LG 43UN700

With two of these monitors in a horizontal/vertical config, that's right about 60" wide. You'd need a good size desk, like THIS or THIS to comfortably fit the LG's and a laptop. You could get away with a 63" desk, but the 70" + desks will better suit your setup. If you wantd to construct a desk, you could always go with an IKEA setup, using Alex drawers and one of their Karlby 74" or 98" countertops. If you go with the larger 98" be sure to grab an extra OLOV adjustable desk leg or two to support the center of the countertop so it doesn't droop over time from the weight of your monitors.
