I was wondering the same thing, but with regard to LN-S5797D model. Essentially they are 1920 x 1080 native resolution, but since there is no mentioning of 1080P support, i assume the visual content is being deinterlaced, which in turn brings me to the question of how critical is the impact of deinterlacing with regard to gaming on a pc with predominantly progressive-scan video cards... I called samsung to find out if there will be a problem using this tv as a pc monitor, but they simply refused to answer the question, only saying that it is not intended for computer use. So then i went to BestBuy's Magnolia center, but neither they had any clue, however, they've suggested that i'm more then welcome to bring over my computer or game console and plug it in to see for myself what's going to come out of it... If i can find a powerbook i could borrow from one of my friends, i'll immediately test it with that LN-S5797D, however, if anyone have already had experience playing any fast moving game on one of these two tvs please let me know.
