What is G-SYNC Ultimate?

Here’s everything you need to know about G-SYNC Ultimate and the differences between it and the newly-announced G-SYNC and G-SYNC Compatible.

What is G-Sync?

As noted in our previous feature, NVIDIA’s G-SYNC is a hardware-based technology that manages and manipulates the vertical blanking interval of a display panel in order to create a smoother gaming experience. It’s intended to reduce and eliminate a phenomenon called screen-tearing.

In the past, NVIDIA promoted and positioned G-SYNC as a single, binary qualification. Either a monitor was compatible or it wasn’t.

In 2019, NVIDIA has expanded the program to include three categories that each reflect a different level of G-Sync functionality.

A table that roughly outlines the differences between the three types of G-Sync experience can be seen below.

What is the difference between a G-SYNC and G-SYNC Compatible Monitor?

The difference between a G-SYNC and G-SYNC Compatible monitor is simple. The former represents more-or-less the experience that G-SYNC has previously been known for. If you’re using a G-SYNC monitor, you can expect reduced input lag and screen tearing on variable refresh rate outputs.

Then, G-SYNC Compatible monitors refer to any monitor that provides what NVIDIA call a ‘Validated Experience’. By this, they mean that NVIDIA has gone and tested the monitor in question and found that these it doesn’t produce any blanking, pulsing, flickering, ghosting or other artifacts during variable refresh-rate output.

NVIDIA’s testing for G-SYNC Compatible monitors also involves making sure the monitor can deliver a variable refresh rate range of at least 2.4:1 and whether these capabilities are enabled by default. If it meets the above criteria, NVIDIA will stick a badge on that monitor that lets consumers know its G-SYNC Certified.  

Nvidia have a full list of G-SYNC Compatible monitors on their website here.

What is a G-SYNC Ultimate Monitor?

As the chart above lays out, G-SYNC Ultimate monitors are those that NVIDIA rates as offering “the best experience” when it comes to image quality, color accuracy, variable refresh rate performance and high dynamic range with over 1000 nits of brightness.

Like G-SYNC monitors, Ultimate displays are also required to have passed over 300 compatibility and quality tests. They also incorporate a more advanced processor.

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.
