Monitor #2 washed out.

At my wits end here. System:
Dell 660
Windows 7 64-bit Home Edition w/SP1
8GM RAM
Corsair CX600M PSU
Brand new ASUS GeForce GTX 960 video card
#1 ASUS VS248 monitor and #2 ASUS VS242 monitor
1 each HDMI and DVI connections

Monitor #2 has colors 'washed out.' I can physically switch monitors and even switch inputs and monitor #2 always has colors washed out. Makes no difference which monitor has which input or which monitor is designated #1 and #2, #2 always washed out. For example, an Excel spreadsheet that looks perfect on monitor #1 looks like old, yellowed paper on #2. Black text seems to have a green haze.

One person suggested either the car was bad or the PSU was bad (well, he called it junk to begin with). I just replaced a GeForce GT620 card with the GTX 960 thinking I needed a more robust card. No change and I used the PCI power connection from the PSU to power it. I even disabled the onboard video via the Windows Device Manager, no joy.

Both monitors are set to

I began noticing the problem when I had the GT620 card, the ASUS VE242 monitor (with DVI input) and an older ACER monitor with VGA input; the ACER showed washed out colors as well. Bought the ASUS VS248 to replace the ACER thinking the ACER was going bad.

Could it really be the PSU or is there another avenue to explore? I hate to spend another $250-$300 for a PSU if it's not needed.

Thanks...
