Vivitek DK2688 4K UHD and DH678 1080p Home Theater Projectors at Infocomm 2018 – Video Posted on August 20, 2018 By Nikki Zelinger The Vivitek DK2688 is a DLP projector with 4K UHD resolution. This projector is a high-brightness version of the Vivitek HK2288 projector that we reviewed earlier this year. At 4,000 lumens, it can be used in a bright living room or media room where there is little to no control over ambient light. It has a $2,499 list price, making it highly competitive with other 4K UHD projectors on the market, especially with that higher lumen count. This projector has three HDMI inputs instead of the usual two seen from most other manufacturers. That extra HDMI port goes a long way when needing to connect multiple devices to the projector, such as a game console (or two), and a 4K UHD player or Apple TV, etc. The third HDMI can, in some cases, eliminate the need for a switcher, saving you a couple extra dollars that can be better spent on growing your 4K UHD movie collection. The second projector featured in this video is the Vivitek DH678. This is a laser-based 1080p projector claiming 4,000 lumens, making this one ideal for bright rooms as well. Also at a $2,499 list price, the DH678 is a projector to consider for those who do not want or need a 4K UHD projector, though given the choice, I would personally always choose the higher resolution. These two projectors were unveiled at Infocomm 2018, and both can be used for business and education applications as well as in the home. They are so new that there are no available specs on them other than what we learned at Infocomm. Enjoy the video! Subscribe to our YouTube channel to be the first to know when a new video goes live!
