Monitors & TVs
Resolutions up to 10K
As resolutions in monitors and TVs reach up to 10K, a need for proper testing grows stronger. With resolutions up to 8K and beyond it is impossible to detect errors with the bare human eye.
What to Test in Monitors and TVs?
Video & Audio
In receiver devices such as monitors, it is crucial to test that each functionality works seamlessly with different types of transmitter devices such as game consoles or Blu-ray players. With proper test tools, you can test all functions of the transmitter-receiver pairing in a reliable and controlled manner.
With a proper test tool, you can generate video with different resolutions and color formats. Unigraf’s test tools feature a built-in pattern generator that enables generating video up to 8K@60Hz or 10K@30Hz. Custom timings and patterns are also available. Similarly, an audio generator can be used to generate an audio stream. You can either create an audio stream with a built-in audio generator or upload an audio file to be used in testing. Unigraf’s test tools can also play and capture compressed audio.
The screenshot below shows the built-in pattern generator in UCD Console
Link & HDCP
It is crucial to monitor and control the link between the monitor and transmitter device (e.g. game console). With a proper test tool, you can monitor and control the link status.
UCD Console GUI also provides a monitor and control for enhanced gaming feature Variable Refresh Rate (VRR).
A proper test tool enables the controlling and monitoring of HDCP encryption. As HDCP encrypted video stream cannot be saved on your PC for testing, you need to test that the HDCP encryption is working correctly with a proper test tool. Unigraf’s UCD series test tools enable testing HDCP encryption up to HDCP 2.3.
Screenshots below show the tabs for Link and HDCP monitoring and controlling.
Compliance Testing for DisplayPort
Link Layer CTS Testing
The core of the DisplayPort compliance testing is the Link Layer Compliance Testing. The Link Layer compliance testing is always done according to the latest DisplayPort specification. In the link layer compliance testing the link between the transmitter and receiver devices is analyzed and tested according to the specifications. Also, all of the different timings (e.g. 4K@60Hz) that can be transmitted under the specifications are tested.
For DP 2.0 Link Layer CTS Testing: UCD-500
For DP 2.0 Link Layer CTS Testing: UCD-400
HDCP 2.3 CTS Testing
DisplayPort devices employ HDCP encryption to protect the digital content. In 2018 VESA announced that it requires HDCP testing as part of the DP testing requirement for certification. If a DP Source or Sink supports HDCP (as reported in the product CDF) it shall be tested as part of the certification requirements for obtaining the DP Logo. (Source: VESA). The latest HDCP specification is the HDCP 2.3 which is used in smartphones that support USB-C DP Alt Mode

Dolby Vision™
What is Dolby Vision™?
Dolby has worked closely with industry leaders over the last 50 years to make the stories and experiences as engaging as possible—first with noise reduction, then 5.1 surround and 7.1 surround, and now with Dolby Vision™. Dolby Vision™ transforms the way you experience movies, TV shows, and games with incredible brightness, contrast, and color that bring entertainment to life before your eyes. By fully leveraging the maximum potential of new cinema projection technology and new TVs’ display capabilities, Dolby Vision™ delivers high-dynamic-range (HDR) and wide-color-gamut content. The result is a refined, lifelike image that will make you forget you are looking at a screen.
4K televisions have “more pixels” and newer standards for UHD TV also include high frame rates, but these standards don’t make each pixel able to better represent the full range of brightness we see in reality. Dolby Vision™ is the Dolby Laboratories solution to meet this challenge. The current TV and Blu-ray standards limit maximum brightness to 100 nits and minimum brightness to 0.117 nits, while also limiting the range of colours that can be displayed. Dolby Vision™ colour depth allows up to 10,000-nit maximum brightness. (Dolby 2016)
Dolby Vision Testing
In the compatibility test for Dolby Vision™ Unigraf will provide playback and capturing of the test video and audio content with UCD-series test tools. Dolby will provide customers with the SDK (Software Development Kit) that enables analyzing the Dolby Vision™ video captured with UCD-series test tools. UCD-series test tools also support Dolby Vision signaling test using Dolby Vision VSIF and Dolby Vision Vendor Specific Extended Metadata Packets (EMP) using TMDS. With the Dolby SW package, UCD-series test tools are a mandatory tool for any e.g. television or monitor manufacturer that is willing to have a Dolby Vision™ certificate on their products.

HDR10+ Testing
Unigraf’s UCD-323 and UCD-422 are approved for HDR10+ compliance testing. Unigraf’s HDR 10+ Display Device Test License allows HDR 10+ adopters to generate HDR 10+ specific patterns that are required by HDR 10+ LLC to certify Sink devices such as TVs and Monitors for HDR 10+.
Unigraf’s solution integrates Klein K-10A colorimeter for automated testing of HDR 10+ Display Device tests allowing users to set and play the patterns without having to manually measure luminance values of HDR 10+ patterns. Users that do not have Klein K-10A colorimeter will be able to manually record measured luminance values into the software GUI. This solution is easy to use and reduces the time required to run HDR 10 Display Device certification tests.
