    HD picture quality

    Evaluated using basic HD content (non-HDR). Based on objective tests and subjective evaluations by expert testers after TV is adjusted using standard picture controls to achieve the highest-fidelity image possible. Tested image attributes include detail, color accuracy, and contrast, using videos from a Blu-ray player, cable box, and professional broadcast equipment. All video content is played through the TV's HDMI inputs. Some tests are also performed via the TV USB input.

    UHD picture quality

    Evaluated using basic, non-HDR, 4K-UHD content. (HDR content is tested separately) Based on objective tests and subjective evaluations by expert testers after TV is adjusted using standard picture controls to achieve the highest-fidelity image possible. Tested image attributes include detail, color accuracy, and contrast, using signals from a Blu-ray player, cable box, and professional broadcast equipment. All video content is played through the TV's HDMI inputs. Some tests are also performed via the TV USB input.

    HDR

    HDR

    HDR (High Dynamic Range) indicates how effectively the TV can reproduce the enhanced quality of HDR content. The benefits of HDR are best revealed on a display with a high peak brightness capability which allows them to present images with more realistic lighting and highlights. Very effective HDR can also reproduce fine gradations of shadow detail from black to white, and display a wider range of colors. Ineffective HDR presents images that are no better than regular standard dynamic range (SDR) TVs.

    Motion blur

    Evaluation of how well the display can present a blur-free image during motion scenes. If the TV's blur reduction feature also invokes a "smooth motion" effect, the feature will be turned off for our test.

    Sound quality

    Evaluated from the set's built-in speakers with subjective testing by a listening panel, and support from audio test equipment. In our judgments we listen for overall clarity of sound, depth of bass, effective volume level, and audible distortion, from dialog, music, and movie soundtrack content.

    Ultra HD Picture Quality

    The Ultra HD picture quality rating represents a composite of observations relating to this TV's ability to reproduce full UHD image detail when presented with 4K content, and how well it upconverts HD source material to the TV's higher native UHD resolution. We also inspect 4K photo quality and 4K video support when content is played via a USB flash drive.

    Detailed Test Results

    PICTURE QUALITY This model had very good high-definition picture quality and did an excellent job displaying the finest detail. Color accuracy was very good, with images looking quite natural. Contrast--the difference between the darkest blacks and brightest whites--was good, so images showed some depth and dimension. In this respect, the TV was similar to most of the models we test. The brightness level was good, making it a suitable choice for most rooms. In scenes with subtly shaded light-to-dark areas, such as a sky during sunset, the TV 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 Panasonic has a narrow viewing angle overall, below-average performance among LCD sets on this attribute. Only those seated directly in front of the screen will see the best picture quality. If your family is seated in chairs off to the sides of the TV, they will see increasing degradation of image quality the farther they sit from center.

    When we moved off to the sides the horizontal viewing angle was fair; the picture showed a strong loss of color so flesh tones looked very washed out. Black levels brightened significantly, making dark scenes look hazy. 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.

    MOTION BLUR This Panasonic TV has only fair motion performance, with significant blurring on our motion tests. Though it claims to have a higher frame rate than 60Hz, a feature designed to reduce motion blur, it could not be found in the menu, and performance was worse than on models with an effective similar feature. On typical program content, the blurring effect is often fleeting and may not bother most people. However, keen-eyed viewers may detect the loss of texture and detail on scenes with movement, especially in high-quality video such as a Blu-ray movie.

    SCREEN REFLECTIVITY Though not as mirror-like as on some LCDs, this screen surface is glossy and therefore susceptible to reflections from a nearby lamp or window. The screen is dark so it does a good job reducing glare from ambient light and maintains contrast even in a bright room.

    SOUND QUALITY This TV's sound is only fair, acceptable for typical programming but shortcomings become obvious with movie soundtracks and music. It has a good volume range. At more typical listening volume levels the TV has a generally smooth sound though bass and impact are only decent, and the highs are rolled off. If sound quality matters to you, you might want to add a soundbar or other external speaker system to this set.

    EASE OF USE Overall, we found the set easy to use. Setting up the TV for the first time was fairly straightforward, as was access to features and controls you'll probably adjust only once. Ease of access to features you typically use more often was excellent. Also, the remote is very good, and the on-screen menu is easy to navigate.

    The black against black labeling of the connectors on the TV console is very difficult to read. The remote's major function buttons were sufficiently large and have high-contrast labeling, making them easier to see and navigate.

    STAND ASSEMBLY Mounting the TV to the included support stand is fairly straightforward. The stand requires the assembly of a few parts before mounting.

    INTERNET FEATURES This TV does not have access to the Internet.

    CONNECTIONS This TV includes two HDMI inputs, one shared connection between the component and composite inputs (which means you can only use one type or the other at a time), optical digital audio out, and one USB port. This TV has no type of wireless connectivity. HDMI and analog cable connections made to the rear-facing panel will protrude beyond the panel's slim depth.

    INCLUDED IN THE BOX The TV comes with: a printed user manual, an electronic manual in the TV's menu, a quick start guide, and a remote with batteries. ABOUT FIRMWARE VERSION: Our test results and picture settings are valid for the version of firmware indicated. If your TV's firmware differs from the one shown you either have an older or a newer version of firmware. Manufacturers may periodically upgrade the TV's firmware to enhance operation, fix bugs, or add features. Firmware upgrades may be downloadable directly to your TV via a wired or wireless network (if internet capable), USB port, or memory card, depending on your TV's capability. You can check your TV's firmware version, or upgrade to the latest firmware by pressing the menu button on your remote and navigating to the appropriate submenu, typically under settings. Consult the user manual or manufacturer's website if further guidance is needed.
