you can test it with this image: http://www.bealecorner.org/red/test-...ient-16bit.png
it's not easy to do but there is a trick that will help send 12 bit RGB (a really good 1080p screen is mostly better) use MPC hc/be use WFS 10 bit with the image and and now right click.
when you right click you should see heavy banding when it switches to 8 bit output and shortly after that it should disappear and should have less banding or no banding in 8 bit WFS mode so it should have less banding then WFS 10. FSE 10 bit should show less banding too.
tested on 419.17 if this is a GPU driver bug everyone should be affected.

Good find, @huhn! I could recreate the issue. (see my signature for more details on the setup I use)
- 1080p 10 bit (8bit+FRC) TV
- nvidia v385.28 driver is set to Full range, RGB, 12 bit
- MadVR is set to:
-- "10 bit or higher"
-- "Ordered dithering" is On!
It didn't matter whether I set dithering to None or Ordered!

I couldn't really tell the difference in banding between FSE and WFS, I could clearly see it in both.

It does for me, see above.
Interesting thing is that using the same TV with my old laptop (optimus system, with intel driver + win8.1) I didn't have this issue with 10bit FSE.
