My W1070 to HT2550 move and mount migration adventure continues. At a stopping point and could use some suggestions.
Where we left off: My I-Joists in the ceiling run back to front which limits my ability to exactly center the mount horizontally. Additionally, we determined my 4.25 inch offset called for a very close to ceiling mount, so specialty mounts with low profile ability were needed.
Here's where I am today.
- My electrician cut in a spot for a new outlet so we're good there (you'll see it in the photos). We were then able to confirm we were clear of the water and power lines back there, and safe to drill up into the ceiling.
- Since I purchased this mount per recommendation: https://www.amazon.com/d/Projector-M...ent/B072F4RGB4
, I decided to make a go with this one before purchasing something else.
- Electrician was able to confirm location of the i-joist to the left (looking towards back of room from front) of the new power outlet hole. Two of the 3 holes in the mount-it plate are now going into that joist. I will be using a Hilti toggler for the 3rd hole.
- Since the i-beam is left of center of the room by close to 2 inches, and the Benq lens is also to the left, I determined I would not be able to even close to center mount this plate on the projector, after doing some math, realized I would need to not only use 1 inch offsets and longer M4 screws to move this ULTRA close to the ceiling mount down a bit more, I would also need to place the mount off the edge of the projector to center it up.
And now, photos and questions for help.
- Once the projector is locked into the mount, there's no way to make adjustments to it unless I leave the 3 screws into the ceiling plate joint loose, but once the projector is up there, it's impossible to get at them to tighten them. Am I missing something obvious here?
- Am I just asking for trouble in the way I used the rails to hit the 3 mount holes and still have the lens be centered in the room? No lens shift projectors are the worst.
- Given the situation and inflexibility of my room, should I be giving up on this mount? Something just doesn't look right about the way it's done
- I'm noticing some blur on the grid in the lower left corner of the screen in the test pattern, should I be worried my refurb needs to get exchanged?
If you made it this far, thanks -- Please take a peek at the photos and any advice you give will be humbly appreciated. Oh, in one of the photos I used blue tape on the ceiling to mark the two back-to-front i-beam locations, and left the yellow level showing the exact center
of the room. I also attempted to place the Benq on a stool at the exact spot it needs to be (left to right, not at that height) to better illustrate the issue.
Thoughts? Thank you all so so much.
