Right image corner is higher

[Carljohan_Selke]

I tested this on the floor and used calibration
And it always set the right corner of the image little bit higher why is that ?

Remember someone els posted this issue somewhere here ?

Are you projecting on to a screen or wall?

[Carljohan_Selke]

can delete this topic i may have misscalculated and ppm maybe was slightly angled wrong

[GiacomoR]

Hi, I have the same issue. ppm flat on the floor and still projecting tilted despite calibration done…

[noname729]

same here, happening these few day, for mine, the right top corner is bending outward to the right.

@GiacomoR @noname729

Can u post an image of the projector and the projected screen?

[djupsjob]

Is it actually bending (ie. curved) or is the projection just not 100% straight? The reason I’m asking is that having it rest completely flat on a surface isn’t necessarily enough to achieve a straight picture. The projector is very sensitive when it comes to positioning and having it positioned at even a slight angle in relation to the surface that is being projected on can result in a picture that is not 100% straight. On the other hand, if the side of the picture is bent or warped, it might be something else.

[GiacomoR]

I think is really the straight the problem. Managed to took a picture projecting on a very close surface so when far the effet is more pronounced

The fact that the PPX is on a level surface and itself level also, doesn’t guarantee a good projection, it also has to be perfectly perpendicular to the screen.

@IvoGrijt

This happens to me sometimes as well, I find that I have to move it a bit in a turning motion to find the right angle to the wall, as what I think is parallel isn’t always actually parallel. The image displayed will tell you that right away, in this case in the upper right corner.

Edit: I made a quick drawing showing what you’re seeing. You should rotate the PPM around its vertical axis (imagine a pole going straight through the middle of the PPM from the top to the bottom of it) a bit to the left (as the distortion is at the right)

Also if you’re projecting on to a wall, check how flat the wall is, on 1 of my walls I get a lower right hand corner always at the exact spot, after checking with a straight edge I noticed there is a kink in that section of the wall not noticeable normally to the eye but enough to distort the straight line of the bottom of the projected image.
