Just fyi - i bought something like this marketed as "triple display" - just be aware that if you use all three, your built in laptop screen will likely turn off given processing limitations - so NOT 3 *additional* screens + 1 laptop screen = 4 total. No, It's 3 *total* no matter what. At least this is the case with lenovo x240
1) This is not a KVM switch
2) This is not a Thunderbolt dock. MacOS doesn't support MST (Multi-Stream Transport) over USB - i.e. you can only have the same mirrored image across all external monitors.

P.S. you will be looking for something like this (but it's not widely available for purchase yet): https://www.ssi.com.tw/product/kv...4-kvm-dock
Lolol it was me that asked in that thread too. Didn't realize it was the same dock

Has anyone had good experience using this with other brands of l laptops? Specifically Lenovo? Just needs a USB 3.O/thunderbolt port right? The extra card is built into the docking station? Any drivers needed for non dell device?

If you get this, be sure to update the drivers/firmware. They are available on Dell's support site.
