2 years of ViewSonic PX748 4k HDR Projector: Problems? (filmed with mobile phone). So we experience problems with the model ViewSonic PX748. In 2 years, at 4000 hours lamp usage, we had big chromatic aberrations, and flickering of the image in the ECO mode. Is not a bad projector, it has a good image quality for a lamp projector and a good solid build but at only 4000 hours usage the lamp lost a lot of lumens and the chromatic aberrations and the flickering were to much to handle!
ViewSonic accorded the warranty without any problems but it take 1,5 months to solve in warranty this problem. After this problems i advice users to get extended warranty or buy another brand.
