Hi, I have a Tektronics display 21HV8SA, similar to Viewsonic G810 /
Panasonix TX-D2162.
There is four buttons at the front (writen: 1 < > 2) + on/off button.
With the four buttons, you can tune the brightness, contrast, colors,
select the input ...
What has append, I've no idea, but when I push a button, I get a lock
on the screen and I'm stuck there, no way to change my inputs!
Any idea? I've tried to push all the buttons but I always get that lock
on the screen.
