It’s not easy choosing a projector when both offer many of the same features. Here’s a closer look at both Optoma models so you can make an informed decision.

Image Quality

How images look onscreen is key when you’re looking at home theater projectors, and neither one will disappoint you. You get HD resolution and HDR10 support for bright, detailed images. The GT1080HDR has a 50,000:1 contrast ratio. Blacks are rich, even when the lights are on.

Even though you can’t complain about image quality with the GT1080HDR, you do get a brighter picture with the GT1090HDR. It has a higher lumens rating at 4,200, compared to the 3,800 lumens from the other Optoma projector. The 300,000:1 dynamic contrast ratio is also a noticeable difference, especially between blacks and whites.

Ease of Installation

The throw-distance is the same for both projectors. You only need a foot or so of space between the lens and screen to enjoy 100” images. Digital keystone correction and zoom make it easy to center the picture.

However, the GT1090HDR does make it easier to align the onscreen picture. It has instant corner correction that automatically centers the image. All that’s left for you is to fine-tune the picture to your preferences.
