Hi everyone!
Im new to the forum and hope to get some help. Im the lucky owner of a marquee 9500 lc ultra, but Right now i have a couple of questions.
My screen is 134 cm high and the width is 234 cm.
How far away from the screen is the projector suppose to be placed. And how far away is possible without disturbing the picture. I couldnt understand the formular on the curtpalme throw distance manual. So please if someone could tell me.
Is there a possible ceiling mount for the projecter that can keep it as close to the ceiling as possible. The mount that I have right now is not working in my favor!
help will be greatly appreciated!

There is only one correct location to mount a CRT in with relationship to the screen. How close you can keep it to the ceiling depends upon how high your screen is mounted.

In the spirit of teaching a man to fish, what about the formula confuses you?

I live in europe and crts are not that common here.
I was hoping to put it about 5 meters back againt the backwall and maybe be able to zoom the picture into the screen. But im a newbie so all info is appreciated! The thing is on the formular when I write the measurement of the width the value of the height does not correspond with my measurement. And we use the metric system and i dont think it works in this formular.

NO! There's no zoom lens on CRTs! The throw distance is APPROXIMATELY 1.4 X the width of the screen. THat works in metric as well.

okay can I settle with the approximately measurement or does it have specific measurement?

Nobody said it so I will....Welcome to the Funhouse moby! Thumbs Up

You got your hands on a very nice projector. No starting with a 7" for you and working your way up eh? Laughing

It seems very daunting at first but if you got the projector from someone who knew what they were doing, and assuming it was optimally set up already, and assuming it didn't get delivered by DHL....most of the hard work should be done for you. In a nutshell, you want to mount the projector at a distance that uses as much of the tube face as possible WITHOUT running the image off the edges of the tubes. You'll also want to check to make sure there's a small air bubble at the top of the LC chamber (a special clear glycol coolant) with the projector in the floor mount configuration.

The Marquees are very easy to set up and maintain once you get past the initial confusion of setting it up. After you get some type of source connected (using one of many choices offered on the main site page in the Featured Items area: http://www.curtpalme.com/ you'll need to follow the steps in the manual here:
http://www.curtpalme.com/ElectrohomeMarquee_Downloads.shtm and go through a setup over and over. Each time you go through it you'll learn more about the machine and it's nuances, and the image quality gets better and better.

How do you plan to mount it to the ceiling? Many of us use Uni-Strut. Most commonly used as a highly configurable industrial support hanger. If you have the room you can go with a factory Marquee mount. There are differing opinions as to cost vs functionality between the two methods. Some people just don't have the headroom to use a factory mount.

Get a copy of Digital Video Essentials here: http://www.curtpalme.com/CRTforSale.shtm for good setup patterns in different aspect ratios and resolutions, and maybe a copy of Grahams CRT PJ setup DVD here: http://www.curtpalme.com/SetupDVD.shtm He doesn't show a Marquee being set up but most everything can be crossed over if you squint a little bit. (American humor might confuse you there). Rolling Eyes

Also check out Kal's most excellent Grayscale guide here: https://www.curtpalme.com/forum_archived/viewtopic.php@t=10457.html or click the link to the left of the DVE ad (from the link above).

I'm not anywhere near as well versed as some of the Marquee guys but it's nice to be able to contribute what I do know for once.
Nice machine. I'm jealous! Thumbs Up

I would also like to add that if this is your first CRT, and it sounds like it is you should set it up on the floor first to become used to the controls and the process of setting it up. This will make it much easier to setup when it makes it way to the ceiling.

There's also differing levels of 'setup'. What looks O-Tay to one person may look like a bag of ******* to another. I'm 'just OK' with my setup now that I've been at it a while but I've racked up a good 1500 hrs on it since the last complete setup.

I just need to stay away from HT meets and I'll be happy with my efforts forever. Laughing

Then again....look at all the good grub I'm missing out on by not attending. Laughing

In defense of draganm's comment, not that he needs me to defend anything he says, I would say I'm at the point where I would consider a pro ISF worthy of the $$. If I had it done as soon as I got the pj I probably (definately) would have dicked it up and wasted the pro's time and my money.

Half the fun of having one of these things is the putzing with it and the gratification that comes from finally 'getting it'.

Oh yeah....I'm still jealous. Mr. Green

Wow. I'm kinda surprised at some of the negativity here. If you dont want to help then thats fine but dont throw water on his fire. I'm sure there are many others on here more then willing to help him through the process.

As far as the throw distance, lets give him the correct process. If screen size is already chosen, then fire up the projector and turn off the blue and red tubes and concentrate on the green. Learn how to center and maximize the raster on the green. When that is accomplished then project the green image on the screen and move the projector forward or backwards until the image fills the screen. Now you have your throw distance and no math was involved and it was accomplished correctly.
