Wow there is some flamming going on here. Let's all take a step back and look at this logically. Yes it is possible for a 1440p monitor to run 72hz(even 120hz actually). Yes there has only been some that that can actually run an overclocking refresh without frameskipping. Yes movies look better when you set a refresh that is a multiple of 24 since you remove judder and/or pulldown.
If we want to know if this monitor can possibly run higher than 60hz for sure then someone that has the monitor needs to test it and post there results. A popular tool for testing is the refresh rate multitool(flashing black and white bars). If you run this then it is going to be VERY obvious if it is frame skipping. 1440p at 72hz does pass the pixel clock limit on the DVI cable so a pixel patch will need to be used to conduct a valid test.
The smoother look on movies when having a multiple of 24 is perceptive. Only people who have a good eye for judder are going to see. Heck a lot of new monitors and players can just about play 24fps content on a 60hz screen perfectly. The FACT is that it does smoothen the playback it is a matter of mathematics there is no need to take anyone's word.
I know for a fact as well that some of these monitors can be overclocked without frame skipping. mainly because i am doing it and have ran the tests myself. If you want more definitive evidence and sample size take a look at the catleap and Qnix forums, or better yet have a nice chat with ToastyX.
Hopefully this helps you guys (lets take it down a notch
