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).
