It's hard to call any $649.99 item a cheap buy, but Dell's 27-inch stunner is a real bargain at that price, even before Best Buy tosses in either free shipping or a $25 gift card if you pick the display up in-store. The UltraSharp U2711 packs an eye-popping 2560 x 1440 resolution with a 16:9 aspect ratio, 350 nit brightness, ports a-plenty and ultra-wide 178 degree viewing angles. All those pixels would normally cost you between $850 and $1,000.
