Vankyo Leisure 470R Viva Projector

Brand Response from Vankyo Team We’re sorry the product didn’t meet your expectations. We would like to clarify that the projector does have a native resolution of 720p, so this is an accurate specification of the product. As for brightness, the projector is designed to perform best in darker or light-controlled environments. For the best viewing experience, we recommend using it in a dim or dark room and minimizing ambient light. The auto keystone correction currently supports vertical auto keystone correction only, so its adjustment range is relatively limited. If the automatic correction does not provide the desired result, we recommend using the manual four-point keystone correction to fine-tune the image. For the best overall image quality and focus uniformity, we recommend positioning the projector approximately 2 meters from the screen and projecting an 80-inch image. Larger projection sizes or greater projection distances may affect focus uniformity, particularly toward the corners. Your product is covered by a 1-year warranty, and please feel free to contact our customer service team for further support. Please reach out to us via support@ivankyo.com. We are more than happy to assist you further.
