Hi guys,
So I opened my computer yesterday and my computer can't recognize my monitor. It is showing "Generic Non PNP monitor" with only 1024x768(native) and 800x600 resolution with up to 240 hz refresh rate ( but when you choose refresh rate higher than 120 hz, its saying out of range). So I tried all the solution that I know and that I googled. I reformatted my computer, updated my bios, install latest GPU driver/installing previous GPU driver, updated my BENQ monitor with the cd provided (going to device manager, update driver, have disk.....), do windows update, use a different DVI dual link cable, remove my graphics card and put it back on but nothing is working. And then I tried to plug in my wifes' monitor (BENQ XL2411Z) to my computer and her monitor work fine. I put my monitor (BENQ XL2420TE) on her computer and it says "no signal detected". I'm planning to RMA it to BENQ but I want to know if anyone got a solution or has experience this problem before.

Here's my specs:
I7 2600k
8 gb ram
EVGA 560 ti x2 (SLI)
Windows 7
