Due to vertical gamma shift (uneven color from top to bottom) TN panels should not be used for comparing these photos, nor should displays with extremely low brightness outputting less than 80cdm/2 brightness.
All monitors were calibrated as well as possible using their menu settings with an X-Rite i1 Display Pro colorimeter and Spectracal C6 HDR2000 (October 2017 and beyond), matched to 140cdm/2 brightness and connected to a PS4 or PS4 Pro (late August 2017 and beyond). The same camera settings and same 15$ CFL Philips 2600 Lumen 6500k/Daylight ceiling light were used for all photos. I continuously update this gallery with a photo of the same image on every monitor I test.
The matte Viewsonic VP2780-4K is the most accurate of them all, but is not my favorite since I prefer the increased clarity and vibrancy offered by glossy coatings.
I'm making multiple other galleries of the monitors I have tested in the last 2 years, including off angle glow comparisons and long exposure photos of dark scenes (The Order 1886; example) with the lights off.

There are multiple kinds of both glossy and matte coatings, some of which are clearer or grainier, or more reflective than others.
