What is AMD FreeSync?

Higher frame rates and smoother image quality

FreeSync is an open software standard for PC games that has been devised by AMD to provide smoother motion and eliminate image tearing, all without reducing frame rates and impacting gameplay. It does this by synchronising the graphics adapter’s frames with the monitor’s refresh rate to ensure that frames from the graphics adapter are displayed on the screen as soon as they are ready.

It’s a feature that is similar to the v-sync setting that can normally be enabled when gaming to prevent tearing, but v-sync has the effect of restricting a game’s frame rate to 60 per second and can impact smoothness. With FreeSync, the aim is to provide the benefits of v-sync, but without restricting the amount of frames per second and overall gaming performance. With FreeSync, the frame rate remains dynamic.

A few things are required in order to take advantage of FreeSync: you need an AMD graphics adapter with DisplayPort Adaptive-Sync 1.2, the latest Catalyst driver (15.2 Beta or better), and you need a monitor that supports the FreeSync standard.

FreeSync is an open standard that makes use of the Adaptive-Sync feature in the DisplayPort specification, and any manufacturer can implement it without charge. So far there are a handful of displays listed as being available from the likes of Acer, BenQ, LG, Samsung, and Viewsonic. AMD claims up to 20 monitors will have the technology in them by the end of 2015.

The current list of AMD graphics adapters and APUs that support FreeSync is as follows:

Is there a competing standard?

NVIDIA has its own standard called G-Sync, but this is a proprietary standard that relies on hardware being installed in a monitor. To make use of that feature, you need both an NVIDIA graphics card, and a monitor that has the G-Sync circuit board installed.

Who is it for?

Technologies like AMD’s FreeSync are primarily for gamers who require the highest frame rates, smoothest image quality, and minimal latency from their input peripherals.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
