useless keystone
Is it useful to use keystone correction????? I bought this one from the recommendation of youtube that say it has good qualities and price, having keystone function... I put it on the top of closet that is little bit high, so i tried to use keystone correction. But I couldn't get it to focus if i focus the top of screen then bottom is burry and vise versa. And if i give more angle over 10 degree i cannot focus all screen from 2.8m distance in spite of having keystone function of 20 degree
