Hybrid multi monitor setting - screens overlapping each other

I have two monitors, and a TV. Monitors on the discrete graph card, TV is on the integrated Intel GPU.
I managed to use all three simultaneosly, but something is wrong with the configuration...

The layout is: monitor1 (1280x1024) - monitor2(1280x1024) - TV (1920x1080).
The two monitors appear as one 2560x1024 desktop in KDE, the TV is a separate desktop.
If the mouse is on monitor1, and I drag it to right, it reaches monitor2, and after that it should appear in the left side of the TV, but instead it appears in the 2/3 of it (probably at 1281st pixel). After that, the mouse can use the full area of the TV. If I drag it back to the left, it fully skip monitor2 and appears at the right side of monitor1.
From that I suspect that somehow the area of monitor2 overlaps the top left 1280 by 1024 pixels of the TV.

I think the problem is somewhere in xorg.conf, but I don't know what...
