    I have a 15" MBP and running 10.6.8 and connecting to a 24" Sony Internet/Google TV via miniDisplayport to HDMI. Connecting is not the problem. The main problem I am having is the picture quality is real grainy and the fonts have a halo effect around them. Also the response time for the mouse is real laggy. Not a crisp picture at all. I have connected to a Samsung LED tv and have the same issue. But if I connect via minidisplay to VGA on the Samsung it looks great. My new Sony tv does not have VGA only HDMI. Any help would be great. Thanks.

    It could possibly be a bad adapter. Have you tried using a different adapter?

    I have tried the belkin minidisplay port to HDMI and another offbrand adapter. The belkin I bought at the apple store. They both are doing the same thing.

    Have you tried connecting it in 'clamshell mode'?

    That's a pretty common issue. I heard somewhere that VGA inputs are cleaner because the HDMI signal gets compressed somehow.... I'll have to look that up again.
