A little off topic

I posted this on the Cubix forum:

Im trying to get to the bottom of this problem with Dual 30 Apple Cinema Displays hooked up to a Gefen DVI-DL Dual switcher.
With the Cubix housing RED Rocket, BM Decklink, Quadro 4000 and the Mac Pro 2.93 with ATI 5770, ATTO R680, Cubix host and Avid HBA (Nitris DX), Im getting a this weird display anomaly where multi-color pixels show up in the blacks and only on the blacks on only on the left monitor.
We also have another Mac Pro 2.93 with ATI 5770 sharing the Gefen and dont seem to be having the same problems.
Now I bring this up here in Cubix forum since it only happens when the Cubix is attached to that Mac.
Anyone else experience this?

Sorry about that.
