Lo all, having got a sapphire HD3870 for xmas and also treated myself to a Samsung 32" LCD tv, My tv is 1080i not 1080p
I run the 3870 through the HDMI cable. i am now left wondering can i run this card at 1920x1080 ? I know that if i was going through the vga port on the tv it would have to be that res of 1380x768 .
What is this card 1080i or 1080p or is it both ?

Thanks for any help....
P.S What a gfx card
