All three projectors are updates to previous Optoma models, but the GT1090HDR and HZ39HDR in particular have a major change from the GT1080HDR and HD39HDR. They are the first Optoma gaming projectors with a DuraCore laser light engine. The upgrade from a traditional lamp to laser light source means the GT1090HDR and HZ39HDR are virtually maintenance free and require no lamp replacements for the life of the product. Laser life is rated for 15,000 hours at full brightness or 30,000 hours in Eco mode.
The GT1090HDR has a rated light output of 4,200 ANSI lumens and a contrast ratio of 300,000:1 with Extreme Black enabled. This is up from 3,800 lumens and a contrast ratio of 50,000:1 on the GT1080HDR. The HZ39HDR sees the same increase in contrast ratio (300,000:1 with Extreme Black) although the same 4,000 ANSI lumens output from last year.
To further excite gamers, the projectors support 120Hz refresh rate and with Enhanced Gaming Mode; input lag times are in flat-panel TV territory with 16ms at 1080p/60Hz and 8ms at 1080p/120Hz. (Full support of these features will be available early in the second quarter with a firmware update.) Both projectors will accept a 4K input over HDMI 2.0 with HDCP 2.2. There is a second HDMI 1.4 input on each. HDR10 is supported on both with the addition of HLG support on the HD1090HDR.
Setup options are more flexible on the HZ39HDR, with a 1.3x optical zoom that allows for a throw ratio range of 1.21-1.59:1 and a projection size from 28 inches all the way up to 300 inches diagonal. The GT1090HDR has a fixed zoom with a short throw ration of 0.5:1 and can also display an image up to 300 inches diagonal. The projectors have two built-in 10W speakers and both support Blu-ray 3D.
Alongside the GT1090HDR and HZ39HDR is the HD28HDR, which has many of the same features at a lower price. The HD28HDR uses a traditional lamp light source for a rated brightness of 3,600 ANSI lumens and a 50,000:1 contrast ratio, with an expected lamp life of 4,000 hours at full power or a long 15,000 hours on Eco. It will accept a 4K and HDR10 signal. Enhanced Gaming Mode delivers the same low input lag performance as the GT1090HDR and HZ39HDR. The throw ratio of 1.47-1.62:1 and 1.1x optical zoom allows for some flexibility in projector placement.
