I'm a karaoke DJ at a small bar and need the song lyrics to appear on two TVs. The TVs are mounted back-to-back in the middle of the room, with one facing the stage and the other facing the back of the room. The lyrics currently display correctly on the first TV. I connected the computer's HDMI output to an HDMI splitter, then connected one HDMI cable from each splitter output to the TVs. However, the computer only shows its main display and doesn't seem to recognize the splitter correctly. Do I need different hardware or a specific setting to duplicate the display on both TVs?

First, confirm the computer’s HDMI cable is connected to the splitter’s input and that each TV is connected to an output. Also make sure both TVs are set to the correct HDMI input. If both TVs work when connected directly to the computer, the splitter is probably the issue. Some TVs and computers simply don’t negotiate properly with certain splitters, so a different powered HDMI splitter may fix it.
I went through those checks and both TVs work individually. It seems like the computer and this particular splitter just aren’t communicating correctly.
