They also require Sync on green, which can be selected if you download powerstrip. If you just select composite sync it wont work, you need both of these. The problem is that windows wont default to composite sync/sync on green so you must start the computer with a normal monitor, then select composite sync and sync on green from powerstrip then swap the monitors over for it to work.
