Dual Monitor issue one of them goes blank after a few minutes

I am running Win 7 Pro x64, i7, MSI Twin Frozr II R6870
1st Monitor is a Dell SP2309W (dvi on video card to dvi on monitor)
2nd Monitor is a HP W2338 LCD Monitor (dvi on video card to hdmi port on monitor)

The 2nd monitor (HP) goes off after a few minutes, but if I'm playing a video on that monitor the sound is still plays, so I know it's still running in the background. I noticed that the picture on the monitor doesn't fill the whole screen like my 1st monitor does. So I checked the resolution and it's set the highest resolution it will go.

I've checked the power settings by setting everything to never sleep or hibernate. I also checked the Graphic settings, but everything looks fine. I also updated the drivers for the video card. Both monitors are set to 60htz because that's the highest it will go.

I'm just puzzled can anyone give me ideas on how to fix this issue?

Thanks

Same issue with 7 64 bit but with a Acer laptop and external display/vga connection.

Work for a minute or 2 and goes blank, power light turns orange.

Tried everything except looking in bios get's that is next.

Just try to turn off DCR function of the monitor if it has the option. It worked for me!
