Is it normal? (my LCD 1080p problem)

i got a 1080p LCD about 20 days ago, and when i first started using it for games i really enjoyed it, most all of my games are mostly bright colors... however the more i use it the more i run into dark colors, and with this i get this kind of nasty blue color and a grainy look. firstly i thought it was just playing DVD's (the first time that i noticed it that i really thought it looked like shit) but now that ive got planet earth on Blu-Ray im starting to think that maybe there is something wrong, because when there is a dark part of the screen its most often this blue color that is all splotchy, i know that LCD's don't have absolute black, but this is kind of crazy, and it doesn't happen in the black parts on the sides when watching TV/DVD's in square resolutions. the other thing im noticing that might be related is that when it fades to black a faint image of whatever was on the screen stays, and it normally stays until another image pops on the screen, then it seems to refresh and go back to being solid black.

is this ghosting? if so is the TV a dud, or is this just a downside to LCD's?

(i dont notice this on my monitor/or my old 32in TV which was 720p)

    What you're describing isn't ghosting. It could be de-interlacing artifacts, which typically present themselves as pixelated noise in black colors while in motion.

    The other issue definitely sounds like image retention, which is usually associated in plasmas, but while annoying, is probably considered normal.

    In general what you're describing is not unique to LCDs, but rather the parts involved in individual television models. Some do what you describe, some do it more or less, and others, not at all.

    Who is the manufacturer?

    its westinghouse, ive had a set of thiers in the past (a 32in 720p LCD) and i never had a problem with it, which is why i went for this one.

    thanks for all the info, i think im going to bring it back tomorrrow and go and buy a Phillips for a little more $, and see how that turns out... ive seen screens this size before and never noticed this, so it was a real disapointment.

    Westinghouse is hardly a bad brand; what model is this? I'm using an L2410nm for tv/dvd/pc and not noticing this kind of problem.

    Write down the model number of tvs you are interested in buying and browse a bit online for reviews. You can often find a professional review on cnet. Otherwise I look at user reviews and try to find a well written review that mentions problems with the set. I don't trust most positive user reviews because they may have been written by someone who isn't very critcal and is just happy to just have bought one of them shiny HDTVs everybody's talking about.


    As for your specific problems, it might be the model you bought. I know I've seen mentions of such problems while browsing reviews before purchasing my HDTV. Some TVs have a blueish tint in their black (mine does a bit, but it's barely noticeable). And I've also read about sets that get those artifact "clouds" in their dark colors. Dunno about your images that stick on the screen though.

    If it's 1080p that means it displays 1080p. otherwise they can't call it 1080p. Now, often 1080p sets will only display up to 1080i via component outputs, and HD broadcast TV is 1080i so it may have simply been specifying that it displays 1080i w/ no problems.

    was checking around and they must have thought it only accepted 1080p signals (some 1080i TV's apparently came with HDMI)
