ROG is raising the refresh rate to 300Hz represents a 25% increase over the current standard for high-level esports tournaments. At that speed, the screen can draw 5X more frames than the 60Hz panels found on conventional laptops. When your GPU produces enough frames per second to keep up, the faster display makes gameplay silkier than ever before. Higher frequencies can also improve the experience when the refresh rate is fixed and your FPS drops below the maximum. The delay between refresh cycles is shorter, allowing the display to respond faster to fresh frames produced by the GPU. If you’re running Vsync to eliminate visual tearing, the higher frequency mitigates visible stuttering that can occur when the display is forced to wait until the next cycle to show a new frame. At 300Hz, it’s ready to draw a completely new frame every 3.3ms, which nicely matches the 3ms response time of the pixels.

Our IFA panel demos showcase the same technology in multiple segments and sizes. Every frame matters for esports professionals and other competitive players, so we mounted 300Hz displays into 15” and 17” flavors of the Strix SCAR III. These mid-sized machines drive the panels with powerful NVIDIA GeForce RTX 2070 GPUs bolstered by ROG Boost. The cooling system is so effective that we can achieve higher performance by pushing the GPU up to 1540MHz at 115W in Turbo mode, which is technically factory overclocked. While the Strix series puts high refresh rates in their element, our ultra-slim Zephyrus family brings the same technology to premium gaming laptops that blur the line between work and play. We’re showing the same 300Hz panels inside modified versions of the 15” Zephyrus S GX502 and 17” Zephyrus S GX701.
