The Sony KX-27HV1 is a professional 27-inch presentation monitor manufactured and released by Sony in August 1986 as part of the Profeel Pro series. It uses Sony's Black Trinitron system to provide a high-quality display with 560 lines of horizontal resolution.

Overview

The Profeel Pro series represented the high end of Sony's Profeel component television line, designed for enthusiasts and professionals who wanted the best picture quality available. The KX-27HV1 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-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. A remote control (RM-543) is included, which is also compatible with the smaller KX-21HV1.

Related Models

The KX-27HV1 shares its remote control and many design elements with its smaller sibling:

Sony KX-21HV1 - 21-inch version (¥185,000 / ¥188,000 for S variant)

The series was succeeded by the KX-27HV2 in 1989, which added native S-Video support to all models.

Accessories

The monitor was designed to work with Sony's VT-X5R television tuner unit, which could be connected via a single Multi-Connector cable that carried both video and control signals. An optional stand (SU-117) was available that could accommodate both the monitor and tuner.

Included accessories:

Remote commander RM-543
