HD PICTURE QUALITY. HD picture quality is 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). Color accuracy is excellent, so colors, especially flesh tones, look very natural and lifelike. Very good contrast—the difference between the darkest blacks and brightest whites—gives images convincing depth and dimension. Black level is 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). Image brightness is good (with the backlight control turned up), making it a suitable choice for most rooms. In scenes with subtly shaded light-to-dark areas, such as a sky during sunset, the model does a very good job producing a smooth transition without distinct, coarse bands. There is slight display non-uniformity that creates brighter cloudy areas most noticeable 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 are excellent on HD content; there is little or no trace of jaggies on the edges of objects for video and film-based 1080i video content, such as from cable.
4K UHD PICTURE QUALITY. UHD picture quality is generally excellent. All native 4K content (non HDR) we played on this model, including movies and test videos, is presented in full 4K detail with excellent fidelity when played back via the TV's HDMI input. For color, contrast and black level, the TV performs similarly to its HD picture quality.
HIGH DYNAMIC RANGE (HDR) PERFORMANCE. HDR performance is ineffective and lacks the enhancements in image quality expected from this capability. The display's lack of high peak brightness capability (by HDR standards) limits its ability to show the benefits of HDR on 4K content.
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 view the TV from the sides image quality degrades significantly. The picture shows a strong loss of color, so flesh tones look very washed out. Black levels visibly brighten, reducing contrast especially on dark scenes. When viewing the image from above or below eye level to the screen, the vertical viewing angle is good. The picture shows some change in color, contrast, and black level.
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.
SOUND QUALITY. This model's sound quality falls short with below average performance. It's acceptable for typical programming, but shortcomings become obvious with movie soundtracks and music. Bass is lacking, but treble is nicely detailed, while the overall sound is on the bright side and a bit thin and closed in. The speakers produce a good volume range so this model should play sufficiently loud in typical room environments and without obvious distortion. Also, at higher volume, dynamic compression keeps the sound from distorting but also limits the clarity of peaks in loudness, which can be a bit 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. The HD picture has noise reduction processing turned on by default, a feature we could not turn off with the supplied remote. Via a separate Roku app downloaded onto 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. The remote has a simplified design with a reduced set of buttons that support on-screen navigation. It also provides convenient direct button access to streaming services including Netflix, Hulu, Vudu, and Sling. Consider the TV's stand is 33 inches wide when choosing a table top to place it on.
INTERNET FEATURES. This TV provides Internet functionality with a selection of applications via its "Roku TV" portal with access to a library of applications. Movie streaming services that can be downloaded to this TV, or are built-in, include Netflix, YouTube, Amazon Prime Video, Hulu and HBO Now. Support for external voice assistants (not built in to the TV) include: Amazon Alexa, Google Assistant.
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.
WHAT'S INCLUDED. A quick start guide. An electronic user guide via the TV's menu. A remote control with batteries. Breakout cable adapters (one composite with stereo audio.). A detachable power cord. No printed manual is included.
