Check the resolutions supported for PC input signals.
When you connect your Projector 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 Projector will automatically adjust to the resolution you choose.
Note that the optimal and recommended resolutions are 3840 x 2160 at 60 Hz and 1920 x 1080 at 60 Hz. 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 resolution is 3840 x 2160 at 60 Hz 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.
