i have jedi fallen order and 3440x1440 120Hz Monitor

I Have purchaed jefi falling order and encounter an annoying problem.the game can display full screen on 3440X1440 Resolution but movie clips and etc

it does not.i am amazed that 2020 brand new game does not have full support in 21:9 ultra wide monitors like my dell alianware aw3420dw monitor even gta games does have such problems and they are like at least five years old.your thoughts guys?

thanks in advacne of course.🙂
