We do notice some clouding below the white cross though, but it is very limited. Corners are usually where clouding happens most of the time on an LCD panel and in this case, we can't really show you if there is some near the corner, since the local dimming is turning off the backlight on both sides. Both sides are really black, thus affecting the whole screen evenness. Secondly, when set to low while displaying our test image, vertical blooming is visible in the middle where the cross is.
The first one being that we can't really show you how is the true native black uniformity since, at the minimum, the local dimming can only be set to low.
The fact that the local dimming can't be completely turned off here affects the uniformity test in a couple of ways. The Samsung Q8C black uniformity is below average.
