When you attach an external monitor to the Enhanced Video model computer
and set the following video modes, you might see some interference or low
screen resolution in the overlay window of the external monitor:
800×600 (resolution) and 16,777,216 (color depth)
1024×768 and 256
1024×768 and 65,536
1280×1024 and 256
To fix this, change the following settings using the ThinkPad Features program:
1. Change the refresh rate; then check whether the monitor screen is
corrected. If the problem persists, go to step 2.
2. Change the color depth. Restart the computer; then check whether the
monitor screen is corrected. If the problem persists, go to step 3.
3. Change the screen resolution. Restart the computer; then check whether
the monitor screen is corrected.
Verify that the operating systems and application programs have been installed
and configured correctly.
If so, have the computer serviced.
Even if you selected television output, whenever you turn on the computer, its
output is always displayed first on the LCD. Use the Fn+F7 keys to display
output on the television.
