Yeah my bad on that one. It would be nice if it had freesync, for me I only really care about the refresh rate though. Unfortunately I couldn't find many reviews on it.Why is your attempt at a link embedded in a broken media tag? Add it as a plain link, it's much easier.
From looking it up on ebay, the monitor looks pretty decent, though of course it's impossible to know if the limited on-paper specs provided have any bearing on reality. No way of knowing panel quality or if the controller is halfway decent. As for 120Hz, it has a USB-C input, so it has DisplayPort (alt mode). If the HDMI ports are 2.0 that can also handle 1440p120. A shame it doesn't have FreeSync, though, if it did I'd be very interested.
