    Detailed Test Results

    HD PICTURE QUALITY. HD picture quality was Very Good, overall. Reproduction of fine HD image detail was Excellent. Color accuracy was Very Good, with flesh tones in particular, looking natural. Very Good contrast—the difference between the darkest blacks and brightest whites—gave images convincing depth and dimension. Black levels were OK and maintained some contrast in darker scenes, but they fell short of the better TVs. The quality appeared worse as we viewed from the sides—see our Viewing Angle results, below. Image brightness was Good (with the backlight control turned up), making it a suitable choice for all but the sunniest rooms. There was slight display non-uniformity in our test sample—it appeared as brighter cloudy areas which were most noticeable on very dark scenes (or in the black bars of a letterboxed movie)—the severity can vary from model to model. Its reproduction of smooth edges on image content deinterlacing of 1080i video was Very Good (minimal "jaggies"); and film mode detection from 1080i content was Excellent.

    VIEWING ANGLE. This Toshiba model has a moderate viewing angle overall, decent, but not quite as good as the better-performing TVs we've tested. The optimal seating position for best picture quality is directly in front of this model. We examined the picture at various viewing angles, and saw the image quality was not consistent. When we viewed the TV from the sides, image quality got worse. The picture showed a moderate loss of color, so flesh tones looked a bit washed out. Black levels visibly brightened, and reduced the contrast especially on dark scenes. We viewed the image from above and below center screen, and noticed Good vertical viewing angle performance, with only slight changes in color, contrast, and black level.

    MOTION BLUR. In our motion tests, this Toshiba TV had Good motion performance, with some blurring. It does not have a special feature to minimize motion blur.

    SOUND QUALITY. We got Good sound quality, about average among the models we've tested. When watching a blockbuster movie, a concert, or TV show, it can deliver decent performance but just not like the better performers. In our listening evaluations, we found the bass (low frequencies) was moderately deep and provided some sense of fullness but lacked definition. Treble (high frequencies) was satisfactory. The overall sound was closed in. This TV should be OK if the room isn't too noisy—we found the speakers could produce a Good volume level, but quality did degrade at the highest settings. Also, at higher volume, its dynamic-compression feature prevented gross distortion, but noticeably limited the clarity and naturalness of loud peaks. Overall, though imperfect, most people would find this sound quality acceptable.

    EASE OF USE. Consider the TV's stand is 36 inches wide when choosing a table top to place it on. On first power up, an on-screen guide appeared—which you could choose to follow when setting up the TV. The remote controls the TV via an RF signal and doesn't need to be pointed at the TV. It has a simplified design with a reduced set of buttons. It includes many of the typical buttons: power, channel up/down, volume control, mute, menu, and exit. But annoyingly it lacks a source input button. The remote has a microphone for accessing a built-in voice assistant feature. It also has dedicated buttons for streaming Prime Video, Netflix, HBO, and Hulu.

    INTERNET FEATURES. This TV provides internet functionality via its "Fire OS" 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, Disney, Apple TV and HBO Max. Includes built-in Alexa, a virtual assistant, which allows you to use natural speech to ask questions, launch applications, and search programming by talking to the remote.

    CONNECTIONS. This model has three HDMI inputs (one supports ARC, audio return channel). It also has one USB port, an optical digital audio out, a headphone out, an Ethernet port, WiFi wireless networking; Casting, which allows you to send streaming content from your mobile device to the TV via your home network.

    WHAT'S INCLUDED. You get with this TV: a quick start guide, an electronic user guide via the TV's menu, a remote control with batteries, and a detachable power cord. No printed manual is included.
