ASRock's 27-inch Tandem WOLED gaming monitor hits an impressive 720Hz for esports gamers

Q: What hardware is needed to actually run the TCO27QXB at 720Hz in esports games?

You would need a modern CPU and GPU capable of pushing esports games at 1280 x 720 with uncapped frame rates. The story does not name specific processors or graphics cards, only says current CPUs and GPUs can handle 720Hz at that resolution more easily than QHD 540Hz. It also points to competitive games like League of Legends and Counter-Strike 2 as the kind of titles this mode is aimed at.

Q: Does the TCO27QXB support 720Hz over DisplayPort, or is that mode limited by a specific input?

The story does not say that 720Hz works over DisplayPort specifically. It only says the TCO27QXB has two display modes, with 720Hz available at 1280 x 720, and notes USB Type-C with DisplayPort Alt Mode among its connectivity options. So this article supports the 720Hz mode, but not which exact input it is tied to.

Q: How does AMD FreeSync Premium Pro work with the TCO27QXB’s 540Hz and 720Hz display modes?

AMD FreeSync Premium Pro is listed as a supported feature on the TCO27QXB alongside its 0.03ms response time, but the story does not explain any mode-specific behavior. The monitor's two display modes are QHD at up to 540Hz and HD at up to 720Hz, and FreeSync Premium Pro is simply described as a feature that enhances gaming performance.

Q: Is the USB Type-C port with DisplayPort Alt Mode enough to use the TCO27QXB with a laptop for gaming?

It only says the TCO27QXB includes USB Type-C with DisplayPort Alt Mode as part of its connectivity. It does not say whether that connection alone is enough for laptop gaming, or what refresh rate or resolution a laptop would get over it.

The new ASRock TCO27QXB Gaming Monitor features a cutting-edge 27-inch Tandem WOLED panel that supports two display modes for esports gamers.

TL;DR: ASRock's TCO27QXB is a 27-inch Tandem WOLED esports monitor offering QHD (2560×1440) at up to 540Hz or HD (1280×720) at 720Hz, VESA DisplayHDR True Black 500, factory-calibrated 99% DCI-P3, 0.03ms GTG, AMD FreeSync Premium Pro, USB-C DP Alt Mode, and competitive-focused features.

ASRock has formally announced its new lineup of flagship Taichi gaming monitors, all featuring advanced OLED panels and focusing on image fidelity and performance. Perhaps the most notable model in the lineup is the competitive-gaming-focused ASRock TCO27QXB Gaming Monitor, with a 27-inch Tandem WOLED panel and two display modes: QHD (2560 x 1440) at up to 540Hz and HD (1280 x 720) at an impressive 720Hz.

Yes, the big caveat is that this blisteringly fast refresh rate isn't available at 1080p, but at 720p. This resolution is rare in the gaming monitor space, but because it's the pixel-accurate divisible resolution of 1440p, it's really the only option for a QHD display with dual display modes. Gaming at 720p will result in a less detailed or crisp image, but the 720Hz refresh rate will still deliver noticeably improved motion clarity.

On top of that, modern CPUs and GPUs can run games at 720Hz at this resolution more easily than at QHD 540Hz. This makes it a premium OLED display for esports and competitive gamers who play titles like League of Legends and Counter-Strike 2 with uncapped frame rates.

It also supports AMD FreeSync Premium Pro and a 0.03ms (GTG) response time, features that also enhance gaming performance. And like the rest of ASRock's new Taichi gaming monitor lineup, it features custom display modes and 'Gaming Assist' features, and versatile connectivity that includes USB Type-C with DisplayPort Alt Mode.
