The TurboGX/TurboGXplus card uses the sense code bus to identify the
monitor resolution and refresh rate for the monitor connected (see Table C-3
for a detailed description.) The sense code bus exists on the monitor cable and
is driven by the monitor.
While most monitors and refresh rate combinations are supported by the sense
bus, the following monitors are not supported.
1024 x 768 @ 70 Hz (TurboGXplus)
1280 x 1024 @ 67 Hz (TurboGXplus)
These resolutions and refresh rates are defined using the
setenv
command.
If you currently have a monitor that supports one of these resolutions and wish
to use it, read the following section for instructions on how to change the
resolution and refresh rate.
If you are upgrading a GXplus card with a TurboGXplus card, please follow
the instructions in the following section.
The GXplus card ignored the sense code and defaulted to 1280 x 1024 @ 67 Hz
as the resolution and refresh rate.
Since the TurboGXplus card does use the sense code, your monitor will first
boot up at 1152 x 900 @ 76 Hz. To set your monitor to boot at 1280 x 1024 @ 67
Hz as the default, refer to the next section for detailed instructions.
