The last day or so I scrapped my current projector mounting locations for locations 2 foot closer to the screen. I was losing too much pixel density with the previous location and the screen door effect was too extreme to my liking. If I had to explain it, it was behaving like a 800x600 projector, not a 1280x800 in pixel density. The new locations are significantly better imho. I'm minimizing my pixel loss of projection splashing outside the screen area to minimums. Right now the projectors are on temporary DJ stands. Now that I know where they need to be fix mounted though I'll refabricate the back frame to match the new mounting points. No new materials are needed. I just need to cut a few of the pipe lengths shorter.
On a separate note, the more I use the current projectors the more I'm resigned in April to buying new bulbs. The uneven bulb burn in and the way the older bulb is flickering is problematic. I had a good run on those bulbs so I chalk it up to time to replace the bulb consumables with replacements. I figure that'll be $150 x 2, so that'll hit me a bit hard, but considering that is 2.5 years of use not bad I suppose. Projector bulbs are consumables. We need to treat them like that and always put aside about $15-20 a month in a bulb fund -- a bit of advice I always give out but haven't heeded personally. I'll keep on using the current bulbs till April. Right now it's only a cosmetic annoyance with white balance. I want both projectors to have uniform bulb use when I show off the screen at a convention in May though.
