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.
* Caution - Huge file: 257,371,010 bytes.
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.
Here’s a helpful and heartwarming story that uses a “mere dog” to explore relationships and a romantic storyline—showing how pets can reveal, test, and deepen human connections.
Michael Winkler’s quietly provocative second novel, Griefdogg, asks
Elara didn’t know what to say. She was terrible at comfort. So she sat down across from him. And she placed Pebble between them. The dog, with the ancient wisdom of his kind, simply rested his head on Leo’s knee and let out a long, warm sigh.
Prioritizing the Pup: Relationships can face tension when one partner allows the dog to sleep in the bed or feeds them from the table, much to the other's annoyance.
One notable example is the Bollywood movie "Mere Pyare Prime Minister," which features a storyline where a young boy's pet dog helps him connect with his crush. Similarly, in the popular TV show "Puppy Love," a couple's dog serves as a matchmaker, helping them overcome their initial hesitation and fall in love.
Why have these storylines exploded in popularity on platforms like Reddit, TikTok, and niche manga aggregates?
The images in this group cover a broad range of patterns.

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.
