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.

HDMI Transmitter and eARC Compliance Solution 

With each successive generation, HDMI source developers face faster data rates and new test challenges. HDMI 2.2 doubles the available bandwidth to up to 96 Gbps while continuing to leverage multi-lane Fixed Rate Link signaling, significantly expanding test coverage and increasing validation complexity. Higher resolutions, refresh rates, and uncompressed formats—including advanced 4K, 8K, and beyond—demand precise validation across a broader set of electrical and protocol conditions. Differential, eye diagram, and single-ended measurements now require even higher signal integrity, lower noise floors, and greater measurement accuracy to ensure reliable characterization of next-generation devices.

With no connection changes or manual intervention required between tests, the Tektronix test solution delivers streamlined setup, ease of use, and high measurement fidelity—reducing overall test time while ensuring comprehensive compliance and debug coverage for all HDMI 2.2 Tx and eARC (Tx & Rx) measurements.

DisplayPort Transmitter

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.
