I have just bought the Neopix 230 and having issues getting a rectangular picture when the projector is on an angle to the wall.
The auto keystone doesn’t work, and the image is focused and sharp on the left, and blurry to the right. I’ll use the manual key stone to get it best I can to a rectangle shape, but it’s still blurry on the right side. I swap the projector to the other side of the room, same issue, but now left side image is sharp and right side is blurry. Front on to the wall, the whole image is sharp, so the issue is when it’s angled to the wall. This is pretty frustrating as this was the whole selling point of this device. I’ve tried resetting to default settings, starting with the projector at level then moving it, the surface it’s on is straight as well. I can’t see any guides or trouble shooting that relates to this, and particularly the neo pix 230. Any tips would be appreciated or I’ll have to return this. Even a guide on using the 4 corners would be nice but can’t see anything anywhere
