Introducing the Unigraf DPR-120 DP 1.2 Test Device (Full featured DisplayPort™ 1.2 compliant Reference Sink)
Full DP Reference Sink Functionality
DPR-120 is a full featured DisplayPort™ 1.2 compliant Reference Sink. It provides all features needed for testing DisplayPort™ Multistream (MST) source devices like PC display cards or portable computers. The Debug and Test Controller GUI is the user interface of DPR-120. It enables monitoring the performance of the DUT.
Monitor All MST Streams
The DPR-120 allows the user to evaluate the details of both the upstream DP Link and also any MST Stream received. Main Stream Attributes (MSA), Video Status and CRC of color components can be
monitored and logged. The user can additionally monitor, parse and edit both the EDID and the DPCD data of the DPR-120 Sink. All these features are valuable for testing the DUT source with various sink capability scenarios.
Certified Test Tool
Debug and Test Controller GUI is also the user interface for DP 1.2 Link Layer CTS Extensions tests.
VESA has certified Unigraf DPR-120 Reference Sink as the Authorized Test Tool for testing Link layer CTS 1.2 Core and 1.2 Extension Set 1 revision 1.1
