Extending my screen to three TV displays

Hi! So here’s my issue: my church just got 3 TVs to use for worship lyrics/announcements/etc. We got two of them first last week and they worked perfectly! We connected them to an HDMI splitter and
then the splitter to the computer. I extended the computer’s display to show the lyrics on the TV while I managed our live stream on the computer and everything went smooth. Then this week we got the third one in and tried to connect it to the splitter. We
assumed it would just function like the other two. It did not. When all three TVs are set to the same HDMI input the third TV overrides the other two so that the extended display only shows on it and the other two TVs just say "no input". When the third one
was set to a different HDMI than the other two they all showed the lyrics but I could not extend the display so that I can still use the computer while the lyrics are up. It was just showing my computer display so when I tried to switch tabs to check the stream
it showed everything I was doing on the TVs. We need to be able to have the lyrics extended to the three TVs and also be able to check on our live stream on the computer without it showing up on the screens. Like I said, we were able to do that with the two
TVs but when we added the third it messed it all up. We are desperate to get some help soon! Thanks in advance for any advice you have!

 

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.
