The latest high-definition displays such as High-Definition Televisions (HDTV) and LED displays contain some of the most complex signal processing found in consumer electronics. With support for 240 Hz refresh rates, 48-bit deep color, 3D content, and 4K2K resolution, these devices require extensive processing to deinterlace, upscale, decode, and unpack content being distributed by other multimedia devices.

Growing consumer expectations for these devices combined with a market that continues to drive down consumer cost creates interesting challenges for engineers in validation and production test to lower test costs without sacrificing product quality.

With the resources throughout the Approach and Overview tabs, learn how NI and certified National Instruments Alliance Partner Alfamation created solutions based on PXI and NI LabVIEW that can help you test the latest high-definition displays faster, cheaper, and with higher quality.


With NI modular hardware and configurable software tools, create lower cost and higher throughput solutions for your high-definition display test applications.

Learn how to use National Instruments and Alfamation tools to build a complete functional test system for HDTV mainboards as well as glass displays. In the following tutorials, find key strategies for architecting test solutions for HDTV mainboards as well as analog and digital video fundamentals. These resources can help you get started in designing your test system.

NI also has certified Alliance Partners that can develop a turnkey, multi-UUT test system specific to your application. To learn more, contact your local NI field engineer.
