Setting the display resolution

• Set the refresh rate of your TV or monitor to less than 60 Hz to avoid damage

to your TV or monitor.

• If no image is displayed on the TV or monitor after setting a new refresh rate,

turn off your TV or monitor and wait for a moment before restarting.

• When connecting to a TV, please select the TV’s appropriate input channel.
• Lenovo recommends connecting the computer to a monitor using the VGA or

HDMI video connector.

• It is possible to connect the computer to a TV using the VGA or HDMI video

connector, but Lenovo is unable to guarantee that this will work effectively.
After the computer is connected and is operating normally, if a blank screen or
no image is displayed on the TV, this may be a problem with the TV settings.
Please consult with your TV supplier.
