i have p10 panels 4x3 and a 20str x 75pix ink 1003 , works well from 50-100 feet away, text and effcts are fine , gifs and video work but a little blocky.
if doing again would look at 60 led /m to increase the resolution and to move strings closer together (currently 30mm or 1.2 inches apart.
Hope this helps a little
