Ok so i have a Epson EH-Tw450. in my current house the walls are white / slightly beige and i project direct to the wall, all have been fine for a year but now moving to new house that has a slightly dark green(ish)/ wall. So im thinking on getting a screen. my old projected setup was as below, but the new size will be slightly smaller and less ambient light (ish) will still be used day time and night time. taken with iphone so excuse quality folks... and night time whats recommended for my projector and situation..?
