How to do I connect 3 external monitors to my surface pro 7?

Hello,

(Quad screen: i.e. 4 externals + tablet screen) I've a Surface Pro 7 / 7i / 64 - system and have found a connecter that works. NOTE - Driver must first be installed (I was so excited I didn't read those instructions,... Good news my tablet was still new so i just did a factory reset). I found a 4 to 1 (4 HDMI to 1 USB C on Amazon. Made by: J5 create/ model = (JCA366) - Amazon.com: j5create USB-C to 4 Port HDMI Adapter Hub- Multi Monitor Splitter - Support 4 1080p 60Hz Displays - Compatible with Type-C MacBook and Windows Laptop (JCA366) : Electronics . ... and yes the 'J5 Create'(JCA366) does work.

Question. I've a Surface Laptop 3 Model VAC-00022. I've a Surface Dock 2 that displays 2 external monitors correctly. I'm hoping to use the USB-C from the laptop itself to display a 3rd monitor. I tried buying a USB-C to HDMI cable but that doesn't work. That probably doesn't work because the other 2 monitors are USB-C to HDMI from the Surface Dock 2 itself.

Does anyone know how to get a 3rd external monitor, so a total of 4 screens (with the laptop screen working as well)?

I think it may have to do with the dock itself. I have the newer surface dock with 4 USB C ports (2 in the front 2 in the back) and cannot get a 3rd monitor to work with my surface pro 7 (3 monitors + the surface itself). I work in an office and 3 of my co-workers have surface pro 7 set ups with 3 or 4 external monitors. They all have the older dock that has 2 mini display ports in the back and 2 USB 3.0 ports in the front. This is the only thing I can think of that may be causing the issue because otherwise our set ups are the same but I cannot get the 3rd monitor to work.

Which USB Video Cards did you use? Looking to just ensure compatibility.

It supports 3 monitors only including Surface's monitor.

If you want to use the fourth monitor, you can buy windows wireless wifi adapter:

Connect the fourth monitor through wifi.
