how to adjust vertical aligment with vireio??

[ferslash]

guys, i am totally new to hmd, i jumped in making a hmd, using a 7" 1024X600 screen designed to be used with raspberry pi, i 3d printed my googles but... when i try to use tridef or vireio i realize that my screen is not perfectly aligned with the middle of my google lenses...

is there a way to adjust this with vireio?? how? ( i tryed tridef but i could do it)

i dont want to re-print my googles, since i may print them wrong again...

i am connecting the googles screen via hdmi, and this monitor has not physical buttons to move the image to left and right as a normal monitor does...

please help... i have invested so much time with no joy...

best regards
