Dell has announced the availability of new G-series monitors in the US and Canada. They include 32-inch variants with "fast IPS" panels, one of which is 4K/UHD and the other QHD and USB type-C enabled. They both support AMD FreeSync Premium Pro and fast refresh rates, although only one of them features HDMI 2.1.
