Introduction and Specifications
In the interest of full disclosure, I’m going to start this piece off with a bit of a confession: Last year, when I was first exposed to NVIDIA’s G-SYNC technology, I turned to one of our contacts at the company and said, “The moment someone comes out with a nice 4K version, I’ll hand over my credit card”. At the time, I had been riding along on a 30” HP display with a resolution of 2560x1600 for a few years, and quite frankly, was itching to upgrade. After all, smartphones and tablets were already available with high-resolution screens that put the pixel densities of typical PC displays to shame. And after years of upgrading every other part of my personal workstation (multiple times), I was yearning for something new and fresh in the monitor market. There really wasn’t anything better available at the time, though.
Save for a smattering of relatively small, 3K and 4K laptop displays, we haven’t quite gotten to the same type of pixel densities on the PC that's currently available on today’s high-end ultra-mobile devices. However, thankfully the monitor space has really heated up as of late, with 4K displays generating a large part of the excitement. Today, we can show you the first 4K display that supports NVIDIA’s G-SYNC technology, the 28” Acer XB280HK. And here she is, in all her UHD glory...

If you take a look at the Acer XB280HK’s specifications above, there are a few things that will stand out. First, obviously, is the display’s resolution of 3840x2160. With over 8MP crammed onto its 28” screen, the Acer XB280HK owners won’t be craving additional sharpness. The display’s response time of 1ms is also very good for a 4K monitor, so ghosting shouldn’t be a concern. The rest of the specifications—except for G-SYNC support—will read much like of the better TN panels out there, however, with brightness, a contrast ratio, viewing angles, and a 60Hz refresh rate that are unremarkable.
