i could use a supergun with old double dragon jamma and picture was correct. but trying some recent Cave (mushihime futari, pinksweets) the colours have heavy gamma, it's nearly white & some very light red/blue/green
how could i lower the luminosity ? (tried from setup tv, but couldnt be better, ... reminds me a bit from these 5" thrustmaster rgb screens who had very white colours too) . this supergun was normal one and used to work good with crt monitors ...
dont have very much time at moment , so i will be very pleased to read if someone had this kind of trouble & found an answer
