Dual Display for Photon

Hi,
I have managed to get two graphics card drivers working in Photon.
However, I still need to configure the Photon event space such that it will
show one continuous work sapce across two physical monitors. I have tried
using the -o option to the graphics driver, I that I get is the background
image being split into two, with half the background in each.

I have set the both graphics to a resolution of 800x400x8. Just
wondering if it is possible to configure the event space such that I can
have a 400x400 resolution on each of the physical monitors (ie. 1 logical
screen across two physical monitors).

Thanks

Jason

The -o option is the correct option to cause an offset from
the default. I use this and it works. Why don’t you
post the command line or trap file line that you are using.

This is the command line in the trap file:

Hydra.ms -S -i0x103 -s0x0000,0x0078;Hydra.ms -S -i0x103 -s0x0000,0x0098 -nqn
x/crt98;
Pg.flat -HC0x00000098 -PX -HNqnx/crt98 -g800x600 -o800 -A0xDC000000,
0x200000 -WB800;
Pg.flat -HC0x00000078 -PX -HNqnx/crt -g800x600 -A0xE1000000,0x200000 -WB800;
#800,600,8,100,1,flat - SVGA 256 color

I understand that the -o option is used for the offset, but I need to have a
big enough logical screen to occupy both the physical screens. If I run the
command above, all that I got half the logical screen on Monitor 1 and the
other half on Monitor 2. What I need to know is how to set the logical
screen with a size of 1600x600 so that it will fill up both the monitors.

Thanks

Well you lost me here. What do you mean by the “logical” screen?
The Photon space is 64K x 64K, and the screens are placed
somewhere within it. From your statements, one screen
is covering the left half of a 1600x600 area, and the
other the right half. But you say that isn’t what you
want.

Do you want both screen to show the same 1600x600 area?

It sounds like you already have this working.

Your backdrop image does not get automatically tiled or scaled to fit
your ‘virtual’ screen, so if it’s half on one screen and half on the other,
then your ‘virtual’ screen size already spans both monitors.
