A shader that specifically tries to emulate Sony PVM's with an aperture grille screen but with full brightness.

The novel thing about this shader is that it transforms the image output by the 'console/arcade/computer' into HDR space first i.e brightens it first and then applies

an aperture grille afterwards which is kind of what a CRT would actually do - its kind of a kin to the electron beam (but nothing like it lol).

My DisplayHDR 600 monitor does seem to get reasonably close to the brightness of my PVM - its not quite there but its close. I think DisplayHDR 1000 and above will be able to match.

Currently defaults towards a Sony PVM 2730QM a reasonably old mid 1980's 27" 600TVL pro monitor.
v1.0 of Sony PVM 4K HDR shader that tries to emulate a Sony PVM 20L4 CRT. Again requires a HDR capable screen typically of at least 700 nits (but may need less for OLEDs) This version adds support for different resolution patterns see shader for more details

NOTE: when this shader is envoked the Contrast, Peak Luminance and Paper White Luminance in the HDR menu do nothing instead set those values through the shader parameters

Refactored shader to support shadow and dot masks - added crt-shadow-mask-hdr.slang, crt-dot-mask-hdr.slang Added Bang & Olufsen TV preset (shadow mask) Added Toshiba Microfilter TV preset (dot mask) Renamed crt-sony-pvm-4k-hdr.slang to more general crt-aperture-grille-hdr.slang Moved header files into an include directory

For this shader set Paper White Luminance to above 700 and Peak Luminance to the peak luminance of your monitor.

Also try to use a integer scaling - its just better - overscaling is fine/great.
This shader doesn't do any geometry warping or bouncing of light around inside the screen - I think these effects just add unwanted noise, I know people disagree. Please feel free to make you own and add them

THIS SHADER DOES NOT SUPPORT WRGB OLED (Due to the sub pixel layout of WRGB - QD-OLED or LCD (and variants thereof screens are fine)

Major improvement to the Sony PVM 4K HDR shader Refactored it into a single pass for simplicity and speed Rewrote a lot of the curves Defaulted to a new mask RGBX Added ability for scanlines to overlap Broke out HDR and inverse tonemapper into headers

Simplified the shader framework to have one master shader instead of three which meant I can remove a whole load of files
