Tips For Projecting With Roku

Here are some tips to ensure success:

  • For ceiling mounted projectors, install the Roku nearby so cables can easily run up to the ceiling.
  • Place the Roku out of sight if possible to keep the setup looking clean.
  • For outdoor movie nights, protect the Roku from weather using an enclosure or bring it indoors when not in use.
  • Enable HDMI CEC control to turn on the projector when the Roku powers up.
  • Adjust projection settings for proper geometry and brightness based on screen size.
  • Enable subtitles and descriptive audio for outdoor or noisy environments.

Connecting With HDMI Cable

The most common way to connect a Roku to a projector is using an HDMI cable between the two devices. Here’s how:

  1. Make sure your projector has an open HDMI input. This is typically labeled as HDMI 1, HDMI 2 or similar.
  2. Power off both the Roku and projector if currently on.
  3. Plug your HDMI cable into the HDMI out port on the rear of the Roku.
  4. Connect the other end of the HDMI cable to the HDMI input on the projector.
  5. Power on the projector first and select the correct HDMI input.
  6. Finally turn on the Roku. It should automatically link with the projector.

The Roku interface will now show on the projection screen or surface. Browse apps and play content as normal.

Connecting Roku Wirelessly
