Specs: Windows 7

I have dual monitors and the second screen turns black and says D-Sub power saving mode. I have turned off all power saving modes on the screens and sleep timers on the computer. I have also tried other screens. i have recently upgraded from 400W to 600W pc power supply and am still having the same problem. Can anyone help me out. 4 month old computer really frustrating!!!

✔ Best Answer

Try a different signal cable to the affected monitor, and ensure monitor driver (just an information or INF file) from monitor maker is installed.

When the monitor driver is installed, monitor make & model appears in Device Manager. If it says "Generic" monitor, the driver hasn't been installed.

Look under advanced power settings. I see a PCI express listing. Check that out.

Nope had no luck guys it just dipped into power saving mode again. I have no idea what else it could be. Only other thing i could say is there an NVIDIA setting that i have to change to be able to have dual monitors?

I assumed you were already using the nividia settings. Did you look at the setting I mentioned above? Go to Control panel> power options> change to> My custom plan> change plan settings> set the turn off display to desired time> Set sleep to NEVER> Click on> change advanced power settings> expand PCI express> Link state power management> OFF.

Not sure if that setting refers to multiple graphics cards or not but worth a try.

I have a Samsung monitor that has a driver installed but it shows as generic PnP display in Windows 7. Didn't do that in XP.

I havent done anything to my NVIDIA settings. I go into nvidia control panel and it brings up dual monitors on there so it is detecting them and i did the PCI express thing but it still does the same thing.

You don't want maximum savings. Just the opposite.

Then you don't have the power saving features all turned off.

Are you using the monitors in clone mode or independent mode?

Are the monitors identical? Are you running off integrated graphics?

Provide details of you hardware.

See if the link below is of any help to you.

Where can i find out about the clone more or independant mode?

I dont know what you mean by identical or intergrated graphics sorry.

That link is what i am thinking that is the problem that i havent set it up through NVIDIA settings but is for XP i am running windows 7. Have had a look online for the same with windows 7 but cannot find it.

My last resort was to call up and speak to NVIDIA and ask them if there would be a problem with the graphics card.

My specs are as follows:

Windows 7 Home Premium
Processor: AMD FX(tm)-8120 Eight-Core Processor
16.0GB ram
64-bit operating system


Device management details are:

Computer-ACPI x64-based PC
Display adapters-NVIDIA GeForce GTX 550 Ti
Monitors-LG E2242(Analog) LG E2351(Digital)

Is there any other specs you need?

Do you have more than one GTX 550 Ti?

Your monitors are not identical according to your model numbers.

Your graphics adapter is NOT integrated but an add in card.

Clone means both monitors show the same identical image.
