At an Nvidia press briefing earlier today, the company had one of Acer's latest 4K Ultra HD panels on hand to show off their G-Sync technology. As we've covered before, the XB280HK is a 4K LED-backlit LCD monitor designed for gamers, supporting a 60 Hz native refresh rate over DisplayPort 1.2, and packing Nvidia's aforementioned adaptive refresh rate technology.
Acer's 4K panel looks great from a picture quality perspective, as you'd expect from a monitor boasting a huge 3840 x 2160 resolution. The demo shown on the display looked sharp and well detailed, and viewing angles seemed pretty good.
While the display itself is quite good, obviously the main selling point is the Nvidia G-Sync chip integrated into the panel. Computex 2014 is the first time I've had eyes-on with G-Sync, and I've got to say, the technology is extremely impressive. When the GPU was rendering a game at 40 frames per second, the low-ish frame rate was hardly noticeable with no stutter, lag, tearing or strobing; it looked just as good as if you were gaming at 60 frames per second.
Adaptive refresh rate technology is crucial for gaming at 4K because it's unlikely your graphics card will be capable of playing all games, at high levels of detail, at frame rates at or above 60 FPS. Getting a monitor such as Acer's XB280HK will allow you to set in-game details as high as possible, while still keeping gameplay smooth due to the G-Sync chip, provided you have an Nvidia GPU.
At Computex 2014 I also spotted AMD's competing technology, FreeSync, on show at their booth. I'll have more on FreeSync later.
