Looking at the design of the Cooler Master GM34-CWQ ARGB, at first glance it looks almost identical to the original GMC4-CW. Certainly from the front you would be hard pressed to tell them apart, with the inset bezels and curved 21:9 panel.
There are some slight aesthetic differences on the back of the screen though, with the GM34-CWQ adopting a more visually interesting design, with a couple of large glossy accents thrown in for good measure. There's no lighting on the back of the display though, whereas the GM34-CW offered two purple LED strips.
Cooler Master is still using a metal stand, as we saw with the GM32-FQ, and it offers a decent selection of ergonomic adjustments. There's up to 80mm of height adjust, 15 degrees of swivel in both directions, as well as tilt from -5 to 15 degrees. There's no pivot functionality, but that is less practical for an ultrawide monitor.
This is mostly fine, however I did find myself wanting a bit more in the way of height adjustment. Up to 80mm is just about acceptable for my uses, but the screen did sit just touch lower than I would have liked, and if you on the taller side, this may be something to consider. The good news is that VESA 100 mounting solutions are supported, so you can easily swap in your own monitor arm or wall mount.
The base of the stand is where we find the ARGB lighting elements, with an LED strip that runs around the inside of the hexagonal base.
On the back of the monitor, in the lower right corner, we find a small joystick used to control the OSD.
Lastly, as for connectivity, we find two HDMI 2.0 ports, one DisplayPort 1.4, and a USB-C port that can supply 65W power delivery. The USB Type-B upstream connector feeds two USB Type-A ports which are positioned on the left edge of the display.
A pair of 5W also come built in which offer a good amount of volume and a surprising amount of bass, though they are no replacement for a gaming headset or proper speakers.
