Optoma – with its brand new UHD51A 4K UHD projector, is one of the first projector manufacturers to offer up a smart projector design for the mainstream of the market. This projector is 4K capable using the the smaller/less expensive of the two 4K UHD resolution DLP chips. Meantime, with the UHD51A, you should expect a very sharp image on 1080p and lower resolution content, and even sharper with 4K content. The UHD51A adds other features beyond the Alexa support including frame interpolation (FI), Full 3D support, a built-in USB media player that allows 4K video playback, and support for wireless display from mobile devices with an optional Wi-Fi dongle.
The feature set is better almost all of the other 4K UHD DLPs in the price range, but that’s fair, as it is one of the most expensive using the 1920x1080x4 pixel shifting chip.
The Optoma UHD51A offers very good 4K image that is clean and very detailed, its HDR capabilities are good enough for a projector in this category, it is 3D capable and it has very good overall motion performance. As for connectivity it offers a great variety of ports that surpasses most of the competition. And in all this we should not forget the wealth of features it is equipped with like the built-in media player for example among others in addition to being one of the first projectors that is smart enabled by adding support for Amazon Alexa and Google Assistant.
On the opposite side being a low priced 4K projector means that a few things would naturally not be so good. Black levels in general are so and so and although for many people will be more than enough for image quality fans it will be very obvious. Of course in this price we haven’t seen any 4K projector offering very deep blacks so this is not a problem of the Optoma specifically but seems to be the general standard for this price range. Also brightness although was adequate it measured far less than what Optoma claimed it to be. Input lag was also measured very high making it difficult to suggest this projector for serious online gaming.
