The HKC 27U240B combines Samsung’s fourth-generation QD-OLED panel with a 27-inch 4K display, a 240Hz refresh rate, DisplayPort 2.1, and USB-C with 90W Power Delivery. JD lists the monitor at 5,499 yuan, while an introductory promotion reduces the price to 4,799 yuan, giving buyers a 700-yuan discount during the initial sales period.
The 27-inch panel features a native resolution of 3840 × 2160, a 240Hz refresh rate, and a 0.03ms GtG response time. The high refresh rate provides smoother gameplay in fast-moving titles, while the 4K resolution delivers sharp text and detailed images for work, entertainment, and content creation.
HKC comes with a native 10-bit QD-OLED panel covering 99% of the DCI-P3 color gamut and 100% of the sRGB color space. It is certified for VESA DisplayHDR True Black 400, allowing HDR content to display deeper blacks, stronger contrast, and improved shadow detail.
Connectivity is designed for both desktop PCs and laptops. The monitor features one DisplayPort 2.1 port, two HDMI 2.1 ports, one USB-C port with 90W Power Delivery, two USB 3.2 Type-A ports, and a 3.5mm audio jack. The USB-C connection supports video output, data transfer, and laptop charging through a single cable.

The monitor comes with an ergonomic stand supporting height adjustment, tilt, and swivel. It is compatible with 100 × 100 mm VESA mounts for monitor arms and wall installation. HKC has integrated RGB lighting into the rear panel for users who prefer ambient lighting behind the display.
DisplayPort 2.1 provides the bandwidth needed for modern graphics cards, while the two HDMI 2.1 ports allow connections to current-generation gaming consoles and other compatible devices. The 90W USB-C Power Delivery port makes it easier to connect compatible laptops without carrying a separate charger.

The combination of a 4K OLED panel and a 240Hz refresh rate makes the 27U240B suitable for different types of workloads. Gamers benefit from the fast refresh rate and response time, while photographers, video editors, and designers can take advantage of the wide color coverage and 10-bit panel for color-sensitive work.
