    i was thinkin of getting an imac this weekend and was wondering if theres a difference in screen quality other than the size between the 20inch and the 24 inch?
    i checked the tech specs and it seems the 24inch ones are alot brighter. so i cant seem to decide.
    the 24inch ones seem super big.

    yes, the 24" has a "better screen" ... i forget the type of panel but it is the good one.

    and the 20" uses the more standard thiner TN panel... however the 24"ers are plagued with uneven lighting

    either way you look at them the iMacs are kinda crappy right now, you might want to wait for next revision, or maybe pick up a mini with a 23" ACD

    actually i do have a 20inch cinema display now with my macbook pro, so i was thinking of upgrading to a imac.
    so theres definitely a noticeably difference between the cinema displays and the imacs then?

    Well, I wouldn't say "crappy". They work well and do the job. I have edited several HD video projects on my 20" iMac and it did fine.

    You won't notice unless you look for problems. Let's just put it that way. The "gradient" can only be seen on a black screen and has more to do with the glass diffusing light than much of anything else. For a vast majority of things the 20" is fine. I probably should have gone for the 24" because I would have wanted a little bit larger screen, but other than that I don't think it makes much of a difference. (I did save $300)

    Earlier today was the first time I noticed the yellowing, but that says something since I've had it since August. I had noticed the vertical brightness change when I move my head above the screen but it's not that huge a deal for me. Seems to me that they both have the issue.

    This isn't exactly true! It's seen on a white screen (I've got a 24"). Regardless, I'm still convinced that the 24" is better than the 20 even with the uneven lighting.

    Actually it's a bit of a lottery out there when it comes to 24" iMac screens. Some seem to be fine, some have slight gradients which aren't really an issue and with a bit of calibration will work fine, but others have very clear gradients and should be avoided at all costs. Many also have very bad backlight bleeding problems which are very noticeable when watching DVDs.

    Since the iMac is due for an upgrade within the next month or two then I would wait until the new models are released.

    If your ACD is a current version it has an S-IPS (true 8-bit) panel, just like the 24" iMac. The 20" has a TN (6-bit) panel.

    You know what?

    After reading all the threads about screen display quality and such I have come to the following conclusion.

    NEVER make an opinion about a screen display using solely information provided by others. Use YOUR eyes, go look at what you are considering purchasing. Make your decision based on your own observations.

    Some will tell you the 20" is great. ( they probably own 20" units )
    Some will tell you the 20" bad. ( they probably own 24" units )

    Go out and test drive a 20" iMac, look at it from all angles you might expect to use it from. If you are gonna use it standing on your head, with your feet hanging out the window ... test it like that.

    Don't " refuse to buy it " because someone says .... " the ____ sized screen looked bad when standing on my head with my feet hanging out the window " if that is not how you plan on using it.

    Personally I own a 24" iMac. When I went to buy it I looked at the 20" units though I knew I wouldn't buy one. My reason for not buying? I just sold a Power Mac and 22" LCD display, I did not want a smaller screen so the 24" was for me.

    I purchased a 24" 2.8 in December and then went back in February and purchased a 24"2.4 for my son. When we purchased the 2.4 we were looking at the cheaper 20" but could tell a huge difference in the store between the two displays. I asked the sales person at the Apple Store if there were different displays in the two and he didn't have a clue nor did the senior sales person. I asked why the one looked dimmer than the other and was told that one had a different lighting above it. So I could tell real fast that they were too stupid to lend any help so we asked if we could move the 20" next to the 24" and then you could see how great the 24' screen was. The sales person just acted dumb founded.

    This is great advice. I agree. Bad to one person is fine to someone else. That said, the 20" screens are crap. :D

    Well if the salesperson was a smart salesman he would have recommended the 24 inch anyway, even if the screens had the same specs/quality.
