I'm considering buying some kind of thunderbolt 3 dock to drive 2 1440p displays.
Since cables included with the dock are really short - does anyone now if I can use 20Gbps thunderbolt 3 cable to connect such dock?
I'm not sure what is the real difference between 20Gbps and 40Gbps cables besides pure bandwitdh (obviously) and price...
I can get 20Gbps 3A cable for 20-30 dollars where 40Gbps start at around 70
 
with 40Gbps you can drive 2 4K monitors, so with 20Gbps you should drive 2 1440p displays
