Optoma's latest projector is rated to throw a 100-inch image from just about a foot (0.3 meters) away at up to 3,800 lumens: brighter than the preceding UHZ55. However, the newer GT3500HDR can only output in 1080p.
It also has an "enhanced" Gaming Mode backed to achieve a latency of up to 4 times "lower than the competing display technology" (that goes specified by Optoma). It is 8.6 milliseconds (ms) at 120Hz (although that drops to 17ms and 60Hz when the input is 4K/UHD)...although the older UHZ35ST is rated for a 240Hz refresh rate.
The GT3500HDR is another of Optoma's dual-HDMI 2.0 projectors with a lifespan of up to 30,000 hours thanks to DuraCore laser technology. However, it stands out with an updated build made of 50% post-consumer plastic that is 28% smaller than its GT5600 predecessor and has an official IP6X rating.
The GT3500HDR has been released to B&H Photo at $1,499, although it is currently priced at $1,272.30 on Amazon in its 500,000:1 contrast ratio variant.
