game streaming black screen

Discord has problem with my main monitor BenQ EX3203R @ 2560x1440 all games will get black screen with auto.

When I switch the game to secondary monitor BenQ El2870U @ 2560x1440 it will have The images and auto, so right now Discord do not like my BenQ EX3203R 144hz curved gaming monitor. this a bad problem for me as I like to steam my game play to my friends on my proper gaming monitor. (Discord Has Issues with My monitor and needs fixed)
