No, it supports 1080p, 8K and also 1440p screens as well. It’s just optimized for my particular taste in TVL on 4K displays.
Yes, you can adjust the “Display’s Resolution” setting in Shader Parameters to 1080p if you have to.
You can also adjust the TVL to whichever value you like best.
You should definitely adjust the "Display’s Subpixel Layout to what looks and works best on your particular output device. My Presets have it set to RWBG (OLED) because that matches the Subpixel Layout of the display that I use, which is an LG OLED TV.
Other displays might be better off using either the RGB (0) or BGR (2) setting.
You can toggle the SDR/HDR setting in the Shader Parameters to SDR for a non-HDR screen/display device.
Brightness (aka how many lumens it can output) is the only limiting factor where this is concerned.
Do note that for SDR displays, you can further optimize things by choosing the Colour Space setting which matches what your display is capable of outputting.
After you do all of these tweaks you might find things look too dark or too washed out. If so, you can fine tune the Gamma setting and lastly the Saturation setting.
Do note that Peak Luminance and Paper White Luminance have no effect in SDR mode.
Instead, you have to turn up the brightness on the display device until things look good.
Also feel free to try out the included Sony Megatron Color Video Monitor SDR presets in the Shaders/Shaders_Slang/HDR
folder.
I’m looking forward to seeing your results!
