My eyes just bad or is my screen doing something to smooth out the gradients (like dithering, I would assume)?

On a typical LCD with 1000:1 contrast TV/Monitor 8bit is almost enough, but still visible on a smooth test pattern. A video/movie is not a test pattern, you will not be able to see any difference between 8 and 10 bit at all.

I´ve tried your test with my Panasonic TX-50AX800E 4K which is supposed to support 10bit but failed to see differences between 8bit and 10bit. Followed your instructions in madVR config. Any ideas ?
Have I understand correctly the fact that 10bit needs FSE mode ? Thanks! |

and yes FSE is needed for 10 bit. |

There is however one problem with that test (with or without debanding). If i try that on a display which I know is 8-bit only, it still looks better in 10-bit FSE mode. Maybe the GPU dithers, or the display itself. I can't be sure. But i don't get the 8-bit picture which I would get from windowed mode.

I suppose this is confirmation then BTW. I can`t see the mouse pointer in FSE, so seek bar is unusable, anybody else? Last edited by phoenix369; 11th May 2015 at 18:32. |

This gradient video by itself is NOT smooth that is why I use debanding to make it smooth because of 16bit madVR's processing. Of course you'll see the gradients of this video with debanding disabled! The whole point is to have a true 16bit smooth gradient and output true 8bit or 10 bit pattern without Dithering (which should be disabled). A true 16bit gradient video would be ideal.. Where is VerGreeneyes when you need him. Confirmation of what? That your TV does not support 10bit?

Didn't know that, but there's probably nothing I can do anything about it. |

When I switch to FSE in 10-bit I can see the banding in the gradient clearly. Non FSE 10-bit looked like 8-bit. Is this the expected result for a 10-bit panel? |

I have both a 10-bit capable LCD TV (Vizio M602i-B3) and a not sure-bit capable Plasma (Panasonic P55UT50) connected to my PC via up to 16-bit per channel active hdmi cables. For what it's worth, using grayscale ramps:
I can't really tell on the Pano plasma. I suspect this is either because the TV itself does a lot of dithering and/or it's not 10-bit capable. Anyway, I can't really see a difference so I've left it at 10-bit. There's definitely no degradation; so, my assumption is that it's either the same or marginally better. The 10-bit capable LCD looks a lot better; even with error correction on. The gradients are super smooth in both 8 bit and 10 bit but I can see an improvement. Overall, I'm a fan. I can't see any drawbacks to outputting 10-bit. EDIT: Even though I haven't seen any drawbacks to 10-bit, I definitely wouldn't try to output 10-bit over, say, single-link dvi or an old hdmi cable. I wonder if it would be possible to create a test for this; say; by putting 8-bit and 10-bit grayscale ramps next to one another. Last edited by Moony349; 11th May 2015 at 18:59. |
