RE: hp prime flickering when scrolling

They are 2 flickers...

1) is HW flickering. This line that you sometime see that goes up/down through the screen.
This is a stroboscopic effect between the screen, your eye and whatever lighting is around. We have done everything we could to minimize it, and some people are more sensible to it than others, but there is not much we can do about it (screen refresh is set to 55hz to be different from the US 60hz and rest of the world 50hz main frequencies).

2) is SW flickering, this is the one that you see when you cause the screen to redraw as you interact with the device. This one is something that we can do something about (and have done in a lot of places). But not in the home screen.
Solving SW flickering takes extra work from us, and tends to slow things down (or make it look slower)...


Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP.
