xrandr screen fitting issues

[dakoellis]

not really sure how to search for this one. I've been using a couple of simple xrandr scripts to change the screen size based on who logs in. I have 3 screens and I need to turn one off and have the other two on. this is the one I had been using (and working well):

#!/bin/bash
	xrandr --output DVI-0 --off
	xrandr --output HDMI-0 --mode 1280x720 --pos 0x0
	xrandr --output DisplayPort-0 --mode 1280x720 --pos 0x0

now, I want to use the DVI instead of the DisplayPort monitor, so I changed it to this:

#!/bin/bash
	xrandr --output DisplayPort-0 --off
	xrandr --output HDMI-0 --mode 1280x720 --pos 0x0
	xrandr --output DVI-0 --mode 1280x720 --pos 0x0

The weird part to me is that in the first one, the monitors both switch to the correct resolution and display everything correctly, but in the second one, the DVI monitor displays everything correctly, but the HDMI monitor now is zoomed in and only showing the top-left corner and about two-thirds of the screen. Needless to say, I would like the entire screen to be shown on both screens. Lastly, here is the output of xrandr:

   720x400        70.1

I know that 1280x720 is not available for the DVI monitor, but I do need the monitors to be the same resolution (and would really hate it if they were 4:3 )

thanks in advance for any help that's out there with either the cause or the solution
