+8 pts“there are no great projectors at that price. thats the minimum decent projector. If you look you can find a benq th575 for your price on sale and its a solid projector. great projectors are north of $2k.”
r/projectors
ViewTop Criticism
+2 pts“Projectors are not designed to be used in broad daylight. You may have projectors with high brightness but ambient light will affect your blacks and it will ruin the contrast. I have tested the [BenQ TH575](https://www.laurentwillen.be/en/test-reviews/projectors-tests-reviews/benq-th575-projector-test-review-price/), it's a good projector in this price range but it doesn't have enough contrast to fight the ambiant light. The Samsung Freestyle is not a good option, it's too weak in brightness. So if you can accept poorer contrast, the BenQ is a good option.”
