[parisc-linux] HP1825 and PCI Vis-EG at 1600x1200

[Grant Grundler]

I just recently got an HP 1825 Flat panel display.
The documentation says the panel supports 1600x1200 resolution
via analog (not DVI) input at 75Khz Hsync, 60Hz refresh (Vsync).

Anyone already know if PCI Vis-EG card can output that?
If so how? Maybe some sort of custom "mode line" in PDC?
I'm looking for concrete steps, not speculation.

I'll hunt a bit more on the internet since I'm pretty sure
I've seen some of the HP parisc workstations allow for
a "custom" video output but don't know if Vis-EG allows
that or where the steps to do it are described.

thanks,
grant

I tried 1600x1200 @ 75Hz on a NEC LCD.  However, I found that the
redraw time with the VIS-EG was too long for my taste.  I settled
for 1280x1024 @ 75 Hz.

The C3k manual describes the commands needed to the Vis-EG 
to its predefined modes.

If I recall, there is a line in the list of settings for the
Vis-EG for user defined settings.  However, I couldn'd figure
out how to set them.

Yup, that's exactly what I was looking for.
I've seen that once upon a time but it might have been
on an HP internal website for a different card.
My fear is I have to run HPUX and "setmon" to get the custom settings.

Anyway, I gave up on this since it looks the manual for the
"HP 1825" really only supports 1280x1024 and the manual is
derived or shared with the "HP 2025" (20") flat panel display.
Thus the comment about 1600x1200 probably only applies to the 20" display.
