I recently bought Asus N53SV-X5MS. I tried to watch full HD movie from TV with resolution 1980x1080. When I started the movie it was laggy and I noticed that computer has not changed to high perfomance video card. So can anyone tell me how can I change it manually or what I am supposed to do.
The integrated HD 3000 should be more than adequate for movie watching. What program were you using? Some programs use cpu decoding by default. If you want the dedicated card to activate for that program, there should be a setting somewhere to add that program to a list.
