Vizio M8 Series Quantum 2020, not high end but it does have HLG, HDR10, and Dolby Vision. I used my measured max brightness @D65 and I got the 203 nits number from here: https://daejeonchronicles.com/2021/02/13/hdr-reference-white/#:~:text=While%20typical%20white%20levels%20presently%20used%20in%20PQ,%28input%29%20level%2C%20as%20shown%20in%20the%...

hdr_max_nits=770 hdr_avg_nits=203: With these settings, Contrast TV control is a LOT more effective than with higher previous settings. With HLG adding contrast also adds color as well as brightness as if the contrast controls the exposure level. With DCI I can make the image too dark or too bright whereas TV contrast didn't do much at all previous...

Thanks, Natrox. For SDR to HDR conversion, I've heard 400 and 1000 nits being tossed around, but I've also heard 550 and 4000, especially for HLG. I don't remember where I read it at the moment, it's just a curiosity, but I'd just like to exhaust that avenue before seeking other solutions. I tried those numbers on Retroarch and it enhanced both col...

That's very generous, how cool. I'd love to test a build, thanks! I wouldn't need OG mode 3 back if we could get regular HLG brighter, it might have potential. It's almost there. I'd say if people were having difficulty with 10000 nits we could try 4000 nits for the high figure. I wonder if a higher MaxFALL like 520-550 nits would do anything to br...

I am not sure what you are referring to. I have not made any changes to HDR recently, aside from moving HLG to hdr=1 and DCI P3 to hdr=2 (BT2020 was removed). I greatly appreciate your contribution of HDR and am sorry if I came off as harsh but there have been changes. To explain: When HLG was on option 3 it still registered as HDR10 on my TV and ...

You can try raising the color on either your TV or the Mister.ini but yeah I did notice a change there vs. when HLG was mode 3. Thanks. I can't because it's 444 with greyed-out options on my set, so the only adjustable parameters for HLG are brightness, contrast, tone mapping, gamma, and local dimming level. All do very little and it seems that th...

@Natrox I don't know what happened to the HLG option, but now it's dim and colorless. No amount of tone mapping is even brightening it up. I guess the critics won, because It doesn't even look 'just' like SDR at this point, it's bland. Please don't do that to the DCI setting, leave it the way it is. It's Arcadish and I had been trying to get that l...

I'm liking this new feature! The darker low midtones seem to be reminiscent of Wells Gardner CRT arcade monitors with the DCI setting, whereas the HLG seems to evoke more of a Sony CRT look. Probably just a coincidence, but I think if we could properly characterize a raw CRT with its gamma S-curve and map that onto HDR we might just be onto somethi...
