Dell WD15 vs WD19
The WD19 adds newer video connections and higher resolutions with a suitable laptop. For two Full HD screens, the WD15 may already do the job.
Both use USB-C with DisplayPort video support. A USB-C socket alone is not enough, and neither dock needs DisplayLink software.
| What changes | WD15 | WD19 |
|---|---|---|
| Video ports | HDMI, Mini DisplayPort and VGA | Two DisplayPorts, HDMI and rear USB-C video |
| One 4K screen | Up to 30 Hz through HDMI or Mini DisplayPort | Up to 60 Hz with HBR3 laptop video support; 30 Hz with HBR2 |
| Two screens on Windows | Up to 1920 × 1200 each at 60 Hz | Up to 2560 × 1440 each at 60 Hz with HBR3; Full HD with HBR2 |
HBR2 and HBR3 describe the laptop’s DisplayPort link speed. These are dock limits, not a guarantee for every laptop. The WD19’s HDMI and rear USB-C video output cannot drive separate screens simultaneously.
Which should you choose?
- Keep a working WD15 for two Full HD office screens or a VGA monitor. Check that the necessary cables and power supply are included.
- Choose a WD19 for its DisplayPort connections, or higher resolutions when your laptop supports HBR3. A larger power supply alone will not improve screen support.
- Check Macs separately. These Windows multi-screen limits do not establish two independent extended displays on macOS.
Both need a compatible power supply. For the WD19, 130 W and 180 W supplies have different laptop-charging ceilings.
