I'm using a EVGA GTX 680 with 3 BenQ XL2420TX monitors. When I first got the monitors everything worked properly and I was getting a smooth 120 fps on all 3 screens. I mounted my screens a couple months later and ever since I plugged them back in I cannot get the old cable setup to work properly.

I was using a display port on one screen, and dvi d cables for both the dvi i and dvi d outputs on my card. It worked fine until I mounted the monitors. Now the dvi i port works in my OS but the dvi d port only works in my bios, but only if the dvi i is unplugged.

I have troubleshooted every cable combination possible and even RMA'd my card, only to have the same issue. I have ruled out faulty cables and bad output ports on the card

I think you're making a bad decision on not purchasing another AsRock. Failures happen with all manufacturers, and AsRock doesn't get failures any more often than any other company. I would talk to AsRock support; you could probably get them to at least examine and repair the motherboard for you.

For what it's worth, I've worked with a lot of motherboard brands over the years, building for clients... there are only two brands I won't touch, both for video cards and motherboards. Those are MSI and Gigabyte. MSI tends to have a higher failure rate; they've got good products and good customer service, but the chance of getting a dead part is higher, and that pisses people off because it takes more time. Gigabyte has absolutely awful...

Yes, I have tried every cable combo possible with my setup. As well as having an all new card installed. The output does work, but only during bios and only if the other dvi port is unplugged. It seems like its something within my OS but I'm not for sure. I don't know too much about how all that works.

Seems that way, its an Asrock z77extreme 4 I believe, and only about a year and a half old. I will not be purchasing another Asrock! Luckily my second slot isn't in use for SLI right now. Then again this wouldn't be an issue if I did have SLI.

Gigabyte has absolutely awful customer service which, as far as I can tell, is staffed entirely with imps.

True, I guess it depends on what I'll need in the future and who has the best price. But this whole ordeal at least taught me how good EVGA customer service is. I'll probably use EVGA for graphics cards from now on

Yep. I only buy from EVGA and (to a lesser extent) ASUS for graphics cards. ASUS service can be a pain sometimes, but you usually get there. EVGA is a snap. Their warranty used to be much better, with a double lifetime AND covering watercooling, but I can't hold it against them for dropping that; it must have been rather expensive.
