Differences between sizes

We reviewed the 55" (XBR-55X850C). It is the only size that is edge-lit. Bigger sizes usually have worse black uniformity, but that shouldn't be the case here due to their direct backlight. If someone finds another significant difference between sizes, let us know and we will update our review.

Overseas, the 43" version (43X8500C) has an IPS panel (as reported by one of our visitor, who took this picture).

Motionflow Clearness

Instead of last year's Impulse mode, there is now a slider called 'Clearness' that changes the duty cycle of the backlight flickering. Increasing 'Clearness' reduces the duty cycle, making the picture clearer, without motion interpolation (the soap opera effect). The frequency of the flickering stays the same, though (120Hz), except when it is set to the max, where it drops to 60hz.

Using this feature darkens the picture and also introduces some visible flickering, so it is not for everyone. This can be used in game mode, as it doesn't significantly increase input lag.

Here are the pictures of the different values, as well as where the Samsung JU7100 fits visually.
