Samsung Display has developed a quantum dot organic light-emitting diode (QD-OLED) that, for the first time for a monitor panel, simultaneously achieves 4K resolution and a 360 Hz high refresh rate. The product will be unveiled for the first time at Computex 2026 in Taipei, Taiwan, in June.
Samsung Display said on the 28th that it plans to showcase a 31.5-inch 4K 360 Hz QD-OLED for monitors to clients and media at Computex 2026, which runs from the 2nd to the 5th next month. Until now, there have been monitors that support 4K resolution or refresh rates of 360 Hz or higher, but this is the first time both specifications have been achieved simultaneously.
To achieve 4K resolution, it has been common to lower the refresh rate to 240 Hz or less, or to lower the resolution to quad HD (QHD) to achieve a high refresh rate of 360 Hz or higher. To achieve both high resolution and a high refresh rate at the same time, the amount of pixel data that must be processed per second surges, increasing pixel charging time and the burden on the driving circuitry.
As games with near-photorealistic graphics and ultra-high-definition video content have increased and demand has grown for monitors that deliver both high resolution and fast screen transitions, Samsung Display has focused on developing a QD-OLED monitor that combines 4K and 360 Hz. The company said it overcame technical limits by optimizing the panel circuitry and driving system.
Beyond its ultra-high resolution and ultra-high refresh rate, the new product strengthens key performance areas such as dual mode, high brightness, and text readability. Applying the "dual mode," which allows users to adjust resolution and refresh rate depending on the usage environment, lets users lower the resolution to full HD (FHD) while raising the refresh rate to as high as 680 Hz. A Samsung Display representative said, "When 'dual mode' is applied, it can run at an ultra-high refresh rate of up to 680 Hz, enabling smooth, sharp visuals without stutter even in FPS (First-Person Shooter) gaming environments where instantaneous response speed is critical."
This product is the first monitor panel to receive the Video Electronics Standards Association (VESA) DisplayHDR™ True Black (TB) 600 certification. The certification comprehensively evaluates dark-scene rendering performance and HDR brightness, indicating it achieves higher luminance than existing premium self-emissive monitors. To earn the True Black 600 grade, black must be expressed at 0.0005 nits or less, and not only white but also the combined brightness of red, green, and blue must each reach a maximum of 600 nits or higher.
The new product also features the "V-Stripe" pixel structure, a new technology released this year. V-Stripe is a structure in which red, green, and blue (RGB) subpixels are arranged in vertical stripes. The company said it more clearly renders the edges of characters, making it suitable for users sensitive to text readability, such as those doing document work, coding, and precise graphics and content creation. Regarding supply of the 31.5-inch 4K 360 Hz product, Samsung Display is currently in talks with about 10 global clients. Full-scale mass production is set to begin in the second half of the year.
Executive Director Jeong Yong-uk, head of strategy marketing for the large display business unit at Samsung Display, said, "Many clients are evaluating the 31.5-inch 4K 360 Hz new product as a near-perfect monitor that satisfies everything consumers expect from premium monitors, including ultra-high resolution, ultra-high refresh rate, high brightness, and readability," adding, "We will continue to introduce innovative products that exceed market expectations through the inherent picture quality excellence of QD-OLED and relentless research and development."
