Our unit was manufactured in March 2021 you can see the label here. Note that some tests, like gray uniformity, may vary between individual units. If you come across a different type of panel or your AOC 24G2 doesn't correspond to our review, let us know, and we'll update the review. Other reviewers have noted some differences in performance however, we didn't test the BOE version, so we can't confirm their findings. The HRR (Hardy Rand and Rittler) Pseudoisochromatic Plates provides the most advanced color vision test.

The figures used by the HRR Pseudoisochromatic Plates are independent of language and suitable for both adults and children.

The Panda version has a serial number that starts with 'ATN', while the BOE version starts with 'AWB'. The Farnsworth Lantern the Dvorine Pseudoischchromatic plates, and the American Optical HRR 2nd edition color plates are the most suitable tests for any airman with a mild color deficiency. Purchase the HRR Color Test 4th Edition from Gulden. The HRR employs a sophisticated test strategy that virtually eliminates the potential for memorization and malingering. The easiest way to tell the versions apart is by looking at the serial number. Due to panel shortage, AOC had switched from using a Panda panel to a BOE panel briefly in 2020, but they seem to have resumed using the Panda panel, which is what our unit has.

There's a 24G2U variant available in some regions that should perform similarly, but it includes a USB hub and built-in speakers. We tested the 23.8' AOC 24G2 monitor, and it's the only size available.
