Hi,
I've recently bought a Korean 27" 2560x1440 display, and have been having trouble trying to get it to work with my laptop (Toshiba portege r830-13c so intel integrated graphics), connected using an HDMI to DVI-D cable (monitor only takes dvi-d).
Originally the laptop cannot find any compatible modes for the monitor (maybe an EDID problem?), but after supplying a 2560x1440 mode to xrandr:
xrandr --newmode "2560x1440_60.0" 311.83 2560 2744 3024 3488 1440 1441 1444 1490 -HSync +Vsync
xrandr --addmode HDMI1 2560x1440_60.0
The monitor displays the extended desktop, but it oddly seems to be replicating the second monitor's workspace tiled over the screen...

I have no idea what could be causing this, so any help or suggestions would do the world of good..
Thanks,
