Rated 4 out of 5 by 3 reviewers.
Rated 5 out of 5 by Nice Picture We bought this tv for my 83 year old mother as a birthday present. She claimed that she didn't need or want a large screen tv. Needless to say she loves it. She is able to operate all of the controls and now couldn't live without it. We her children were very pleased with the price and the quality. November 24, 2014
Rated 3 out of 5 by Head phones Cannot connect head phones to this model. This was a hugh disappointment since I was assured that I would not have a problem. July 24, 2014
Rated 4 out of 5 by I love my dumb tv. Primary use: movie and television shows over media streamer (WDTV Live Plus HD) Test Material: The Croods, Gurren Lagann, Frozen, From Up on Poppy Hill, Pacific Rim Calibration Method: THX tune-up (Android), Custom picture setting Construction / Connectivity: 4/5 This tv is very light and pretty thin. The bezel is fairly narrow, making sure you get some nice real estate out of your screen. The connections are flush with the back panel, so be aware of that fact when using wall mounts. Ninety-degree HDMI cables are recommended in that situation. Also of note on connectivity is that there's little of it. There's one component, two HDMI, one USB, and a coax input. That's it. However, for most people that will be enough if you use the component for your cable box, one HDMI for a game console, and the other for a blu-ray player / streamer. Just be aware of that fact if you need more than that. Setup: 5/5 The included stand was very intuitive and simple to install. Two small brackets slide into place on the stand, are screwed down, then the whole assembly slides into place in the back of the set. I suggest laying the panel face down on the edge of a table cushioned by a soft, non-abrasive surface such as soft towels or bedding. The stand is secure and the entire bottom frame is rubberized to make sure it stays put. Since I don't use cable tv or antenna, the initial setup was over in a matter of seconds. Video: 4/5 Viewing movies over the streamer gave a clear, bright picture. After calibration, the color was vivid, if just a hair over-saturated. Contrast was also good, with bright scenes in The Croods displayed in detail. Brightness (dark detail) was also good, though there was a little backlight bleed-through, which is common of LED-LCDs. A viewing of Gurren Lagann tested its ability for motion, which has frantic action sequences. The set barely skipped a beat, following the action without noticeable blurring / judder. From Up On Poppy Hill showed something a little different. Studio Ghibli films aren't known for the smoothness of their animation, and the set actually makes it more noticeable. In a direct comparison, the animation in Disney's Frozen is much smoother, and the set has no trouble keeping up. Audio: N/A (I used external speakers) Settings / Remote: 4/5 For a basic set, the picture controls are actually pretty good. There are separate controls for Backlight and Contrast (not common of low-tier LCD's), along with the usual Brightness, Color, Tint, and Sharpness controls. Some other controls usually found on higher tier sets are the Aspect control (specifically HD sizes), two noise reduction settings (MPEG and Video), and Black Level (which is consists of two settings: Light and Dark. It instantly makes the panel lighter or darker, which is nice for night time viewing so you don't strain your eyes.) Worthy of note is the A.I. picture control. This feature actually created a noticeable flicker where there is a mixture of light and dark elements. This was especially evident in The Croods, where Grug's entire fur coat flickered. I turned the setting off. After which, the flicker disappeared. The remote is how you might expect it; however the Menu button is just below the Power button, which had me accidentally turning the tv off when I wanted to adjust a setting a couple of times. Features: 3/5 As this is a "dumb" tv, there is no internet connectivity or apps such as Netflix. This posed no issue for me as I already have a streamer. Other common devices such as video games consoles and blu-ray players contain these features anyway. There's also an included Media Player if you connect a flash drive via the USB port. Pretty nifty, as it can show video, play music, and pictures; but again, because I was already using a streamer, this feature was unnecessary. Conclusion: If you already have some kind of external device to watch internet content on, this tv is great. I was initially worried about the fact that this is a 60Hz, bottom-of-the-line set, but those concerns were quickly dispelled after watching it in action. Colors are good, contrast and brightness are good (not great because of backlight bleed-through), blur and judder are minimal (with the A.I. turned off). I wish all manufacturers treated their lowest tier sets this good. March 23, 2014
