Brightness and Resolution

Comparing the brightness, Optoma UHZ45 comes out on top with 3,800 ANSI lumens versus the Epson 3800’s 3,000 ANSI lumens. When testing, the UHZ45 performed well, with a notably brighter display, perfect for both daytime and night viewing.

In terms of resolution, while the Epson 3800 offers 4K using pixel shifting from its 1920×1080 native resolution, the Optoma UHZ45 boasts true 4K UHD resolution, making images incredibly crisp and vibrant. The UHZ45 clearly wins this round.

Display and Color Processing

The UHZ45 uses a DLP display, while the Epson 3800 utilizes 3LCD technology. Although both offer outstanding quality, the 3LCD technology of the Epson 3800 ensures that the colors are more vibrant and accurate, providing a slightly more superior image quality.

Both projectors boast 10-bit color processing, allowing for a broader range of colors and gradients. In real-life usage, we were impressed by the vividness and color accuracy of both projectors.

Gaming Performance

The Optoma UHZ45 shines in gaming performance. It has an impressive 16.7ms response time at 4K/60Hz and an even quicker 4ms at 1080p/240Hz. The Epson 3800, in comparison, has a slightly slower input lag at 20.6ms at 4K/60Hz and 28ms at 1080p/60Hz. Gaming on the Optoma UHZ45 was a delight, the fast response time made fast-paced gaming smooth and enjoyable.

3D Performance

Both projectors offer Full HD 3D support. However, one customer noted an issue with the UHZ45’s simultaneous DLP-Link and VESA 3D signals, which caused a red tint when using RF 3D glasses. This wasn’t a problem on the Epson 3800, making it the superior choice for 3D viewing.

Lamp Type and Life

One of the major advantages of the Optoma UHZ45 is its laser phosphor lamp, which offers 30,000 hours of life. (Check out our roundup review if you are in search of the best laser projector.) This surpasses the Epson 3800’s 250W UHE bulb, which lasts for 3,500 hours, or 5,000 in Eco mode. We were particularly pleased with the UHZ45’s ability to turn on and off without the need for the lamp to cool down, as highlighted by one of the customers.


Both projectors have integrated speakers with 10.0 Watts x 2. Although neither will replace a dedicated sound system, they provide decent audio quality for casual viewing. However, one customer expressed frustration with the Epson 3800’s lack of sound bar compatibility, which could be a downside for some users.


Optoma UHZ45 connections

Both projectors offer ample connectivity options, including HDMI and USB ports. However, the Optoma UHZ45 takes a slight lead with three HDMI 2.0 ports as compared to Epson 3800’s two. The Epson 3800, on the other hand, offers wireless networking, although one customer found the setup process somewhat complicated.

Lens and Image Size

The Optoma UHZ45 offers a 1.1x manual zoom lens and can project an image size of 33.01″ – 300.15″. On the other hand, the Epson 3800 offers a more generous 1.62x manual zoom and an image size of 39.70″ – 300.40″. The Epson 3800 also offers lens shift, a feature lacking in the UHZ45, providing greater flexibility in projector placement.

Noise and Weight

At full power, the Optoma UHZ45 operates at a quieter 29 dB, compared to the 35 dB noise level of the Epson 3800. It’s also lighter, weighing 10.6 lbs against the Epson’s 15.2 lbs. This makes the UHZ45 easier to carry around and less disruptive during quiet movie scenes.

Additional Features

Both projectors come packed with a range of additional features such as Full HD 3D, Geometric Correction, and HDR. The Optoma UHZ45 is designed for 24/7 operation, an impressive feature that ensures longevity. The Epson 3800, on the other hand, supports HLG and boasts real-time, digital video processing, which enhances its performance.
