Disadvantages of LCD TV ...
Screen Refreshing RatesBecause LCDs were used for data display that did not require fast refreshing rates they did not have a fast refreshing rate. That has not changed. What it means is that fast moving objects on the screen will look awkward and mechanical since the screen cannot keep up. So the viewing experience can be significantly diminished (even to the point of unwatchable with some brands). The newest technology with name brand LCDs have typical refresh rates of 16ms or less (the lower the number the better). This means that fast moving scenes will look good and is true until you get to screen sizes over 35.
Viewing qualityLCDs were initially designed as computer monitors. As a result very few are made for video viewing. Do not buy a display with a tuner upgrade if you are planning to use it as a TV – buy it with a built in tuner. If you are using it as a TV and a computer monitor (dual purpose) buy one with a computer input rather than a display with a TV tuner. There IS a big difference.
Screen SizeBe careful about no name units when buying a display over 30. Some pictures are virtually un-viewable in fast action video.
Contrast/BrightnessMost LCD units have a difficulty going fully black because they are displaying through the lcd panel. Blacks have a tendency to be very dark grey rather than black...
Viewing AngleThough some manufacturers claim to have a viewing angle of up to 170 degrees this is NOT a realistic claim. LCDs look very good straight on but the further you get from center though you can SEE the screen you cannot make out the picture very well.
Pixel QualityPixel failure can be a real problem with many no name LCDs. Some pixel failure rates can be as high (or higher) than 10%. That means for a screen with 320000 pixels 3200 can be bad. That’s a problem
Cheaper unitsThere are alot of cheap junk LCDs units available. Cheaper units tend to have very poor picture quality and the warranties are less than acceptable.
PricingLCD TVs are quite a bit more pricey than standard TVs when it comes to big screen (35 and larger) AND the 16:9 ratios are very expensive.
