problem with vertically placed screens

  • Hello,
    I found a problem with veyon and verticaly placed screens. If my teachers screens are 2(left) and 1(right) it runs without problems. But if i setup my screens with 1(left) end 2(right) or 1(top) and 2 (botom), or 1(botom) and 2(top), or all sort of not default setup, i can't stream nothing, only black screen. i tryed witch many different versions on veyon, but it is the same problem everytime. Actually i use the last version (4.5.6). Please help, i don't want to switch to netsupport.
