Need to use high-definition movies to enjoy. I checked the instructions, it is 4000 lumens, which is very bright, so I choose to try it in the daytime. I closed the curtain at 10 in the morning, and the screen is still bright, The machine sets at 16: 9, in the menu,The number of languages surprised me. It is not very noisy. I think it is acceptable. The only thing to note is that it is a little hot to the touch. and do not put paper around the machine. This machine is fully sufficient for family use. It's a great choice at this price.
