News: GTX 1070 and 1080 DVI Pixel Clock Issues by Guru3d

Guru3d is reporting an issue with the GTX 1070 and GTX 1080. They report that you may have issues booting into windows if you have a monitor refresh rate of greater than 81hz AND are using the DVI port. The temporary fix is to just use Display Port or boot into windows safe mode and switch the refresh rate to 60hz or below 81hz. Click the photo or source link for their full repot.
