G-SYNC

Technology

See gaming differently with breakthrough NVIDIA® G-SYNC™ display technology.

By synchronizing the display refresh rates to the GPU, G-SYNC eliminates screen tearing and minimizes stutter and input lag to deliver the smoothest, clearest and most breathtaking gaming experience possible.

When every frame matters, you want the phenomenal visual performance only NVIDIA G-SYNC can deliver. Scenes appear instantly. Objects look sharper and more vibrant. Gameplay is fluid and responsive to give you faster reaction times, and a competitive edge. Every game looks, plays, and feels the way it should.

The Problem: Old Tech

When TVs were first developed they relied on CRTs which work by scanning a beam of electrons across the surface of a phosphorus tube. This beam causes a pixel on the tube to glow, and when enough pixels are activated quickly enough the CRT can give the impression of full motion video. Believe it or not, these early TVs had 60Hz refresh rates primarily because the United States power grid is based on 60Hz AC power. Matching TV refresh rates to that of the power grid made early electronics easier to build, and reduced power interference on the screen.

By the time PCs came to market in the early 1980s, CRT TV technology was well established and was the easiest and most cost effective technology for the creation of dedicated computer monitors. 60Hz and fixed refresh rates became standard, and system builders learned how to make the most of a less than perfect situation. Over the past three decades, even as display technology has evolved from CRTs to LCD and LEDs, no major company has challenged this thinking, and so syncing GPUs to display refresh rates remains the standard practice across the industry to this day.

Problematically, GPUs don’t render at fixed speeds. In fact, their frame rates will vary dramatically even within a single scene of a single game, based on the instantaneous load that the GPU sees. So with a fixed refresh rate, how do you get the GPU images to the screen? The first way is to simply ignore the refresh rate of the display altogether, and update the image being scanned to the display in mid cycle. This is called ‘VSync Off Mode’ and it is the default way most gamers play. The downside is that when a single refresh cycle show 2 images, a very obvious “tear line” is evident at the break, commonly referred to as screen tearing. The established solution to screen tearing is to turn VSync on, to force the GPU to delay screen updates until the display cycles to the start of a new refresh cycle. This causes stutter whenever the GPU frame rate is below the display refresh rate. And it also increases latency, which introduces input lag, the visible delay between a button being pressed and the result occurring on-screen.

Worse still, many players suffer eyestrain when exposed to persistent VSync stuttering, while others develop headaches and migraines. This drove us to develop Adaptive VSync, an effective, critically-acclaimed solution. Despite this development, VSync’s input lag issues persist to this day, something that’s unacceptable for many enthusiasts, and an absolute no-go for eSports pro-gamers who custom-pick their gaming hardware to minimize the life-and-death delay between action and reaction.

The Solution: NVIDIA G-SYNC

Enter NVIDIA G-SYNC, which eliminates screen tearing, while minimizing input lag, and stutter. G-SYNC achieves this revolutionary feat, by synchronizing the display to the output of the GPU, rather than the GPU to the display, resulting in a tear-free, faster, smoother experience that redefines gaming.

Industry luminaries John Carmack, Tim Sweeney, Johan Andersson and Mark Rein have been bowled over by NVIDIA G-SYNC’s game-enhancing technology. Pro eSports players and pro-gaming leagues are lining up to use NVIDIA G-SYNC, which will expose a player’s true skill, demanding even greater reflexes thanks to the unnoticeable delay between on-screen actions and keyboard commands. And in-house, our diehard gamers have been dominating lunchtime LAN matches, surreptitiously using G-SYNC monitors and laptops to gain the upper hand.

If, like eSports pros, you want the clearest, smoothest and most responsive gaming experience possible, NVIDIA G-SYNC monitors and laptops are game-changers, the likes of which cannot be found anywhere else. A true innovation in an era of iteration, NVIDIA G-SYNC will redefine the way you view games.
