I'm considering the Optoma HD39HDR. To get the image position I want, I have to tilt the projector at 8.27 degrees and I will get keystone distortion of 5.56%. I have no idea if that's noticeable or not. Doesn't seem like a high number.
Should I be looking at units with optical vertical shift instead and not just digital keystone adjustment?
