superior picture quality in all input modes The refresh rate 120Hz creates "real"moving images. July 2, 2013
Stunning HD Quality Excellent HD Quality- beautiful picture. Plenty of inputs. Good features. Better than average SD quality. Very nice looking bezel. Two downsides: Due to the reflective coating, there is an annoying reflection (along with rainbow-colored lines emanating in an x pattern from the reflection) on the screen of light sources in the room.. it can be very distracting as you can see this regardless if the tv is on or off (if your lights are high enough in the ceiling, very dim, or shine from behind the tv, this won't be an issue). Also, when displaying 1920x1080 via the VGA input, the image is skewed so you lose the right-most part of the image. Despite these two gripes, people are always wowed by the HD quality of the tv. Without the two issues (and if the SD quality was a little bit better) I would have rated this TV 5 stars. Overall a very nice tv, and a great value. October 24, 2011
Great TV! There is really nothing bad to say about this TV. I find the size to be perfect for our needs, and it functions just great! No more need be said. October 26, 2011
Excelent Picture I have had this set for a few month now and find this TV to be an excelent value for the money. Picture quqlity is excelent and can be adjusted to almost any viewers needs from sports to cinima. Sensitivity is also very good because I can use an indor antena to pick up local digital stations which was hard to do before this set. October 26, 2011
