Keystone correction

Does anyone can help me with the  boarders that are visible in the ZTE spro 2, after I did a keystone correction? The original projected shape is still visible. see atachment. I always have a border that is visible (even without keystone correction) that I can't seems to get rid off. It might be normal, but it is realy anoying and gives a false immage of display size.

    The border is necessary for keystone corrections, in this way the image shape can be adapted without physically changing anything in the device.

    This means that if you project under an angle you do not fully use all pixels in the beamer and effectively lower your resolution slightly.

    This is the case for almost all, if not all projectors.

    The border when no keystone correction is applied is probably a bleed leakage on the edge of the display, you cannot enlarge the picture to this area and probably not remove it as well.

    Can someone who owns a SPRO2 confirm that this is always the case, if not you could contact ZTE about your specific unit.

    Do you think that this is the solution ​?
