DisplayPort Interface

Future of Display Technology

Display standards such as DisplayPort™ and HDMI continue to revolutionize display interfaces in a variety of applications, including laptops, monitors, and docking stations.

Defined by the Video Electronics Standards Association (VESA), DisplayPort version 2.0 significantly increases data rates. This enables a higher dynamic range, improves refresh rates, and supports the highest display resolutions.

Our comprehensive solutions are adaptable to fit your unique display testing needs for VESA or HDMI certification. Our automated software dramatically reduces test time and complexity by handling setup and calibration.

DisplayPort 1.4a Transmitter Compliance Solution

Engineers designing DisplayPort silicon for computer and embedded systems or validating the physical layer compliance of DisplayPort devices need comprehensive solutions.

With Tektronix oscilloscopes and software analysis tools such as DPOJET and SDLA, designers can characterize DisplayPort 1.4 source devices operating at HBR3 (8.1 Gbps). Our DP1.4 solution performs all transmitter testing including compliance in under 7 hours at HBR2 (5.4 Gbps) and 11 hours at HBR3.

  • Supports Standard DP, mini-DP and USB Type-C connectors
  • Fully automated DUT controlling with intelligent pattern recognition
  • Optimized measurement algorithms execute tests faster with improved accuracy

HDMI Transmitter and eARC Compliance Solution 

With each successive generation, HDMI source developers face faster data rates and new test challenges. HDMI 2.1 increases data rates up to 48 Gbps over 4 lanes, expanding test cases and test times. Differential, eye diagram and single-ended measurements require high signal integrity with the lowest noise to accurately measure device performance.  Enhanced Audio Return Channel (eARC) is a new feature which simplifies audio connectivity and supports the most advanced audio formats and highest audio quality.

With no connection changes or manual interventions required between tests, the Tektronix test solution provides simple set-up, ease of use, measurement accuracy and reduced test times for all HDMI Tx and eARC (Tx & Rx) measurements.

Embedded DisplayPort (eDP)

Embedded DisplayPort (eDP) is a standard designed specifically for mobile and embedded displays. In contrast to other display protocols, eDP has reduced transmitter voltage swings and lower receiver sensitivity requirements, making it a great option for power-sensitive mobile applications. These and other low-power features supported by eDP introduce new test and debug challenges for both source and sink devices. The Tektronix eDP solution provides engineers with an easy and fast way to debug eDP Tx devices.
