You can add up to two external monitors to the TS4 as long as your computer’s
Thunderbolt ports support dual displays. M1 Pro, M1 Max, Intel based Macs, Thunderbolt
4, and Thunderbolt 3 PCs support up to dual displays. Some early Thunderbolt 3 PCs do
not support dual displays. Check if your Thunderbolt 3 PC supports dual displays. Users
on original Apple M1 computers, or on USB-C PCs can only connect a single display to the
TS4. In addation to the dual monitor support, TS4 can support an external monitor with
higher refresh rate showing below.
