HD PICTURE QUALITY. HD picture quality was excellent. Though we ultimately got the picture to display excellent HD detail, adjusting the picture settings was not a straightforward process (see ease of use). After adjustment, image detail was a bit over-sharpened and we could not minimize this in the picture settings. Color accuracy was excellent, so colors, especially flesh tones, looked very natural and lifelike. Contrast--the difference between the darkest blacks and brightest whites--was good, so images had depth and dimension. 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). The picture could be driven to a fairly high brightness level with the backlight turned up, so the picture is well suited for a very sunny room. A lower backlight setting is recommended for a dimmer viewing environment. 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. 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 strong loss of color, so flesh tones looked very washed out. 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 good. The picture showed some change in color, contrast, and black level.
ULTRA HD PERFORMANCE. Overall UHD performance is very good but HD-to-UHD upconversion falls short. All native 4K content (non HDR) we played on this model, including movies and test videos, was presented in full 4K detail with excellent fidelity when played back via the TV's HDMI input. Via the USB port, high-resolution photos were displayed in full 4K detail. With regular HD content, the TV's HD-to-UHD up-conversion processing fell short, revealing some visible jaggies along the edges of diagonals when playing HD content.
HIGH DYNAMIC RANGE (HDR) PERFORMANCE. HDR performance is not effective. The display's lack of high peak brightness capability (by HDR standards) limited its ability to show the benefits of HDR to full effect on our test videos, while revealing little or no 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. Brighter colored objects remained nicely saturated.
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, as was treble detail, while the overall sound was closed in. The speakers produced a good volume range so this model should play sufficiently loud in typical room environments, but quality does degrade at high volume settings. Also, at higher volume, dynamic compression kept the sound from distorting, but also limited the clarity of peaks in loudness, which can be distracting on some audio content. If sound quality matters to you, you might want to add a soundbar or other external speaker system.
EASE OF USE. Access to certain picture settings requires that you download the Roku app onto a mobile device. The HD picture has aggressive noise reduction processing turned ON by default (UHD picture was fine), a feature we could not access in the settings menu with the supplied remote. However, via a Roku app downloaded to your personal mobile device you can adjust both the noise reduction and gamma settings. Noise reduction should be set to OFF by default. On first power up there is an on-screen guide that helps you through setting up the TV. TCL provides a small, advanced Roku remote with a built-in microphone and a reduced set of buttons that support onscreen menu navigation. It does not include a number pad but does provide direct button access to Netflix, Sling, Hulu, and DirecTV NOW streaming services. The TV's stand is 27 inches wide.
INTERNET FEATURES. This TV provides basic Internet functionality with a limited selection of applications 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.
INCLUDED IN THE BOX. A quick start guide. A remote control with batteries. Breakout cable adapters (one composite with stereo audio.). A detachable power cord. 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 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.
