 The KX-21HV1 is the smaller sibling of the [[Sony KX-27HV1|KX-27HV1]], sharing the same Profeel Pro design language and feature set in a more compact 21-inch form factor. Like its larger counterpart, it was nicknamed "Yagura TV" (やぐらテレビ, "tower TV") internally during development due to its distinctive angular frame design that allowed units to be stacked at events and exhibitions.
-The monitor features an extensive array of connectors including an [[EIAJ-8]] Digital RGB input for [[TTL RGB|TTL-level signals]], a [[JP21]] connector for analog RGB (TTC-003 compliant), an [[8-pin DIN 45326]] multi-input, and three additional composite video inputs. For system integration, the monitor includes Control S input and output jacks (3.5mm mini-jack, 5Vp-p) allowing remote control of compatible Sony equipment. The included remote control (RM-543) is shared with the KX-27HV1.
