Is the problem that the text can't render fast enough, or that you can't make the timer fire frequently enough? If the first - could you pre-render the text into an image (or a series of images, eg one per line, to swap in and out of a group) and scroll that? If the problem is that the timer doesn't fire enough - ie, I guess, that although you ask it to call you back in 1-millisecond, more time than that has actually elapsed before it does - does "the idleRate" effect this? Failing that, can you run your own tight loop, polling "the milliseconds" until it changes? (I'm guessing you don't really need to scroll at faster than 1000 pixels/second.)

Re: teleprompter application- reverse text, smooth scrolling?
no, no Flipping the WHOLE SCREEN at the MONITOR is the answer... electronically in real time. I'm sure there are flat panel manufacturers that make screens do that - very simple these daysthere might even be something in the OS that could do that. at the cheesiest - one I suppose could write fast XCMDs to rewrite the screen bitmap continuously backwards in real time but... you should stay with Standard display methods and find the right display. Remember the OPERATOR has to be able to read another, normal screen. This is better handled with a monitor card in the PC that can output NTSC video, as opposed to VGA. May I suggest you look into monitors /screens designed for the SUV 'TV in the back, shut up Kids' market - many have a reversing feature (for backing up the car in lieu of rear visibility) - and some come in sizes up to 12 to 15", and they're designed to run on batteries. These use 1V peak to peak video (in other words, standard composite video) instead of VGA to move the images around. VGA (and other computer formats) have higher resolution, but are harder to split, and since the characters have to be pretty big, the loss in resolution should be ok. And since the output would be standard video, it's easy to split and use anywhere with any NTSC monitor.
