Have you checked if the third monitor is recognized by the laptop?

Customer Replay

I have display on the laptop and one monitor
on the tool bar on the bottom it has 3 desktops, but when I go to the settings it only shows 2

So when you go to the Display settings, it does not recognize the third monitor, right?

Customer Replay


Does the monitor show the "no signal" message?

Customer Replay

I don't think so, just black

I'm sorry, do you mean that your monitor shows the "HDMI" message?

Customer Replay


Does your laptop have two HDMI ports?

Customer Replay
