What is the opinion of Reddit about the
TESmart Dual Monitor KVM Switch 4 DisplayPort PCs + 2 DisplayPort Monitors Updated [email protected], Support Cascading for Quad Monitor, HDR 10, HDCP 2.2, (Black)?

My monitor says it supports that but I’ve never been able to get it to work.

cost less than a single one of those boxes.

Overall latency is rarely a big issue with these boxes.
