You need to wonder if Cooler Master is slowly spinning out of control, with too many and often too expensive products. regardless, the will be entering the monitor market as well with a 30 and  35" 21:9 gaming monitor.

Both units offer a screen ratio of at 21:9 and are based on a VA panel. At 30-inches at 2560 x 1080  the GM219-30 is the 'smaller' model. It's a 200 Hz monitor. The GM219-35 is a 35" monitor has a higher resolution of 3440x1440 at 120 Hz. Obviously, both display offer support for adaptive sync and thus should work with AMD (FreeSync) and Nvidia (G-Sync) cards

Albeit the details are dim, both monitors should offer some level of HDR support. We know this because of a FreeSync 2 certificate, and revision 2 is HDR supported. Both screens are expected to have a response time of 1-millisecond albeit whether that is gray to gray or mprt speeds remains a big yellow question mark.

A small funny observation, you'll notice that the monitor stand is shaped after the Cooler Master logo. With a bit of luck the monitors should reach the market by late 2019 with prices at roughly 399 USD for the 30" model and 999 USD for the 35" version.
