After finally having found some time to enjoy my 55B7V during these Christmas holydays, here an additional v8.1 update for you!
Many little tweaks in most profiles + a brand new Option for HDR gaming. You can find the full changelog below.
Enjoy and have an Happy New Year!
- New Option 2b added for HDR gaming! This is a new try to revitalize the "PC Mode/Input Icon" alternative for gaming, and it basically consist in using the pure and most accurate/calibrated "HDR Game" preset with no Dynamic Contrast enhancement at all. The main advantage is keeping 21ms low input lag in HDR (opposed to the 40-ish ms of PC HDR Standard) for those people who prefer "PC Mode" for its superior SDR + 4:4:4 + RGB Limited + ISF Preset compared to SDR Game. The "pure" HDR Game (with no DC) should also look perfectly bright for all the best and/or recent HDR games which allow setting peak HDR Brightness value to 4.000 and/or Paper White to 200 and/or White Point to 0.9; it will also look good with all 1.000 nits contents and also 4.000 nits HDR Movies and TV Shows with lower MaxCLL, which should be the majority (thanks to recent LG silent improvements to HDR Cinema/Technicolor/Game presets' MaxCLL tracking). Dimness issues should be limited with games/movies mastered at 4.000 or 10.000 nits with no sliders control at all, with no MaxCLL values or MaxCLL values extremely high (minority of cases, but still possible);
- When using Option 2 and PC Mode in general (SDR/HDR/DV) it is crucial to disable/uncheck 4:2:2 chroma subsampling and stick to 4:2:0 in order to avoid severe color banding in all modes. This was reflected in the docs by unchecking 422 on X1X and selecting 2160P YUV420 resolution on PS4 Pro;
- When using Option 2 and PC Mode in general, X1X Color Depth is back to 8-bit + Standard Color Space: this will make the console output an uncompressed 4:4:4 RGB Limited signal for SDR (the best you can get) while using calibrated ISF Expert (Dark Room) with Auto Gamut (goodbye forced Wide ) and keeping 21ms low input lag. With 422 box unchecked, both HDR and Dolby Vision will automatically switch to 4:2:0 chroma, with no color banding and almost unpercievable difference compared to 4:2:2 outside of PC Mode;
- ISF Expert (Dark Room) OLED Light was slightly decreased from 70 to 60 as it was a bit an overkill in a dark room;
- SDR Game Mode OLED Light was therefore lowered from 80 to 70 to match the new ISF luminance in SDR;
- HDR Technicolor Expert Brightness was slightly decreased from 50 to 49 to offset very slightly elevated blacks caused by Active HDR
