Color problems

Hi I was wondering about I problem I found when I was using DK2 with an Alienware laptop and UE4 demos.

These are from the rollercoaster demo:

This is a flying demo:

There is a constant curved thick border around the viewport.

So anyway this problem is visible on the headset and the laptop monitor.

    I got this reply:

    What you might be seeing is correction for the chromatic aberration caused by the Oculus optics. Basically, the lenses in the headmount affect the red/green/blue channels slightly differently. To correct for this in the headmount, you'd need to introduce an inverse aberration in the rendered image. See this thread on the Oculus forums:
