The latest MSI Flagship QD-OLED gaming monitor


MSI, the world’s leading manufacturer of true gaming hardware, is proudly expanding the hardware possibilities for all gamers. Since the MEG 342C QD-OLED's first leak in 2022, MSI continuously fine-tuned every aspect of it for a better gaming experience. Now, we're proudly announcing our MEG 342C QD-OLED is finally ready.

The 34-inch QD-OLED panel is an incredible combination of Quantum Dot technology and OLED panel that exhibits the best picture quality with a perfect pixel lighting control that presents a true black scene. The HDR peak brightness is leveled up to 1000 nits, passing the VESA DisplayHDR True Black 400 certificate and providing the ultimate immersive gaming experience with a super-fast 0.1 ms response time and 175 Hz refresh rate.


The color performance is further enhanced by quantum dot technology unlike other OLED monitors. The color volume reaches 97.8% Adobe RGB, 99.3% DCI-P3, and 139.1% sRGB with the most vivid colors in default Premium Color Mode. In professional mode with a DELTA E value of less than 2, the display color is stunning and accurate for greater experience in gaming, watching videos, and more.


MSI, as an industry leading brand, is always improving, and will keep challenging itself in the design of gaming monitors. The unique SpectrumBar is not only a light bar that supports RGB lighting effects through Mystic light function but also features a new Glow Sync function that let the light bar automatically sync to the displayed content. Furthermore, MSI's exclusive patent allows the light bar to serve as an OLED care status indicator, showcasing the pixel/panel refresh progress to users intuitively. This feature prevents customers from accidentally shutting down the monitor before the entire process is completed.

MSI Gaming Intelligence and OLED Care function are the best examples of showing strong integration between hardware and software. Thanks to AI you will always be one step ahead of your opponents and reduce OLED burn in risks.

The MEG 342C QD-OLED also offered plenty of I/O ports to gamers who like to use KVM to control multiple devices through built-in USB hubs and charge smart devices with USB Type-C ports (Power Delivery up to 65W) and 4 USB 3.2 Gen 1 Type-A ports. It is equipped with 2 HDMI™ Port support 3440 x 1440 @175Hz as specified in HDMI™ 2.1 and is compatible with the latest gen of console devices.
