Thanks DrHu. (Sorry).
I guess my next question is? How do you tell if a card is a Vesa card?
Mint 7 picks up everything and takes it to the park for a nice walk whereas 8 just plays 'come get me' just as Karmic did.
(Not your fault).
I have two cards, both Radeon, both only show 800 x 600.
No worries I just thought I would ask. Thanks very much for the reply and the links, I'll go check those out.
Many thanks again.
