Where 21.5" Fits

Across the Large Size Digital Signage Display range, 21.5" is the smallest of the 12 published sizes in this family — the one to specify when the enclosure, rail or cabinet opening cannot be made any wider.

With a 476.64 × 268.11 mm active area and roughly a 1.8:1 aspect, this behaves like a conventional widescreen panel — the 268.11 mm height sets the cabinet rail, and 1920×1080 renders natively with no scaling. Against the 23.8" next to it in this family, the active area is 50.4 mm narrower and 28.3 mm shorter.
