Huh. Yeah, that is interesting. Like I said up-thread, I'm really curious about what that "Watchdog" item is under Other Options. I turned it off just to see what it would do, but haven't noticed anything yet. I'm also wondering what that PEQ submenu is all about.[/QUOTE]
I have turned off the "Watchdog" too, somehow it gives me comfort with it turned off...
I tend to agree with you on the light border. Light bouncing off the screen is definitely a contributing factor. Also the projected image size is almost bigger than my field of vision so unless I intentionally turn my eyes at the light border, it won't affect normal viewing.
The best news for me recently is the installation of the YouTube app Smart YouTube, which allows account login (hence channel subscription) and 4K resolution, and no longer need to rely on my buggy bluray player to stream YouTube.
