Reason for Changing the Console Resolution
Normally, the default console resolution is sufficient for most users. If the monitor
does not sync up at the default console resolution, it might be necessary to choose a
different console resolution.
Guidelines for Changing the Console Resolution
By default, all console resolutions are set to 24-bit mode. Use
fbconfig -i
to test a
resolution before configuring the console to that resolution.

60 on the digital video 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 Sun XVR-200
graphics accelerator first checks the Established Timing Identifiers (taking the first
one supported) then tries to match the Standard Timings.
Note –
The monitor must be powered up and turned on prior to booting the system
in order for the Sun XVR-200 graphics accelerator to communicate with it. Some
adapters and cables might block this signal.
If the Auto-Detect feature fails, the card will default to 1024

75 Hz.
Note –
The other methods described in this appendix override any information
obtained through EDID.
