Windows 10: extended display issues

I have a laptop and using a dock to extend to a 2nd and 3rd monitor. all monitors duplicate fine, but if i choose to extend, monitors 2 and 3 do extend, but they are duplicates of themselves. the computer settings seem to only recognize monitor 2 and 3 as one monitor.

We would like to know more information from your end to know what is the next possible step that we can offer for you to resolve your issue.

• Were you able to get an audio on your extended display before? Or is this the first time that you will set up an extended display with your computer?
• Aside from the HDMI cable, have you tried using VGA cable instead to connect to your extended display?
• Can you verify if you have any audio on your speakers if you are not connected to the extended display?

We look forward to your reply.

 

no audio on extended display

Is your computer’s Operating System updated?

How about your Audio drivers, can you check if it is updated and can support HDMI audio output?

If your answer to those questions are yes, then you can check these steps to setup audio for your extended display:

• Connect your laptop to the extended display using the HDMI cable.
• On the lower right side of your task bar, right click on the Audio icon.
• Select Playback device
• If you don’t see your extended display (T.V) you can right click on a blank space on the Playback tab and select Show Disabled Devices and Show Disconnected Devices.
• One your extended display (T.V) is showing, please check if it is enable.
• Then Select OK.

Do a test and check if the audio is now playing on the extended display, if issue still persists, try to restart your computer without removing the HDMI for both devices.

Let us know how it goes.
