Opi One how to underscan

[psygnosis]

Hi, guys, today I've menaged how to make my opi1 work with armbian.

the problem is that my hdready tv (720p50) has some problem with underscan, the desktop goes off screen so I cannot see the taskbar.

Of course this is a problem of my tv, because I have the same problem when I use it as monitor for my PC, but there I can set the underscan through nvidia setting.

So, How can I set up the overscan/underscan to see all the desktop on 720p? (using h3disp and set 576p doesn't work, I have "no signal" on tv)

thank you in advance

armbianmonitor -u is the first step if you expect some help/attention. Well, prior to this is reading and this should be a result
