ASRock is preparing to launch two new monitors in the Taichi series. The manufacturer is focusing on 27-inch OLED panels and two different directions: one model is aimed at esports players and the other at people looking for a combination of high resolution and very fast refresh rates. Sales in Japan are due to start on 30 October. Prices are 147,800 yen (about 700 GBP by a straight conversion) for the QHD 500 Hz model and 169,800 yen (about 800 GBP by a straight conversion) for the 4K 240 Hz variant.

500 Hz 2K or 240 Hz 4K

The first monitor is the ASRock Taichi TCO27QXA. It offers a 27-inch OLED panel, a resolution of 2560 × 1440 and a refresh rate of up to 500 Hz. The second model, TCO27USA, features 3840 × 2160 pixels and 240 Hz. In both cases the manufacturer declares a response time of 0.03 ms, 99% coverage of the DCI-P3 gamut, colour accuracy Delta E<2, and support for AMD FreeSync Premium Pro. In practice this means ASRock is targeting two segments at once. The QHD 500 Hz model appears aimed at competitive online gaming, while the 4K 240 Hz targets a more versatile premium gaming audience.

Rich connectivity and plenty of features

ASRock has equipped the new monitors with HDMI 2.1, DisplayPort 2.1, USB-C with up to 65 W power delivery and a KVM switch. The manufacturer also provides a fully adjustable stand: pivot, height adjustment, swivel and tilt. In the 4K TCO27USA model the VESA DisplayHDR True Black 400 certification has also been confirmed, along with two HDMI 2.1 ports and two DisplayPort 2.1 UHBR20 connectors.

So far this is a launch in Japan. ASRock notes for the TCO27USA model that the device may not be sold in all markets, so European availability remains to be confirmed.
