Sorry the slightly confusing thing (ok very) is that this shader because it is natively HDR overrides any settings in the RA->Settings->Video->HDR menu (apart from turning on HDR itself that is). Instead use all the options in the ‘Shader Parameters’ menu underneath Quick Menu->Shaders.
Ah, that’s why nothing happened when I tried changing the settings there, quite confusing yes
Things do change when editing the shader parameters though.
Just to say you should probably put your TV brightness up to max. However this may not work when using HDR as HDR is supposed to override local settings but just in case…
Brightness is at 100 on the TV, or are you talking about some other brightness?
With LG TVs it’s also important to change the label of the HDMI input that you’re using to match your input device. I have mine set to PC for example. I also use HDR (Game) colour setting.
You might want to lower your Peak Luminance value following @wilch’s advice.
You may also have to adjust your Black Level and Gamma settings for the Input. Power saving settings also significantly affect the brightness of the screen.
@Cyber: Yep, I’ve changed the input to PC as well to be able to use 2160p@120hz.
I think I’m using the same Peak Luminance as @Wilch. 720?
Power saving is completely off, like you say it ruins the brightness.
When you say black level and gamma for the input, you’re talking about TV settings right?
Black Level settings are Low/High/Auto where I have Auto.
Gamma is grayed and can’t be changed, but looks like it’s at 2.2
