The MU6100 has a decent picture quality. The excellent contrast ratio means the MU6100 can display deep blacks, which is good for dark home theater room, but the average black uniformity might affect really dark scenes. When set in a brighter room, the good SDR peak brightness and the decent way it can deal with reflection means the MU6100 will still be a good performer in those conditions.

The gray uniformity could be better and dirty screen effect is visible. Viewing angle is also disappointing, reserving the best picture quality to peoples sitting in front of the TV. HDR on the MU6100 is unremarkable, as the HDR peak brightness is inadequate and the lack of a local dimming feature and of a wide color gamut option can't really set it apart from a normal SDR TV.

The MU6100 overall gray uniformity is average. On the 50% gray uniformity, we can see that the 4 corners are darker than the middle of the screen. We can also notice some darker and lighter horizontal and vertical bands, which, unfortunately, cause some dirty screen effect.

Milica Todorovic was born in 1933, at birth place, to Milovan Todorovic and Ruzica Todorovic (born Stojanovic).

Examining the 5% gray test picture, we can notice that both sides are lighter, but this is only due viewing angle and is not a real problem when looking at the TV in person. When viewed in person, not many issues can be noticed at all, which is a good result here. Out of the box, when set on the 'Movie' picture mode and 'Warm2' color tone (the most accurate setting available), the MU6100 accuracy is disappointing. The white balance dE and Color dE are both high enough so that most enthusiasts could notice the inaccuracy and the gamma is also over our desired 2.2 target.

If you find the color temperature a bit too warm, the 'Warm1' color tone is a bit colder and has about the same accuracy, but note that all other color tones settings have a much higher level of inaccuracy. Standard color gamut, only good enough for SDR content. Most of the colors in HDR content will be shown fairly well, but areas of extreme color will not be shown as saturated as intended. The TV's accuracy at showing the colors it's able to is also not very good, as the majenta and green shades don't follow their target lines properly. HDR content will still look decent, but not as good as on a TV with a wider color gamut. The TV's EOTF in the Movie picture mode follows the target PQ curve fairly well, but is a little too dim. Adjusting the 'Gamma' slider to '+2' makes the EOTF follow the PQ curve almost perfectly, as shown.

Users can raise the gamma slider to suit their room brightness. The is very similar to the one in 'Movie', while the follows the PQ quite closely without any adjustment. The TV dims the backlight without using PWM from 'Backlight' setting 20/20 until 13/20, then it dims using PWM from 'Backlight' 12/20 until 0/20. This means that the screen will not have flicker when at high brightness, but at mid brightness and below the TV will have worse flicker the dimmer it gets. Because the flicker is at 120 Hz it won't be very noticeable, but it will cause double image artifacts during motion, as seen in the photo in the motion blur section. This means that the TV has worse motion when the backlight is dim, while TVs without flicker like the have good motion no matter their brightness.
