I'm trying to set up a TV as a second monitor via HDMI, but I'm having some issues.

1. Whenever I set the TV refresh rate to 60Hz, after an extended period of time, it will revert back to its default 30Hz, interlaced.

2. The picture quality is a lot worse than my main monitor (VGA) with everything having a grainy look.

Any help will be greatly appreciated.

I think my TV does support 1080p60, but the problem is that it changes back to 30 after an extended period of time (usually after I turn my PC off).
