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.

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.
