If you are experiencing problems using HDMI input:
- Confirm the HDMI input is selected.
- Plug in the monitor first, and then turn on the PC.
- Replace the HDMI cable, sometimes a cable may go bad.
- Try another signal type if available for example: VGA, DVI, DisplayPort.
- Test the monitor on a different computer with a HDMI port to make sure that it is not the video card.
Noted:
- Make sure that the power cable is connected to the back of the monitor and that the power button is turned on. Double check power strip if necessary.
- Verify that the computer is turned on and booted up.
- Make sure the video cable supplied with the panel is tightly secured to the video card in the computer and to the back of the monitor.
- If available, try another video connection. If your monitor has a different signal type, try it to see if a different connection is able to get a signal.
- If your projector is connected to a Laptop or Notebook computer, or this is a secondary display, the video output settings on your operating system may be disabled. Confirm that the display settings/properties on the operating system are configured correctly. To get to the Windows display properties, single right click on an empty spot on the Windows desktop and select Properties.
- Connect the projector to a different computer system (if available) to see if the issue is with the video card or the monitor. Check the user's guide to see if any special conversion connector or adapter is required for proper signal continuity between the video card and the projector.
