Pattern resolution is intended to match native resolution of the display. At any other resolutions where the pattern size is scaled to the display size scaling artifacts will render many patterns useless. If your viewing program supports a scaling factor of 1:1, that is, one pixel in the image maps to one pixel in the display, then patterns not matching the display resolution will show without artifacts but intent of some of the patterns will not be attained.

Pattern Files

Here are links to zip files containing test patterns for HDTV and common monitor resolutions. Each zip file contains 206 unique patterns arranged in groups by file name. These files are named with the actual resolution and a descriptive resolution identifier taken from a Wikipedia article.

Pattern Groups

The tables below describe the groups that make up the files in the above zip files. The images are examples of typically a subset of the contents of a group. They are not links to the full size images, which are only available in the zip files. This is because of the amount of room the uncompressed files in all the resolutions would consume.

The thumbnails (160x100) in the examples show artifacts arising from the small size. These do not appear in the full-size images.

Quick Check Patterns

These patterns are intended for a quick, overall assessment or check of a display. The use of the term checkers is unrelated to the term check. Checkers refers to an alternating black/white pattern similar to a checkers board and is frequently used with gamma patterns. Check refers to assessment or evaluation.

"S55" represents the studio season, shooting batch, or internal project code, while "PROD" designates it as a finalized production asset rather than raw B-roll.

Here is an exploration of the themes surrounding such digital content. The Rise of Curated Digital Lifestyles

In the United States, the legal fight against animal crush videos has been ongoing for decades. In 1999, the U.S. Congress passed a law aimed at criminalizing the creation and distribution of crush videos. This law was later struck down by the Supreme Court in 2010 in United States v. Stevens , which ruled that the law was overly broad and violated First Amendment protections of free speech. In response, Congress enacted the (18 U.S. Code § 48). This revised law was crafted more narrowly, restricting its focus to "obscene" depictions of animal crushing that are illegal to sell, market, or distribute.

: Mainstream entertainment brands frequently pull aesthetic cues from older internet subcultures, turning underground video concepts into high-fashion aesthetics and viral marketing campaigns.

The psychological satisfaction for the viewer often lies in the contrast between the fragility of the target and the absolute, irreversible force applied by the crushing agent. The slow, deliberate pressure, the close-up visual of the foot, and the audio elements (squishing, cracking, or the shoe against the floor) combine to create a sensory experience that triggers the desired arousal response. "S55" represents the studio season, shooting batch, or

The inclusion of terms like "crush fetish" highlights how early digital media allowed highly specialized subcultures to find a voice, build communities, and form sustainable micro-economies.

The "crush fetish" (also known as soft crush or hard crush) is a paraphilia where individuals find sexual arousal in seeing items flattened. In 1999, the U

History

Many years ago I posted some HDTV test patterns to Flickr. They were quite popular, received quite a few hits, and were probably linked from another site but I never found where.

In December, 2013, I wrote a new generating program in Python, included several composite images, many geometric and color images and used descriptive file names. These were, and continue to be, some of my most popular images on Flickr but at Flickr they were only in a resolution of 1920x1080.

In March, 2023, I converted the generating program from Python2 to Python3 correct a bug causing vertical lines in one of the color images, changed the name of the image files, updated the resolutions, and added many new patterns including the inverse of several.
