Yesterday I got a new TV (SAMSUNG 48inches). I connected my laptop to the TV via HDMI cable, but I get a problem. Anything on the pc's screen doesn't appear on TV and anything that I open afterwards appears on tv but not on the laptop. I tried replacing the hdmi cable, but I still have the same problem. My brother's laptop works perfectly with the Tv (so the problem is not with the TV itself) and my same laptop works perfectly when connected to another TV (also SAMSUNG but 50 inches, so the problem isn't from my laptop). This is driving me nuts. Any solutions?
