Hanns G HW191D
max reso
note useless for super common 1080P resol.
the PC if smarter would scan the old monitor and set to top of my list and work. VESA DDC2B<< Plug and Pray.
that hanns was sold at vga only and vga/dvi
if yours is 2 ports
see page 14 in your manual
HW191D:
Select the ?INPUT SETTING? option to change between analog
(VGA) or Digital (DVI) source. Enter the option and select
Analog or Digital.
[Dual input mode optional
the PC (secret) in the
BIOS has rule on
onboard video ports
and PCI-express cards how they work
most today are fixed at auto selection. (video, but...)
so if PCI card is there it wins every time and local VGA goes dead
in the olden days 2000 , we had to set it there to what we wanted.
my wild guess:
1: desktop has video card
2:laptop you forgot to RTM and pust the FN+xx kes.
that FN key, well show,( vga, LCD local , auto , both)
see how that works, RTM read the secret PC manaul.
some PCs (desk) can have 2 vga jacks ,1 card, and main on case)
the card always wins
