One of the best aspects of PC gaming is that you don't need high-end hardware to have fun. Sure, buying a premium gaming monitor will unquestionably give you a more enjoyable experience in whatever you play, but they're not always necessary. If you're looking for a basic display that still looks good, or you just want a second (or third, or fourth) display for your existing setup, you might be interested in this deal.
B&H Photo is currently selling the ASUS VP239H-P 23-inch monitor for just $89.99, a savings of roughly $30 from the usual price (it's $120 at Amazon right now). It's a fairly basic monitor, only offering a 1080p resolution with a 60Hz refresh rate, but that's to be expected for under $100.
The main selling point of this monitor is the IPS (In-Plane Switching) display panel, which offers better colors and improved viewing angles compared to monitors using TN (Twisted Nematic) panels. Most other displays around this price use TN.
