At the top left is a 3D SYNCHRO terminal to connect the optional 3D Synchro Emitter. Next, are a pair of HDMI 2.0b (HDCP 2.2) inputs. Both HDMI inputs are 18Gbps, so they support 4K HDR up to 60fps.
There is also a traditional serial RS-232C port (DB9 connector) for “old school” command and control. Command and control can also be done via HDMI, etc. To the right is the USB terminal used for service and firmware updates. Finally, there is the RJ-45 jack for standard Ethernet networking and a single12V trigger output which can be used to control a screen, the sled of an anamorphic lens or motorized shades.
As with most newer home theater projectors, many of the older “legacy” type inputs are gone, including a lack of VGA input or component video and S-Video.
Since this a “serious” home theater projector, you will not find an internal speaker or audio outputs. This type of projector normally does not have multiple sources connected directly to it since a receiver is usually utilized for AV switching. The DLA-RS3000 is also not equipped with internal streaming services which negates the need for audio outputs. In a home theater, audio is normally handled by an A/V receiver and speakers, so the lack of audio features is not a big deal.
