I have 3 Windows devices
1) Surface Pro 7
2) A new Dell Inspiron 15, 5510 with a thunderbolt 4 port
3 A 6 years old Dell Inspiron 15 Signature Edition Laptop
At any given time all devices are powered on but I am only working on one device at a time. All I need to be able to do is to share one monitor, keyboard (USB dongle) and a mouse (USB dongle). Happy to un/plug between devices for easier switching. But if there is a docking station which lets me switch between devices, that will work too. Mostly home/office use, no gaming.
From a recent deal I got the Vavo USB C hub which works with devices 1 and 2 but not with 3 as there are no USB C ports on the 3rd device (only USB A) and its manual clearly says will not work with a USB C - A adapter.
Cheers!
Does your 6 years old Dell Inspiron 15 Signature Edition Laptop have USB3 port? If so, you might just need to get a USB3 cable with Type A (Male) to Type C (Male)and then try to use that docking station
If it is USB 3 port it will work. It it is USB2 then it won't have the bandwidth to output external video
Also found a no name 4 port KVM on Amazon AU for under $80 that will do the trick.
