Does the last firmware give us some improvement? (nothing was mentionned in the update log )
Sorry - no change yet.
I use color range from 0-256 and colors of vivid - thats looking good on my deep color TV. I know, that 0-256 is only for monitors and not TV but that cured the missing blacks until a clean solution
You my friend may have given us a clue as to what the problem is!
In earlier firmware the quantisation range (0-255, 16-235) was completely screwed up. That got fixed, but I now wonder if they didn't fix it for the VS10 engine and only Realtek...
By the way, if you use VS10, the HDR>SDR Gamma Settings (Bright, Vivid, Movie Mode) have no effect - they only apply to the Realtek engine.
OK, thanx, i have switched a lot on the settings to get des VS10 running, because the pictures is a lot better than with the realtek engine (on my non-HDR-TV), good to know that that settings are ignored. But the "trick" with 0-256 works
Hey, this could be revealing indeed. I would have never thought of this trick.
Good for you both, @tosh123 and @Markswift2003 ! [thumbs up]
Curious to Zidoo's response.
I can't take any credit for this one, but @tosh123 is right - it makes a big difference, although it looks like black clip is a bit worse - I'll test this properly later.
Good .... you gave me the idea to test the calibration with the 0-255 color space !!
Well that's not bad at all, because with 16-235 test charts, I was able to calibrate the blacks and whites more easily !!
So for the moment, while waiting for a correction on the 16-235, I stay with this calibration of which I am less obliged to lower the brightness (I have recovered about 8 notches of brightness!).
In the end, after a day of testing in 0-255, I returned to my settings in 16-235 ........... which in the end suits me better!
While waiting for a correction from Zidoo!
Which HDR mode are you using?
-Dolby Vision VS10 Engine.
-Optimize EDID analysis in LLDV mode.
Not sure what that means?
And is it an SDR, HDR or DV display - just curious.
Not easy to explain my installation because I go through my OPPO 203, which accepts SDR-HDR-DV and then depending on my broadcaster: 1) in 8K 2) false 4K non HDR projo, I make the settings accordingly!
I just noticed that for the same settings of the OPPO, the image was more 'dynamic' when leaving the Zidoo in 16-235.
It's just my visual appreciation!
