How to Fix Epson Projector “No Signal” Error on HDMI Input

If your Epson projector is showing a No Signal error, it’s mostly because the incorrect input source is selected, or damaged HDMI cable.

Sometimes this issue can also caused by a malfunctioning projector port.

To fix it, first check the input source in projector’s settings.

To do that, press the Source Search button on your Epson projector remote.

Usually when you press it, your projector will automatically search for connected sources and display it.

However, if you have multiple inputs, the projector will display a menu to select input source from. See the screenshot below:

If your Epson projector comes with 2 HDMI input, note the port number you have plugged the HDMI cable to and then select the same in settings.

Select the HDMI source in using the remote control and press Enter.

You have selected the correct input source, but still your Epson projector display No Signal error? The next step is to reset the projector connections. Here’s how to do that:

  1. Turn off your projector and your computer or whatever input source you are using.
  2. Unplug the projector from power source.
  3. Now, disconnect the video cable (HDMI) from the project and then press its Power button for 15 seconds.
  4. Wait for 1 minute and then plug the projector back in.
  5. Turn it on first, and then connect your computer to the projector.

Still having trouble? Check the HDMI cable, the projector input settings, computer display settings, and the projector HDMI port.

HDMI Cable

Your Epson projector might be working fine, but if the HDMI cable you are using is faulty or damaged, it won’t transmit the data to the projector.

Inspect the HDMI cable for any physical damage.

You can also try swapping the ends of HDMI cable.

If you have a spare HDMI cable, use that. If it solves the issue, then the problem was with your HDMI cable.

Check Display Setting on your Computer

If you are using your laptop as an input device, make sure you have selected the external monitor in the settings.

Instructions for PC

  1. Press and hold the Windows Key and P button and then click on the Duplicate option.

Alternatively, you can right-click on the empty area on the desktop, and then select the Display settings option.

  1. Click on Extend these display.

Instructions for Mac

  1. Open System Preferences and select Display.
  1. Select your Epson Projector in the left side and then click on menu next to Use as: option. Select Extended display option.
  1. If this does not work, select Mirror for Built-in Retina Display option. See the screenshot below:

Projector HDMI Port

If none of the above methods work, maybe the issue is with your Epson Projector port.

If your projector has multiple HDMI ports, try using the other one. If that does not work as well, test your laptop with another projector or monitor using HDMI.

If the new cable works without a ‘no signal’ error message, then it means your projector HDMI port is faulty. In that case, I would recommend getting in touch with Epson’s official support.
