Walmart offers the Dell UltraSharp U2417HWi 23.8" 1080p Wireless Connect IPS LED-Backlit LCD Monitor for $219.76 $213.70. Opt for in-store pickup to drop that to $216.71 $210.73. (Amazon charges the same with free shipping.) That's the lowest price we could find by $6 (most stores charge over $250) and the best outright price we've seen. (We saw it with a $50 gift card for $247 last month.)

This monitor allows you to wirelessly display and edit from two mobile devices on a single screen. It features a 1920x1080 (1080p) native resolution, 802.11ac wireless, 5-port USB 3.0 hub, HDMI, and height-, pivot-, tilt-, and swivel-adjustable stand.
