If you are using a monitor with DDC2B/EDID protocol, the default resolution will be 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 will default to 1152 x 900 x 66.
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 will override any information obtained via EDID.
