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 Very Good (with the backlight control turned up), so the picture was well suited for a brighter room—a lower setting is recommended for a dimmer viewing environment. Its reproduction of smooth edges on image content for "up-converted" HD-to-UHD images was Very Good with minimal "jaggies" (jagged edges), but deinterlacing of 1080i video fell short with some visible "jaggies". The 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.
VIEWING ANGLE This Toshiba model 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. In our tests, the picture did show moderate dimming from the sides. When we viewed the TV from the sides the image quality degraded significantly. The picture showed a strong loss of color, so flesh tones looked very washed out. Black levels brightened significantly, and made dark scenes look hazy. 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.
