CRT Terminal

Here's a monitor design I did today as a wrap for a kinetic type video I'm reworking. I like the overall direction of it, but I'll probably change some aspects of it before the final version. One thing I'm having issues with is the banding that's occurring on the screen, and when this is at full 720 resolution it's fairly noticeable. So if anyone knows how to handle large-scale gradients the help would be appreciated.
