Computer Connection Precautions

•When you connect your TV to a computer, set the computer's video card to one of the standard resolutions listed
in the tables below or on the next page. The TV will automatically adjust to the resolution you choose. Note that the
optimal and recommended resolution is 1920 x1080.
•Choosing a resolution not included in the tables can result in a blank screen or just the power indicator turning on.
Refer to the user manual of your graphics card for compatible resolutions.
