luckymaaa6 years ago000Can you use it to make a short PPT presentation in the club? Does it really have to be pitch black in the room to see anything?

It should be quite dark, and I don't think the colour reproduction is that great. But it's enough for my needs. For your purpose, I would probably buy something more powerful.Show in original language (German)Comment
