Morning all, Facing a problem here, as I've just bought a collection of Dell P2815Q monitors for the office. I'd hoped to give the team a bigger desktop to work with, but it seems that the 4K resolution is too high for comfort for some. I'd seen this coming, & for those staff I figured I'd just dial down the resolution to 1440p, which would still be better than a Full HD 24", & not a huge premium over simply buying 1440p monitors. Trouble is I don't seem to be able to get the P2815Q to output at 1440p. My 16:10 options are 1920*1080 or 2048*1152 or 3840*2160. The monitors are connected to Haswell NUC via Displayport, & runnning Windows 8.1.1. Any suggestions on how to achieve a 1440p resolution, or do I either have to live with it or send them back?
