Plugable UD-ULTC4K

Match each pair to one monitor

You can mix monitor connector types without buying adapters solely to make every screen identical. The current version supports three 4K displays at 60Hz when its native channel receives a suitable DP 1.4 Alt Mode signal. A DP 1.2 host reduces that native channel to 4K30; the two DisplayLink channels follow a different path.

Check which generation is in the listing

Plugable documents an original version and an updated version introduced in 2022. The current catalog entry has three HDMI/DisplayPort pairs and up to 100W host charging, with 96W certification. Do not carry specifications from the newer version into a used listing that shows the older connector layout.

Choose this for workspace, not just pixel counts

A three-screen research or administration desk can benefit from the connection choice and card reader. A buyer whose key task is color-critical work or protected streaming should investigate a native-video alternative. DisplayLink requires software and has workload limitations; a large maximum resolution does not remove them. The display architecture matters more than the number printed on the box.
