I'm looking for a new monitor for my workstation and have been warned about the issues with 4k monitors, so will avoid them.  However, some of the options I'm looking at are QHD/WQHD (2,560 x 1,440), and can't find much info on these.  Do they also have issues like the 4k monitors?  Am I best to stick with a 1080p resolution?

Thanks
