Just playing around, trying to configure @guest.r’s scanline-mask shader for a 500 nit display using my iPhone 6 screen. My goal is to max out the mask strength while maintaining adequate brightness, contrast and color. Maximum mask strength is required for accurate CRT phosphor emulation, with the phosphors displaying accurate RGB intensity values.
Final(?) edit (1/16/2020):
These must be viewed full size on a 1080p display and you need a display with a max brightness of 500+ nits with the backlight cranked up to 100%. If these aren’t viewed full size at 1080p then the mask/scanlines get scaled in a way that makes the images a lot darker. If you don’t have a display with 500+ nits, the images will be unacceptably dark. For 350+ nit displays (most LED-lit LCDs), check out these settings.
Overall, I really like what I’m seeing regarding scanline shape and variation! Compare the screenshot of Sonic 3 to the photo of Sonic 3 on a Sony FV310.
“Max backlight” settings for a 500+ nit display:
-scanline edges at max -scanline center at max -gamma at 3.00 -crt mask dark at 1.00 -crt mask bright at 1.00
inner bars should be just barely visible in a dark room:
