HD PICTURE QUALITY. HD picture quality was only decent. Picture detail was compromised due to aggressive noise reduction processing which wiped out image texture and also created some trailing echoes on people and objects in motion. We would hope that a firmware update could remove this issue. Color accuracy was very good, with flesh tones in particular, looking natural. Contrast--the difference between the darkest blacks and brightest whites--was good, so images had depth and dimension, typical of most models we test. The brightness level was good, making it a suitable choice for most rooms. Black level was generally good, though not as dark as better performers on the darkest scenes (though quality does degrade as you move to the sides - see viewing angle). In scenes with subtly shaded light-to-dark areas, such as a sky during sunset, the model did a very good job producing a smooth transition without distinct, coarse bands. There was notable display non-uniformity that created brighter cloudy areas, most visible on very dark scenes (or in the black bars of a letterboxed movie). We routinely see this issue with LCDs and severity can vary from model to model. The deinterlacing and film mode operations were excellent on HD content; there was little or no trace of jaggies on the edges of objects for video and film-based 1080i video content, such as from cable.
VIEWING ANGLE. This TCL has a narrow viewing angle overall, below-average performance among TVs for this attribute. Only those seated directly in front of the screen will see the best picture quality. When we viewed the TV from the sides image quality degraded significantly. The picture showed a moderate loss of color, so flesh tones looked a bit washed out, along with a moderate color shift. Black levels visibly brightened, reducing contrast especially on dark scenes. When viewing the image from above or below eye level to the screen, the vertical viewing angle was very good. The picture showed minimal change in color, contrast, and black level.
ULTRA HD PERFORMANCE. Overall UHD performance was very good and showed very good HD-to-UHD upconversion. All native 4K content (non HDR) we played on this model, including movies and test videos, showed generally very good detail when played back via the TV's HDMI input, but fell short of the better performers. This TV can stream 4K programs from Netflix and YouTube. Images were clean and finely detailed. High-resolution photos were displayed in full 4K detail. With regular HD content, the TV's HD-to-UHD up-conversion processing was very good, with edges along diagonals of image content showing slight jaggies, just short of the best we've seen.
HIGH DYNAMIC RANGE (HDR) PERFORMANCE. HDR performance had very limited effectiveness. The display's lack of high brightness capability (by HDR standards) limited its ability to show the benefits of HDR to full effect on our test videos, while revealing little contrast between moderately bright and very bright highlights within a scene. It did a good job reproducing a greater range of nuanced shadow detail from black to white, with no obvious banding on areas of the image that have subtle shade variations. There was no visible loss of near-white shadow detail in the brightest areas. Very bright, colored objects remained nicely saturated, and an extended range of color capability was only slightly apparent from our test patterns. This TV supports both HDR10 and Dolby Vision, HDR formats.
MOTION BLUR. This TCL TV has good motion performance, with some blurring on our motion tests. This model does not include a blur reduction feature.
SCREEN REFLECTIVITY. Though not as mirror-like as on some models, this screen surface is glossy and therefore susceptible to reflections from a nearby lamp or window. It does a good job reducing glare from ambient light and maintains contrast in a brighter room environment.
SOUND QUALITY. This model has fair sound quality with below average performance. It's acceptable for typical programming, but shortcomings become obvious with movie soundtracks and music. Bass was lacking, but treble was nicely detailed, while the overall sound was a bit thin and closed in. The speakers produced a good volume range so this model should play sufficiently loud in typical room environments and without obvious distortion. If sound quality matters to you, you might want to add a soundbar or other external speaker system.
EASE OF USE. On first power up there is an on-screen guide that helps you through setting up the TV. TCL provides a small, basic remote with a reduced set of buttons that support onscreen navigation. It does not include a number pad, but does provide direct button access to Netflix, Sling, Hulu, and STARZ streaming services.
INTERNET FEATURES. This TV provides advanced Internet capabilities via its "Roku TV" portal with access to a library of applications. Movie streaming services include Netflix, YouTube, Amazon Prime Video, Hulu, HBO Go and HBO Now.
CONNECTIONS. This model has three HDMI inputs-- one supports ARC (Audio Return Channel), one composite input, and no component input. It also has one USB port, an optical digital audio out, a headphone out, an Ethernet port, WiFi wireless networking; DLNA, to access files within your home network; Casting, which allows you to send streaming content from your mobile device to the TV via your home network; Screen mirroring, where the image on your smartphone or other compatible device can also appear on the TV. Analog connections are made via a special breakout cable adapter (included) that attaches to the TV as a single plug. That means you plug your component, composite, or stereo cables into a dangling "pigtail" rather than the back of the TV itself. This is actually a more convenient way to make the connections on slim-profile models, but if you lose that adapter you'll have no way to connect your cables directly to the TV. The cable connections on the rear panel are recessed with side or bottom-facing ports, so wires don't protrude beyond the display's depth.
INCLUDED IN THE BOX. A quick start guide. A remote control with batteries. Breakout cable adapters (one composite with stereo audio.). No printed manual is included.
ABOUT ULTRA HD TESTING: We test UHD picture quality using 4K movies, videos, photos, and test patterns to confirm these displays deliver performance to this format's full potential. We check the TV's ability to reproduce 4K image detail, as well as high dynamic range (HDR) for TVs that support this capability. Image quality is tested using a 4K movie player connected to the TV's HDMI input, as well as from files stored on flash drive plugged into the TV's USB port. We also check the quality of 4K streaming from Netflix or YouTube (if the service is supported by the TV), and how well the TV can upscale HD movies to the display's higher UHD resolution while keeping artifacts such as "jaggies" along the edges of image content to a minimum. The best UHD TVs, and HDTVs, present high fidelity images that reveal the full quality of the best source content without degradation.
