ViewSonic LDP217-121C 217” 4K UHD All-in-One Direct View LED Display

Product Overview

The ViewSonic LDP217-121C is a 217" 4K UHD all-in-one direct view LED display engineered for high-impact installations in corporate lobbies, boardrooms, and large auditoriums. As one of the largest commercial-grade dvLED solutions in the LDP Performance Series, it delivers 4K UHD resolution at 1.25mm pixel pitch using advanced Flip Chip COB technology, producing exceptional clarity at viewing distances typical of executive and event spaces. Integrators and facilities teams benefit from its true all-in-one architecture — power, control, image stitching, and display are consolidated into a single SKU, eliminating external processing equipment. The detachable system control bar can be positioned up to 30 feet from the display surface, supporting ADA-compliant installations at under 4" of depth.

Product Description

At 217 inches diagonal, the LDP217-121C commands attention in any large-format AV deployment. The display runs on Android 9.0 with 4GB DDR4 RAM and 32GB onboard storage, and supports Picture-by-Picture from up to four simultaneous HDMI 2.0 inputs — a practical advantage for multi-source control room and command center configurations. COB (Chip-on-Board) packaging mounts LED chips directly to the substrate, producing a flat, gapless surface rated IP54 for dust and moisture resistance and IK08 for impact protection. This durability makes the display appropriate for high-traffic environments including building lobbies and public-facing digital signage installations. Dual 30W speakers are angled toward the audience for consistent audio coverage across large rooms. The display supports wireless content sharing via ViewSonic AirSync (available via OTA firmware update), with native support for AirPlay and Google Cast. LAN control integration with Q-SYS, Crestron, and myViewBoard Manager allows centralized management of multi-display deployments from a single interface. Front-accessible hot-swap LED modules and an included vacuum maintenance tool reduce maintenance time and eliminate the need for rear access. The 3,840Hz refresh rate prevents visual artifacts during video capture, important for broadcast studio and event production environments.
