I have laptop with Intel HD 4600 (i7 4gen CPU) with 1080p screen. I want to connect my laptop to 1440p external screen by HDMI. By default my laptop see only 2048x1152 resolution.

I made xorg.conf file and modify using "Modeline" option in "Monitor" section and "Modes" option in "Screen" section. After that my laptop screen had 2560x1440 resolution (but of course didn't work, because laptop have only 1920x1080) but my external screen still have 2048x1152...

Any idea?
