I've never owned a plasma, but I've looked at them up close at retailers and gone through all of the menus.

All the 1080p models I'm seeing now don't display a stable picture like an LCD. The pixels vary in value constantly. Once I showed a sales guy what I meant and he tried to claim it was caused by splitting the video too many times. He thought I was crazy for believing that HDMI doesn't degrade by being split.

But anyway, you don't need to look for a split signal to see this. Just pull up a solid-color menu. Obviously these are generated internally in the display's processing and external source problems don't factor in.

Solid blue menus appear to have grainy patterns.

Is this 8-bit dithering? Shouldn't that not impact blocks of solid color, only gradients? At first I thought it was the anti-burn-in tech but I disabled those via the menus.

LG B7 (OLED65B7P, 2017 -- bought 2017/05/31 & I couldn't be happier so far!) | Panasonic CX850 (TC-55CX850U, 2015 -- bought OLED to replace it due to poor off-angle, weird HDR colors, etc.)

Thats regular plasma dithering - not meant to be watched up close, view plasmas from 6feet+ distance.
