DPI issue with multiple displays

Hi all,

I’ve got a 2x2 display setup using 1080p displays. Models BENQ GL2450 (x2), BENQ 2405 and BENQ BL2410. The DPI doesn’t seem to be correct (small rubbish looking text in Kicker and on some menu bars. Does anyone know how I can correct this? I’m using the NVIDIA proprietary driver. No settings related to monitor or display are set in xorg.conf. All assistance greatly appreciated!

Nvidia driver version 340.76
KDE v 4.14.9
xorg-x11-driver-video-7.6_1-14.1.3.x86_64
xorg-x11-server-7.6_1.16.1-19.1.x86_64

xorg log says:
