trouble with xorg on an external monitor

I am run Arch on a ThinkPad W520. This has the Optimus chip, but I have the switch in the bios turned to only use the discrete card (I don't really care about power-savings). When I use an external monitor it automatically sets the external to 1366x768 (same as the built-in display) I have configured xorg to display the second monitor, but I'm new to manually configuring xorg.  The monitors come up and the built-in is the correct resolution and the external is not. It is also kinda flashing and distorted. Running xrandr to change the mode of the second one says it can't find the mode. Below is my xorg.conf file. Can anyone give me some help on getting this set up.
