Dual 4K USB-C Adapter

The Anker A83240A1 turns a single USB-C port with DisplayPort Alt Mode into two HDMI outputs. It is built for professionals who need dual extended displays from a laptop, tablet or phone without installing drivers.

Thermals and Power

The compact adapter draws power from the host port and runs without a fan, so it adds no audible noise to a quiet workspace. Its low-profile design keeps heat dissipation simple during typical office or home use.

Build Integration

The half-inch thick housing fits between monitors on a crowded desk and works with Thunderbolt 3 ports. macOS and iPadOS limit output to Single-Stream Transport, while Windows enables Multi-Stream Transport for independent dual 4K@30Hz or dual 4K@60Hz when the host supports DP 1.4.

Questions about this item

How do I install the Anker A83240A1 and what step do people often miss?

Plug the USB-C end into a port that supports DisplayPort Alt Mode, then connect both HDMI cables. The step often missed is confirming the host device supports DP 1.4 for dual 4K@60Hz or DP 1.2 for dual 4K@30Hz.

What maintenance or replacement will the Anker A83240A1 need later?

The adapter has no moving parts or consumable components, so no scheduled maintenance is required. Replacement would only be necessary if the unit is physically damaged or the USB-C connector wears out after extensive insertion cycles.

What limit appears first during sustained use of the Anker A83240A1?

The primary limit is the host device's DisplayPort version. Laptops with DP 1.2 are capped at dual 4K@30Hz, while DP 1.4 devices can reach dual 4K@60Hz. macOS and iPadOS further restrict output to single-stream transport mode.
