A shader that specifically tries to emulate Bang & Olufsen with a slot mask screen but with full brightness.
A shader that specifically tries to emulate Bang & Olufsen Beovision with a slot mask 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 slot mask 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 XXXX CRT MAKE MODEL XXXX.
Currently defaults towards a Bang & Olufsen Beovision MX8000.
To use:
Please Enable HDR in RetroArch 1.10+
