Press release

At the IFA 2019 trade fair in Berlin, ASUS Republic of Gamers (ROG) unveiled its new 300 Hz screens on several gaming laptops from the Strix and Zephyrus series. They display revolutionary display performance that is fast becoming the best on the market. The ROG Zephyrus S GX735 will be the first gaming laptop with a display of 300 Hz to be released in mid-December 2019, followed by many other ROG laptops in the following year.

ROG aims to design the fastest gaming products possible, but also to transform these speeds to offer a more immersive gaming experience. By adopting a display at higher refresh rates than ever, the ROG screens provide a higher number of frames per second: the brand wishes in this way to make its players discover a smoother gameplay than it has ever had. summer, especially on fast action games. These spectacular display performances also give players the advantage during eSports tournaments or competitions.


New display

In 2016, ROG was the first brand to offer refresh rates of 120 Hz on its laptops, in particular the ROG Chimera G752 whose IPS display also features quality colorimetry and a wide viewing angle. The ROG Chimera G752 was the first laptop on the market to offer such high refresh rates. It quickly became the benchmark for PC gaming.

The brand then partnered with Merck in the chemical industry to develop a new liquid crystal structure capable of delivering even higher speeds. This cooperation enabled ROG to present its very first 144 Hz gaming laptops the following year, including the ROG Griffin G703 and the ROG Strix Scar GL503.

In addition to the faster refresh rates that improved the smoothness of the gameplay, the rapid transitions between each pixel helped reduce the motion blur effects of fast moving objects while eliminating sweeping movements. As a result, the images on the screen became sharper, which helped players track their target and stay in a completely immersive gaming environment. The 144 Hz panel offers a response time (gray-to-gray) of only 7 ms, four times less than other gaming laptop screens on the market. In 2018, a new milestone was reached in terms of resolution with response times reduced to only 3 ms which have been applied to a wide variety of gaming laptops running on an Intel Coffee Lake processor.

At CES last January, ROG created the surprise by unveiling its Strix Scar II equipped with a 240 Hz panel. A few months later, the brand distinguished itself by becoming the first to deploy its new generation screens, offering a range of several products such as ROG Zephyrus S GX532, ROG Zephyrus M GU532, ROG Strix SCAR III G531 and ROG Strix Hero III G531. The 17.3-inch models quickly followed on from the 15.6-inch models at Computex 2019 through the ROG Strix Scar III G731.

Each image counts for eSports professionals and tournament players, which is why the higher the refresh rates of their machines, the smoother the gameplay which improves their visual experience on AAA titles. In this perspective, ROG pursues its ambition to offer ever higher frequencies: the brand unveils its 300 Hz screens at the IFA 2019 in Berlin. Among the products that will benefit from this and will be marketed in mid-December 2019 is the new version of the ROG Zephyrus S GX735.

ROG Zephyrus S GX735 Unprecedented speeds

The 300 Hz refresh rate of the new ROG Zephyrus S GX735 is 25% higher than that of conventional gaming laptops currently on the market. At such speeds, the screen is capable of displaying five times more images than the 60Hz panels available on conventional laptops. Combined with a graphics card producing a large number of images per second to maintain its level of performance, this ultra-fast screen streamlines the gameplay in a new way. Furthermore, when it is fixed and the number of images per second is set to the maximum, this refresh rate offers an unparalleled user experience.

As the delay between each refresh cycle is reduced, the screen is able to react more quickly to the images produced by the graphics card. When the system activates the V-Sync feature to eliminate image crashes, the high refresh rate is capable of mitigating the visible effects of jerks that may occur after the screen is forced to wait for the next refresh cycle before posting a new image. At 300 Hz, the refresh rate of the ROG Zephyrus S GX735 is capable of displaying a new image every 3.3 seconds, which goes hand in hand with the 3 ms response time of the pixels.

Multipurpose performance

On the ROG stand at IFA, the same advanced technologies will be unveiled on different prototype machines for different uses, including ROG Strix Scar III in 15 inch and 17 inch format. These medium-sized machines are equipped with a super-fast panel and an NVIDIA® GeForce RTX ™ 2070 graphics card enhanced by ROG Boost technology. The intelligent cooling system is powerful enough to activate the Turbo mode of the card up to 1540 MHz at 115 W, technically overclocked at the factory.

While the Strix series incorporates higher refresh rates, the range of ultra-thin notebooks, ROG Zephyrus, incorporates the same technologies as on gaming notebooks: the line between gaming and professional notebooks blurs. The 15-inch ROG Zephyrus S GX532 and 17-inch ROG Zephyrus S GX735 also incorporate this new 300 Hz panel. Both models have the Switch for exclusive GPU via which the user can switch from G-SYNC ™ mode for smoother games, to Optimus mode which extends battery life.

The Zephyrus S screen is also pre-calibrated at the factory to meet the criteria of PANTONE® certification, offering creators the color precision they need for their work, without sacrificing the display speeds of their games. favorite video.

Cooling an ultra-thin laptop is not easy, which is why the ROG Active Aerodynamic System includes, among other things, an opening when the PC cover is opened, in order to circulate more air in the system. This improved air circulation provides exceptional performance, helping to make the most of the machine’s high refresh rate. Even though it sports an ultra-thin profile, the Zephyrus S is capable of accommodating the powerful GeForce RTX 2070 graphics card with ROG Boost technology which overclock frequencies at levels similar to those of Strix laptops. The Zephyrus S provides superior performance thanks to its GeForce RTX 2080 graphics card overclocked to 1230 Mhz (100 W in Turbo mode), far surpassing the performance of conventional ultra-thin laptops.

Lightning frequencies

The 300 Hz gaming laptops on display at IFA embody ROG’s desire to be a leader in more areas. During the 2019 edition of Computex in Taiwan, ROG announced that it had associated high resolutions and speeds in a 4K UHD 120 Hz screen. This screen is intended for future machines, the ROG Mothership is already available with a 4K UHD panel with 100% Adobe RGB color space.

The special editions of the ROG Zephyrus S GX535 and GX735 are the first to be available in HDR. These models combine high refresh rates with VESA DisplayHDR 400 certification. Their HDR displays can display more than a billion colors and use local dimming backlight technology to provide sharper contrasts. This display technology is so advanced that it ideally requires a common programming interface dedicated to HDR.

However ROG offers many display control options in order to best meet the needs of its users, whether they are hard-core gamers who want the best performance, or content creators who need impeccable display quality.

Towards more and more efficient gaming laptops

The new generation of high refresh refresh rate gaming laptops will be unveiled on the ROG stand at the IFA in Berlin between September 6 and 11, 2019. The 300 Hz technology will be presented in Hall 12 on stand 110 of the Berlin ExpoCenter City -Mass.


The ASUS ROG Zephyrus S GX735 with 300 Hz screen will be available from mid-December in France, from € 2,999 including VAT, recommended retail price, from partner resellers.
