There appears to be a lot of confusion over the new so called "LED TVs" made by Samsung and others. First of all, these are NOT really LED TVs! They really are standard LCD (Liquid Crystal Display) TVs but they use LEDs (Light Emitting Diodes) to back light the LCD screen. Up until now, most LCD TVs use Cold Cathode Fluorescent Lamps (CCFLs) to back light the LCD screen. There are many potential problems with CCFLs with the biggest ones being Black Levels and Power Consumption. Since you can't really dim a CCFL, you never get very good black levels so dark scenes tend to lack detail. Manufacturers have learned some tricks to make this better over the years, but LCD is still lacking as compared to Plasma Displays. So LCD TVs that use LEDs use less power and have the POTENTIAL to have better black levels since LEDs can be dimmed or turned off very quickly. But as always, make sure you view any TV before you buy it to verify the picture quality. So why wouldn't you buy an LED  backlit LCD TV? They are thinner, use less power and have better black levels.. Well they are much more expensive than a standard LCD TV so you have to decide if it is worth the extra money. Of course over time, as the volume goes up and competition increases, prices will come down on these models. Comments?

ADI has ISF certified technicians that can come to your home and calibrate your TV to industry standards. But is it worth the time and money? The answer may depend on what you are used to seeing. TV manufacturers have purposely miss adjusted their displays for years so that they are too bright and the colors too "hot". Of course this is to catch your eye when you go to your favorite store to buy a new TV. But if you are used to seeing TVs this way, and have for years, then is this the new "standard"? Video Calibration will absolutely make your TV look more natural and realistic. But does that make it right? The reason I bring this up is that a small percentage of our customers (less than 2%) actually liked the picture better before we did the calibration! In those cases we have gladly refunded their money and set it back to factory defaults. So my point is that some customers have become used to seeing TVs with incorrect settings and they like it that way! Comments?
