Not to resurrect and then derail a three year old thread, but, what the heck.
I’ve also been using the “backlight trick” for a while now to compensate for the lost brightness resulting from applying scanlines, and it works very nicely with my ASUS VG248QE. The only downside is that this raises black level somewhat, but this isn’t noticeable when playing a game and it’s a necessary compromise.
With HDR, it will be no problem to compensate for the lost brightness resulting from scanlines and mask effects. Current LCDs are just barely bright enough for CRT emulation and are easily washed out when mask effects are applied. A strong backlight and a dim/dark room are required.
Here are my current settings (CRT easymode is just a bit too much for my Intel NUC6CAYS):
bilinear filter: off
integer scale: 6x5
Shader #0: Zfast CRT+dotmask (see: “combining shaders”)
Shader #0 filter: nearest
Shader #0 scale: don’t care
X axis blur: 0.00 (this adds some slight blur compared to nearest neighbor but is nowhere near as blurry as bilinear filter)
Scanline darkness low: 9.00
Scanline darkness high: 8.00
Dark pixel brightness boost: 1.00 (off)
Mask effect: 0.00
Mask/scanline fade: 0.60
Lottes mask effect: 2.00 (aperture grille)
Lottes mask dark: 0.20
Lottes mask light: 2.00
edit: updated my shader settings.
