Product information
Environmentally friendly short-throw Full HD laser home projector
The energy-saving GT2100HDR laser projector is designed with sustainability in mind, offering easy set-up in any room, with a short-throw lens and extensive connectivity options in a sleek, compact form factor that is up to 34% smaller than previous Optoma models.
This energy-efficient model reduces power consumption by up to 45% compared to Optoma's lamp-based projectors.² Advanced, power-saving DuraCore laser technology provides a long product life of up to 30,000 hours without the need for additional lamps, requires minimal maintenance and is mercury-free, further reducing the environmental footprint.
An added benefit of the GT2100HDR is the external power supply, which provides greater reliability, portability and energy efficiency.
The eco-friendly housing design is made of 50% post-consumer recycled (PCR) plastic and the packaging contains up to 97% recyclable materials.³ The compact size of the GT2100HDR projector reduces packaging, resulting in more efficient logistics and helping to reduce carbon emissions.
The GT2100HDR offers high contrast and accurate, lifelike colour reproduction for movie lovers and delivers a bright 4200 lumens so sports fans can enjoy live action even with the lights on. It also features a gaming mode for low input latency - perfect for games where fast responses are key.
Sustainable development
We strive to reduce the overall environmental footprint of our products to do justice to our planet.
In developing innovative products with sustainability in mind, we consider every stage of a product's life cycle, from design to manufacturing, logistics, use and packaging.
Bright images even in daylight
This all-round home entertainment projector combines high brightness and vibrant colours for a vivid, lifelike picture in brightly lit environments - ideal for TV shows, sports and movies or gaming with family or friends at any time of day.
Laser Technology
Optoma laser projectors use only high-quality laser technology to project the best possible image. In many situations, the perceived brightness of laser projectors can be twice that of a conventional lamp model. They also provide greater efficiency to ensure uniform brightness. In addition, they provide for superior colour performance, instant on/off and an exceptional lifespan of up to 20,000 hours.
Short distance projection
This projector can project large images from a short distance, meaning you can achieve an image up to 100 inches in size from just under a metre away.
Full HD 1080p
1080p resolution delivers crisp, detailed HD images - all without downscaling or compression. This makes it perfect for watching Blu-Ray movies, HD television broadcasts and for use with gaming consoles.
HLG compatible
Suitable for receiving and displaying Hybrid Log Gamma (HLG) HDR content. HLG compatible projectors from Optoma allow you to see even more detail and textures. Objects look more solid and lifelike and the extra detail gives more sense of depth. It's like looking through a window. (UHZ65UST and P2 via USB only)
Saturated colours
Whether it's movies, TV shows or video games: Optoma projectors deliver stunningly rich colours in any environment and for any content. Our home theatre projectors work with the Rec.709 colour scheme, the international HDTV standard, to ensure accurate colour reproduction.
Gaming Mode
Gaming Mode prepares your projector optimally for gaming: Maximum contrast, impressive response times and lifelike colours capture every detail - so you can focus on winning.
Dual HDMI inputs
Play games, stream videos and share photos on the big screen in the comfort of your home. Dual HDMI inputs let you easily connect your game console, set-top box, laptop, PC, Blu-ray player or media streamer with a single cable. By connecting an HDMI dongle such as Google Chromecast™, Amazon Fire TV, Apple TV™ or Roku® stick, you can even turn the unit into a smart projector.
360 degree projections
Images can be projected along the horizontal axis over 360 degrees.
Automatic power off function
It may happen that the projector is on although it is not needed. To save energy in these cases, the auto power off function ensures that the projector is switched off after a pre-set time.
24p
Most movies are shot at 24 frames per second (fps). Optoma projectors can recognise HD sources and play back movies at 24 fps as the director intended.
