5K x 2K. Dell UltraSharp 40-Inch Curved WUHD Monitor: U4021QW | Dell USA Was considering the 4x ultra super wide 1440 style: Dell UltraSharp 49 Inch Curved Dual QHD Monitor: U4919DW | Dell USA But the 2k extra height is nice. Not enough to get another complete chart in there, or stack charts, but tall enough to get great context. Although they said Aug delivery, it came in 2 weeks. Ordered another one today, for another location where I trade. Can't haul it around! BTW: great color too for watching a movie. Also no dead pixels etc. FWIW.
