Quality.TV Full HD and Ultra HD universal test

Quality.TV - for precise and efficient picture tuning!

The Quality.TV Universal test from Florian Friedrich and Joe Kane was designed based on the needs of some of the leading review magazines for televisions and projectors.

Many international experts helped us to compress the most important tools for evaluating and optimizing a elementary set of test patterns into a 5-minute-video, available for download here.

The Quality.TV universal Full HD and Ultra HD test is designed to be a important tool for your initial setup of new devices, helping you to convey the artistic messaage of the filmmakers.

The picture quality tuning of the professionals. No measurement devices needed!
This universal test enables perfect adjustments of the TV picture controls
in a few simple steps!
This (and more) can be done with the test patterns:
  • Adjustment of brightness and contrast - using the Universal pattern as well as the black level- and white level- testpatterns
  • Adjustment of the color saturation - using the combined pattern as well as the innovative "R,G,B only" test pattern with color saturation and color luminance steps
  • Optimization of the sharpness - using the combined pattern as well as the Overscan- or Pixel Phase-testpattern
  • Identification and elimination of unwanted side effects from so called "picture improvement circuits" - using the Universal pattern as well as the RGBW-Zoneplate
  • Selection between Cineastic Motion Judder or video look with frame interpolation - using the Moving Text pattern
  • Review of the most important quality factors of a TV - including scaling, color decoding and framerate conversion
  • Identification of the dynamic range using HDMI-sources (full range or limited range)
  • Test of different players, adjustments and connection types
  • In-depth-overview over the picture quality aspects as soon as after 5 minutes (length of the testpattern-video)

Included test patterns in detail:

The universal test videos in Full HD and Ultra HD consist of 10 specialized patterns, all with a duration of 30 seconds and put together in a 5-minute-video. If you are burning the BD-image (ISO file) to a Blu-ray, you'll also be able to skip to the individual patterns by using the chapter function of your player.

Test pattern / sequence

Description

Applications

Combined (Universal) Pattern for a fast overview of the most important system parameters and picture adjustments. With resolution patterns, PLUGE, control fields for color saturation, overscan scales, convergence crosses, skintone reference and more.

  • Adjustment of brightness
  • Adjustment of contrast
  • Adjustment of sharpness
  • Adjustment of color saturation
  • Adjustment of aspect ratio and overscan
  • Adjustment of brightness
  • and more

Overscan-Testpattern with markers for percentage values, save action, save title, letterbox markers and more

  • Selection of the ideal aspect ratio in order to avoid scaling artifacts and overscan
  • Adjusting the aspect ratio and zoom
  • Review of the overscan in percent
  • Finding blackdrop positions for projection systems

Blacklevel-Testpattern 

The top, bottom and vertical center of the image is at video black, level 16.  There are single level steps out towards the left and right edges.  Markers have been placed at the –4%, +2% and +4% video steps used in the PLUGE pattern.

  • Adjustment and control of video brightness
  • Identification of system limitations and clipping

Whitelevel-Testpattern

The top and bottom of the image is at level 235 (video white).  Levels from the center out towards the left and right edges start at single level steps and then jumps to 2 levels per step.  Markers are placed at 95%, 100%, 105% and 109%.

  • Adjustment and control of image brightness
  • Identification of system limitations and clipping

Combined Blacklevel and Whitelevel-Testpattern

Black levels and white levels from the pictures before combined into a single pattern.

  • Adjustment and control of video brightness
  • Adjustment and control of video contrast
  • Identification of system limitations and clipping

Color Luminance & Saturation Steps

Each step represents a 5% change in level (top) or saturation (bottom). In the top three sections of the pattern the steps are reversed left to right, at the top running from 235 to 16, and stepping up from 16 to 235 at the bottom of each section.

  • Adjustment of the color saturation
  • Adjustment of the color tint
  • Review of the color decoding
  • Identification of the side effects of picture improvement circuits
  • Advanced tests with R,G,B only mode of TVs and projectors

Pixelphase-Testpattern with phaseshifted pixel rasters to the limits of Full HD / Ultra HD resolution.

  • Adjustment of the sharpness
  • Check for side effects of sharpness- and edge enhancements
  • Review of the resolution of TVs and projectors (especially 3-Chip LCD, D-ILA and SXRD)
  • IIdentification of frequency-dependent colorizations

Ultra HD / Full HD Distance Finder & Phase Modulation
Resolution bursts, concentric circles and resolution wedges with sinusodial waveforms. Highest frequency as rectangular waveform. A continuos phase shift (360 degree/10 seconds) is adding motion to the pattern. Markers for minimum and optimum viewing distance.

  • Finding the maximum viewing distance for visible differences with UHD TVs *
  • Finding the ideal individual viewing distance in order to recognize the highest UHD-Resolution *

*UHD patterns must be used for UHD resolution sets. Full HD patterns are restricted to 1080p use.

RGBW-Zoneplate with Phase Modulation

This particular zone plate starts at a relatively
low frequency at the center of the image and then get higher and higher going towards the outside of the image.  The amplitude is essentially between video black and video white.  There is a constant phase shift in the circles that makes them appear to be moving.

  • Identification of interferences caused by edge enhancements or sharpness filters
  • Tests for chroma subsampling and chroma upsampling

Moving Text at Different Speeds

Font sizes for each bar are 80, 40 and 20.  There are color and luminance shifts in the fonts. Motion at the top is the slowest, taking 30 seconds for the image to move across the screen.  The bottom takes the least amount of time to cross the screen, doing so in 3 seconds.  All of this is being done at a refresh rate in the source material of 23.976 frames per second.

  • Motion artifact identification
  • Rating of the frame interpolation and framerate conversion
  • Rating of motion blur

Application note: Ideal adjustment of brightness

This following document will explain how to adjust brightness correctly on your TV or projector and it also includes some technical backgrounds on video levels.
