Daisy Chain 4 Monitors

I have a Dell Latitude E6530 (purchased in 2012) which does NOT have a DisplayPort 1.2. If I get a Dell E-Port Replicator Docking Station (Dell Part # 331-6307), which does have a DisplayPort 1.2, will I be able to Daisy Chain 4 monitors assuming that the monitors have both a DisplayPort In and a DisplayPort Out? Or to ask the question another way, if I have a docking station with DisplayPort 1.2, do I also need DisplayPort 1.2 on my laptop in order to be able to Daisy Chain monitors with MST?  If I can daisy chain 4 monitors with this configuration, will it drive 1920x1080 on all 4 monitors?
