Been super busy with work, family stuff. Anyway, I finally caught Covid, which has given me enough time screw around with my Sony 295 ES (1500 lumens) that I temporarily set up in my office while I remodel my living room.
I saw a video on YouTube about using a lux meter to measure projector brightness. He was using a JVC and he was getting 340 Lux on high. I forget the size of his screen.
The Lux meter, I got off Amazon was cheap. Like 30 bucks.
So after four hours of researching, tweaking and testing, I'm very confused.
Baseline, stock settings, D65, 50 every setting, 8bit computer, high lamp give me around 350ish Lux on a 77 inch image from about 8 feet.
Boosting RGB gain in the secret menu, high lamp, 60 contrast, my normal settings, gives me 550ish Lux.
Turning off Enhanced HDMI, limiting the bandwidth, and setting dynamic range to limited rather than full, gave me almost 800 Lux. It was quite bright. And it looked pretty good. My only theory on why this brightens the image is that running the projector in 1080 opens up the lcos color filters more, allowing more light through, but I'm just guessing.
Am I ruining the bulb by juicing the settings? Or is high bulb, just high bulb?
In some forum post somewhere there was a conversion formula for Lux to lumens. And I came up with 3700ish lumens, which makes no sense to me. I'm probably misapplying these measurements.
I'm more confused than when I started.
