auto keystone vs. manual keystone vs. no keystone correction concerning Acer H5360
I have my Acer H5360 standing behind me 1.3 m above the floor. The bottom of my screen is about 80 cm above the floor. Due to that fact I have to project downwards. Since the Acer has no Lens shift I have to lift the rear portion of the PJ which I do with some cardboard.....and it works.
Someone here mentioned that the auto keystone works perfectly. I can't agree on this. While the auto keystone gets the job done it's not perfect on my screen which has 3.8m (121 inch) diagonal and is projected from 4.3 m (14 feet). Looking at the top right or left of the screen and then looking to the bottom right or left of the screen shows clearly that the auto keystone works not perfectly. While the projected image perfectly fits the top of my screen, there are 2cm missing on each side of the bottom. So the outer lines of the projected image are not perfectly straight.
Now I have 3 burning questions which I would really appreciate to be answered:
1. How is your Acer's H5360 auto keystone working. Did you notice too that it's not working "perfectly"?
2. I could easily fix that problem (which is really really minor) using the manual keystone correction. But no matter where I look everyone says not to use the manual keystone because it's producing artifacts and image distortion.
3. Generally what is the difference between the auto keystone correction and the manual keystone correction (apart from the obvious manual vs. auto)
Doesn't the criticism for manual keystone correction also apply for the auto keystone with the only difference that you don't do the correction by yourself?
