This collection of test patterns and instructions can get your display looking its best with a few simple tweaks.

Free returns are available for the shipping address you chose. You can return the item for any reason in new and unused condition: no shipping charges. They are more accurate than the test patterns found on previous discs. There are a lot of subtle details that go into making them as mathematically accurate as possible, especially since you are dealing with lossy encoding. We have built propriety tools to generate the synthetic patterns. We use a custom encoder that will preserve as much detail as possible.

Please select the appropriate options below to determine the correct size bias lighting for your displays. You should round up to this size bias light you can round down at your discretion if the actual and rounded measurements are very close. It is usually better to have more than too little :. These discs represent the culmination of literally decades of research and development to create the absolute highest quality test material for video and audio. Each of these patterns was hand-built using software created by us. Every line and grid is positioned with sub-pixel accuracy, and levels are dithered to produce accuracy to 5 digits of precision. No other test patterns can boast similar accuracy. Our hope is that these discs will be useful to both the newcomer to high-end video and the professional video engineer or calibrator. There is literally something for everyone here. Please visit our website: www. This section of the guide is designed to take you step-by-step through a straightforward set of adjustments and calibrations that any home theater enthusiast can perform without needing any special test equipment. At the end of this process, you will:.

The previous iteration was a single disc with 1, encoded files, which represented a high-water mark for evaluation discs at the time. The set also introduces pop-up help to simplify the calibration process. It also expands the range of formats and encodings. There is also a new Peak Luminance test pattern, designed to achieve a more accurate measurement than the legacy window pattern, and a Pixel Aligning pattern for breaking in new OLEDs. On the audio side, the set includes test material in the object-based Dolby Atmos and DTS:X surround-sound formats with tones covering setups ranging from 5. Needless to say, every display does it a little differently — now, with the Ultra HD Benchmark , enthusiasts and professionals will be able to get insight into exactly what the display does when it makes those important remapping decisions. There are no ISF calibrators near me, so I just placed a pre-order for this new disc.

But it's also the most thorough, including three discs, a multi-page "manual" that guides you through the basic process, and a set of filters for setting a TV's Color and Tint controls. The authors don't actually recommend using the controls however, as no such filters, even these, are totally accurate. I've long avoided these filters. Instead, and as is the recommendation here, I leave these two controls in their as-delivered defaults usually centered. They might have had some value in the CRT TV era, where few easily accessible setup controls were offered to the viewer. But their value in modern digital TVs is dubious at best.

It was extremely useful to have my player display in RGB. Most sections have subsections, which are arranged along the top of the screen. SDR footage. In general, we recommend sticking with displays that have a true native panel with the full UHD resolution. Evaluation Color This subsection contains patterns useful for evaluating common color-related quality and performance issues found in modern video displays. Luminance Sweeps This subsection contains luminance sweeps useful for automated calibration software. The Demonstration Material comes in a variety of formats and peak luminance combinations, which are listed explicitly in that section. Once you have all the rectangles visible or as many as possible , increase the Contrast control until at least one rectangle disappears, then lower it one notch to bring back the rectangle s that just disappeared. I found the articles section had better instructions than the manual. As with the Sharpness control, adjust them until they produce a nice clear picture with minimal distracting artifacts. This is totally a 5 star product. A basic 5 minute demo video of landscape scenes is provided so you can check your settings on actual content that's been well-encoded and properly color balanced. These patterns are all encoded at Secure transaction Your transaction is secure. Disables all tone mapping and makes the display use its own native transfer curve.

Preparation Perform the calibration under the same lighting conditions you generally use to watch quality material like movies. If there are windows in the room that let in sunlight and you tend to watch movies at night, then the calibration should also be performed at night. If your display has multiple picture memories and you watch the display under multiple lighting conditions, it may be worthwhile to perform the calibration separately for each of the lighting conditions and assign each one to a different picture memory.

Our visual system is very sensitive to skin tones, and artifacts are often most visible on smooth skin tone gradations. Saturation Sweeps This subsection contains saturation sweeps useful for automated calibration software. You should run the tests separately for both audio formats if your system is capable of playing both. Their latest product is the version of the Ultra HD Benchmark. Motion This subsection contains patterns useful for evaluating resolution and other performance characteristics in moving video. Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them. March 7, Other formats which are noted have been tone mapped to reduce the peaks to a lower level, with all the other levels adjusted to produce a finished video that is aesthetically as close as possible to the reference while minimizing ugly clipping in luminance or saturation. This setting only applies to the patterns in the Analysis section of the disc, and only when the Video Format is set to Dolby Vision. Then adjust Sharpness up until you start to see artifacts, or until they get highly visible.
