I will check it out see what it looks like.

Perhaps I should cover the wall the the screen is on with the same Black Velvet that is on the Bezel.

Then over scan and black bars will not be an issue.

Thanks for the information about the 3.3% of screen width.

Is there a reference or website that shows this type of information?
It was calculated from the ratio of 4096 to 3840.

Yes cover the wall and you will never see the bars, but you do not have to overscan.

Hey Mike...I’m using the projector central site...when choosing 2.35 and and 120” diagonal screen with max zoom, the calculator tells me I need 12”5’ throw distance to fill the screen...I have 13 ft...What am I missing?

Put it to 16:9 and adjust image width until you get to 111" wide. You will see 13'-4". That is the required throw, if you want 1:1 pixel mapping. Selecting 2.35 you will use full 4096 panel width, gain some brightness, reduce throw to 12'-5", lose 1:1 pixel mapping and cut off a little bit of the image height.

DOH! Now how the hec was I to realize that setting to 2.35 was based on the full panel? Does it mention that? Probably does and my speed reading failed me! Thanks man, appreciate the info and quick response...

Not completely sure about how image frames are handled with either the native or zoom modes, I figured a scaled autocad drawing could help comprehension :

just hope this is what happens really :

Ok folks, I am now 13”7’ back...I Have aspect set to auto...on my 2.35 120” screen with max zoom, I can juuuuuust fill the sides (and overlap a wee bit) but the top and bottom fall a little short with a bow at the bottom Center of the screen...I can’t recall what the bow indicates is out of whack...any input appreciated...not sure why my sides are full but the top and bottom a little short with a bow...thanks folks...

Also when projector central says I need 13”4’ is that from the lens or from the front of the pj?

Also I know I can fill the screen with setting aspect to zoom, but that’s not my preferred method...

A bow indicates you are pointed too high. Small corrections.

keep in mind there is a variance, so not guaranteed to hit that size at 13'-4"

Thanks, so I did lower the pj but still bow...I put a level on the pj and it appears to be level...the other issue could be that I read is it bows when the Center of the screen is closer than the edges...I wonder if this is inherent in tab tensioned drop down design?

Thanks...but since the sides overlap, doesn’t it indicate some small tweak is needed somewhere in regards to pj and screen alignment?

Hmmm, I didn’t measure but I’m thinking an inch or so...I have a new tab tensioned screen...when I push the bottom Center of the screen in, where the apex of the bow is, it minimizes the bow...

- When you align the projector onto the screen, the 16:9 portion of the panel should perfectly fill the 16:9 screen. The black bars on the sides should spill off onto your screen border. Because JVC projectors have good black levels, there is very little likelhood that you will ever notice them


.
As I mentioned earlier this is not what I am seeing. When throwing the 16:9 image onto my 16:9 screen, once the top and bottom of the image fill the screen, I STILL have black bars in the sides. So to use the lens zoom to make the side bars spill onto my frame, I lose a littlle of the image on the top and bottom.

As Mike said, I assume either my screen isn’t 16:9 or the image isn’t 16:9.

Not sure if you can program in custom IP control commands with your remote, but if you can then it can be turned off with 1 command.
I believe the IP Commands also require dual send for off.

It's really not significant. It's maybe 75 lumens on low maybe 100 lumens on high by math. But is actually less because lumens measured at center of screen are brighter than at edges. Since this masks off the very edges, you probably lose about 50 lumens. It's not going to be noticeable at all.

Will the 1.5 inch bezel eat up the the black bars?

Walls and ceiling are going to be repainted with the renovation so hopefully any spillage beyond the 1.5 inch Bezel will not be noticeable if I go that route with the JVC.

My friend has an AV store with a NX5 on display so I will call him to see if he has cable or sat so we can feed

16 x 9 content.

If I am satisfied with the aspect ratio concern then my last issue will be about motion handling with fast moving sports.
Cable or satellite will never feed 17:9 to the projector. They'll be either sending 1920x1080 or 1280x720 both are 16:9 ratios and both will result in looking just like any other 16:9 projector. In fact, I have a 16x9 screen and just set the projector up as a 16x9 projector. If I watch 17:9 content, I don't worry about any zooming I simply have small black bars on top and bottom just like any other 16x9 display. You're worrying about something that's a non-issue.

Would a projector with native 3840 x 2160 chip be better for me considering that 16 x 9 sports is the top priority?



Right now the two projectors I would consider are the JVC NX7 or the BenQ HT9060.



I am starting to think that the JVC NX7 is better suited for movies and that the BenQ HT9060 is better suited for sports.



I need a demo of the JVC NX7 with either cable or sat input showing HD content to see how it fills the screen.
Get yourself a jvc.. your not going to see the bars but there is a learning curve setting these things up but once set, you'll be happy for years to come.. Trust me I've had projectors for 16 years now I owned 2 Optoma for a total of 12 or 13 years.. when I bought my first jvc 3 years back I upgraded every year all the way up to the 640, I was hooked like a drug addict, obsessed.. I even put a pre-ordered for the n7 back on Sept or Oct but ended up canceling after it got delayed..

Well in this case it doesn't.

Sending (0x21, 0x89, 0x01, 0x50, 0x57, 0x30, 0x0A) which sets the power state to off turns the JVC off in a single command, or at least it does for me.

It's not always simply the center that is brighter. It depends where you lens is compared to the screen. On my screen, the top center edge is about 0.5 fc brighter than the center of my screen because my projector is ceiling mounted with the lens in line with the top of my screen. So the lens is physically closer to the top of my screen than to the center.

Yes it's about 75 and 100 lumens in normal and high bulb (more if you have screen gain), but I don't know what you mean by masking off the edges. I'm not masking off any of my projector's panel area and my brightness does increase a little using the zoom mode. Plus I get a bigger image than I could if I didn't use it.

As Mike said, I assume either my screen isn’t 16:9 or the image isn’t 16:9.
Your projector may not be aligned properly for accurate picture geometry. These things are easy to check. Grab a tape measure and measure the width and height of the screen, then divide to get the aspect ratio. Do the same for your projected image. If your screen is 1.78:1 but your projected image is not, adjust the position and angle of the projector until you get it right.

Double Tone mapping with Panny 820

Hi folks...I’m ok with the TMapping settings on my N7...On the Panny side under advanced settings do u chose basic luminance pj and then simply turn Optimizer on? Are those the settings on the Panny to achieve double TMapping?

Hey folks any other ideas? I’m trying to have my picture fill my 2.35 120” screen...I’m on max zoom and the top is aligned, both sides are aligned, the bottom right is aligned but from bottom right to left bows up and misses the left bottom by an inch...thanks...

Edit: using a tab tensioned screen, if that makes any difference

Adjust your pitch, adjust your roll, adjust your yaw, adjust your lens shift. Compare results of how changing one of these things affects the others. This is just geometry. Keep adjusting until you get it right. It's going to be trial-and-error until it lines up the way you expect it to.

Thanks, so r u suggesting my mount is not perpendicular to the screen...? I can’t turn the pj when it’s in the mount...I can adjust yaw and pitch but can’t physically turn the pj when using the Peerless mount...given that r u suggesting to unbolt the mount and realign the mount?
