Yes, you can run two monitors from one USB-C port, but your port must support DisplayPort Alt Mode (DP 1.2+ with MST) or Thunderbolt 3/4, and your monitors or dock must also be compatible.
- Your USB-C port supports DisplayPort Alt Mode with MST or Thunderbolt 3/4
- You daisy chain via monitors with DP 1.2+ MST and a DP Out port
- You use a Thunderbolt or USB-C dock with DisplayLink
- GPU drivers are up to date and you are on Windows
- Your USB-C port is data-only with no DisplayPort Alt Mode
- Your monitors lack MST support or a DP Out port
- You try to daisy chain using HDMI connections
- You use a basic USB-C hub without DisplayLink or DP MST
Three Ways to Drive Two Monitors From One USB-C Port
There are three practical methods. Each has different hardware requirements and trade-offs.
- Daisy chaining: Connect USB-C to the first monitor’s DisplayPort input, then run a DP cable from that monitor’s DP Out to the second monitor. Both monitors must support DP 1.2+ MST.
- Thunderbolt or USB-C dock: A quality dock with two or more video outputs handles the splitting internally. Thunderbolt 3/4 docks typically support two 4K displays simultaneously.
- DisplayLink adapter or dock: DisplayLink uses USB bandwidth and software compression to output video over standard USB-C, even without DP Alt Mode. Good for office use, but may show slight lag in video or animation.
Before choosing a method, check whether your USB-C port actually supports video output — many USB-C ports on budget laptops are data-only.
Compatibility at a Glance
| Setup | Works? | Need | Note |
|---|---|---|---|
| Daisy chain via DP MST | Yes | DP 1.2+ MST on port and both monitors | Best image quality |
| Thunderbolt dock | Yes | Thunderbolt 3/4 port | Supports dual 4K |
| DisplayLink dock | Yes | USB-C port (any); DisplayLink drivers | Minor lag possible |
| Basic USB-C hub | No | — | Single video output only |
| HDMI daisy chain | No | — | HDMI does not support MST |
macOS vs Windows
Windows has the broadest support for MST daisy chaining and DisplayLink. macOS supports dual monitors through Thunderbolt docks but has limited or no support for DP MST daisy chaining on non-Apple Silicon Macs. Apple Silicon Macs (M1 base model) restrict external display count in hardware, so always check your specific Mac model before buying a dock.
If you are connecting to a different display type, check out our guide on whether USB-C can connect to HDMI for what to expect with mixed monitor setups.
Dell’s official guide to daisy chaining monitors is a useful reference for checking whether your specific Dell display supports MST out.
Quick Checklist Before You Buy
- Confirm your laptop’s USB-C port supports DP Alt Mode or Thunderbolt — check the spec sheet or look for the Thunderbolt lightning bolt icon
- Verify each monitor has a DP 1.2 MST input and DP Out if daisy chaining
- For DisplayLink, download drivers before plugging in — plug-and-play will not work without them
- Update your GPU drivers on Windows before testing
Bottom line: You can run two monitors from one USB-C port, but the key is matching the right method to your hardware. Thunderbolt docks are the most reliable option; daisy chaining works well when both monitors support MST; and DisplayLink is the fallback for any USB-C port when image quality requirements are modest.
