HD PICTURE QUALITY. HD picture quality was Very Good, overall. Reproduction of fine HD image detail was Excellent. Color accuracy was Excellent, so colors, especially flesh tones, look very natural and lifelike. 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, making it a suitable choice for all but the sunniest rooms. Its reproduction of smooth edges on image content for "up-converted" HD-to-UHD images fell short with some visible "jaggies" (jagged edges); deinterlacing of 1080i video was Excellent; and film mode detection from 1080i content was Excellent.
4K UHD PICTURE QUALITY. Overall 4K UHD picture quality was Very Good, overall. In our UHD testing, we played native-4K movies and test videos (non HDR) thru the TV's HDMI input, and found their image detail was all there. For color, contrast and black level, the TV performed similarly to its HD picture quality.
HIGH DYNAMIC RANGE (HDR) PERFORMANCE. HDR performance was ineffective. In our tests, the display did not have the peak brightness capability necessary (by HDR standards) to reproduce the extended contrast on our HDR content. It could not reveal much contrast between the moderately bright and very bright highlights, while the brightness levels in the mid-to-lower tones, like those in an indoor scene, were preserved.
VIEWING ANGLE. This Insignia has a narrow viewing angle overall, below-average performance among TVs. Only those seated directly in front of the screen will see the best picture quality. We examined the image quality at various viewing angles—its image quality notably decreased as we moved away from the center position. 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, 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 Insignia 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) to be adequate but lacking a sense of fullness and lacked some definition. Treble (high frequencies) was satisfactory. The overall sound was closed in. This TV should be OK in rooms large or small, noisy or quiet—we found the speakers could play at a fairly loud volume level and without obvious distortion. Overall, though imperfect, most people would find this sound quality acceptable.
EASE OF USE. Consider the TV's stand is 39 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, volume control, mute, menu, and exit. But annoyingly it lacks the, channel up/down, and source input buttons. The remote also 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. More so, Netflix, YouTube, Amazon Prime Video, Disney+ and Apple TV+ can be streamed in 4K UHD. 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. Claimed support for external voice assistants (not built in to the TV) include Amazon Alexa.
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; 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.
ABOUT UHD TESTING: Ultra-high definition "UHD" can refer to both the TV and program content. While the UHD industry standard includes 4K and 8K, most UHD TVs and UHD content at this time are 4K. A 4K UHD image is presented as 3840 x 2160 pixels—four times the pixel-count of HD. We test UHD TV picture quality using 4K UHD movies, videos, photos, and test patterns to confirm these displays deliver performance to this format's full potential. We examine the TV's ability to reproduce 4K UHD image detail, as well as high dynamic range (HDR)—for TVs that support this capability. Image quality is tested using a UHD movie player connected to the TV's HDMI input, and from files stored on USB flash drive. 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.
