Yeah, i understand the whole "living with it".Im more frustrated and annoyed that I spent good money on this projector and am having this issue. I guess I will have to give Sony a call on Tuesday
Don't sweat it, you've got to just roll with it! And by that I don't mean what you think I mean...
I concur with Vlubbers and Fat Dave that this is most likely a positioning issue that can be solved. I had the same problem with my brand new PT-AE8000U, which is a much less expensive projector, and it drove me nuts for a while, until I figured it out.
In my explanation I'm going to use the aircraft flight terminology of yaw, pitch, and roll because that will make it easier. If you're not familiar, check out the Wikipedia page
The root of your problem I believe is that your projector is rolled, or banked, to the right (as you face the screen). Meaning the picture is spun a few degrees clockwise. Now you might be thinking, no, that's not the problem, because if it were, wouldn't the upper left hand corner poke up, and wouldn't the upper edge slope down left to right just like the lower edge? Well yes, you'd be right assuming that roll were the only issue. However, my bet is that you're also yawed to the right, meaning your projector is pointed rightwards a little bit, generating a horizontal keystone effect.
Now here's the kicker. If you geometrically combine image rotation plus horizontal keystone, you can end up with an image that appears level on the top edge but sloped on the bottom edge, with no appreciable distortions in the left and right edges, which is exactly what your photograph shows.
In order to correct this, you need to straighten up and fly right.
That means first rolling to the left. You do that by tilting the right side of your projector up a bit. Tilt it up until the right side of the image pokes up above the upper right corner of the screen by an equal amount to how much it pokes below the bottom right corner. What you should end up with is a sideways trapezoid where the left side of the image is shorter than the right side. Then, yaw your projector to the left, which will shrink the right-hand side of the picture relative to the left-hand side. Do this until the picture is square, lens shift it back into the center of your screen (a move that conventional aircraft cannot make!), and...voila, problem solved!
In my case, my projector is table mounted, so this meant extending the right adjustable foot to tilt up the right side, and then turning the projector to the left. I had to do this because my floor slopes down to the right ever so slightly.
The non-intuitive part here, which stymied me for the longest time, is that I was only thinking about, and making adjustments to, yaw and pitch. But that alone can't fix this. You have to roll as well. My guess as to how you got into this mess is that you started with a rightward roll but didn't realize it. You tried to correct it by yawing right in order to level off the top edge of the screen, but in so doing turned a one-axis error into a two-axis error, which behaves a lot less intuitively, and is quite confusing. I did the same thing.
I hope this works for you!
