How to Connect Blu-Ray Player to Projector

In order to connect your Blu-Ray disc or BD player to your projector, you mostly need an HDMI cable and connection. It’s practically the same as connecting a DVD to your projector or your BD to a computer (especially if you have one of those advanced smart projectors on hand).

An HDMI cable should take care of both the HD video stream and the hi-fi audio stream in one port and connection, but it depends on the projector in question. If it’s a legacy or older projector, its HDMI port might exclusively on take in a video feed while the audio feed should be placed elsewhere.

This is especially true of projectors with no built-in speakers. You might need a Bluetooth speaker or a soundbar connection to your source media to fix the lack of sound for vintage projectors.

HDMI Cable Connections and Proper Image Placement

In order to connect your BD player to your projector, you’ll mostly need an HDMI cable of the right speed relative to the kind of HDMI port you have on hand. HDMI is backward compatible but higher quality HDMI specifications will lose features when you use slower HDMI cables for it.

You should also adjust the projector to your screen with the correct or exact throw distance so that the image is squarely on the reflective surface. If keystoning occurs or you have no choice in your projector mounting, you can adjust the screen further with keystone correction, lens shift, and zoom features.

Turn on the Projector and Find the HDMI

When installing the projector, you need to turn it on first. Connect its power cord to the wall outlet then push the on/off button so that you can operate it.

Your projector sometimes comes with a CD, DVD, or BD you can play on your BD player to help you with image setup and placement on the screen so that you won’t have to deal with it manually. Make sure the projector’s air vents aren’t obstructed for good measure.

The projector should be cleaned from time to time to keep dust from destroying it from the inside as well. From there, locate the HDMI connector on both your projector and player.

Plug the HDMI Cable Connectors on the Right Ports

Plug one end of your HDMI cable onto the BD player’s HDMI port, Afterwards, go and plug the other end onto the projector’s own HDMI port. Check the HDMI specifications of both and go with the lowest spec. It’s better if the specs match though (like both are HDMI 2.0 or 2.1).

The higher the resolution of the player and the video projector the faster your HDMI cables should be to deliver 4K Ultra HD or 1080p Full HD. If you were to use a slower cable you’ll end up with a slower connection and a downscaled 4K video that’s now in 720p or lower.

Turn the Blu-ray Disc Player on so that it could finally interface or connect with your projector. Then again, HDMI cables can be plugged into devices even if they’re already turned on from the start. It’s that kind of plug & play tech.

Focus, Tilt, and Adjust the Image or Projection

You should see the Blu-Ray logo or the disc title screen on your BD if you’ve established the connection correctly and already put in a BD inside the player. Make sure the image or projection of your projector is clear by using its focusing ring. Keep turning it until the image is perfectly sharp and decipherable.

The calibration DVD or disc can assist you in testing out your projector. Playing the disc should result in a grid pattern. Do more tweaks and finagling with the projection using the lens adjustment feature of your projector. If the pattern isn’t square, make it square with lens adjustment.

Tilt the lens down if the pattern looks like a pyramid or up if it looks like a diamond. Tilt the lens to the left if the pattern tapers to the left and to the right if it tapers to the right.

Insert a Blu-ray Disc into the Blu-Ray Player

Remove the calibration disc from your player once you’re done with the calibration tests. If you lack a calibration disc, you can finagle the image correction features of your projector manually by trial and error.

At this point, insert a movie or TV show compilation Blu-ray disc or BD into your Blu-Ray disc player or BD player. If you’ve properly established your HDMI connection from the player to the projector, the menu screen of your BD should pop up, allowing you to play it in a straightforward manner.

Troubleshoot If Required

If you’re not getting a signal such that it says “No Signal” and you can’t get a picture out of your Blu-Ray player, you should troubleshoot the connection. Check if the cable is damaged or pinched in any way. Make sure the HDMI connector is also properly connected to the port.

Press the “Source” button on your projector and select “Video”. If your display device has the “Source Search” function, use that to search for the signal. There might be an issue with either the cable or the port.

Hopefully, the ports themselves aren’t damaged or gummed up. If a connection cannot be established, seek professional help.


Connecting your BD player to a movie projector should be fairly straightforward. Just plug & play for the most part. The Blu-Ray disc player is incidentally a player for a propriety standard of disc media instituted by the Sony Corporation a la the Betamax format.

Even though Betamax fell on the wayside against VHS during the recorded tape format wars, the successor to the DVD eventually became the Blu-Ray instead of the HD-DVD thanks in part to the huge popularity of Sony’s PlayStation 3.
