Optoma UHD33 4K Overview

If you're in the market for a new 4K UHD projector, the Optoma UHD33 is a solid choice. It features 3,600 ANSI lumens of brightness and a 1,000,000:1 contrast ratio, as well as HDR10 and HLG compatibility. As an added bonus, this projector offers natural color and high-quality images. It also has an integrated Texas Instruments DLP Chipset 7541 and supports a 21:9 aspect ratio. Furthermore, it comes with plenty of connectivity ports.

Another benefit is its low input lag and high refresh rate, which provide an immersive gaming or cinema experience. The 4K resolution also makes for a smooth and lifelike picture with low judder or motion blur. The Optoma is a bit sharper than the BenQ but isn't as lifelike as the LG HU810P.

Another advantage of this projector is its support for HDR, HLG, and tone mapping. This helps improve picture quality in bright and dark scenes. It also offers the option to save the calibration settings so that you can easily adjust the color and contrast settings of the projected image. Additionally, it has two HDMI 2.0 ports for connecting external 4K devices.

Overall, the Optoma UHD33 4K projector has the same contrast ratio as the UHD30, which is acceptable compared to other 4K projectors. However, the contrast ratio of the BenQ is much higher than that of the Optomas. As a result, the BenQ is a better option if you're looking for the highest contrast ratio possible.
