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.
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.

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.
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.
Released in 1993, Wayne's World 2 is a comedy film directed by John Landis, starring Mike Myers and Dana Carvey as the iconic duo, Wayne and Garth. The movie is a sequel to the 1992 hit film Wayne's World, which was based on the popular Saturday Night Live sketch of the same name.

Despite being one of the most famously troubled productions of its era, Wayne's World 2 has aged into a cult classic — a gloriously absurd, meta sequel that many fans now argue is just as good (if not better) than the original.
The station manager tells them the show is being canceled for low ratings. A sleazy streaming exec named Chad Thundercock (a parody of every tech bro) offers them a deal: “We’ll give you a show, but you have to add algorithm-friendly segments like ‘Hot Wings or Hot Takes?’ and a reaction cam to your reaction cam.”
Wayne's World 2 (1993) is the surreal, rock-infused sequel to the cult classic original, continuing the adventures of Aurora, Illinois' favourite public-access hosts. While it didn't match the first film's box office heights, it is celebrated for its dense pop-culture parodies and "Waynestock" concert plotline. Released in 1993, Wayne's World 2 is a

with intentionally bad English dubbing and a The Graduate parody that is surprisingly well-executed [5.12, 5.29]. Ralph Brown’s roadie character, Del Preston
Interestingly, Dana Carvey later mentioned on the Fly on the Wall podcast that the sequel felt like the "sellout version" because they had a much larger budget [5.20]. While the sets look more "fantastical" and less like a basement in Aurora, that absurdity is exactly what makes it a cult favorite today [5.7, 5.20]. Final Verdict: Sch-yea!
Party On! An Informative Look at Wayne’s World 2 Released on December 10, 1993, Wayne's World 2 brought back the lovable metalhead duo, Wayne Campbell (Mike Myers) and Garth Algar (Dana Carvey), for a sequel that balanced surreal humor with a grand musical mission. While it faced the challenge of living up to the massive cultural impact of the original, it carved out its own legacy through legendary cameos and parodies. The Quest for Waynestock Heather Locklear : Plays a fantasy version of herself
—a move Spheeris later called a mistake. This rush helps explain why the film has the feel of a spontaneous jam session rather than a tightly constructed corporate product.
While the 1990s aesthetic—baggy flannels, heavy guitar riffs, and massive hair—dates the movie to a specific era, the humor remains timeless. The core themes of Wayne's World 2 are universal: following your dreams, sticking by your friends, and refusing to sell out to the corporate machine.
Cassandra’s slick new producer, Bobby Cahn (Christopher Walken), attempts to steal her away and move her to Los Angeles, forcing Wayne to fly across the country to save his relationship. The Anatomy of the Comedy
The film features one of the greatest musical cameos in comedy history: Aerosmith. The band's appearance is the climax of the film, providing a legitimate rock-and-roll payoff to the buildup of Waynestock. It was a major coup for the production, as the band had famously turned down appearing in the first film.

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.
29 Dec 2023 - Replaced WUXGA-1900x1200 with WUXGA-1920x1200. Original was in error. Thanks, Shawn, for pointing this out.
