Displays Does 1080p/i HD downscale to 1050 or similar?

    I'm confused by this HD business (Isn't everyone?). I'm looking at buying a 20/21/22" monitor (I.e. 1680 x 1050) and I understand that this is NOT fully HD compliant, because it can't manage 1080p/i, only 720p. So if you buy a blu-ray/HD-DVD movie, can it play as both 1080 or 720?

    My current 17" CRT still manages 720p (1280 x 720), though. So if I was to play 1080 content on my new monitor, would it downscale nicely to fit the screen, or would it revert to a 720 version and upscale that?

    I think that makes sense. Kind of.

    Well, in general, downscaling works on ratios. So, I would find out whther they are equal ratios , which will give you the answer.

    It will be perfectly fine as the movie will just interpolate down to match the display, but your video card will have a very difficult time decoding movies at a 1080 signal, causing audio/video synchronization issues, very long command latencies (pause won't pause for at least 5 seconds), inconsistent video/audio track playback, and so on. Now, I am not completely sure, but the playback performance on your computer will probably a bit unsatisfactory.

    BTW, although you're close, my computer is still the very worse computer we have at Bit-tech... ;)

    Pfft, what you talking about? I'm rocking a gig of RAM to your two, and a 3200+ to your 4000+. I don't really care though, this computer is still as zippy as it ever was, and I don't need anything more for what I do (The hardest workout this computer gets it CS: Source). To be honest, I can't see myself getting into the HD business any time soon, but I figure a decent screen will outlive this computer anyway, so I want to make sure it's 'future proof' as much as possible.

    Anyway, back on topic, what do you mean by interpolate down? You mean a 720 video will upscale to match the res of my screen? Or that 1080 will downscale (which would be what I want).

    Yes, 720 will upscale and 1080 will downscale slightly to fit. It will be fine and you won't experience any poor interpolation (i.e.: nothing less than bicubic interpolation.) However, depending on how well your video card can decode such a wide signal (probably not good at all), you might run into a few hiccups during playback or when trying to fast-forward/rewind, etc.

    P.S.: my 9600 SE is the very worst D3D9-compatible video card in existence. Sh*t. It's less powerful than a Radeon 8500 and really craps out my system, which is otherwise exceptionally fast (kind of) for the degree of megatasking I do.

    You will not have any problems upscaling or downscaling sources. I currently run a media PC on a 1080p TV, however due to a firmware fault on the TV I have to drop the resolution a bit to 1010 lines to fit on the TV (Another story). Anyway, I use a MSI 7300GS card with HDMI and a E6300 processor with laptop hard drive and can play HD 1080p/720p movies with no problem. No pausing or noticable resolution issues)
    When using my 1050line monitor, again I can not see any resoltion issues.

    The newer cards in the world have specialist featuresets to enable faster downscaling/upscaling of HD content DarkOne - the 9800 doesn't have this because it's too old.

    Excellent, I think that's cleared things up. Thanks everyone.
