Hi Kevin,

(In reply to Kevin Brace from comment #284)
> Does VGA at least work if you use a DVI to VGA adapter for Wyse V90LE?
Not working for VGA port(I use a DVI-I->VGA converter) now. Attached is the
log. It seems VT1632 probing is still working even VGA port is used from DVI-I.
And there is no EDID probe process for VGA port.

What does Digital Video Port be used for?

Thanks,
Frank
