Chain = PS3 > Moome IFB-FULLHD v3 > G70.

(ceiling mount) Folding and distortion on the left side.
Moved image to the right as much as I can without cutting off the image.

No problem with lower resolutions.

Any way to solve this without resorting to a VP?

Thanks

Does the Moome have any porch adjusting capability?

If not reduce image size and shift off center. Similar to other PJs that shift the raster off center.

Moome doesn't. Need a VP

Weird, I just have a tiny bit of banding on the left couple of inches of screen on my G70. Definitely no raster-wrap.

I have a PS3 also, but I use the HD Fury for D/A. I guess the Fury must have a bit more porch in the signal than does the Moome.

The moome has image shift but I don't think that is going to help me.

Is there a way to expand raster and contract image?

The SIZE key is what controls raster size.

RGB SIZE is the active image.

You want to increase raster (SIZE) and try decreasing image size (RGB SIZE) to compensate.

The raster-wrap is the projector starting to draw the beginning of the scan line before the beam has returned to the beginning of the scan. This happens when the front- and back porch (horizontal blanking interval) gets too small. The Moome must have just enough smaller porch the the G70 won't handle it like the 1080p from my HD Fury.

What I always do on a G70 when I hit this problem is to apply blanking to the left and right sides to cover the bend in the image. After that, center the image in what's left of the usable raster space and move on with your setup. You will now have some overscan on the sides, but it's not a terrible amount. Increase the height of the image and apply blanking such that the overscan is equal on all four sides.

I will try that.
I did notice that it is not the image that is wrapping.
The image is full.
It is the raster itself that is wrapping and creating the line shown on the left of my first pic.

The tip worked for getting rid of the line and distortion
but this solution did not feel very satisfying.
Although, since I'm only loosing 1.25% of the image with the overscan, I suppose I don't have much too complain about.

I'm going to contact Moome and see if he has any suggestions.

Have you tested the new IFB-FULLHD v3 yet?

Thanks
