My Panasonic AE8000U still looks great and bright even with the 138 inch wide image. But, moving to a smaller home in November so the new smaller HTR will only give me about 116 inches wide with the AE8000U. I'll see if it bothers me. The BenQ HT3550 can do 138 inch wide in the same room but not as bright as the AE8000U. All other 4K projectors in the same price range seem to outperform the HT3550 but I love that large image.
