The final step to setting up your projector for home theater viewing is to focus and optimize your image. The first thing you need to do is set the default aspect ration. This is the length and width ratio that the image will appear as. Typically, for home theaters 16:9 is the optimal aspect ratio. Focusing is next.
The best home theater projector is the Optoma UHD50. This projector hits a sweet spot, by combining 4K resolution, excellent color accuracy, and very high brightness, at a price that no TV can hope to match.
