Can it really run four monitors at once?

The dock has four video outputs, but the laptop's GPU and OS cap how many displays work and at what resolution. Check your laptop's multi-display support before buying.

Does it work with both Windows and Mac laptops?

It is sold as a universal dock, so it is meant for Windows and macOS machines with the right USB connection. Some Macs limit external display count, so confirm yours first.

Does it charge the laptop?

Power delivery varies by model and laptop, so check the dock's power output against your laptop's charger wattage. Very power-hungry laptops may need their own charger.

What ports does it add?

Expect the four display outputs plus USB-A and USB-C ports, wired Ethernet and audio. Exact port counts differ by version, so check the listing for yours.

Is it better than a dual-display dock?

Only if you actually use three or four screens. For two monitors a smaller dual-display dock takes less desk space and usually adds less latency.

What comes in the box?

Typically the dock, a power supply and a USB cable to the laptop. Video cables are usually not included, so plan for the right HDMI or DisplayPort cables.
