors if you have connectors at both ends, if not at the PC.

Please post back if you have more problems or questions.
