ASRock has expanded beyond its existing display range with the Taichi family, its first flagship OLED gaming monitor lineup. The three 27-inch models target different priorities, from 4K image quality to extreme esports performance, with refresh rates reaching 720Hz and dual DisplayPort 2.1 UHBR20 connectivity.
Key takeaways
- Three 27-inch OLED monitors join ASRock’s Taichi lineup.
- The TCO27USA combines 4K resolution with a 240Hz refresh rate.
- The TCO27QXA offers QHD resolution at up to 500Hz.
- The dual-mode TCO27QXB reaches 540Hz at QHD or 720Hz at HD.
- All three models include HDMI 2.1, DisplayPort 2.1, USB-C, and ergonomic stands.
ASRock has not announced pricing or retail availability, although product pages for the displays are now live. That leaves the monitors’ market positioning unclear, particularly because high-end OLED panels and DisplayPort 2.1 connectivity typically command premium prices.
Three OLED designs for different gaming priorities
The Taichi TCO27USA is the image-quality-focused model. Its 27-inch 4K UHD Penta Tandem OLED panel runs at 240Hz and carries VESA DisplayHDR True Black 400 certification. ASRock lists a 0.03ms gray-to-gray response time, 99% DCI-P3 coverage, factory calibration, and Delta E below 2, making it suitable for both gaming and color-sensitive work.

For competitive players who want a higher frame-rate ceiling without giving up QHD resolution, the TCO27QXA uses a 27-inch QD-OLED panel with a 2560×1440 resolution and 500Hz refresh rate. It also offers VESA DisplayHDR True Black 500 certification, OLED contrast, and the same claimed 0.03ms response time.

The TCO27QXB targets extreme esports performance
The TCO27QXB is the most unusual model in the launch. Its 27-inch Tandem WOLED panel supports QHD at 540Hz, but switches to HD resolution to reach 720Hz. The dual-mode design lets users choose sharper visuals for regular gaming or the highest possible refresh rate for fast-paced competitive titles.

A 720Hz mode will require a system capable of rendering frames at exceptionally high rates, so it is aimed primarily at esports players and enthusiasts rather than typical single-player gaming setups. It nonetheless gives ASRock a notable specification for its first Taichi display generation.
Modern connectivity and practical features
Each monitor includes two HDMI 2.1 ports, two DisplayPort 2.1 ports with UHBR20 support, and USB-C with up to 65W Power Delivery. The dual UHBR20 configuration is particularly notable for users seeking high-bandwidth, uncompressed display connections at high resolution and refresh rates.
The lineup also includes AMD FreeSync support, a built-in KVM switch, low-blue-light technology, and adjustable stands with height, tilt, swivel, and pivot movement. Taichi rear lighting completes the flagship styling, while USB-C can function as a display connection or provide power to a compatible laptop.
Availability remains unconfirmed
ASRock has disclosed the core specifications but has not provided launch dates, regional availability, or pricing. Those details will determine whether the Taichi monitors compete directly with other premium OLED gaming displays or occupy a more specialized enthusiast segment.
