Be sure to take some DVDs of your own to help judge picture quality. Include something with fast-moving real-life scenes (to check for picture smearing and judder), and something with very dark scenes (to see how well blacks and colour gradations are rendered). The staff should be happy to let you view your own DVDs on the models you're interested in.

If you are going to any shop that isn't a dedicated AV pro equipment shop, so in the UK seven oaks hifi, etc. Then the TVs will be set up incorrectly, the staff will know less than nothing about the equipment. The shops will more often than not have lighting which is entirely different to that which is in a living room, or any room where a TV would be situated. The best way to decide is to look at internet reviews, find a friend who has the same TV, or look at internet forums (like AVforums.com).
Also burn in on more recent TVs, say post 07, has drastically reduced, thus making it an almost irrelevant argument against them. One advantage that Plasma has is the strength of colour and black replication. I personally adore Sony TVs so would tend towards those, avoid Grundig, Samsung make good screens, but I wouldn't be happy with the sound they produce. So for me,I would go for either the Sony or the Panasonic.
If you do go for the Plasma, always heed these instructions:
Quote:
(1) Some obvious advice: Do not leave static images on your plasma TV screen for more than an hour. Turn off your unit when you are not watching it. Do not pause DVDs for more than 20 minutes at a time.
(2) Know that plasma screens are more prone to burn-in during their first 200 hours of use. When phosphors are fresh, they burn more intensely as they are ignited. This means that relatively new plasma display TVs are prone to "ghosting", which occurs when on-screen images appear to stay on the screen belatedly. This is a function of the high intensity with which new phosphors "pop," and this phenomenon usually "washes out" on its own, as the screen displays subsequent images. Displaying a bright, or moving snow image (as with a DVD or VCR with no input) will "wash" a ghost image from the screen in most cases. Many plasma manufacturers have installed anti-burn settings, which are monotone gray or snow screen settings which recalibrate pixel intensity levels uniformly - thus eliminating any image retention (ghosting). It is a good idea to run this type of program after the first 100 hours or so.
(3) Adjust the CONTRAST setting at or below 50% on your new plasma TV. These days most plasma TVs are preset to either peak or very high contrast (also called picture setting on many TVs). This forces phosphors to glow more intensely, which decreases the length of time necessary for burn-in to occur. Our advice is to reduce the contrast setting to 50% or less for the first 200 hours of use. And, be sure to avail yourself of your plasma's anti-burn-in features.
(4) Some plasma televisions burn-in more easily than others. In my experience, AliS type panels -- the ones utilized by Hitachi and Fujistu -- seem more readily given over to problems with burn-in. As well, be more wary of the 2nd and 3rd tier brands as their technology is usually not as up to date as some of the better 1st tier brands.
(5) When displaying video games and other content which have static images, use your burn-in protection features like power management settings, full-time picture shift (both vertical and horizontal), and automatic screen-saver functions. Check your Owner's Manual for further information.
(6) Realize that quality matters with burn-in as with everything else. Purchase a plasma display that has really good scaling, so that you can watch 4:3 TV programs in widescreen comfortably. It is better not to display black bars on your TV screen for prolonged periods of time (especially in the first 200 hours), so you are probably better off watching most everything in "full screen" mode. This should not be much of a problem todays selection of widescreen HDTV and DVDT content.
