graphics card BIOS not obtained from Lenovo to refresh or upgrade the existing BIOS. Otherwise, the
graphics card may not work properly, causing you a lot of unnecessary hassle.
• Before adjusting the display mode, read the instructions for the display device to confirm that it can
support the new refresh rate and resolution. If you cannot confirm that your display supports the desired
display mode, you can consult the technical support department of Lenovo.
• In a DOS environment, this graphics card does not support simultaneous output to two display devices.
• In expanded display mode, if you use certain playback software to play DVDs, the video will only be
output on the main display. Therefore, to avoid inconvenience, adjust the primary/secondary attributes of
the displays before playing a DVD.
• The settings interface of the multi-display output function may differ slightly with different driver versions
and operating systems.
