Optoma UHZ50 4K Laser Projector Does A Lot More Than You Think

If you are looking for a traditional style video projector, but updated with the latest tech, such as 4K resolution, laser light source, and smart features, the Optoma UHZ50 is worth checking out.

Optoma UHZ50 Laser Projector Lifestyle

It wasn’t that long ago that video projectors were a high-end home theater luxury that just allowed you to watch DVDs and Blu-ray discs on a large screen. 

However, as years have progressed, video projectors have increased in quality, with many now supporting 4K UHD resolution, eliminating lamps, providing more flexible installation options, and incorporating content access capabilities that don’t always require plugging in an external source. All of this plus decreasing prices makes a video projector a viable alternative to an expensive large screen TV

One example of the latest generation of video projectors is the Optoma UHZ50.

How the Optoma UHZ50 Does 4K

The UHZ50 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.

The UHZ50 Laser System

The UHZ50 employs a laser light source, which eliminates the need for a lamp that would have to be replaced on a periodic basis. The UHZ50 laser system has an expected lifespan of 30,000 use hours

According to Optoma, a hybrid Laser/Phosphor light source is used in the UHZ50. In this system, a single laser emits blue light. The Blue light beam passes through a phosphor color wheel where a yellow light beam is created. The blue and yellow light beams then pass through a filter wheel (aka color wheel) where the yellow beam is used to create red and green light beams to complement the blue light beam.

The resultant blue, red, and green light beams then travel through the rest of the light engine, where the colors are combined as needed, reflected off the DLP chip, and projected through the lens onto the screen.

Optoma DuraCore Technology

The UHZ50 laser system is a part of Optoma’s DuraCore-branded Technology, which includes the following:

  • Stable Brightness and Color – The laser light source maintains stable operation over its entire life with no gradual decay. No periodic lamp replacement is needed.
  • Quick On/Off – The laser light source does not require any “warm-up” time when turned on and cool downtime is shorter in comparison to lamp-based projectors 
  • Eco-Friendly – The laser light source is Mercury-Free.
  • IP6X Certification – The UHZ50 features an airtight optical engine with IP6X certification. The airtight enclosure prevents dust particles from entering and ensures long-lasting reliable performance.

    I just got this – the only audio pass through it does are 5.1 and 7.1. Is it possible to know how you came to have it pass through atmos please?

    In order to access Atmos and DTS:X you need to have the projector connected to your external audio system via HDMI-eARC – not Digital Optical. Also, the Dolby Atmos/DTS:X source needs to be connected to HDMI input 3. Of course, the content source has to be providing an Atmos or DTS:X signal. There would be no reason for the projector to provide HDMI-eARC if Atmos and DTS:X weren’t supported – if it isn’t then Optoma has some explaining to do.
