Acer Monitor Enters Power Save Mode

Acer / H233h

Specs: Windows 7, 2.66 GHz Core 2 Quad/4 GB RAM
Hello, I have a homebrew computer that has an Acer H233H monitor w/DVI connection, EVGA nVidia GTS 250 video card and Windows 7.

I am watching movies and I am noticing that every 20 minutes the screen goes black, I get the "no signal" message on the monitor and the power light goes amber. In order to get a picture again I have to move the mouse.

This process is starting to get a little annoying for me. I went into Windows 7 power settings and set the monitor sleep interval to "Never", but nothing changes. I also went to the nVidia Control Panel but there were no options listed for power save mode.

Would appreciate any assistance as to how I can get this monitor power save situation out of the way. Thanks.

Check your M/B manual for BIOS power-saving settings, CPU Intel C-State Tech settings, etc. These settings have additional power plans besides Windows.

After you change power plan settings in Windows, you may have to restart ( highly unlikely ) Windows for the changes to take effect.

Thanks. I went into my BIOS (I have an ASUS P5Q Turbo MB) and the only thing I was able to verify was that the C-State was Disabled. There were no other power-saving options that I could see in there. Any additional help is appreicated.

Did you try the menu buttons on your monitor (not too likely, but possible) and did you try updating monitor drivers? Also, if you have 2 DVI connectors on your video card, try the other one (again unlikely, but possible).

The pop-up menu on my Acer monitor does not have any options for power saving. I will try my other DVI port when I have some more free time hopefully this weekend. Any other suggestions?

I tried the second DVI port and the screen still goes blank after 20 minutes.

Regarding monitor drivers, I attempted to download the drivers from Acer and then apply them, but Windows apparently said that I already have the best driver for the monitor: Generic PnP.
