Odd problem with Asus VG248QE [warranty claim]

[shadman]

Hey, I just went down to the local Fry's with my friend and he purchased a floor model of the Asus VG248QE (Sorry Chief, he didn't want to wait from Amazon). We get home, plug the DVI in and...nothing. Monitor doesn't turn on. Plug in HDMI, works just fine. To be sure, try the DVI again. DVI works until Windows loads, so BIOS works, and safe mode works. Anything else for DVI, nada. Tried a single-link cable, same deal. Took the monitor to my house, completely different (known good DVI cable, video card..the one for my OC Catleap) and I'm having the same issues! Looking on the desktop when the DVI is plugged (with Teamviewer), nowhere does it say anything about a monitor plugged in.

Can the DVI port really be bad on this monitor, in a way that it doesn't work at the OS level? Will have to but a displayport cable to test out DisplayPort, and see if I can get Asus involved, but is there something wrong with the EDID or something?


Side note: He is using a GTA 770 (don't know which specific model, but tried both DVI slots) and I have this card here: http://www.newegg.com/Product/Product.a ... 6814130768 Again, this rig/cable work with 1440p @ 120Hz, so I'm pretty dang sure its not my stuff..I think.

EDIT: Didn't want to bump the thread for an update, but Asus said just send it in for repair. DP works flawlessly, so because this was a display model, I'm going to assume it was just a damaged DVI port that was not letting the monitor fully work, but could in safe mode and on other inputs. Case closed I guess.

Very possible -- due to display model, it might have had a lot of wear on the DVI port --

So I think this is probably a damaged DVI port, which doesn't work properly (e.g. certain pins disconnected), and causes this specific problem. So, this sounds like a warranty replacement.
