First Impressions
As mentioned, the Optoma UHD55 uses Texas Instruments DMD 0.47 DLP chipset in combination with XPR (Xpanded Pixel Resolution) to perform a four-phase pixel shift in order to resolve 4K resolution images. Optoma also employs an 8-segment RGBWRGBW color wheel, and luckily during my time with the UHD55 I did not experience any rainbows, which is always a potential concern with DLP projectors. Our usual advice applies though: if you know you're sensitive to rainbows, work with a retailer who accepts returns.The UHD55 is rated for 3,600 ANSI lumens and support for wide color gamut of the DCI-P3 color space with the specification of 97% coverage. This is accomplished with use of a filter that engages based on using the WCG picture modes. The specified lamp life hours will vary depending on amount of use and Brightness Mode used. Based on Optoma's specification, the default Bright mode allows for 4,000 hours of use. Eco allows for 10,000 hours and Dynamic will allow for an impressive 15,000 hours. Even when considering that the UHD55 uses a tried-and-true lamp-based light source, the supplied lamp should last many users years before needing replacement unless you are a very heavy user and always run in the brightest mode at all times. When you do need one, replacement lamps cost $235.

Viewing Experience | The UHD55 projector stands out with its extensive range of picture modes, offering versatility for various viewing preferences and environments. With a total of eight SDR modes, two 3D modes, and four HDR modes, users can tailor their viewing experience to suit different content and room conditions. The ability to access ISF picture modes for professional calibration adds an extra layer of customization, allowing enthusiasts to fine-tune the image quality to their liking. The projector provides robust controls for grayscale and color management adjustments, enabling users to achieve a more accurate and pleasing image through detailed settings such as RGB 2-point controls and a Color Management System (CMS). However, the out-of-the-box performance varies across modes, with some exhibiting color biases that may require calibration for optimal viewing. The most suitable modes for dark room settings have been identified, emphasizing the importance of gamma settings alongside brightness adjustments for achieving the best image quality. Overall, the UHD55 impresses with its comprehensive feature set and potential for high-quality image output, although users may need to engage in calibration to maximize its performance. |
