Windows 10: Plugging a 2nd monitor into my PC tower causes both to lose signal

I have dual monitors but my PC tower only has 1 HDMI port and no VGA port so I bought an HDMI splitter to plug both in. However, when I plug the second monitor into the splitter, both screens turn black and say that they have lost signal. Any ideas how I can use both monitors?

2nd Monitor not recognized- After Fall Creator Update I see "no hdmi signal from your device"

Just downloaded Windows fall creator update and my 2nd monitor won't work. The 2nd monitor says 'no hdmi signal from your device'. Tried unplugging and plugging in again. Drivers seem to look up to date. Any suggestions?

Monitors Lose Signal On Boot


I have 3 Benq xl2720z monitors all using dp.

In the morning I went to turn on my monitors to find out there was no signal in any of them. I then rebooted my computer and when I got to the spinning orb, my computers faded to black in the middle of it and lost signal. I didn't even get to the login screen.

I then decided to try each monitor by themselves starting with the left monitor. this monitor managed to the login and to the desktop. However it still faded to black as if it was about to lose signal in the middle of the spinning orb. However it managed to recover I guess and show the login. The part that I noticed is that it took much less time to normally to get to the login so something is not right.

I then tried the middle monitor. The first try I got to the desktop just to lose signal a second later. The second try I lost signal during the spinning orb.

For the right monitor, I lost signal when I got to the desktop. Didn't bother trying again with it.

Since the left monitor I could get somewhere I decided to go and plug that one in so I could go and write this, however I accidently plugged in the middle monitor but it was idea I did because something new happened.

I got to the login and desktop fine and it never faded to pure black in the middle of the spinning orb. It showed the whole animation but the second one with the blue screen. It also longer to boot up which was how it was suppose to be.

So I no idea what is going on. It all feels random. Can someone help me with this?

I'm going to try rebooting again and see if the middle monitor is fine now and then I'm going to try all 3 together.

EDIT: Tried again with the middle monitor, it booted without issues. Tried again with 3 monitors, it booted to desktop without going to no signal, however the boot was shorter. Is there a reason for Windows 10 to not go to the seconded spinning orb with the blue screen?
