Vivitek DH772UST – 1080p 3,500 Lumen Ultra-Short Throw Projector

Product Overview

The Vivitek DH772UST is a 1080p ultra-short throw DLP projector delivering 3,500 ANSI lumens from a 0.33:1 throw ratio, producing an 80–110-inch image from less than 20 inches away from the screen surface. Designed for education and corporate AV installations where space constraints prevent traditional throw distances, the DH772UST eliminates presenter shadow interference and eye-level glare. HDMI 2.0 inputs with 4K signal compatibility, integrated Crestron RoomView networking, and a 12,000-hour lamp life make this projector a practical choice for fixed-installation AV deployments.

Product Description

The DH772UST uses DLP and BrilliantColor technology to produce accurate, shadow-free imagery in ambient-light environments typical of classrooms and training rooms. Its 0.33:1 ultra-short throw ratio allows installation directly beneath or adjacent to the projection surface, enabling large-format display in rooms where a standard throw projector would be impractical. The projector accepts native 4K signal input via dual HDMI 2.0 ports, making it compatible with current-generation sources without requiring signal downconversion.

For AV system integration, the DH772UST includes RS-232 serial control, RJ-45 networking with TCP/IP and Telnet support, and Crestron RoomView compatibility for centralized room management. The built-in 20W stereo speaker system (2×10W) with microphone input supports classroom audio reinforcement without requiring external amplification in smaller spaces. A sealed optical engine and enhanced ventilation reduce dust sensitivity, lowering maintenance overhead in high-use environments. The top-loading lamp access cover simplifies on-site lamp replacement without requiring projector removal from the mount. Anti-theft features include a Kensington lock slot and keypad PIN lock.

Key Features

• 0.33:1 Ultra-Short Throw Ratio — Projects an 80–110-inch image from under 20 inches, enabling large-format display in space-constrained rooms without shadow obstruction.
• 3,500 ANSI Lumens — Delivers clear, bright imagery in rooms with moderate ambient light, suitable for daytime use without full blackout.
• Native 1080p with 4K Input Support — Accepts 4K UHD (3840×2160) signals via HDMI 2.0 while displaying at Full HD native resolution.
• 10,000:1 Contrast Ratio — Produces distinct shadow and highlight detail for presentation graphics and video content.
• Crestron RoomView Integration — Supports TCP/IP, Telnet, and RS-232 for control integration with enterprise AV management systems.
• 20W Built-In Stereo Audio — Dual 10W speakers with microphone input provide classroom-ready audio reinforcement without external amplification.
• 12,000-Hour Lamp Life (Eco Mode) — Extends service intervals and reduces total cost of ownership in high-utilization fixed installations.
• Sealed Optical Engine — Minimizes dust ingress, reducing maintenance requirements in environments with variable air quality.
• Top-Loading Lamp Access — Simplifies lamp replacement without removing the projector from a ceiling or wall mount.
• Anti-Theft Security — Kensington lock slot and PIN keypad lock protect the unit in multi-user or unsupervised spaces.

Typical Applications

• K–12 and higher education classrooms requiring large-format display without rear-projection infrastructure
• Corporate training rooms and conference rooms with limited throw distance
• Government and municipal meeting spaces with fixed AV installations
• House of worship supplemental display areas with space constraints
• Multi-purpose rooms requiring flexible, shadow-free front projection

Technical Specifications

Frequently Asked Questions

What installation distance is required for the DH772UST?

The DH772UST projects an 80–110-inch image from approximately 20 inches (51 cm) from the screen surface, making it suitable for wall-mounted or table-top installation directly adjacent to the projection surface.

Does the DH772UST support 4K content?

The DH772UST accepts 4K UHD (3840×2160) signals via its HDMI 2.0 inputs and displays them at the native 1080p resolution. It does not output native 4K.

Is the DH772UST compatible with Crestron control systems?

Yes. The DH772UST is Crestron RoomView certified and supports RS-232 and TCP/IP control via RJ-45, integrating with most enterprise room control systems.

What audio capabilities does the DH772UST include?

The projector includes a built-in 20W stereo speaker system (2×10W) and a microphone input, providing basic audio reinforcement for small to mid-size classrooms and training rooms without requiring external amplification.

How is the lamp accessed for replacement?

The DH772UST features a top-loading lamp compartment that allows lamp replacement without removing the projector from its mount, reducing downtime during scheduled maintenance.

What warranty does the DH772UST carry for educational deployments?

Vivitek offers an extended education warranty on select models purchased through authorized dealers. Contact Creation Networks or your Vivitek representative to confirm current warranty terms for educational institution purchases.

Does the DH772UST require a filter?

No. Like most Vivitek DLP projectors, the DH772UST uses a sealed optical engine that does not require periodic filter replacement, reducing maintenance requirements in high-use environments.
