2 of these video cards: XFX HD-577A-ZNFC Radeon HD 5770 (Juniper XT) 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card
One of my monitors is a Samsung Syncmaster T240 24 inch. My other is a 24 inch Westinghouse.
I have them both plugged into the same video card as I have crossfire running. Last night I just turned my monitors off (not my pc), then when I woke up today, I turned them both on, but the samsung, only stayed on for a few seconds (screen had a really dark tint) then it turns off. And it does this everytime I turn it on. I am stumped.
