h3disp Access denied(Hdmi to Dvi not working)?

[NeillEvans]

Guys please help me.

My orange pi one with Armbian installed and running Pi Hole. The HDMI Output is not working, And when I try to enter this command h3disp [-h/-H] -m [video mode] [-d] [-c [0-2]  it say access denied. 

 

My point is there's no output this play on my device. 

 

I hope someone understand me and help me thank you.

I don't know what this command is, but did you try putting sudo in front of it?  Or su command to become root?
