Screen or Paint???

[MonkeyShines]

Hello,

I’ve bought a Vanyko V600

I didn’t want expensive or high end and it has some good reviews.

I find myself stuck in deciding between getting a screen or using projector paint.

My accord ration is temporary but I will be here at least until until Christmas and don’t want to lug a screen around when I go but I would do it happily if if in the meantime I got more enjoyment from a movie on the screen than on the paint

Or considering the brand and model of the projector is there no difference between paint and screen?

Would projector paint even be necessary ? Would ordinary grey house paint do?
