Introduction
Ultra-short throw projectors are ideal when you have a desk or mounting point less than a few feet from a screen or wall. The Vivitek DU775Z-UST has a 0.25:1 throw ratio, so putting it 50cm away will produce a 2m projected image.
Projectors live and die by image quality because they can lose quality the larger the image gets. Defocusing and distortion are significant problems, but the DU775Z-UST solves them with a Tele-centric lens system.
The Tele-centric lens system delivers constant magnification regardless of the object’s distance or location in the field of view. In other words, it preserves image quality whether you display a 32″ or 150″ image at any angle.
Image quality
Thanks to its Tele-centric lens system, making the Vivitek DU775Z-UST output anything but a perfect image is difficult. The native WUXGA resolution is an industry-standard, and you can display images up to 4K-UHD (3840 x 2160) @ 60Hz.
The high brightness of 5,000 lumens with a 3,000,000:1 contrast ratio ensures images are easily seen in direct sunlight. This projector will do the job splendidly if you have many windows or artificial lighting that saturates regular screens.
Connectivity
How do you get content to the Vivitek DU775Z-UST? It has HDMI, DisplayPort, USB-A, and VGA inputs, allowing content from many wired sources.
Those who prefer to send files over the internet can use wireless connectivity with the included wireless adapter. The wireless connectivity connects to laptops, computers, and tablets for media playback.
Interactivity
The DU775Z-UST has an optional interactive function with an IR Pen & Finger Touch. This technology lets you interact with content and menus without pressing physical buttons, making presentations easier.
Those not bothered by such features can easily operate it with the supplied IR remote control. You also get Vivitek PJ-Control for easy communications and remote control over an IT network, enabling remote functionality.
Eco-friendliness
Laser projectors are eco-friendly, producing 70–80% less heat than non-laser projectors and consuming less energy overall.
The DU775Z-UST is 100% lamp-free and consumes 380W in normal mode, 315W in eco mode, and <0.5W in standby mode. This means it costs less than 20p per hour to run in its most energy-intensive mode at full brightness.
The laser is rated for up to 30,000 hours. You could run it for 1,000 hours per year (or a snip over 83 hours per month) for the next 30 years.
Summing up
The Vivitek DU775Z-UST is an excellent ultra-short throw projector ideal for large displays at close distances. You get an immersive picture with stunning colour and high brightness, courtesy of the 5,000-lumen display.
