You see, in seven years the quality of LCD televisions is now light-years ahead of where it was in 2005, but by these modern standards the TCL is only barely acceptable. We found its worst weaknesses were poor black levels, lack of shadow detail, and inaccurate color. Detail levels were as good as you'd see on any TV of its price, however, and a lack of artifacts such as smearing or blockiness meant the picture was quite watchable.

Black levels: The TCL's black levels--the most important characteristic when determining what makes a "good" picture--are below par. Balancing deep blacks with full shadow detail is part of what makes a TV picture look both accurate and dynamic, and the TCL just can't do this.
After adjustment the two comparison TVs had noticeably deeper blacks. One of our test scenes for shadow detail from the recent "Star Trek" movie involves the renegade Romulan ship skulking across the screen. While not the best arbiters of shadow details, the Sony and Samsung were able to convey that there was a spaceship with lights and decks and terrifying spiny bits, while the TCL looked like someone in the distance was shining a glowworm through a cheese grater.
Color accuracy: Due to a lack of controls, we weren't able to make the colors more natural, and the secondary colors in particular stayed way outside of the normal ranges. Skies and details like the screens on the USS Enterprise looked off-color compared with the same scenes on the Sony and Samsung. A distinct lack of green in the image resulted in skin tones that were a little too rosy and skies that would look good in a catalogue but didn't resemble anything you'd see in real life.
Video processing: The video processing of the TCL was probably the most impressive thing about its performance. The TV was able to decode 1080i content without judder or moire in our sports stand test, and in our "real-world" test the TCL was the equal of the more expensive Sony and Samsung in terms of smoothness when showing the fly-by shot of the aircraft carrier. Motion resolution, on the other hand, was poor, with only 320 lines being resolved, and though this wouldn't usually be very noticeable, we did see some blurring in the faces of passersby in the closing scenes of "Mission: Impossible III."
Uniformity: Uniformity is a, and the TCL L40FHDF12TA is no different. There are some lighter patches in the upper corners and dark gray blobs in the middle of the screen, but as on similar TVs it's not usually noticeable.
Bright lighting: The TCL has a matte screen, and while this doesn't increase the illusion of contrast as on some TVs, at least it's viewable in brightly lit rooms with few reflections.
