Im having a problem getting the projector centred to the screen after ceiling mounting it. I mounted it in the distance range recommended by many calculators online including BenQ's and others. But the image just wont match up horizontally regardless of how much I zoom in or out... what gives? This is my first projector so I may have mounted it incorrectly but as I understand it the centre of the lens of needs to be exactly at the centre of the screen horizontally, yes? So for example I have a 92" 16:9 screen which is basically 80" wide. So if I mount the projector where the centre of the lens is at 40" horizontally lined up with the screen I should have a perfectly centred image horizontally, yes?

Issue is Im out by a lot at the moment horizontally (like 6-7") and I dont think I mounted it that incorrectly... Perhaps its a setting in the PJ or something? I have it at auto aspect ratio.

When I move the projector lens about 6" left of the centre of the screen the image then seems to be correctly displaying at-least horizontally.... does that seem right? I thought the idea was to have the centre of the lens exactly centre with the screen to get the image correct horizontally...

Any help is appreciated...

Still looking for a suggestion to my problem below if anyone can help, please...

Mmmm, that's strange. I demo'd a w1070 and the centre of the lens was in line with the centre of the screen - the top and bottom of the projected image were both totally straight i.e. no sign of horizontal keystone. It's a longshot, but maybe your screen isn't totally parallel to the projector??

If the wall you're measuring from isn't totally straight and/or the screen isn't totally parallel to the projector and/or your measurements aren't totally spot on then you may well see some horizontal keystoning (6 or 7" does seem extreme though). Hope this helps

How do you know you don't have keystone problems now? Have you checked? Rotate the projector until the image is where you want it, then check the image using some of the calibration features. If the image is stretched or skewed and you cannot compensate for it using the built in adjustments then you will have to reposition the projector. Typically yes, the projector will be in the center of the screen and perpendicular to it. How did you make sure you are in the exact center? Maybe your wall isn't straight and it threw your measurements off. Sometimes people just use a tape measure and more or less eyeball things and hope it's good enough.

Because of crooked walls you can't always depend on measuring the distance from one of the sidewalls both at the screen location and the projector location.

I keep my PC desktop running at 1080p 60 hz which is usually the "native"resolution for PC but whenever I play a movie, even a 3D movie, PowerDvd takes over and at most for a 3D movie I just have to click on that 3D icon and it takes care of the rest. It plays at 1080p 24fps. Once the movie is over, my desktop returns to the 1080p 60fps which is much better for mouse movement etc.

If you want to play a 3D video at 720p 60fps, then you would have to set your desktop to that first and then play the video in, say, stereoscopic player, but that is an advanced technique for 3D videos with fast motion, and would not be relevant to BlyRay playback.

If you use a different media player thanPowerDvd, then, we'll, I'm not sure. but for that one, you can keep your desktop to native mode, 1080p 60 and let it handle the switch to 24 fps for you.

Not bad for a projector recently released.

edit: the w1080st is on there as well for $100 more

So you would take half the screen width and square it, then take the distance to the screen and square it. Add that together and take the square root. In this case lets say my screen is 87" wide, so it would be [(87/2)^2+144^2]^.5=150.4"

That number should be the horizontal distance from your lens to the edge of the screen. If your screen is below this you would have to project up to where the edge would be.

If it were off a quarter inch or something I wouldnt be too worried, but if it was like an inch out there's something wrong.
