I didn’t think VGA supported full res Blu Ray?

No, I think you misread my meanings. At thend of the day, I wanted to run Films or music from PC to telly.
I gave up. Got a refund of cabling.

I tried every possible method to get what I wanted. Surfed several websites, 99% of which said it is plug and play, just press F10 to throw the image to the other screen etc. or use “Set up TV as a 2nd monitor” mode.
All I could get on the big telly was my desktop backround photo with no icons. Yes, I unticked the box which says “Show my desktop on TV”.
When I did get it to show my PC screen on the big telly, it also changed my monitor res. to 1024 x 768 because it would only run in “Dual” mode. This was the only res. the TV would recognise, and is also what most of the websites suggested.
This was not the solution I wanted, having to change my res. back, and replace all the icons in correct order etc. was a total PITA.
Furthermore, I assumed my Graphics drivers must be yonks old. So I downloaded the latest.
BLUE SCREEN OF DEATH, looking for the nv4_disp.dll file. I found 3 of these files, in different locations.
Reloaded after BSD recovery, Same.
So, I restored the whole lot to a restore point from a fortnight ago, downloaded some older drivers from the Nvidia archive section, moved hte newer drivers in my “Ready to delete when I’m really sure directory” and all is well.
So, I reckon the latest Nvidia drivers are not compatible with the older drivers for the MOBO…does that sound right?
I don’t fancy updating mobo drivers. The situation is, the PC is stable and working..LEAVE IT BE!

I wrapped up the cabling as neat as I could, reboxed it, and was refunded by Maplins. Saga over.
