Black level in Mednafen PSX is too low

Has anyone else noticed this? The black level is just way too low in Mednafen PSX. I have to crank the brightness on my monitor all the way to 90 or I lose detail in dark scenes and the blacks just blend together in a dark blob. Is there a way to change this in the config file maybe?

Can the black level be changed to the correct level for a future release?

You should ask in mednafen’s forum I guess, for me the output is exactly the same colors as in mednafen standalone
