Make sure that the display resolution and refresh rate settings you have selected are

supported by the monitor you have connected.

7.1.3 There are screen defects.

Make sure your monitor supports the resolution and horizontal (kHz) and vertical (Hz)

refresh rates as required by the graphics card. Check your current resolution, refresh

rate, and color depth settings in the Settings and Monitor tabs in your Display

Properties dialog.

Caution:

Ensure that both the graphics card and monitor support the resolution and refresh

rates you select. Incompatible resolution/refresh rate selection may result in

monitor damage. Refer to your monitor's documentation for recommended

resolutions and refresh rates.

7.1.4 The screen image is off-center or there are odd colors.

Try adjusting the brightness, sharpness, contrast, and color balance controls of your

monitor.

Try adjusting the centering and positioning controls of your monitor to position the

picture on the screen.

Set the monitor's RGB inputs (and sync switches, if this option is available) to 75 Ohms,

with the sync set to external.

DFP monitor users: Make sure that the DVI plug of your monitor data cable is digital-

only (DVI-D), not integrated analog/digital (DVI-I). Refer to your monitor's

documentation and contact your supplier or the manufacturer of the DFP monitor for

information on how to obtain a suitable data cable plug.

7.1.5 The operating system warns that the graphics card isn't properly

configured.

Make sure that the display resolution and refresh rate settings you have selected are

supported by the monitor you have connected.

Check the driver installation and make sure that all software is correctly loaded

corresponding to your operating system and applications.

Reinstall the drivers for your graphics card.

7.1.6 There are bus address or interrupt conflicts.

Make sure that the I/O and memory addresses reserved for the graphics board are

not used by other hardware devices. The integrated on-board VGA controller of your

AMD FirePro card uses the following addresses (hex):

•

I/O Address: Standard VGA I/O: 3B0-3DF

•

Memory Addresses: Video RAM: A000-BFFF, Video ROM: C000-C7FF
