Hi10P and 8-bit encodes

If TV->PC levels conversion and/or YUV->RGB conversion is done poorly, you will create banding which doesn't exist in the source.
You or something you are using is doing something is doing something that hurts quality. Since this actually shows up in your screenshots, I'd suspect PotPlayer, or how you have PotPlayer set up may be to blame. Could you retest using MPC-HC + FFDShow with a standard CCCP install? I'd also like to see you take a screenshot with madVR, which will avoid anything your GPU Driver may or may not be doing which hurts quality.
The other factor is your monitor. Especially in the past, there were many LCD displays which would show banding when displaying a smooth 8-bit gradient. Do you see banding in any of the following smooth gradients?
RGB Spectrum
RGB Linear Gradient
Gray Linear Gradient
Red Linear Gradient
Green Linear Gradient
Blue Linear Gradient
Gray Horizontal Gradient
Gray Vertical Gradient

OK... tell me you're pulling my leg here?!? These things don't look smooth at all. o_O
BUT... I'm 250% sure I've seen plenty of gradients without banding on this computer and this monitor. Hell, no ass in porn ever looked banded... And even the less-banded screenshots of EveTaku Bento look - well - less banded... and no photograph has ever shown banding or gradient problems... AND I've watched plenty of banding-free animes, encoded at anything from ~700 to 6000+kbit/s, resolutions from sub-SD to FullHD, with none of this crap happening.
Plus, hell, even the background of the "topic summary" stripe here has a gradient - and thas all nice and smooth? And windows aero looks plenty banding-free??
...what gives?!?

EveTaku Ben-To 01v2 8bit (359.3 MB) w/ EVR-CP
EveTaku Ben-To 01v2 10bit (304.1 MB) w/ EVR-CP
EveTaku Ben-To 01v2 8bit (359.3 MB) w/ madVR
EveTaku Ben-To 01v2 10bit (304.1 MB) w/ madVR
None of these look as bad as your screenshot and I'm not doing anything special. Decoded Video -> Renderer, that's it.

ACTUALLY... madVR looks better (with madVR 8bit best, slightly better than madVR 10bit... but EVR 8bit and 10bit tied for worst, with 10bit perhaps even worse???) ... and both the EVRs, for whatever reason, look just as banded as my own screenshot *on this screen, as connected to this computer*. Ok,what gives?!?!

Well, that settles it then. It's either your monitor, or your eyesight.
Aadieu:
Ok, seeing as how the rest of the world don't look banded and there ain't any such eyesight disorder anyway - what the hell is wrong with my TV??? And why does it only show some banding, but not across the board? And why almost none in madVR screencaps?!?!
Bob2004:
The reason those gradients that cyberbeing look banded is because most of them aren't smooth gradients - ie. the colour changes in bands anyway. That's what they're meant to look like (a couple of them aren't - such as the RGB Spectrum and grey vertical gradient).
And if the problem was your monitor, then obviously we would not have been able to see it in your screenshot, would we? The screenshots would look identical to us if your monitor was the only problem.
Your software is most likely what's causing your issues (although your monitor and/or eyesight might also be problematic). My advice is to just completely uninstall PotPlayer and whatever else you're using, install CCCP, and see how it looks at default settings in the included player, without changing anything. There should be a noticeable improvement.
Anyway, this thread has gone massively off-topic now. The discussion has pretty much run its course, so maybe someone should lock it?
