How can I connect the projector to a computer?

Connect the analogue RGB signal output of the computer to the HD D-Sub 15-pin terminal on the projector.
Or, connect the digital signal output from the HDMI terminal on the computer to the HDMI terminal on the projector.
However, your computer must be outputting the signals listed under Acceptable Input Signals in the Operating Instructions of the projector.

Check the Operating Instructions of each model as follows.
 1. Access https://pro.sony -> Click “Professional Products” at the top -> click “Projectors” -> Select your model in the Projectors page to open the page for the given projector.
 2.  Click “Resources” at the top of the projector’s page -> Click “Manuals” under “Support”in the “Resources and downloads” section.
 3. Click the download button on the right of “Operating Instructions” to see the Operating Instructions pdf file.
