Use
GFXconfig –i
or
pgxconfig –i
to test a resolution before configuring the
console to that resolution.
Methods for Changing the Console
Resolution
The procedures for changing the console resolution described in this appendix
include:
■
EDID Auto-Detect feature
■
output-device
method
■
Video-Mode method
■
Video-Timing method
EDID Auto-Detect Feature for PGX32
If you are using a monitor with DDC2B/EDID protocol, then the default resolution
is determined using the Auto-Detect feature.
With this protocol, the GFX card first checks the Standard Timing Identifiers (taking
the first one supported), then tries to match the Established Timings.
Failing the above method, the card defaults to 1152x900x66.
Note –
The monitor must be turned on prior to booting the system in order for the
PGX32 to communicate with it.
The methods described in this appendix override any information obtained via
EDID.
output-device
Method
It is possible to specify the console resolution of PGX32 card via the
output-
device
environment variable by using the format
screen:rAxBxC
,
where:
A
is the desired horizontal resolution,
B
is the desired vertical resolution, and
C
is the desired refresh rate.
