This is my second Samsung TV and I am very happy with this purchase. Sure its a pricey TV but its also loaded with great features, tons of settings, and the latest LED backlight technology which provides black level that takes LCDs into Plasma territory without the power demands or heat of plasma. This new 55 inch takes less power than my old 40 inch LCD panel due to the smart backlight which turns down (or off) LEDs in dark areas of the displayed image.
Overall I think its picture quality is up there with the high end Sony (LDC) and Pineer (plasma) displays. Samsung has really made a name for themselves in the last few years with there continually improving line of LCDs. I really like how each input saves its own settings so you don't have to adjust whenever you switch inputs.
For gaming: Like other LCDs, in its default configuration there can be some trouble with some games with latency and image blur. I had one major issue with Rock Band when the animation behind the scrolling notes made the notes blur. You can use "E-Mode Game" to fix this but I found a better solution. Because you can not change the brightness/contrast or backlight with "E-Mode Game", I used HDMI2 input for the Xbox 360 and changed the label on HDMI2 to "PC". This tells the TV that you have a PC hooked up to HDMI2 and skips some of the color and image processing just like the "E-Mode Game" but you can now control brightness/contrast and backlight. This only works on HDMI2 and its briefly mentioned in the manual but it makes a much better low latency game mode than the "E-Mode Game" that Samsung provides.
For Movies: Much better than any other LCD due to the great black levels. Deep blacks and good dark detail can be seen with this TV with the right settings. With LED backlight and a Blu Ray player, blacks are actual black instead of dark gray and the black bars on widescreen movies disappear from view. And because its and LCD, bright seens have much more punch than even the best plasma displays.
For TV: If its standard definition don't expect too be impressed. I think the scaler and standard def TV feed looks good for what it is and you can use the LOW setting of dynamic contrast and auto motion plus to make it palatable. But if you have HD TV it should look great on this TV.
Negatives: There is only one real negative to this TV but for me its a very, very minor one. When viewed from an angle, you will loose the inky blacks even from just 30 degrees off axis. Its not a big deal for me for two reasons. The couch is directly on-axis and it looks great from any seat on the couch. From the side chair (about 40 deg) it still looks great and you would probably not even notice you were losing some black level until you move to the couch. Off axis, this TV still looks as good as any high end LCD I have seen. So if you will often need to watch off axis, you do lose some of the benefits of the LED backlight and maybe you should go for a plasma because all LCDs have this issue and most have it much worse than this TV. I just think its noticed more because the on axis blacks are so good. That is why it is often mentioned in reviews. Then only other minor issue is that the stand does not swivel. That would have been a nice touch but with a TV of this size, I probably would not move it much.
For Geeks: This TV is great. The number of different settings you have to play with are unbelievable. You can even do both color balance and grayscale calibration with this TV without needed to go into the services menu. You are provided with full grayscale setting (RGB Gain and Cut) and Color (RGB and YCM) from the standard settings. I really like this because I can try to calibrate it myself without the worry of messing up the service menu settings.
So, you pay a lot for this TV but I think its worth it for the picture quality and a chance to check out LED backlight technology before all the other LCDs get it, and they will! I think LED backlighting is a breakthrough for flat panels and will continue to improve over the next few years and become standard for LCD. So, I just paid a premium to see it now.Buy Samsung LN55A950 55" 1080p LCD HDTV with 120Hz refresh rate and LED backlighting!
