[SOLVED] Do GT 1030 GPUs supprot ultrawide monitors?

Solution
It supports up to 7680x4320@60 Hz.
3440 x 1440 is not a problem.
It would also depend on the physical interface cable. The HDMI output can't drive 7680x4320@60 Hz. Display port could, theoretically. As long as your monitor is HDMI or displayport and you use a quality cable, you should be OK.
