Windows 7: Color anomoly on single monitor of triple monitor setup.

V43L1N · 30 Apr 2012

This one has me stumped, hoping someone can lend a hand.

(The rig in question is up to date in my system specs)

I currently run a triple monitor setup, all the monitors were purchased at the same time, and are the following model:
Asus VS247H-P 23.6-Inch LED Monitor

The three monitors are all connected to: XFX DD Radeon HD 695X (Cross-fired with an identical OEM/Model/GPU) All three are connected to a single card (which was tested out of cross-fire beforehand, and each card was tested separately)

The monitors are arranged as shown below:
1-DVI ========2-Display port to DVI (active adapter)======3-DVI
With monitor one being the far left, monitor two the center display, and monitor three the far right display.

The best way to describe the issue: There seems to be a single blue pixel on display 2 that stays in the same place, but this pixel does not show up when the color displayed is solid white, solid black, or solid red.

To rule out the usual suspects:
-All cables have been checked with new replacements (on two different rigs)
-Both cards have been tested and work properly (on two different rigs)
-The cards are NOT overclocked
-The display that shows the pixel has been tested as well (the pixel does not appear on my test rig)
-Disabling eyefinity does not resolve the issue
-Removing the second card does not resolve the issue

My question: What am I seeing? A stuck pixel? Artifacting?
Could the active adapter be causing the issue?
If it turns out to be a stuck pixel, can it be fixed?
Or is this a dead pixel, that will require an RMA?

Any help would be greatly appreciated

Sounded like a stuck pixel until you mentioned it doesn't show itself in solid black. It's possible it still could be though, have you tried any of the remedies?

Plug monitors 1 and 3 to the Display Port Adapter and see if the pixel shows up on those displays as well. It might be a faulty DP to DVI adapter or the DP on the card.

You can try this:

I have the same problem on an Acer monitor. Mine is still stuck but you may have better luck.

I gave that a shot a last night, no pixel on display 1 or 3. Thank you for the suggestion
