I have a G-Sync Ultimate and I don't have that problem. You can not, however, operate the scaler AND remove the black bands at the same time. It's an either or situation. I mean I don't know what I am talking about but it seems to me that if you have already used the scalar to enlarge the image from a preset scaler resolution option then you can hardly do it again to get rid of the black bands?? I don't know. I mean it doesn't make a lot of sense to me because surely if you have black bands then you haven't selected a NIS resolution, so the driver should be able to work things out, but apparently not. Either that, or I am just flat out wrong with my logic!! But certainly, I can not run both NIS and get rid of the black lines, the Control Panel will just not allow both to be configured at the same time.
