Thanks. I suppose I should have known that. Sorry. I'm a bit new to the world of Mac and I've got a bit to learn. I have noticed that my HD tv still produces rather a grainy picture, - even wi my new DVI-HDMi lead. I expected it to be similar to the mac screen. Probably too-high an expectation!
Maybe - I had high expectations also. At least, I was hoping it would be as good as my XP box which has been connected to an HDTV rather than a monitor for about a year now. No dice. Movies look great, but text is just plain, well, bad.
Don't know what size TV you're connecting yours up to, but keep in mind, your HDTV has a vertical resolution of only either 720 or if you have one of this years models maybe 1080. The little 15" MBP screen is 900 while most any decent computer monitor at 20" will be 1200 and 30" monitors are 1600. So we still have big differences between TV and monitor displays.
Have only hooked up my MBP via DVI / HDMI since I'm using my only DVI / VGA cable on my main box because Linux does not work with HDMI. With OS X in the house now, really don't think I'll be using Linux any more so I'll switch cables around and try the DVI/VGA cable on the MBP to see if that makes a difference.
