If you're thinking about the monitor as being useable with a PC, it depends
on which type it is. The lower-resolution type (I once had one) will work
at 1024x768 if you connect a resistor of about 500 ohms between the
composite blanking signal on the "application connector" to the GREEN output
from the card. This will impose the composite blanking beneath the GREEN
video, and bias the GREEN up by about enough to make the composite blanking
look like a composite sync, since it's of the right frequency. The GREEN
input is usually AC coupled at the monitor, and terminated to ground through
75 ohms. This is worth a try, but may not work on all card-monitor
combinations.
It will of course not work at all until you load the 1kx768 driver, which
will only happen when the hi-res GUI is loaded.
