I had an unusual issue occur last nite while watching Aquaman movie (ie UHD 4k disc with HDR). After the movie started, I noticed the screen was very dark during some of the early underwater scenes. In fact, the screen went dark on some occasions. I did a quick menu check to see if frame by frame HDR was on and as the "menu" came on, the entire screen brightened a lot where I could see the movie. Since it was on, I hit the menu button and as the "menu" disappeared, the screen got dark again. I then went to aperture setting and I was using Auto-2. I moved to auto 1 and it got better but was still very dark. I then turned it off and the scene lighted up a lot. I then changed to my Directv input which automatically goes to my USER1 picture mode which I recently calibrated for SDR and typical 1080 input. IT was very dark. I could lighten up by adjusting the aperture or contrast, but the picture was very dark for any applicable setting. I turned the projector off and then back on and everything returned to normal (as far as brightness/contrast at my standard aperture and contrast settings). I am assuming somehow the aperature was being driven by the auto 2 or auto 1 settings but I was surprised that switching to USER1 or any other picture mode setting did not correct issue.
Has anyone else had this issue with using AUTO 2 or AUTO1 versus manual?
