[QUOTE="knutinh, post: 111407, member: 14776"] If you connect your LG tv at 1:1 pixel to your PC and a SD tv picture is displayed at approximately fullscreen, then there is no doubt a scaler involved, as a PAL/NTSC picture would fill only a small rectangle of that screen unscaled. If you want to switch PC resolutions adaptively you may want to investigate the small mediaportal plugin RefreshRateControl found on the website. Also, powerstrip will come in handy. What is the reason that you are asking this question, are you not happy with the scaling quality? Did you try FFDShow?
