Affordable G-Sync: AOC G2460PG
Variable-refresh displays have a reputation as luxury products, but AOC's G-Sync G2460PG proves that you don't have to spend a ton of money to get into the game. This 24" display offers a 144Hz maximum refresh rate, a USB hub, and a stand with height and tilt adjustments. The 1920x1080 resolution on this display should make it easy to drive with affordable graphics cards like the GeForce GTX 1060.
Going bigger: Dell S2716DG
If you're looking for something a little more grand than a 24" monitor, you needn't look further than the Dell S2716DG. This stylish 27" display offers thin bezels, a 144Hz refresh rate, a USB hub, and a fully-adjustable stand. Dell covers the S2716DG with a three-year warranty with advance exchange, too (meaning Dell will ship you a new monitor before you turn yours in). We're fans of Dell's offerings overall for their build quality, and we expect the S2716DG to deliver.
The monitors above do use TN panels. We think that's fine for their relatively affordable price points. TN panels have gotten a lot better over the past few years, and something has to give if you're not going to pay way over $600 for a G-Sync display. For folks who don't need to edit images or media on a regular basis, these monitors appear to be decent enough performers out of the box. In the unlikely event someone will stick a calibrator on the front of these displays, they seem to snap into sRGB conformance just fine. Tom's Hardware got good results from calibrating the G2460PG, and we'd expect similar performance from the Dell S2716DG.
King of the 27" G-Sync hill: Asus PG279Q
Asus' PG279Q is among the finest gaming monitors we've ever laid eyes on. It uses a 2560x1440 IPS panel with a 144Hz refresh rate, and it keeps gray-to-gray response times to 4ms. If 144Hz isn't fast enough already, an option in the PG279Q's menus lets owners overclock the screen to 165Hz. For games like Counter-Strike: Global Offensive that can run at those kinds of frame rates, the PG279Q is unparalleled in its smoothness and responsiveness. For $800, we'd expect that kind of awesomeness, but it's still something to behold. The IPS panel offers great viewing angles and accurate colors, too.
Nvidia's G-Sync tech means that the PG279Q remains buttery-smooth across a broad range of frame rates. Unlike some FreeSync displays, the PG279Q can do the variable-refresh dance across its entire 30- to 144-Hz (or 165-Hz) range, no questions asked. That range is helpful in titles like Grand Theft Auto V where maxing out the eye candy can be challenging for today's graphics cards.
One word of warning: some PG279Q owners have complained that they've had to play the panel lottery with this display. Some PG279Qs seem to be fine, while others reportedly exhibit backlight bleed and regions of poor color consistency. Picky buyers may need to be prepared to complain to Asus customer service if their display isn't up to snuff.
4K and G-Sync: Acer XB271HK
If you're looking for the rather exclusive combo of G-Sync and a 4K resolution, consider Acer's XB271HK. This 27" IPS display offers a 4K resolution and G-Sync support, all wrapped in a neat-looking package. Acer says the average response time should be around 4ms. The maximum refresh rate is 60Hz, and the monitor includes a USB hub and a pair of 2W speakers. The included stand is fully adjustable, too.
Curved G-Sync: Asus PG348Q
If you want to get a curved, ultrawide, high-refresh-rate monitor with G-Sync, the gorgeous Asus PG348Q wraps all those features into one neat package. This monitor uses a 100Hz, 34" IPS panel with a mild 3800R curve. While the PG348Q may be the display your eyes have always dreamed of, the $1300 price tag may leave them full of tears. Newegg does throw in an LG projector with the monitor right now, though, which might soften the blow.
