Amazon is currently selling Dell's P2715Q 4K Monitor, which is a 27-inch model, for just $359.99. That's a great price for this monitor, seeing as this is typically over $400 and closer to $500. Making this a great pick up for a desk at home or even at work. Especially since this is future proof as a 4K monitor.
The P2715Q is a great monitor from Dell, it is part of its UltraSharp lineup, so you'll be able to use this to get a great picture, but not have to worry about the glare in the background - because there won't be one. This monitor does have a slew of ports in the back, including a couple of USB ports for easy access, or access period if you have a laptop that doesn't have regular USB-A ports anymore. There is of course the usual DisplayPort, HDMI and a few other ports available here. The stand does also come off of the P2715Q so that you are able to mount the monitor. This is a standard VESA mount here, so your existing mount will work just fine with this one. It does work with virtually any computer, seeing as it can be connected over HDMI. This includes Windows, macOS, and Chrome OS. So no matter which laptop you have, this is a great monitor to pick up and extend your workflow.
