Makes sense. One of the HDMI is the "computer" input.
It is a multi-scan port which handles VESA resolutions.

The other HDMI are HD/SD ports and take 1920x1080 or
whatever the SD value is. They don't have the same details
as the "computer" one. They should support fewer resolutions.

Usually, the manual would have a short section on the computer
one and mention it supports 640x480, 800x600 ... 1366x768 ... 3840x2160.
Perhaps it won't bother to mention the HDCP aspect, but it really
should, as this issue of getting something other than a black screen
has come up before.
