JY821 / A closer look

Find the right place for it.

Choose JY821 for a setup that usually stays in one place. Two HDMI inputs, two USB ports and a LAN port give you options for connecting your own sources and network.

01 / Your home theater

Find its place. Refine the picture.

Set JY821 on a stable tabletop with the lens aimed toward your screen. Autofocus and automatic image correction help with the finishing adjustments once the projector is in position.

Keep cables and ventilation in mind when choosing the spot. If you plan to use a mount, check the requirements for your exact unit and bracket first.

02 / Built-in sound

Start with the speakers already inside.

JY821 includes 36W Dolby Audio, giving you a built-in sound option for your home theater setup. Try a familiar scene from your usual seat and adjust the volume for the room.

If you prefer a separate sound system, check the connection and audio settings on both devices before starting a film.

03 / Your connected setup

Keep your sources close by.

Two HDMI inputs, two USB ports and a LAN connection give you ways to build a setup around the devices you use. Plan where each cable will run before placing the projector against furniture or on a shelf.

Use a compatible source and cable, select the matching input and leave enough slack to adjust the projector without pulling on its ports.
