Using an HDTV as monitor through hdmi

I know it's possible, but i was wondering how the tv would behave- like a dvi monitor (the computer can detect it, set the applicable res etc). Im hoping to get a full HD 1080 tv and, using a DVI to HDMI cable, use it as both a tv for a ps3 and as a secondary display for a mac pro. Seeing as HDMI is DVI+sound, i would imagine it would behave almost identically to DVI, but i'm not too sure. Are there any image quality issues etc?

I scoured the HDTV post, but coudnt find anything answering this question...

It will work, however, there are a couple of issues.

First - the EDID - the info passed to the connected devices - this has not been standardized with the HDMI specification for using this connection with a computer - so whether OS X recognizes it and auto sets the correct resolution probably will not occur - this is not so much of a problem as you will be able to set the resolution in system Preferences for the desired output.

Second - The way OS X handles fonts leaves something to be desired when using an HDTV as a monitor. Movies and games look OK, but in comparison to XP, all text looks really bad in comparison. It's readable, but just not clear. I have and/or currently use 26", 32", 55" 720p HDTV's as my primary monitor on my XP machine. Have been for 2 years. Got my MBP 6 months ago and have read and researched much regarding this issue and have found the same problem reported, but no resolution anywhere.

Cheers, i will primarily use it as a the preview monitor for FCS edits, so font sizing isnt really an issue.

That should function adequately

WOuld image quality be as good as say a bluray movie from a bluray player through hdmi?

I actually do not notice that much difference between using the VGA and HDMI connections.

If you are talking about watching a standard DVD from the internal drive - no, the DVD is still going to be 720 x 480 (720 x 576 PAL) and that is the best you will get. When playing them on your computer they get upscaled to match the resolution of your screen - this is not the same as if the recording were in 720 or 1080 to begin with.
