i am refinishing my basement as we speak. unfortunatly after i am done , my ceiling height will be under 7'. my room size is 23x13.5 and im trying to fit a 100" screen. i have 0 light entering the basement. is the ceiling height going to be a problem? i did the calculations on with the mitsubishi program and it says that with a 100" screen my screen will be about 1 foot from the floor. is that suficient? someone please let me know if this will work. would it be better to get a 92" screen?

I have an 8' ceiling but because my room is a bonus room over the garage the pitch of the roof causes the walls to angle in sharply. That is dictating the size screen I can have. In my case with a 92" screen the highest I can mount it (because the width of the wall) is about two feet off the ground.

If I have used the calculator correctly then to achieve that I will have to add an extension to the projector mount of around 11" or so. If I flush mount it on my 8' ceiling then the bottom of the screen would be very close to the floor like your case.

When I researched the question about screen position I found that even 2' from the floor is generally considered too low. It especially makes viewing from a second row difficult unless you have a riser for that seating high enough that folks in the 2nd row can see the bottom of the screen over the people in the first row's heads.

You just need to angle projector up and use keystone. That's what I did and my HD1000 looks BEAUTIFUL.

You can angle the PJ 6" to 8" without the use of keystoning. You would have roughly 1/4" on either side at the bottom on the image that would be misaligned. Hardly noticable. If it is then you can keystone a hair.

The mitsu does an excellent job with keystoning and not losing image quality. My ceiling is 7'-8".

Digital Keystone on modern projectors only shows up as a deficit on things like Windows Desktops or high-resolution patterns (ie:Test Patterns).

For movies, games, etc you'll not be able to tell the difference between an image with keystone ON or OFF. The solution here is to hang the projector, angle it up slightly, and correct with a notch or two of digital keystone correction.

There are some who swear they can see a huge difference in a picture with keystone on or off. I've stood 1 foot from my screen, frozen images from DVD and HD, and turned keystone on and off..and can't for the life of me see anything different in the image with keystone on or off. <shrug>

Amen! I've posted so many times on this it make my fingers hurt. Search my posts and you'll see a thread I started specifically about why digital keystone correction can be used and why your image STILL LOOKS GREAT.

I agree with the previous posters that using keystone isn't really an issue on the HD1000. For a quick test, I placed the HD1000 about 2' off centre and at the same height as the projector it was replacing ( a 0 offset 960x540 Mits hc3 ). Even with 6 clicks of V and 8 clicks of H ( something you would never do in real life ), the HD1000 was much sharper in a side by side comparison with the hc3. It was also not much different on video material than no keystone at all ( when comparing it to itself ).

With just a few clicks of vertical, I can't tell the difference on HD video material at all.

The don't use keystone and live with the trapazoid masked by the screen border approach works well too. It's a bit noticable on 4x3 material depending on how much you tilt.

Do any of you that are using the tilted method with Keystone, have any pictures of your setup? screenshots?

I was wondering the same thing. I would love to get this PJ, but with a desired 116" screen and 8' ceilings I am worried, and I really don't want to sacrifice screen size to accomodate a PJ when there are others than can fit the bill

I agree with HeadRusch. I don't see any problem with a little keystone adjustment and movies. I use my PJ for Video editing and the effects on the desktop are not pretty, however. So no keystone for me.
You might consider the HD70 which has considerably less offset. (AFAIK)

HD70 = 28%
HD1000U = 33% (I've also read 35%)

I have a 7' ceiling in my HT. The HD70 is 11' 10" back and the screen is 13.5" down from the ceiling. The PJ is 3.5" down from the ceiling. The screen is 100" diag. The picture does not quite fill the screen (about 1" border around).
And there is a very slight bow up at the bottom of the image which no one else can see but I know is there. ;)
The way my HT is shaped (trapezoidal, and then some!) I was lucky to get the HD70 to fit at all. And when keystoning is used the image shrinks. I am zoomed all the way out and the PJ can go no further back in the room.
I am liking the results every night. Great PQ.

My screen is 58" x 103" (118" diagonal)

Before I used and IN76 with 4" tilt up. The 1/4" "out of square" image was impossible to see since it dumped into the frame.

Now I have an HD1000 (interim PJ until 1080p this summer). I use the same mounting and screen positions. I now tilt the HD1000 up quite a bit. I have about 3/4" spill into the frame at the top of the image. I have not even bothered to do keystone to correct it. It is next to impossible to detect.

Don't let the offset of the HD1000 or any PJ concern you. The above image is from the IN76 with a low res digital camera. I will do another with the HD1000 soon.

Kevivoe: That is a beautiful Home Theater. (other viewers should click on it to see it large)

Did you superimpose the Finding Nemo image?

Again, your room looks great.

My screen is 116"wide with a 8' ceiling and I even have it hanging on a 8" pole and I only need 5 clicks out of the possible 40 for the keystone. And the picture is 9" from my ceiling.
As I have also said before, picture quality differance is not noticable.

No I did not superimpose the image. I just took two more with the HD1000u and Brilliant Color setting of 3. Very good. My screen is my own design (mix of paints on skim coated drywall).

This is the link to my photo gallery here at AVS. I have descriptions of my set-up and a few pictures of the projector, amount of tilt, screen, and screen images. In normal video with -11 on keystone I can see no difference between the image with no keystone and the -11 setting that squares the image.

Very Nice setup Kevivoe! beautiful layout. If you wouldn't mind, could you please take a shot of HD1000u in action with maybe a tv program (sports preferrably) and some ambient light? I plan on watching sports among other things with my setup and I would like to see how well the lumens of the HD1000u do with ambient lights on.
Thanks in advance.

PS. It sounds like Cyrano and I share the same issues as far as room lay out goes. My room is upstair in a Cape style house with a trapazoid shape. The room is 14'x 18' and the screen can only be as big as 92" since the two pitched side on the trapazoid prevent the screen from going higher. As it is, the screen would be 29" from the floor. Im looking at a fix frame 45" x 80" screen which would more than likely have 2" borders all around.

Give me a couple of days. The HD1000 has "sports" mode that I use. If you can wait until this weekend I'll have some hi-definition sports opps.

I read your post about keystoning and it was really enlightening. I did with my set is ceiling mounted raise the pj for higher screen a little bit (just a little) and then keystone by only 2. There was not any difference at all with or without keystoning.

Thanks for sharing nathan,
more power to you. Hope you continue sharing. :)

...if I have used the calculator correctly ... I am interested in the 1000u as well and have downloaded the calculator program from the Mitsubishi site. There are 2 projectors at different distances to the screen shown. Does that mean that the zoom lens can cover that range and the projector could be mounted anywhere in between, to get the same screen size and height from floor? TIA.

if you are going to have a fixed frame screen you could just tilt the top of the screen out to match the angle of the projector and you will not need keystoning.

if you are going to have a fixed frame screen you could just tilt the top of the screen out to match the angle of the projector and you will not need keystoning.I am wondering why people are not adopting this (tilting the screen and the projector together) as a recommended "optimization" practice. It should be desirable to have the normal of the screen parallel to the straight line joining the eye of the viewer and the center of the screen. Not as good as curved, but better than having the screen parallel to a vertical wall but centered above the viewer's eye position?

i just ordered the 92" screen. for my set up with the 7' ceiling i think this work work the best. i can always upgrade or make my own bigger screen later if all works out. this is my first projector project so i would like to test things out, and i got a good deal on the mits hd1000 and an elite 92" screen from projectorguys.com. $1350 shipped to my door with the projector, screen, 25ft hdmi cable, 25' 3-RCA Component Video Cable , and projector mount. this is almost half of what my local audio video stores were charging just for the mits hd1000 and a 92" screen, not including cables and mounts.

As a first time projector owner, prepare to be BLOWN away. All of us can remember our first times. Ah, the nostalgia. I became addicted to front projection with a horrendous (horrendous by Mistsubishi HD1000 standards) Epson SVGA LCD business projector. There wasn't anything good about the image except that it was up there on my screen and it was huge! It's going to be startling for you when you see all of that 92" of glory. Make sure when you get it set-up the first time you watch anything that it's night time or completely dark and make sure it's some cool HD show or HD movie. Animated movies in HD are CRAZY good. Plug in Art's settings he used when he tested and reviewed the HD1000 at projectorreviews.com. That's a good calibration to start with.

Oh and I almost forgot. Make sure you're sitting down when you turn it on. That way you won't run the risk of cracking your head open when you pass out. This is an unbelievable time to be getting into front projection. The stars have aligned. Price, performance, & ease of use.

Oh and another caution. When showing off your home theater to friends, be extra caution of friends that spent $3000 for a 50" plasma. They can become suicidal when seeing an image twice the size, just as vibrant and eye popping, at almost $2000 less. It is such a tragedy to watch the torture in their eyes.

Im dieing to get my first projector going... few more weeks and I will be ready for mounting!
