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.

It sounds like you're looking for a compelling story about the hidden costs and consequences of using cracked software. While the promise of "free" pro tools like Adobe Lightroom CC is tempting, the reality often turns into a digital nightmare. Here is a story of a photographer who learned the hard way. The Perfect Shot, the Digital Rot Kaito was a rising star in urban photography. He had the eye, the gear, and a growing following, but he was broke. When his Lightroom trial ended, he couldn't bring himself to pay the monthly subscription. A few clicks on a shady forum later, he had it: a "pre-cracked" version of Lightroom CC. At first, it felt like a victory. The interface looked the same, the sliders worked, and Kaito was pumping out his signature neon-drenched cityscapes. He thought he’d beaten the system. But the cracks started showing—literally. The First Glitch: Two weeks in, the software began to lag. A simple brush adjustment took five seconds to register. The Disappearing Act: One morning, Kaito opened his catalog to find three months of work—thousands of meticulously edited RAW files—gone. The cracked installer had included a "time bomb" script that corrupted his catalog database. The Breach: It wasn't just photos. His laptop started running hot even when closed. A hidden crypto-miner was burning through his CPU, and soon, he received alerts for unauthorized login attempts on his bank account. The "free" crack was actually a backdoor for malware. Kaito lost his portfolio, his privacy, and his trust in his own tools. He realized that professional work requires professional integrity. He wiped his drive, started over from scratch, and signed up for the Here is a story of a photographer who learned the hard way

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.
