Samsung UN55NU8000 Picture Quality


The Samsung UN55NU8000 Picture Quality is a versatile 4k LED TV with good picture quality and HDR support. It also has great motion handling, as only a short trail follows fast moving objects and the TV can flicker to clear up blur. The smart features also work well and the platform is intuitive. The TV includes the Bixby assistant for voice control. Unfortunately, the picture quality degrades when viewed at an angle and vertical blooming is visible in a completely dark room.

Picture Quality

The Samsung NU8000 has great picture quality. The high native contrast ratio produces deep black scenes and the TV is well suited for a dark room. Performance is also good in a bright room, although there are some issues with reflections. This TV can get bright enough for an enjoyable movie or TV experience, whether you are watching SDR or HDR content.

The TV uses a VA panel with a poor viewing angle. The gray uniformity is good with minimum dirty screen effect and so is a good choice for watching sports. It handles upscaling lower resolution content well. White balance and gamma are very good post calibration, although we are unable to correct color accuracy. It has a wide color gamut, although there are some issues displaying greens and any deep, dark colors.


Excellent native contrast ratio on the Samsung NU8000, approximately 15% better than the MU8000. This high contrast ratio allows the TV to produce deep black scenes, especially when viewing in a dark room.

The local dimming feature has very little impact on the contrast ratio. This is to be expected as the local dimming on this edge-lit TV is not very effective at making blacks deeper.

Local Dimming

The local dimming on the NU8000 is bad. It dims the screen less than the MU8000, but focuses the dimming on moving highlights as it should. This helps reduce the amount of visible blooming and the black levels appear raised.

SDR Peak Brightness

Great SDR peak brightness. In dark scenes, the TV tries to keep black levels low rather than favoring brighter highlights. Brightness remains consistent, regardless of content and the TV is bright enough for most rooms.

HDR Peak Brightness

Decent HDR peak brightness, slightly better than last year’s MU8000 but significantly dimmer than the X900F. It is able to produce brief bright highlights especially in the 2% – 10% range. Bright enough for almost all rooms.

Gray Uniformity

Good gray uniformity. The uniformity issues appear mainly around the edges of the screen. As such, the TV’s dirty screen effect is not problematic when watching sports or playing games.

Dark scene uniformity is very good. The edges appear slightly brighter than the center but should not be noticeable.

Viewing Angle

Poor viewing angle. Colors and brightness shift if you are even slightly off center. The side seats of a 3 seat couch will notice a small difference, but people sitting further off center than that will have degraded picture quality. If viewing angle is an issue, an IPS panel like in the X800E would be a better choice.

Black Uniformity

Black uniformity is very good on the NU8000. No clouding can be seen with or without local dimming. Standard deviation is much better than last year’s MU8000, and this year’s X900F, which results in uniform dark scnes without distracting areas.

Like the MU8000, it is impossible to completely disable local dimming on this TV. As such, it is impossible to determine the true native black uniformity performance of this TV. We ran our test with the local dimming feature set to ‘Low’ (the lowest setting). The test for black uniformity with local dimming was taken with local dimming set to‘High’.


The TV reflects a lot of light, but not as bad as other models we have tested like the MU8000. The semi-gloss finish diffuses reflections across most of the screen although there are no visible rainbows.

Pre Calibration

Good color accuracy out of the box, but follows our target of 6500K and 2.2 gamma much worse than last year’s MU8000. White balance has too much red/green and gamma is too high across the entire curve at 2.42. The color temperature is cold at 6032K giving colors more of a yellow tint.

Post Calibration

White balance and color temperature are near perfect post calibration. We were unable to correct color accuracy, although it remains acceptable for most people. We obtained the best results in the‘Movie’ picture mode.

Color Volume

Decent color volume. It does a better job than the MU8000 at displaying bright colors across its entire color gamut, but still does not display deep, dark colors very well.

Color Gamut

Good color gamut on the Samsung NU8000, slightly better than the MU8000. Colors in HDR will be fairly accurate, although the TV has difficulty displaying deep greens. Very similar results to the Sony X900E.

The ‘Movie’ picture mode’s HDR EOTF follows the target PQ curve very well, up until it rolls off into its max brightness. ‘Game’ and ‘PC’ modes also have fairly accurate EOTFs. In ‘PC’ mode the ‘Dynamic’ picture mode has the best HDR EOTF, because ‘Standard’ mode has a bug where it sometimes gets stuck in a dim state.
