Quality of video on 27" iMac?

    Love the idea of the big screen, but I'm wondering if the massive bump in resolution will completely spoil lower quality video files, and whether or not I'll be able to really use all that space for full screen video without massive degradation in picture quality. I'm planning to use the iMac as a second TV, and when I bought my HDTV one of my main concerns was its ability to upscale SD content. It can satisfactorily display pretty much anything I throw at it, while many of my friends' TVs display lower quality SD material as an unwatchable mess. The iMac should be able to handle far more complex upscaling algorithms, but does Snow Leopard actually provide upscaling out of the box when I stretch a video I'm watching in VLC? If so, how well does the 27" screen upscale low-res content? Do YouTube videos or low quality video files become unwatchable on a screen with such high resolution? Do they look significantly worse than they would on, say, the 1280x800 screen I'm using now? I don't want to be forced to watch sub-HD content in a tiny little window relative to the size of the screen if I can help it.

    Might I be better off with a 21.5" iMac with lower resolution, which ought to be slightly more forgiving with full screen SD content? I know there are plenty of uses for the 27" screen beyond video playback, and I'm not knocking the machine at all. Just trying to buy something that will best serve my own specific needs.

    The video quality really blew me away, I haven't been able to watch anything in HD yet, just fairly poor quality TV downloads which look pretty damn good. If you sit close to the screen you can see the poor quality but from a short distance you really can't see. These videos look better quality than they did on my 24" windows PC, the colours are amazing.

    I don't know about upscaling but this video for example: http://www.youtube.com/watch?v=Qr31Vhu01fc
    looks as good as it does quality wise on my 22" 720p HDTV on the music cable channels (not broadcast in HD).

    In fact I'll see if I can show you... http://www.youtube.com/watch?v=Oka_6YqVzts didn;t really come out very well but hopefully you get what I'm trying to say.

    Fantastic! This is exactly what I needed to know. There's no longer any doubt in my mind that the 27" screen is for me. And thanks for uploading the video - it gives me a decent idea of how real world video playback actually looks, and I don't think it'll be an issue at all. Awesome :cool:
