Theater mode screen distance and size

[gufo2k20]

Hi all....i like VR theater mode for some non-VR games and i'm trying to test some sims with OpenTrack-VR headset option......but, VR theter screen it's a bit too far,
Is there a way to change the distance?? even resizing to the max it's still to small and far away

mine just shows a big screen in front of me when i try to go into steamlink on my headset
