BenQ TH575 vs BenQ X3100i

“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.”

“Hey, thanks for taking the time to reply. I did not mean to say that information is wrong, just showing another source for comparison ... apologies if I sounded rude, that was not my intention. I wonder whether the lower contrast in the x3100i is because of the brighter black floor. Also, looking at the curve on rtings, the contrast ratio is significantly lower on very dark scenes, and almost identical in more balanced scenes, so In practice I wonder how much of a difference that makes when watching movies. Do you think the choice should be based on amount light control and screen size? Another question, because I’m also kind of torn between these models: do you think the 4led source in the x models has big benefits compared to the single laser of the tk models (less artifacts / wider color gamut) or do you think the contrast would be the more decisive factor?”
