Thanks to LSIBERIAN, Jostenmeat, Mississippiman (AVSForum), and pb_maxxx (AVSForum).

To recap I picked up the Sanyo PLV-z60 (Thanks LSIBERIAN/Jostenmeat) for the bargain price of $659 shipped (now back to $850). MM and PB have a killer thread titled Silver Fire Mix. One of the nice things about the SF formulation is it helps make the most of low lumen projectors.

My setup is a 94" diagonal 16:9 screen with the projector throwing from 10 1/2 feet.

The SF mix:


Pulling two 12/2 lines plus RG6


Down through the ceiling:


Finish ceiling with HDMI pulled:


The other end:


Hung with care:


Primer going up (the projector looked only 'ok' on primer):

Continued...

Decided to paper and tape the wall out and roll 1 more primer coat (should have done this to start with:eek:):


After a few 'duster' coats and the first top coat (you can see the non-uniform surface, the paint was spraying fine with the Wagner but should have been thinner):


2nd coat (now the paint is thinned more) with more even coverage:


This is after the 3rd coat with two more 'duster' coats. Screen looks super uniform under normal room lighting.


Without calibrating the PLV-z60 and running in Dynamic mode I popped in Iron Man (DVD). OMG. Anyone that says they will just throw up some white paint doesn't know what they are missing.

I would have to say the colors were 'Plasma' like. Very rich, vibrant and they simply popped. Blacks were solid. I am completely stoked!

Some screen shots to come when I can perfect the process.

I thought you were using a mirror?:confused:
I did some more digging and there really wasn't a compelling reason to do the mirror. Even the guy that does a lot with the acrylic mirror let me know that it is not a make or break.

In the end I chose expediency and efficiency. With a kid on the way my window to get things done it shrinking (and fast).

It still looks KILLER.

Will do. I have to figure out the best settings with my camera and do a 'lights out' capture.

Please keep in mind that:

1: The PJ is not calibrated (currently using Dynamic Mode)
2: I know next to nothing on how to properly use a camera to take a picture of the projected screen







The camera is kind of 'washing' out the image. As an example with Iron Man the face is washed out, on screen you see the left side (screen right) of his face. The camera is simply doing something to the recorded image.

:cool:

i did a S-I-L-V-E-R on TWB. it looked FANTASTIC. gain was about 1.5.
it just wasn't big enough.

But what screen color/gain did they do this with? I am not sure if those numbers make sense with my gray screen.

Correct me if I am wrong but one calibration that is correct for a white 1.0 gain screen would be wrong on another (different screen)?
Good question, and yes, nothing replaces doing the cal yourself. Not only is there the gain of the screen (and other properties of the screen), but there is also the size of the screen, light control, even shift of PJ as well as throw of PJ. Of course, there's also unit to unit variation, and maybe even bulb variations. Finally, there is personal preference to calibration as well.

Will the final cal be close to the reviewer's? Very possible. Still, a couple of years ago perhaps the very best value in 1080p PJs (Epson 1080UB) also was said to have the greatest unit to unit variation by someone who sees a LOT of projectors, sells a lot, and calibrates a lot, for many years.

Personally, I would take it off dynamic, pronto. When the bulb is brand spanking new, it's almost naturally "dynamic" anyways, but new bulb + dynamic means some white crush like your getting on your last screen shot.

Lastly, I remarked that the blacks of Iron Man were very light, though I thought it was a fun movie. I think, with my very questionable memory and subjective experiences, the best black/shadow detail I saw was in an old French black and white movie, The 400 Blows. I even asked elsewhere if BW movies just made it look that way, and a video pro (critic/contributor/curator) explained that it was because Criterion did not artificially boost contrast levels here, which allowed blacks to remain uncrushed. Wow, that was a nice tangent.

Why didn't you paint it bigger?
:confused:

i am going to assume that you meant = why didn't you make a larger screen.

i didn't feel like messin with it. i figured more gain would be good for bulb life.
and i had the money.

if someone is close to me. my diy is for sale, cheap.

It's still a good starting point. Better than starting from the factory settings.

I setup a user1 preference with the settings from the website and it toned down the flesh tones. They are more natural and not nearly as hot.

I should have AVIA II in the next day or so...

Just got my in-wall surrounds installed today the 20amp double gang installed and connected to the panel. Two CAT5 pulled and terminated. One CAT5 will feed a MIMO Dual Band (G/N/A) wireless router and the other is terminating in the equipment stack for the receiver and the HTPC. So all that is left is clean up and patching the walls were we had to cut out to fish line. WOOT!

The best video reference movie for flesh tones is Casino Royale

Some updates....

I have the patching process completed. Just need to paint:







There may be one or two patches that are sitting a bit proud. If they are too pronounced after paint I will knock them out and recut patch from the left over drywall and repatch.

My 20 amp service

Ahhh. To have a dedicated circuit to run amplification off of...

Now to get one of those magical $100 power cables that will make the 75 feet of 12/2 romex that I ran just turn into pure magic.

Uhmmm ... not to be a pest but those patches don't look ready to paint. Real quick I'll say that you need to sort of blend that in with some joint compound using say an 8" mud knife. Give it three coats with a little sanding in between coats. Spot prime with paint and then paint color on to entire wall after observing recommended dry time on can.

Otherwise you'll just end up with noticeable patches or you will have to paint twice anyway. This is sort of my 'area'. I would rather know more about A/V but such is life.
