Check that your source device’s HDMI output and the projector’s HDMI input support the same video resolution and formats, such as 4K or HDR when needed. If the signal passes through an AV receiver or switch, confirm it supports those same formats and that the HDMI cables suit the signal path.

Compare an HDMI projector’s native resolution, brightness in lumens, and HDR support, choosing levels that suit the content, screen size, and room lighting. Also check which HDR formats it supports and confirm that your source device can output them.

For HDMI projectors, placement depends on the selected model’s throw distance, zoom range, and lens-shift options, which affect how large and centered the image can be from a given location. Choose a screen size and aspect ratio that suit the room’s available depth, seating distance, and ambient light.

In HDMI projectors, LED models use light-emitting diodes as their light source, while laser models use a laser light source. Compare each projector’s stated brightness, resolution, and intended use, since models with either source can suit different viewing needs.
