https://www.pcgamer.com/asus-is-releasing-a-27-inch-4k-144hz-hdr-monitor-with-g-sync-in-june-for-dollar2000/ > Asus and Acer are each planning to release a 27-inch 4K monitor with a fast 144Hz refresh rate (overclocked) and support for both HDR visuals and Nvidia's G-Sync technology—ROG Swift PG27UQ and Predator X27, respectively—and both are slated to arrive this summer. However, it looks like Asus is aiming to beat Acer to market ever-so-slightly by announcing availability in June. > Acer previously announced its monitor would arrive in July, though neither company has offered up a specific release date. So, it's not yet clear how much of a jump start Asus will have over what will be the only other monitor of its kind. That said, buyers with the requisite cash can already preorder the Predator X27.
