Two monitors can't be on at once with an hdmi switch
I have a two monitor setup at home and have had it working for some time now. I do a lot of work from home and plug my work laptop in to my existing monitors so I can have more room to move around the large amount of windows I constantly have open. Because of this, I have had to dig around behind my monitors in order to free the hdmi cables and change the display computer, so I recently picked up some Fosmon HDMI 3x1 pigtail switches. This is, however, where the issue lies. While I have one switch plugged in, everything works perfectly fine. As soon as I plug the second one in, the second screen goes blank. However, if I unplug the first screen, the second screen will go on correctly and take the first screen's place. The OS detects that there is a monitor there, it will just refuse to send any display data to it so the monitor goes into power saving mode. If I switch the two pigtail switches, the switch that was attached first seems to continue to work but the original working monitor now turns off with the second-attached switch. If anyone has any idea what the next diagnostic step would be for this, please let me know as I am unsure as to what may be causing this other than a defective cable (which seems to be working if it is the only one plugged in).
OS = Windows 10
Graphics Card = GTX 770
Monitors = Both 24", one Asus, one Dell
If any other specs would be useful, let me know. I can always through a large diag file in here, but I wasn't sure if it would be necessary.
