I'm having issues with changing display modes automatically with profiles.
Does anyone know if there is any bugs with this? With no profiles madVR changes display modes as expected, but when i set up profiles it doesn't. The correct profile is marked with bold text in madVR settings, so I believe the correct profile is selected, but it doesn't do anything. My profile rule is simple: Quote:

Has anyone experienced anything similar? |

I don't want to use 23,976Hz (and) 24Hz since my TV then reduces to 4:2:2 chroma subsampling. Personally I prefer some frame repeats and full chroma than less frame drops/repeats and reduced chroma subsampling. The exception is HDR, which I want to transfer with 12/10 bit resolution which I can't do with higher framerates and therefore want 23,976Hz for that. |

My model is an NU8000 (UE82NU8005)
The chroma issue which apparently is a Samsung thing is that when the refresh rate goes down to 23 or 24 Hz the TV switches from 4:4:4 chroma to 4:2:2 chroma, even though it shows it's still in PC-mode. I've double checked with test images, and everything from 29Hz and up is full chroma. I'm not sure about 25Hz, but both 23,976 and 24Hz is 4:2:2 chroma. |

Maybe it's because you use PC mode. That always limits a panels capabilities. Perhaps some other 'different' settings and/or drivers for some reason too? Imo, I don't think it's a panel problem you have. My current Samsung and all of my past Samsungs never had 4:4:4 problems at any resolution but I'm using different settings than you.

Many people have this problem with different samsung tvs.
ex. https://www.avsforum.com/threads/do-...nitor.3116496/ or: https://www.avsforum.com/threads/201...056264/page-46 I see in the last link there's a bug that might be exploited to get 4:4:4 chroma in 23/24Hz. I'll try that later when i find time. |

As I said, maybe it's because you use PC mode.
Here is a direct quote from the 1st link you provided. It's one of the last posts in the discussion: "I found a way to permanently fix this. (Otherwise I would definitely have had to return the TV.) YMMV. I labeled the TV as "Game Console". This fixed the issue. Then I changed the label back to "PC". The fix stayed. Yes, it was a gigantic dealbreaker until I found the solution. I spent a lot of time plugging away at Samsung's customer support chat over the issue. They were no help; I had to discover it myself. That it can be fixed at all is, of course, a totally random miracle, because it's certain that Samsung doesn't care and won't be fixing it themselves in any capacity more proactive than accidentally. And I also acknowledge that probably nobody else even knows it can be fixed, despite the latest firmware." Fwiw, on my Q90R and all my former Samsungs, I edit my source to 'Blu-ray Player' and leave it. Note that the quote above is relabeling the source a couple of times while I simply edit it once. Keep in mind this is the madVr thread and we are getting way off topic. @Klaus1189 When you adjust the panel to anything but PC mode, there is no overscan issue. The switch to enable 'fit to screen' becomes active once you get out of PC modes limitations. Doing this also allows the color space selection to be enabled. On Samsungs when using a PC you would select 'normal' which is 0-255 and RGB.

I'm not understanding about having to use PC mode? I don't use PC mode. I never have on any of my panels other than testing. PC mode looks terrible no matter what settings are adjusted and many will be greyed out or unavailable which decreases any chance of viewing an acceptable picture. Movie mode isn't even available and I definitely want the algo used in that mode vs the only other two modes available when using PC mode - Standard or Dynamic. To enable 4:4:4, I select what Samsung calls 'Input Signal Plus'. I look at the test pattern 'quick brown fox' and I can read every text perfectly. I assume if 4:4:4 was not working, the text would be blurry. Also, because 4:4:4 is RGB (mixtures of red, green, and blue) if I wasn't getting 4:4:4, reds would take on an orange tint. I think this is an inherent tell tale sign on Samsungs. I'm only interested in video watching. This discussion isn't about gaming is it? If you would be kind enough to increase my understanding and how it would benefit my/our usage, please elaborate. Thanks.
