For anyone having trouble using LG OLED panels, specifically in regards to brightness, I figured out the optimal settings to get a very bright and vivid picture even with black frame insertion on.
Windows 11:
Turn on HDR and Auto HDR.
I also like to use the SDR-HDR slider and crank it to the max but this is not necessary, I just like using windows in HDR.
Make sure to calibrate using the windows HDR calibration app.
Retroarch:
Driver: Vulkan (VERY important, if you have it set to GL then HDR won’t work. D3D12 also works but not on all cores (for example can’t use GlideN64 with D3D12).
Video: Integer scaling on. I also like to use integer scale overscale, as this makes the picture bigger without sacrificing much of the image.
And obviously HDR ON.
Shader settings (I like the Megatron default shader)
Paper white: 800 (by default, this is set to 200. This was what had the biggest effect on brightness for me)
Peak brightness: 800
—I have an LG C1. If you have a newer panel you can probably set both of those numbers to 1000 or higher, based off the the maxCLL for your panel which you can find on multiple websites such as RTrings—
Under CRT settings I bring down saturation, brightness, and contrast to 0 (if not already done so by default)
Sub pixel layout: WRGB.
Gamma: adjust to taste (I like 2.4).
You can also play around with TVL and beam size settings.
That fixed the brightness for me, and actually the picture is very bright even in a decently lit room.
LG OLED settings:
Especially If you’re interested in better motion clarity.
For black frame insertion you can either use retroarch internal BFI under latency settings, or you can use OLED motion pro.
It doesn’t really matter what picture mode you’re in as long as you have peak brightness set to maximum. I leave brightness (black level) at 50, and for temperature I set it to warm50.
Dynamic tone mapping: On (in most settings this is brighter, sometimes HGiG looks better, you can play around with this and see what you like better)
Hope this helps anyone else!
This shader is so good, especially with BFI, that I find I really don’t have to use my RGB modded trinitrons any longer as especially from afar I really can’t tell a difference/they are really close.
If anyone figures out how to append a curved CRT effect to the shader, let me know.
