Hello all.......

I am trying to use a projector for the first time since the wedding is next week and don't have enough time to create a Gobo for her. I am using a Photoshop Giff and VDJ 7.05 Slideshow video effect. I have the Laptop connected to the projector through the VGA output. The issue is that I don't only see the Gobo in the smaill video window but the skin of VDJ also. What am I doing wrong or do I have to connect it through the SVGA TV output from the laptop to the projector? The window where the Gobo shows is also to small it does not take up the whole screen. What am I not doing right? Thanks for the help.
 
Why are you using VDJ to control the projector? Set up the projector as an extended desktop screen in Windows, and use PowerPoint or similar to project the design.

Steve thanks for your reply. Doesn't the edges of the slide show when you use Powerpoint? A friend told me that was the draw back when using powerpoint..

If it's one slide, you can display it with just about anything. Use Windows Photo Viewer.
 
There may be some leakage if your projector can't go to true black (especially at the edges), the internal LCD shutter isn't designed properly or doesn't block the projector light at the edge, or brightness/contrast settings are off. These are independent of whether PowerPoint, Windows Photo Viewer or VDJ are the image source, so it's not a PP thing. I only mentioned PP as it has some transition capabilities if you have more than 1 slide, but any app that can display full screen will work, just slide it to the "projector side" of the Windows extended desktop and use the apps full screen mode.

To minimize the "framing", play with the brightness and contrast controls and be sure your slide background is straight black.
 
Yes I tried it and sure enough the square comes out. I will show it to the bride at the venue and if she likes it then its a all go. Thanks everyone for your help. I was originally using VDJ for it as another DJ friend told me it wouldn't show the square but I couldn't get it to display properly. Thanks everyone for all the help. I posted this on the other site and if I got 1 reply was too much. You guy's & ODJT rocks!
 
I utilize a PJ for my monograms.

Steve149 brings up some good points about tweaking your color and contrast settings, but I've found that most PJ's don't need much. A nice throw distance also helps in losing any subtle box effect as well. If you plan for a long throw, just make the image smaller.

This one was projected over 50+ feet.

outta curiosity
which projector are you using, and how much did ya pay for it?
 
It's an Optoma EP721/EP620 (same projector, just unique numbers depending on where you purchase it) and I purchased it from an individual used at a very nice price. You can usually find them on Ebay for a good price too. I like having duplicate back-ups so I picked up another one from there for less than $300. I create all monograms via Photoshop, so I'm not tied to having to order ordinary stock fonts/images. You can be much more unique and creative using a projector and software.

How long of a throw do you need on these Optomas? I'm currently shopping a new projector and leaning heavily towards a ViewSonic PJD7583wi. It's listed as a short throw, 3k lumens, and I can get a full 84" width at only 3'5" distance. Of course, it is 8-bills. EDIT: After looking at this I went back to Amazon and found a PJD7383. It's 1024pixels but still 3k lumens and I can fill an 84" width at 4'6". Price is $243. wow!

Your question needs more detail....what are you trying to fill?

To fill my 5x7 screen, I need about 15', which is a pain. For my video, I plan to purchase an InFocus IN1501 Short Throw Digital DLP Projector....that brings me down to only needing 5-6' feet to throw that 5x7 screen.

I purchase gear for purpose -- these Optomas, for the price, do their job that they are intended. That makes ROI very nice!

For projected gobos, a long throw projector is normally better. A short throw one (which I have) will hit 8' wide in less than 8' from the screen/floor. If you mount it on a T-bar or truss, at a normal 12-18' to the dance floor, you're going to get a really big and probably distorted image. If you are projecting on a wall .. then the short-throw may work to your advantage .. different throws for different folks I guess.

Randy, not sure if you've placed your order yet but check out the Viewsonic PJD7383. I believe you can fill that 60" you're looking at only a 3ft throw at a price of $253 (amazon). I've used a Viewsonic 5000-series that past year and that short-throw is extremely handy.

BTW, the short-throw projectors are being used for slideshow/texting, usually front-projected. I agree, a long-throw will be needed for putting a gobo on the floor. I've got an old Epson that has that part covered.

I think it would be just a matter of changing the size of the created monogram image to account for the different throw length.
