If the cable is not damaged, check the projector input settings and computer display settings, update graphics card drivers, and inspect your projector HDMI port. When your Epson Projector displays a ‘ No Signal’ message when using HDMI as input, first inspect the HDMI cable. In that case, I would recommend getting in touch with Epson’s official support. If the new cable works without a ‘no signal’ error message, then it means your projector HDMI port is faulty. If that does not work as well, test your laptop with another projector or monitor using HDMI. If your projector has multiple HDMI ports, try using the other one. If none of the above methods work, maybe the issue is with your Epson Projector port. Once your graphics card drivers are updated, restart your computer for changes to take effect. Select Search automatically for the driver option. Right-click on your display driver and choose Update Driver. Make sure youre plugging in the right part of the cable to the right input. Connect the other end of the cable to the video adapter. Make sure that your TV, monitor, or projector is turned on. You can open it by typing devmgmt.msc command in Windows Run. When youre ready, heres how to set it up: Plug one end of the video cable into the port on the external screen. To update graphics card drivers in Windows 10 or Windows 11, open Device Manager. Another quick workaround is to update your computer GPU drivers.
