connected how.
non vga is digital. signals, not analog.
and all scaling is fully automatic, inside the monitor (not adjustable)
both the card video and the monitor both must allow 720p
the data sheet on this monitor is clear.
I paste it now to you. (please note what is missing !)
640x480@60/72/75Hz,
800x600@56/60/72/75Hz,
1024x768@60/70/75Hz,
1280x1024@60/75Hz,
1440x900@60Hz,
1680x1050@60Hz,
1920x1080@60Hz
1920x1080x60Hz max and recommended.
no monitor does all resolutions and for sure not all refresh rates !
and the more it does the more it costs ,. you pay for that when new.
all that matters is the data sheet, read it and set the PC as you must or buy better GPU card, gaming needs a real PC desktop so that any card on earth can fit and work and do you you want
no PC told at all. why?

NO PC told no GPU card told
answers super hard to tell
nor what video cable ports used. my wild guess DVI
the first letter in DVI is what?, digital.
DVI is automatically scaled in the monitor completely unlike
vga is and VGA has fine tuning of HOR.and vert, scaling by hand.
you own the wrong monitor.
