    Windows update ruined my HDMI output?


      My HDMI output has been working fine since I got my current laptop (Windows 8.1 64-bit), but last night Windows installed an update which destroyed all HDMI functionality. I've tried system restores and it didn't help, and all efforts at updating or downgrading my drivers have failed. My old laptop's HDMI still works fine using the same cable and output so I don't know what the problem is. Can someone help? DxDiag log attached.
