LG's DualUp Monitor is a vertical screen with an unusual aspect ratio
 

LG has revealed a couple of monitors it's debuting at its virtual CES event, and one of them is apparently a completely new format in the market. The company's new DualUp Monitor has an unusual 16:18 aspect ratio. It's a vertical display with a 2,560 x 2,880-pixel resolution that LG is calling "Square Double QHD." When you use its vertical split view function, the DualUp looks like you put two 21.5—inch monitors on top of each other.
