Basic question. How do I ensure I am pixel mapping my PC to my Sammy LE40R74? Is it just a case of setting the desktop to the same res as the Sammy (1366 X 768 ??).
Yes, assuming the Panny supports 1:1 pixel mapping. You will have to select 1360x768 which means loosing 3 pixels on either side but this won't show. This has something to do with the graphics card only being able to deal with a horizontal resolution that is divisable by 8.
A good way to check if you have acheived 1:1 mapping is to use the Nokia Monitor Test program, which is basically a test card generator, and shows instantly if the display is doing any scaling. You can download it here.....
Mine runs at 1280x800 when on laptop display but when connected to the tv can output at 1360x768. Make sure the pc is connected to the tv and it isnt in dual display mode and only outputting to the tv. That should be all that is needed to get it to output at the tvs resolution unless its serverly old . Failing that update to the latest drivers and try again.
