In this video, we compare a Fresnel screen and a CLR/ALR screen to help you understand which option performs better with ultra short throw (UST) projectors.Both screen types are popular choices for UST setups, but they behave very differently when it comes to brightness, contrast, ambient light rejection, viewing angles, and overall performance. Using real-world observations and side-by-side comparisons, I explain the strengths and weaknesses of each technology, without marketing hype, just practical knowledge.
