First time post :-)

I am a noob, but came across a problem straight away.

The image looks like this:

http://i301.photobucket.com/albums/nn47/gibbs131/screen.jpg

This is first day stuff so I presume can be adjusted like a monitor.

I could flip, rotate, side to side, vertically etc move it but not manipulate the right side of the screen. I won it on ebay and hope this is an easy fix. The lamp does need changing soon, just in case that is relevant.

That is usually the result of a projector that is not mounted square to the screen. Check your mounting. When it is correct, the image will either be square or BOTH sides will be angled in the same, which can then be corrected with Keystone adjustment.

The lens should be in line with the vertical center of the screen and the projector front exactly parallel with the screen. Any deviation will result in an off-kilter image that is difficult, if not impossible, to correct.

And the lamp will NOT cause ANY problem other than reduced brightness/contrast and perhaps a slight OVERALL color shift as it ages. ANY anomalies in the image will be the fault of some other part of the projector, NEVER the lamp.

your going to probably notice its never dead on balls perfect, in that it may overhang a tad in a corner and thats normal....if its like under 1/4 inch consider it good enough....thats what the masking border is for to hide this.
