Read Before Connecting a Computer (Supported Resolutions)
Check the resolutions supported 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 pages. The TV will automatically adjust to the resolution you choose. Note that the
optimal and recommended resolutions are 3840 x 2160 at 60Hz (UHD models) and 7680 x 4320 at 60Hz (Q800T
series or higher). Choosing a resolution not included in the tables can result in a blank screen or just the remote
control sensor turning on. Refer to the user manual of your graphics card for compatible resolutions.
The native resolutions are 3840 x 2160 at 60 Hz (UHD models) and 7680 x 4320 at 60Hz (Q800T series or higher) with the
Input Signal Plus set to On. The native resolution is 3840 x 2160 at 30 Hz with the Input Signal Plus set to Off.
