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 3840 x 2160 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.
