Ok so i am having an argument with a mate of mine who says i should use the hdmi port on my monitor instead of dvi for hd stuff.

I thought it made no difference, will 720 and 1080p look better on hdmi than it does on dvi if i am using mkv files?
 
dont forget.. hdmi cable is much more expensive ;) though it probably doesnt really fit into your argument :P
 
Killa bru, tell him to tsek :p
They are the same thing, as was mentioned above the difference comes in with HDMI delivering sound.
 
Very useful thread. I have been meaning to find this information out.
Thanks Killadoob

If you have HDMI on the gpu then I should say go with HDMI. it does have better bandwidth than DVI. also depends what type of DVI you using.
 
Well maybe it is a plcebo but i decide rather just to stop being lazy and i swapped the monitor i have at home with one from work cause it has hdmi, hooked it up at home and the 720p files look way better.

Miles better in fact i was thinking 720p is pretty darn silly compared to a dvdrip but now with hdmi hooked up they look insane, placebo perhaps?

One thing the text is blurry :(, everything else is cool but the text is not lekka any suggestions
 
Odds are it has more to do with the fact that the work screen's just better than your one at home :p
 
Maybe you're not running it at the native resolution?
 
Also, HDMI has HDCP, and some devices (PS3) won't deliver full quality to the monitor if it doesn't find HDCP.

DVI signal quality may be the same, but it doesn't have HDCP.

I had to buy a special gadget to get Full HD into my slightly older 42" plasma (which has DVI, but not HDMI). The gadget converts HDMI to DVI (but has HDCP).

The PS3 (which I use as a Blu-ray player) refused to send a HD signal to the DVI port (I initially just used a HDMI -> DVI Adapter).

BS. Of course DVI has HDCP. That's the entire POINT of making the switch to a digital connection and moving away from component - so that they can encrypt the signal for copyright protection. Before HDCP, DVI didn't even exist in the TV arena.

DVI existed long before HDMI.

And it cost me more than USD100 to get HD quality on my non-HDCP plasma (only DVI & Component)).

HDCP is part of the HDMI spec, computer monitors don't have HDCP (unless they have a HDMI port, which a few do).

Note :

OK, I have just checked, some of the later DVI implementations do have HDCP.

My Sony 42" plasma's DVI DOES NOT have HDCP, it says so explicitly in the manual. And the PS3 won't send HD to it for that reason.

Not sure which computer monitors will/won't have HDCP (on their DVI ports), there is a royalty implication, so I guess that the cheaper ones won't have it.

I had to buy this to get my display to work properly with a PS3.
