2560x1440 on UHD Graphics 630 Dell 7770 A10

I have a new Dell Optiplex 7770 A10 27" running UHD Graphics 630.  I need to run a screen resolution of at least 2560x1440 for development purposes... it doesn't appear on any of the selection lists.  Can you help me to achieve said resolution?  System details attached.

Are you connecting to HDMI or DisplayPort?

Are you connecting at 60Hz or are you attempting to use 120Hz/144Hz? If so, try at 60Hz.

Hi Scott,

Thanks for responding... the machine is an all-in-one so I am not aware of the underlying 'plumbing'.  I had hoped there would be some really cool driver update as the whole setup is relatively new and a fairly high spec.  I'll give 60Hz a go...
