    Your PJ isn't "aligned" correctly with the screen.

    Should be along the centre line (give or take) with the screen. Have a look at your manual for specific positioning details.

    Other possible cause is you've changed the keystone in your PJ menu.

    Is the image bigger at the top than the bottom, or vice versa?

    If say the left of the pj is a little closer than the right, the left will appear smaller - and trapezoid.

    You will find rotating the pj slightly to the right will straighten things up, but the image is off to the right aond off the screen - you have to physically move the pj to the left a little to line the image up with the screen.

    The same principal applies should the trapezoid be bigger at the other side. If it's bigger top or bottom, then you have to swivel the pj up or down to get the sides straight, then move the pj up or down to alighn the image.

    I mounted my screen first due to the constraints of the room, but you idealy want it so that eye height is approx one third from the bottom of the screen when seated.

    Then position the pj accordingly.

    You can buy ceiling mounts, or you can make your own. Some have used modified tv mounts (like those in Argos or Ikea), and others have used pipe fittings and mdf. I used a speaker bracket and mdg to fit mine, though it isn't as versatile as a proper one:
