How much vertical dispersion is needed? An M22 with it's top edge flush with the bottom of the display angled up slightly shouldn't have any problem. I just don't have even that much room, my VP150 covers the Pioneer logo on the bezel of my display.

Pioneer PDP-5020FD, Marantz SR6011
Axiom M5HP, VP160HP, QS8
Sony PS4, surround backs
