Anything wider than 1920 can not be used with an ordinary DVI adapter, or converter from HDMI. It requires Dual-Link DVI, which has three additional data pairs in all the cables all the way through.
appropriate adapters from USB-C appear to be available from:star tech, club 3d, Ez quest , cable creation for around US$50 to US$100.
