So I bought 2 identical monitors so I could happily play games with higher FOV without it looking like I'm staring down a telescope. Regardless, that's not the point. One monitor is connected via a VGA cable. (Using DVI to VGA adapter) and the other a straight forward HDMI. The vga monitor works perfectly and sharp. The HDMI one doesn't display "fullscreen" it leaves big black boarders all round. If I lower res from 3840x1080 to 3200x900 it works as intended (thought not as sharp as I'd like. But in games it reverts back to 3840x1080 and is horrible. I've been using AMD's eye-finity stuff to get this far. If anyone can suggest something I'd be very grateful. Thanks

It sounds like your underscan/overscan settings, you can change it in ccc under your digitial display settings (do a quick google search as I'm responding from a mobile)

Edit: Setting in ccc is under " my digital flat panels" > " scaling options". Just move the slider around to see what you need for your monitor.

I have to change those settings every time I change display hardware.
i think your problem is the analog/digital mismatch... you might want to swap over to a DVI-D or minidisplay port or something other then VGA...

if that doesn't work... make sure your desktop is stretched, make sure the resolution for both in the windows setting is 1080p, then have the monitor with the funky display to auto adjust it's picture (there should be a button on the monitor called auto or something).

give those a try too.
