BenQ CineHome HT2550  review Affordable 4K projector proves resolution isn't everything The BenQ HT2550 is one of the least expensive 4K projectors available. It actually produces full 4K resolution onscreen, and its image is slightly sharper than you get from non-4K projectors. Initial color is relatively accurate. The sharpness benefits of 4K are minor, even on a huge screen. Worse contrast than some competing projectors, and poor HDR image quality.   Although it lives up to the 4K promise for an affordable price, the BenQ HT2550 lacks the overall performance to beat the competition -- at both 4K and 1080p. rojection fans have been waiting for 4K resolution to come down in price for years,  and it's finally happened . Thanks to a new generation of DLP chips, you can finally enjoy all of the pixels of 4K TV shows and movies without paying a fortune. The BenQ HT2550 ($1,500) is one of the least expensive 4K projectors available, and it's really good. Fi...

Planet Computers Gemini hands-on review There is something happening in the mobile industry. Companies are noticing there is an audience for nostalgic, retro-themed devices. HMD Global has leveraged the Nokia brand to great effect with its Nokia  3310  and  8110 4G  phones, and  BlackBerry  is exploiting the desire to standout from the crowd by combining strong hardware with the same desirable core values that originally built the brand. The latest to follow the trend is Planet Computers’ Gemini, a Personal Digital Assistant (PDA) which drags a style populari z ed by Psion and  Ericsson  in the ‘90s into 2018. The trouble is, 2018 isn’t utterly convinced the PDA wants to come back at all. Here’s the good stuff. It’s a well-engineered piece of tech made by a team with a lengthy history in the mobile industry, a clear love of the PDA design, an understanding of what makes a good one, and the kind of geeky appeal many will ado...
