Samsung has reportedly developed the world's first 27-inch OLED panel capable of a 500 Hz refresh rate at 2560x1440p resolution. The new panel utilizes Samsung's QD-OLED (Quantum Dot OLED) technology, which combines the color accuracy of Quantum Dots with the contrast and responsiveness of OLED displays. The panel is nearing the end of its development phase, and Samsung is reportedly in discussions with leading monitor manufacturers, aiming to introduce products featuring the panel to the market by mid-2025. This development adds to the growing competition in the gaming display market. For example, Chinese company Light Soul is preparing to release a 27-inch QD-OLED monitor with 4K resolution, a 240 Hz refresh rate, and a peak brightness of 1000 nits. Meanwhile, LG plans to launch a 45-inch monitor model featuring a 5120x2160 WOLED panel.

Across the industry, OLED is being transformed using various technologies, and every panel maker, including Samsung and LG, wants to stay ahead of the curve with high-refresh, high-color accuracy panels. The high-refresh-rate market is currently led by LG UltraGear 27GX790A-B and ASUS ROG Swift PG27AQDP 1440p monitors that max out at 480 Hz. While e-sports players might need the extra 20 Hz, regular users surely wouldn't notice the extra refresh. Nonetheless, it is interesting to see that OLED is getting lots of love in the coming year, and the constant development of it will not stop.
 
Looking forward to reviews of this monitor once released.
