If the monitor does not "sync up" at the default console
resolution, it may be necessary to choose a different console
resolution.
A.1.2 Guidelines for Changing the Console
Resolution
There are some general guidelines to follow when changing the
default console resolutions. They are as follows:
•
By default, all console resolutions will automatically be set to
8-bit mode.
•
It is recommended that you use mkoconfig –i to test a
resolution before configuring the console to that resolution.
•
Digital output on the DVI port is limited to 1280x1024@60.
A.1.3 EDID Auto-Detect Feature
Auto-Detect is limited to 1280x1024@60 on the DVI port only. If
overrides are used to exceed this limit, only analog signals will
be produced by the DVI port. Digital signals will be turned off.
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 400 card first checks the Established
Timing Identifiers (taking the first one supported) then tries to
match the Standard Timings.
NOTE: The monitor must be turned ON prior to booting the
system in order for the GFX 400 card to communicate with it.
Some adapters and cables may block this signal.
