The funny thing is that the typical (old) LCD monitors have greyscale banding. If you think on HSL , on a typical monitor you will have an effective 8-8-6 . Usually monitor firmware try to give the illusion of a effective 8 bit on luminosity channel, doing little changes of colour to soft the banding effect. Intereting the old CRT monitors not have this problem thanks that they not don't do any image processing beyond playing with hue/brightness/contrast (and this could be archived by a few op-amps and a few pots) This my case with my old Samsung monitor, but this monitor have some tricks that helps a lot to see bad softing on 3d meshes thanks to the weird banding/posterization when you look it at extreme angles.
