Sabrent SB-TB4K Thunderbolt 4 KVM Switch Review
Sabrent SB-TB4K Thunderbolt 4 KVM switch lets 2 computers share a display via DisplayPort Alt Mode, up to 8K@60Hz on a single monitor or 4K@60Hz on two, with 3x TB4 and 4x USB-A 10Gbps ports and 60W power delivery.
A Thunderbolt 4 hub-and-KVM combo: 3 TB4 ports plus 4 fast USB-A ports let two computers share one high-resolution display, with 60W of charging passed through the built-in power adapter.
Overview
The SB-TB4K pairs Thunderbolt 4's 40Gbps bandwidth with KVM switching, giving two computers shared access to a single 8K-capable display (or two 4K displays) plus 4 fast USB-A ports, powered by an included 60W adapter.
Our verdict
Reviewed by Burooj Alam. Rated by us, not by users.
Expert rating7.1 / 10
A well-specced Thunderbolt 4 KVM/hub combo from a value-focused accessory brand; strong single-display resolution headroom, though Sabrent's KVM lineup lacks the track record of dedicated KVM specialists.
Best for
- Two computers sharing one high-resolution (up to 8K) Thunderbolt 4 display
- Users who also want extra fast USB-A ports alongside KVM switching
- Thunderbolt 4 setups needing 40Gbps bandwidth
Not for
- Thunderbolt 5 setups wanting native TB5 bandwidth
- Simultaneous 8K on two displays at once
- Users needing more than 60W of pass-through charging
