I've been using an XL2420TE for the past month and it's been fine, but today it started only displaying 120hz and below, when I try to use 144hz, (which I've been using for a while) it displays an "Out of Range" message.

I reinstalled the drivers and made sure all the display settings were consistent across the board, but no luck.

I'm on a Windows 7, a 780ti, a 4670k, and 8gbs of RAM, hooked up with Dual-Link DVI, so it's not a compatibility problem.

Any suggestions?

Thanks
