Ease of Installation and Set-Up
You need plenty of space to cast 100” images with either 4K projector. These are not short-throw models, but the UHD38 does allow for ceiling mounting, giving you a more flexible installation. Being able to center the projector on the screen helps with image alignment.
Centering the images is easy with either model. Both offer keystone correction and lens zoom. The ±40° correction on the UHD38 may make it easier to set the projector up over the TK700STi.
Most Flexible Installation: Optoma UHD38
The TK700STi is a 4K projector with a 3,000 lumens lamp and HDR support. You get bright, detailed images in most lighting, but you may need to close the blinds during the day.

When it comes to gaming, it is hard to beat the BenQ projector. Latency speeds are around 16ms for 4K images. Drop the resolution to full HD and input lag is a fast 4ms.
