Features

Learn more

Highest performance USB graphics solution available. Combines both video and audio over a single USB cable and HDMI cable
Connect multiple monitors with resolutions as high as 3840×2160 (4K) to Windows-based laptops or desktops (one adapter required per monitor)
Connects to Windows PCs via SuperSpeed USB 3.0. USB bus powered (no power adapter required). Adapter is backwards compatible with USB 2.0, but in most cases performance above 1080P over USB 2.0 will be unsatisfactory
Supports HDMI displays up to 3840×2160@30Hz. 3440×1440 displays will refresh at 50Hz. 2560×1600, 2560×1440, 1920×1080 (1080P) and all lower modes will refresh at 60Hz * Note: A “High-Speed” HDMI 1.4 compliant cable is required for proper operation at modes above 1080P *
Supports Windows 10/8.1/8/7. Surface RT, Mac OS X, and Linux/Unix are not supported

Performance

4K displays have four times the number of pixels as a 1080P display. With this many pixels, best performance will be achieved when connecting the UGA-4KHDMI adapter to a USB 3.0 port on a PC, allowing SuperSpeed data-transfer rates of up to 5 gigabits per second between the computer and the adapter. The UGA-4KHDMI can be connected to a computer’s USB 2.0 port, though this is not recommended on displays above 1080P as performance will likely be sub-optimal.

The UGA-4KHDMI is completely bus powered, meaning that this device is a simple plug and play device, no additional power supply needed.

Compatibility

Intel Core i5 or AMD Llano 2GHz or better CPU recommended for productivity/web software at 4K. Single Intel HD 4000, AMD HD 7xxx, Nvidia 5xxM or better recommended for productivity/web software. Intel Core i7/AMD A10 2GHz+ and Intel HD 4000, AMD 8650, Nvidia 7xxM or better suggested for full-screen video playback.

Full motion video playback, especially at modes at or above 1080P requires video playback software that supports GPU-acceleration, as well as a compatible primary graphics card and drivers. Does not support HDCP, and will not allow for playback of encrypted Bluray disks. Cannot be mixed with non-DisplayLink USB graphics adapters and drivers (e.g. MCT, j5, or SMSC).

Note: 4K/UHD output requires compatible 4K/UHD display.

DisplayLink DL-5500 Chipset
The USB 3.0 4K HDMI graphics adapter is powered by the same DisplayLink DL-5500 chipset as our UGA-4KDP DisplayPort adapter, and the performance specifications are identical, with support for displays up to 3840×2160@30Hz, 3440×1440@50Hz, and 2560×1600, 2560×1440, 1080P and below at 60Hz. The DL-5500 chipset was designed to have a DisplayPort output, so to provide an HDMI port our new UGA-4KHDMI has an integrated active DisplayPort to HDMI conversion chip.

Drivers for Windows 8.1/8/7 can be downloaded and installed here or via Windows Update if an internet connection is present when the adapter is first connected (a driver CD is also included, but we recommend downloading the updated drivers if possible).

What’s in the Box

The Plugable UGA-4KHDMI comes with a robust, built-in 12″ (30cm) USB 3.0 cable, quick-install guide, and a driver CD.

FAQ

The adapter works great for a few minutes or hours, but then freezes or goes blank suddenly. Unplugging and letting stand for a few minutes before replugging solve the issue for a while.
This may be a unit-specific hardware issue. Please contact us at support@plugable.com and we’d be happy to diagnose and help.

Do Plugable USB docking stations and graphics adapters support Windows 10?
Windows 10 drivers are available for all of our USB docking stations and graphics adapters. As with any new operating system, Plugable recommends that users wait before upgrading any mission critical systems. For additional information on Plugable USB graphics devices and Windows 10, please check out our blog post covering things more in depth.

After a recent update, when I use Chrome on my Mac with a USB graphics device, the window looks distorted. Is there a workaround?
While we don't support our USB graphics devices on Mac, we have reproduced this behavior during internal testing. It appears there has been a regression in the current version of Chrome for OS X (Version 46) which causes graphical distortion when Chrome windows are in use on USB-attached monitors.

Until this issue is fixed in a future version of Chrome, the best current workaround is to disable hardware acceleration in the Chrome settings. To do so: Click the Chrome menu header -> Preferences -> Settings -> Show advanced settings -> Scroll down to "System" -> Uncheck "Use hardware acceleration when available".

To help make Google aware of the issue so they can properly prioritize fixing it, affected users can report the regression to Google using the built-in bug reporter: Preferences -> About -> Report an issue

Windows isn’t giving me the option to select a resolution over 1920×1080 even though I have a 4K display connected. Why can’t I set the resolution higher?
When a display is connected to a graphics adapter, the display passes along configuration information (known as “EDID”) to the graphics drivers and operating system, containing a list of available resolutions. Some models of 4K displays will only accept 4K input on a specific port, while other ports will be limited to lower resolutions. Please check the specifications for the attached display to confirm that a 4K/UHD capable input port is being used.

When using the UGA-4KHDMI graphics adapter with a 4K display, performance on my attached display seems to have more lag than I’m used to. Why?
There are a couple of contributing factors. 4K displays have four times as many pixels as 1080P displays, and updating all of these pixels requires a massive amount of bandwidth. Many of the currently available 4K displays (as well as our UGA-4KHDMI adapter) have a maximum refresh rate of 30Hz when operating at 3840×2160 resolution. As most of us are used to our monitors refreshing at 60Hz, using a display that is refreshing at 30Hz can be a bit of an adjustment.

Additionally, all displays have some amount of “input lag”, which is a measurement of the time it takes for an signal to be received by the TV/monitor, processed, and then displayed on the screen. In many cases, the input lag on an HDTV is substantially higher than that of a PC monitor, and this can contribute to the perception of sluggishness when using a TV as PC display.

The specifications say this adapter has a built-in active DisplayPort to HDMI adapter chip. What does this mean?
The DisplayLink DL-5500 chipset in the adapter has a native DisplayPort output. An active DisplayPort to HDMI conversion chip was added internally to offer HDMI output without the need for an external active adapter. For additional details regarding the underlying functionality of actively adapting DisplayPort to HDMI, please reference the FAQ section of our standalone DisplayPort to HDMI active adapters.

Can the HDMI output be converted for use with a DisplayPort display?
Conversion from HDMI to DisplayPort is not supported. If you wish to connect a DisplayPort display, our UGA-4KDP DisplayPort adapter would be a good choice.

My monitor does support 3840×2160 at 60Hz. Will that allow the UGA-4KHDMI adapter to refresh at 60Hz?
The UGA-4KHDMI will still refresh at 30Hz when running in 3840×2160 mode even if the attached display is capable of 60Hz.

Will 3440×1440/2560×1600/2560×1440 resolutions also refresh at 30Hz?
3440×1440 displays will refresh at 50Hz. 2560×1600 and lower modes will refresh at 60Hz.

Why does the “Display Color Calibration” tool in Windows seems to have no effect on the display(s) attached to my adapter?
The DisplayLink GPU does not support color calibration functionality. Most monitors have built-in controls that can be used to adjust the characteristics of the display, though we realize this approach may not be ideal in all cases. For environments that necessitate near-perfect color reproduction and display calibration capabilities via software, a dedicated graphics card is recommended.
