Topic - Dual monitor problems after power cut - please help!!

phja - on 02 Feb 2014

After much frustration I'm deferring to the wisdom of UKC...

I've got desktop pc running Windows 7 with Nvidia GTX 460 connected to an ASUS monitor (through DVI) and a Samsung HD TV (through HDMI).

All this worked fine as a dual screen setup until we had a power cut earlier today. At first it wouldn't detect the screen at all but now it has.

I've got it to detect the TV and it is showing my extended desktop. However its only giving me a resolution of 1024x768 rather than the 1920x1080 I had before. Plus its only naming it as "generic non-pnp monitor" rather than saying "Samsung TV" as it did before.

I've tried updating graphics card drivers and tried rolling back windows (with no luck as it gives me an error). I've also tried switching HDMI ports on the TV, one of which it detects but in the other port my computer picks up nothing!!

Anyone have any suggestions please??
