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.

If you’ve landed here, you’ve probably typed into a search engine. At first glance, the keyword appears chaotic—a mix of a popular web series title, a non-standard episode number (0112), and a mysterious term “Webri Work.” However, for the dedicated fanbase of ALTBalaji and ZEE5’s hit horror-erotic thriller, this search query represents a specific, niche demand.
By 2017, the shift toward Over-The-Top (OTT) digital platforms allowed creators to bypass strict traditional theatrical censor boards. Recognizing this shift, Balaji Telefilms adapted the formula into a long-form streaming serial, culminating in Ragini MMS Returns Season 1 .

This review was drafted for Webri Work standards. Copy may be edited for length depending on platform (IMDb, Letterboxd, or blog).
The first two episodes of Ragini MMS Returns Season 1 succeed because they understand the grammar of digital horror. Found footage, when placed in a web series, feels immediate and invasive. The show uses its format to explore voyeurism, consent, and the supernatural, all while delivering effective scares. For students of horror or digital media, these episodes are a textbook example of how “webri work” can transform familiar tropes into something urgent and unsettling.
Drama / Lifestyle / Corporate (Work-Life Balance) Format: WebRI (Web Release)
The "Webri" (WebRip) tag indicates this was ripped directly from a streaming source (likely ALTBalaji or ZEE5). Consequently, the visual and audio fidelity is entirely dependent on the platform's compression. The show is presented in a 16:9 aspect ratio, usually in 720p or 1080p, but suffers from the "soap opera effect"—flat lighting and digital noise in darker scenes, which is detrimental for a horror series relying on atmosphere.

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.
