Very very few laptops drive 3 monitors. Most will drive the LCD and one external. As Dell has some thousand models to date, you must ask Dell if this laptop does 3 displays (LCD plus two.)
-> Splitters do not make independent displays. They only split the SAME video to two places. This is rarely what folk want.
So I recently started to work on my r/battlestation. I currently have a Sony Vaio PCG-71312L laptop running windows 10 that I’m trying to connect to both an older Dell monitor, and a smaller Sony TV.
The laptop has an HDMI port, as well as a VGA port. Both the monitor and the TV have all the necessary ports (VGA, DVI, and HDMI). I have hooked my MacBook Air up to the TV by itself and used it as an extended desktop so I know it works. But, when I try hooking my laptop into the the dell, and the dell into TV I end up with the Dell as an extended screen, and the TV only mirroring the second screen.
I have tried a range of ways to connect the three. I have tried using a HDMI to VGA adapter, with a VGA chord running to the dell, a VGA splitter in the dell, receiving the laptop VGA and going to the TV.
I have tried plugging the VGA splitter directly into the laptop and feeding 2 VGA cables to the monitors. No matter which way it won’t identify the TV as being connected.
The parts I have readily available are: 2 VGA cables, one DVI cable (although I’ll pick up an extra if necessary), 4 HDMI chords, a VGA splitter, and a VGA to HDMI adapter.
Is there anyway I can get the laptop to identify the TV as a third monitor? If not what parts will I need? I’m hoping to not have to spend $100 on a Display link quite yet unless it’s my only option.
