ViewSonic has released the new VX2880ml, a 4K monitor that features a 28” display with 3840×2160 Ultra HD resolution. This is 4 times the resolution of standard HD which means that the VX2880ml delivers a sharp picture with deep colours. This monitor would be ideal for digital signage due to the fact that screens can easily be daisy chained thanks to the 2 DisplayPort inputs and the 1 DisplayPort output. This means that you could daisy chain 4 together to make a smaller video wall or if not this device would be more than suitable as a single smaller screen. Also, due to its high resolution it would be much more likely to catch the eye of a passing customer. The VX2880ml also features MHL functionality which makes connecting with a compatible mobile device much easier.
