Read Before Connecting a Computer (Supported Resolutions)
Check the supported resolution for PC input signals.
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 x 1080 at 60 Hz. 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.
