RE: Custom Resolution Utility (CRU)

Both the PC and the TV have 4K support but the PC would only recognize it was going up to 1920x1080 (which worked fine btw). Anyway, I downloaded the CRU software and I added the resolution for 4K to the TV, and suddenly Windows finally recognized the 4K! Good news right? WRONG! As soon as I selected the 4K setting in the Windows Screen Resolution menu, I had sealed my fate. Since then (about 7 hours ago) I have not seen a flicker of screen from my PC on that TV. All of the input settings are correct and the TV still works with other HDMI devices. I'm honestly stumped as to what went wrong. I have tried doing the reset all, but my PC still see's the 4K resolution of the TV and won't display, even after I change it back to 1920x1080.I don't see how that's possible. CRU only creates EDID overrides, and running reset-all.exe removes all overrides, so there should be nothing left. You can also use the "Delete" button at the top in CRU to delete the override for the monitor. CRU will show a * or ** for the monitor if an override still exists. Make sure to run restart.exe or reboot after removing overrides. You didn't mention what video card you have or what settings you used, so I have no idea what went wrong in the first place. 3840x2160 should have worked out of the box if your video card supported it. The only thing I can think of is you used the pixel clock patch, which you didn't mention doing, and that caused the driver to allow the 3840x2160 resolution already defined by the TV, but apparently your video card can't handle that, so that's causing your problems. If that's the case, simply restoring the unpatched driver will fix the problem. If for some reason that still doesn't help, then use DDU to completely uninstall the driver: http://www.wagnardmobile.com/DDU/ddudownload.htm |
