Review on Experience the Ultimate Display with Dell's Led Lit U4919DW Monitor: Curved, 60Hz, HD by Dave Brummet

Great monitor. If you are talking about dual monitors with a lower/lower resolution, this is the best option. Not only does it give you an uninterrupted screen area with no center bezel, it also charges your laptop via Thunderbolt 3 at 90W, acts as a hub for keyboard/mouse and other USB devices, and sends a 5k video signal to the monitor via on single cable. Be aware that if your computer/laptop is old it might not support 5k resolution or only use it with certain connection types like Displayport, HDMI Thunderbolt 3 etc. Several people have given this monitor bad reviews because their laptop is not capable of driving this display, or they are using the wrong type of video connection to the monitor. There's nothing wrong with the monitor, it's just folks who didn't do their homework before buying it, and likely with the right adapter and cable combo they'll probably be able to run it in all its 5k glory most of the time.
