Using a 30" monitor at 2560 x 1600 with VirtualRPC was not fun as the Display Configuration utility limits the selectable display to only 2048 x 1534.
The alternative was to write specific MDF scripts for new modes.
I have added three (3) new display modes to the default VirtualAcorn (VRPC-SE) monitor file to make use of the large 30" screen at display resolutions of 2560 x 1600.
The definitions are as follows:
Code:
#-------------- start ----------------------
# For full screen display mode outside Windows desktop
# 2560 x 1600 (51hz)
startmode
mode_name:2560x1600 FullScrn
x_res:2560
y_res:1600
pixel_rate:214000
h_timings:10,10,16,2560,0,0
v_timings:10,0,0,1600,0,0
sync_pol:0
endmode
# For display in the Windows desktop
# 2560 x 1600 (51hz)
startmode
mode_name:2560x1600 FullDTP
x_res:2560
y_res:1470
pixel_rate:197000
h_timings:10,10,16,2560,0,0
v_timings:10,0,0,1470,0,0
sync_pol:0
endmode
# For display in the Windows desktop when
# the gadget bar is also displayed
# 2560 x 1600 (51hz)
startmode
mode_name:2560x1600 DTPGBar
x_res:2400
y_res:1470
pixel_rate:184000
h_timings:10,10,16,2400,0,0
v_timings:10,0,0,1470,0,0
sync_pol:0
endmode
#-------------- End ----------------------
The first mode is a Full Screen mode 2560 x 1600 for display outside the Windows desktop.
The 2nd mode is a display setting for use when in the Windows desktop as it adjusts the vertical display for the height of the Windows Taskbar.
The 3rd mode is a display setting for use when in the Windows desktop and adjusts for both the Windows Taskbar and Gadget Bar in Windows Vista.
The VRPC-SE monitor definition file is located in the following directory:
HostFS::HardDisc4.$.!Boot.Resources.Configure.Monitors.VirtualAcorn
it is a text file and you can add the above 3 definitions to the end of the file just before the last line reading #End.
With the above resolutions,
as a default, the system will limit you to 32K colours.
Hope someone may find the above helpful.
Cheers.
