Acer launches what it claims is the first 4K/UHD resolution monitor featuring Nvidia G-Sync technology-- the XB280HK, a 28-inch LED backlit display promising smooth, tear-free imagery for your customers' PC games.

The display handles resolutions of up to 3840 x 2160, and features flicker-less, low dimming and ComfyView technology to help reduce eye strain. Connectivity comes via DisplayPort v1.2 and four USB 3.0 ports.

An adjustable stand allows tilting from -5 to 35-degrees as well as 120-degree rotation. Viewing angles are 170/170-degree.

An ex-Google product manager invents the "Robo-Projector." He calls it Keecker and it is a rolling robot with a video projector that can sync with smartphones to turn any wall into a screen for watching movies, checking email, and more.

This is R2D2 if designed by Apple. Keecker frees the screen from its fixed spot. Keecker lets home users watch content anywhere there's enough wall space and no stairs (robots can't climb, yet).

Bill Gates has invented his own home system that allows him to control the photos on screens throughout his home, like a personal digital signage system. Now anyone with Keecker can bring video or photo content to any room, any place, any time.

The Oculus Rift is not the only contender in the virtual reality headset arena-- Sony uses the Game Developer Conference 2014 event to unveil "Project Morpheus," a VR headset prototype for the Playstation 4.

"Nothing elevates the level of immersion more than VR,” Sony Computer Entertainment head Shuhei Yoshida says. “Many of us in PlayStation have dreamed of VR and what it can mean to the games we create.”

Morpheus builds on earlier Sony developments in headset (or "Personal 3D Viewer") space, with a 1080p LCD offering a 90-degree field of view and "uniquely developed" 3D audio technology. Aditionally it promises "seamless" PS4 integration-- the Playstation Camera pairs with built-in sensors to take care of head tracking, while the Move peripheral handles game control.

BenQ launches two gaming monitors armed with Nvidia G-Sync technology at CES 2014-- the 24-inch XL2420G and 27-inch XL2720G, both promising to eliminate issues of the image tearing, stuttering and latency variety.

The monitors also feature RevolutionEyes, a BenQ technology providing more comfortable viewing with ZeroFlicker (eliminates LED flicker issues), Black Equaliser (adjusts brightness without over-exposing white levels) and Low Blue Light (automatically adjusts blue light emissions) capabilities.
