Four-Display USB-C MST Adapter for Windows

The Cable Matters 201099 adapter adds up to four external monitors from a single USB-C port on Windows laptops. It delivers 8K at 60 Hz over DisplayPort 2.1 or 8K at 30 Hz over HDMI 2.1 on a single screen. Multi-display modes reach 4K at 120 Hz on two displays and 4K at 60 Hz on three or four displays with DSC 1.2 enabled.

140 W Power Delivery and Silent Operation

The unit draws power through a 140 W USB-C PD pass-through port to charge the host laptop while driving all connected screens. No fan is present, so operation is completely silent. The compact plastic enclosure measures 1.9 cm by 13 cm by 14.9 cm and weighs 0.11 kg.

Replaces Single-Port Dongles and Docking Stations

This adapter replaces basic single-video dongles when a user needs three or four simultaneous displays. It also replaces larger docking stations for workers who only need video expansion plus charging. The jump is worth it when the host supports Thunderbolt 4, USB4 or Thunderbolt 5 and runs Windows.

Questions about this item

How do I install the 201099 adapter and which step is commonly missed?

Connect the USB-C cable to a Thunderbolt 4 or USB4 port that supports video output, attach up to four displays via the two DisplayPort 2.1 and two HDMI 2.1 ports, then connect the 140W PD charger to the adapter's power input. The step often missed is verifying the host port actually carries a video signal — many USB-C ports are data-only.

What maintenance or replacement will the 201099 adapter need over time?

No scheduled maintenance is required. Keep the plastic housing vents clear of dust so the 0.11 kg unit stays cool during sustained 4K@120Hz dual or 4K@60Hz quad operation. If the USB-C tether or any video cable frays, replace that cable; the adapter itself has no user-serviceable parts.

What limit appears first when driving four 4K@60Hz displays continuously?

Thermal throttling is the first bottleneck. The compact 1.9 x 13 x 14.9 cm plastic enclosure dissipates heat from the MST controller and 140W power delivery, so prolonged quad-display loads at 60Hz can trigger protective speed reductions before any port bandwidth limit is reached.
