No clue if it also affects LG's LCDs or any of the other brands that use their panels.

I thought of an 4:4:4 issue (4:4:4 and RGB ... , RGB is always 4:4:4 eqivalent ) because of that info: Quote:

There is no difference between models and years, as far as we can tell. What @chros was referring to was a statement made by Ted over at AVS, claiming that the LGs don't do a perfect 4:4:4, but very close. Nevertheless, chroma patterns are displayed without (noticeable) sub-sampling.

Hi, couple of issues with AMD 19.9.2 ive found, I've moved back to 19.8.1, firstly the vocal volumes were off for me, much quieter then they should be, thought it was my setup but issue was resolved by moving back, to double check i installed again, same issue again, so went back again.
Second issue is corruption when skipping, this is something AMD cards have had on and off for years, it sorts itself out after a few seconds of playback usually so no big deal. Not a MADVR issue I know but thought i should say.

Depends on how heavy the banding in your content is. Low/low doesn't cause any noticeable harm and gets rid of most banding. I leave it on low/low for everything.

As always with compression artifacts, it depends on the source.
I have some MPEG2 SD TV channels that are so bitrate-starved that they need deband on high. The good thing is I find when you have horrible source, that deband on high also has the side-effect of smoothing out other compression artifacts without needing to enable other algos. Image looses some detail but I definitely prefer it to the bands-and-blocks fest that is the alternative.

Hi everyone.
When downscaling UHD->FHD (projector FHD) on test patterns S&M (Chroma Multiburst and Chroma Zone Plate), the Lanczos (tape 4) chroma upscaling looks much better than everyone else (with the exception of NGU AA, I just don't have enough power for it). super-xbr: the test circle looks awful because of the moire throughout the area. Jinc - too very dark edges in the corners. Spline looks a bit darker around the edges than Lanczos. Bilateral is generally terrible. Lanczos visually very similar to NGU AA on all test patterns. I use the SSIM 1D + LL + AR + AB downscaling algorithm. How to choose the right algorithm? According to test patterns, as I did, I chose the closest to NGU (Lanczos for me), which looks great. Or put the most powerful (super-xbr) and not look at the test patterns? |

test pattern can be like pixel art a place where jinc does bad.
i personally ignore test pattern fro chroma and select the chroma scale on real world image where it matters. BTW you could avoid the chroma scaler in your case and use the option under trade for performance "scale chroma separately, if...". NGU AA and super xBR AR are considered to be better choices for chroma. |

Thanks! If I cancel chroma scaling, then there is a clear difference on the real content. I can’t say for better or worse, it's just different. Without chroma scaling bright white-red areas look more blurry. With scaling more compiled. What would you advise to choose:
1) chroma: super-xbr + AR; luma: SSIM 1D + LL + AR + AB or 2) without chroma scaling; luma: SSIM 2D + LL + AR + AB Last edited by Bo.; 16th October 2019 at 10:16. |

Are there any examples out there of what the chroma layer actually looks like without the luma layer (and vice-versa)? Even better if there are examples of a chroma/luma layer upscaled with different algorithms.

I doubt anyone here has the crystal ball required to help you with this, you've given us nothing to go on really, post your MADVR control+J screen and your system and gfx card specs + your video file specs.
