Exactly what SSJBen said , I was going to post yesterday but forgot to submit my post until this morning .
The problem lies with the HGIG standard within the gaming industry .
These settings only apply to games that comply to HGIG standards.
The Assassin's Creed series , for example , use their very own settings for HDR .
They have been using Rting's display to calibrate their settings for Odyssey and Origins .
From my observation , it is pretty accurate and they should be applauded for providing options to the players .
The other notable mention includes God of War .
AC : V , on the other hand suffered from alleviated exposure . One example on these are the face features of the secret ancient orders are revealed when it was just supposed to just show their silhouette .
Turning down the exposure will fix this but will also crush the black details slightly .
Cyberpunk2077 also offer the same settings but completely screwing up the midtone and black foundation .Β
To make matters more complicated , some of modern days TV have built in , undefeatable dynamic tone mapping , which will overwrite your default tone-mapping curves regardless of settings .
Therefore , until HGIG has become widely available , supported and embraced by game developers , the setting are not going to be helpful in every situation .
P/S : 800 for your X90H is correct. Contrast enhancer should be off , black level & color should be 50 by default .
I would change local dimming to medium for X90 because it has limited zones , high makes local dimming zonal transition too distractive .
For Gamma 0 is the correct number for HDR , equivalent to 2.2 of other brands . For SDR , -2 for dim room , 0 for typical environment with ambient lightings .
Thanks for your great input. I really appreciate it. Yeah
made me do some reading about HGIG vs DTM.
There is no option or any sort of settings to switch DTM on or off or HGIG for my X90H unlike the LG CX right?
Okay I will setup using your numbers tonight.
"for the local dimming zonal transition issue" is there any source I can refer to? I want to know my 32 zones limitation.
