Resolution and Connectivity Comparison
Max Resolution
The Plugable Dual HDMI Universal Docking Station (UD-3900) offers a higher maximum resolution for a single display, reaching 2560x1440 at 50Hz. When using two monitors, it caps at 1920x1200 for both. The Plugable Dual Display USB 3.0 Universal Dock (UD-3900H) supports dual displays up to 1920x1200 at 60Hz. It does not list support for higher resolutions like 1440p or 4K. If you need sharper text for a single large screen, the UD-3900 provides better clarity. The UD-3900H is limited to standard HD+ resolutions across both outputs.
Refresh Rate
Refresh rate affects how smooth motion appears on your screens. The UD-3900H supports a 60Hz refresh rate for both dual HDMI displays. This is standard for office work and web browsing. The UD-3900 also supports 60Hz at 1920x1200 for dual monitors. However, when pushing the resolution higher to 2560x1440 on a single display, the refresh rate drops to 50Hz. For most users, 60Hz is sufficient. The UD-3900H maintains this rate more consistently across both screens without requiring a resolution downgrade.
Video Connectivity
Both docks use HDMI for primary video output. The UD-3900 provides two HDMI ports. The UD-3900H includes two HDMI ports but also lists DVI and VGA compatibility. The second output on the UD-3900H can support HDMI, DVI, or VGA displays using included adapters. This makes it more flexible if you have older monitors or projectors that lack HDMI inputs. The UD-3900 is strictly HDMI. If you need to connect legacy equipment or use specific adapter types, the UD-3900H offers more versatile connectivity options for your display setup.
Physical Build
Size and weight matter for portability and desk space. The UD-3900 is larger, measuring 6.45 inches in length, 4.02 inches in height, and 3.22 inches in width. It weighs 13 ounces. The UD-3900H is more compact, measuring 3.25 inches in length, 1 inch in height, and 9.5 inches in width. It weighs 11.4 ounces. The UD-3900H is lighter and has a lower profile, which may fit better in tight spaces. The UD-3900 is bulkier but may offer a more stable base due to its height. Choose based on your available desk footprint.
OS Compatibility
Both docks support Windows, macOS, and ChromeOS. The UD-3900 supports Windows 10/11, ChromeOS 100+, and macOS 14 or later. It does not support Linux. The UD-3900H supports a broader range of Windows versions, from Windows 7 through 11. It also supports macOS 10.14 and later, along with ChromeOS. The UD-3900H explicitly mentions compatibility with newer Apple Silicon systems, including M4 and M5 chips. If you use older Windows PCs or need broader macOS version support, the UD-3900H is the better choice.
