hello everyone, im trying to play games from steam but i have problem which i cannot find solution for it.
when i had just one screen MSI MAG341CQ everything was perfect,but i added a second screen below the first one ,its a Acer PM161Q A ,portable one,things started be funny .just when try play games,otherwise no problems at all. when started ,game takes both screens,going even beside frame of the physical screens,completely not playable. before i start with steam,i followed dicovery.endevouros for driver,vulcan and all fun stuff there w/o problems with installation. nvidia drivers loaded(rtx3060 gpu),vulcan loaded all looks works fine except screens. when i had mx linux with same setup,games showed up on bigger screen not affected 2nd one,but most of them wasn’t run 
did anyone here have similar issue? any solution? thx in advance.
