It seems like you're already aware of the intermittent flickering while on low mode given you turned to high and it persisted, I've had it occur rarely while in low mode (which I am most of the time), but mine's always been resolved by turning it to high for a few seconds.
I am rather embarrassed to say that the issue was actually not even the projector at all. I came home yesterday after work and was prepared to tear the thing apart off the ceiling, but decided I'd turn it on again just for fun to confirm it was still flickering, and it wasn't flickering! I was baffled by it, and proceeded to enjoy my evening of some gaming. At the end of the night, I decided to flip to the cable source to catch the end of the World Series game 6, and the flickering was there again! I became really worried as I'd never seen this flickering before and assumed again the bulb was reacting strangely, perhaps to the change in the settings to the preset "TV" mode? Turns out, the HDMI cord going into the Xbox One was ever so slightly loose which was causing that intermittent signal that looked very similar to what I would imagine a dying bulb would look like.
Extremely relieved! Long story short, thank you for the quick help and I hope this bulb lasts another 1000+ hours!
Also, are there any recommended settings for the brightness/RC/color etc. listed by a forum user that people generally use to maximize bulb life while also maintaining a great-looking picture? Do people generally use the presets provided instead of doing some custom settings? Since I was worried about it, I took a look at the settings for "GAME" last night and realized it sets it to HIGH lamp which is overkill and I'd prefer to keep it at Low setting to preserve the life of the bulb.
