Product Preview

In November of 2021, Optoma released the feature-loaded long-throw UHZ50 4K Laser projector to its product line-up. As a follow-up, Optoma is adding another projector with similar features, the UHD55. However, instead of a laser light source, it incorporates a traditional lamp. This means that over long-term ownership, users will need to replace the lamp at least once, but the trade-off is that the projector is a little less expensive. 

That being said, this projector offers a lot of flexibility for home entertainment, gaming, and even classroom or business presentation.

Let’s check out what this 4K UHD Home Cinema Projector offers to see if might be right for you. 

How the Optoma UHD55 Does 4K

The UHD55 employs a .47-inch 1080p resolution DLP imaging chip (aka DMD – Digital Micromirror Device) from Texas Instruments. The chip contains 2.1 million pixels (very tiny mirrors). However, for the projector to display 4K, 8.3 million pixels are required. To achieve this the pixels on the 1080p chip are shifted both vertically and horizontally at 240Hz (240 times per second), which is so fast it is classified as a 4K image once displayed on the screen.
