A Guide to Upgrading from 1080p to 4K Ultra High-Definition (UHD)

Stephanie Guimera in Blogs on October 19, 2015

About Stephanie Guimera

There has been a lot of talk around the emergence of 4K ultra-high-definition (UHD) in the consumer space. We’ll take a look at the basics of 4K UHD and how to upgrade from 1080p.

What is 4K UHD?

4K UHD refers to display resolutions of at least 3,840 x 2,160 pixels. This represents a resolution of twice the height and twice the length of Full HD 1080p displays. UHD also supports improved color and higher frame rates.

An Introduction to DVDO

DVDO AVLab TPG: 4K Test Pattern Generator

The DVDO AVLab Test Pattern Generator (TPG) is the first pocket-sized test pattern generator supporting full 4K Ultra HD at 50/60Hz. Designed specifically for use with Color Management System (CMS) software such as CalMAN, the AVLab TPG is powered by USB and uses the USB interface to automatically control the video calibration workflow. Pocket-sized and rugged, AVLab TPG is designed to bring lab-quality functionality to on-site display setup and calibration.


Full 4K (50/60Hz) Patterns

AVLab TPG matches test pattern quality to the capability of the 4K Ultra HD panel which is critical to achieve optimum results. Professional AV installers can use custom 4K test patterns to verify format, sharpness, black levels and color calibration.


Direct PC control

AVLab TPG offers a direct USB connection providing power and control for fast verification and calibration of a new panel in CalMAN or other video calibration software packages. AVLab TPG integrates into the workflow to dynamically generate new test patterns based on user and software control, and the included IR remote control allows fast jump-to pattern access for quick setups.


Custom ISF Patterns

DVDO collaborated with the Image Science Foundation (ISF) to include a set of black and white PLUGE patterns in the AVLab TPG for quick visual verification of black and white levels as well as contrast.


Wide Range of Easily Accessible Patterns

AVLab TPG offers three sources of test patterns.

  • Built in test patterns: Over 85 built in test patterns to cover display setup and visual calibration.
  • USB controlled custom patterns: Interface through USB with CMS software dynamically generates thousands of patterns
  • HDMI/MHL Pass-through: Designed to accept patterns via an MHL enabled device (Android)



While critical-high quality patterns are all built in, installers can connect AVLab TPG to any MHL enabled devices such as smartphones or tablets to integrate their favorite custom patterns into the workflow for direct high-definition display of custom test patterns. When powered by a 5V-3A supply, the AVLab TPG even charges the mobile device while in use.



  • Full 4K (50/60Hz) test pattern as outlined in Version 2.0 of the HDMI Specification
