Hi
I have installed the Sony OEM, Omega and Catalyst drivers and they all do
it.
Reason I was interested is because thr DELL XPS Inspiron can do 1280x1024 on
a 1920x1200 screen with the same video card. I was just curious to see if I
could get the Vaio to do it as I'd like to run games at 1280x1024....at the
moment, most games make me use 1024x768. I realise 1280 isn't native or the
same aspect ratio but it would surely look better than 1024x768.
Cheers
