I just bought Dell Venue Pro 11 (7140). Unfortunately I've noticed that all over the screen there are stripes or rather squares, especially visible on white background (e.g. notepad).
My assumption is that those are artefacts of digitizer, but it should not be a case for high quality Dell's devices. I rather expect something like that on cheap tablets.
I would be appreciate for quick feedback if that is standard for Venue devices.
