Absolutely, no need for high lamp at all. If you had Madvr you could get the same brightness as with Natural mode in low lamp for UHD movies.I have found the ideal settings for both 4K movies and HD movies and NONE of them have the lamp at the highest setting. I tried it at a high setting as I'd read that you need to do that for the first 100 hours to prevent lamp flicker but honestly it's way too loud to even enjoy a movie. If you get unlucky enough to get lamp flicker, is it such that you'd need to replace the bulb or would the flicker go away with a bit of time spent at the high output setting? Every time I fire up a movie I'm just blown away by the image this thing projects - I'm so thoroughly impressed by it!
