I got a full HD monitor yesterday, W2361V 1080p LG, and have been watching some youtube 1080p videos today, but I'm not sure if it's just me, but visually the trailers I've seen, and a few I downloaded, don't appear to look as impressive as I remember when watching say a blu-ray movie or playing a game in HD on my ps3. I have my monitor connected via DVI-D to my pc, I've calibrated it, have all the correct drivers etc, set res to 1920x1080 @ 60Hz in ATI Catalyst Control Centre (CCC) and is set the same in windows 7 display options, I have an ATI HD 4870X2 graphics card if you were wondering. Everything seems to look good, but it's just I remember on my old hdtv (only 720p/1080i, 1366x768 native), HD content looking really sharp and intense. For example the Dark Knight blue-ray was quite stunning, and casino royale too. So I was just wondering if there's something else I missing, do I need any codecs? I'm using windows 7 x64 Ultimate. Or is it something to do with compression of youtube hd content, and a lot of online hd content, like movie trailers? I mean blu-ray films are going to be huge in file size as they aren't compressed right? so is that why they look so sharp?
sorry to go on, just want to make sure I'm kind of clear with what I'm confused about.
Also this is the first time I've had my pc display connected via dvi and at this kind of resolution. my old hdtv broke and ps3 got ylod (:fp:), so i'm unable to test ps3/compare bluray on it etc.
Pretty much, YT uses it's own special adaptation of h.264 compression (a trimmed down version of the codec used by Blu Ray), but even when compared to a downloaded Blu-Ray rip the video quality on a YT 1080p clip will be nowhere near as sharp. The amount of compression used is vastily greater, as it needs to be of a bandwidth that won't kill their servers or your bandwidth. Hence 1080p YT not looking as sharp as you'd expect 1080p to.
I've got it sorted. Connected my monitor via HDMI this time, and set in the ATI CCC the res to 1080p 60Hz and video looks good now. Youtube 1080p and HD 1080P Iron Man 2 trailer I downloaded looks sweet. I'm slightly confused though, because I thought DVI (was using DVI-D) and HDMI are the same, with the only difference being that HDMI also carries audio?
