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.
