After having the 1209s for three months,I finally decided to setup to put it into service. This is my first exposure to a Barco in particular a 9"LC machine. My setup is rather crude and there is still much to do to get this baby to perform at its best. It took a little trial and error to get the hang of the Barco setup but I finally managed to get a watchable picture.

WOW!! is the best way I can describe what I'm seeing. Now I see what the hype sounding having a highend 9"LC projector is all about. The brightness, crispiness of the picture, color detail and depth of image is breathtaking. It's like seeing my Blu ray collection for the first time. I can't wait to see what the picture is really like once I perform a proper and complete setup on this baby.

Like I said I just perform a basic setup to check things out. The focus isn't dialed in fully,convergence is off somewhat and the astigmation needs to be done so there's still much to do to get the best out of this great projector. I've been reading and studying the Barco info in the advanced procedure section. I'll be asking a lot of questions I'm sure.

Now for a few questions:

What's a good test disc to use to to help me perform the astig adjustments and to get focus exactly right?

Also is it best to adjust my rasters with the lenses off?

And I remember reading that it's normally safe to have the raster slightly off the tube faces as long as the picture image stays on the tube face. The picture image extending beyond the tube edges could cause the tube to implode. Is my understanding of this correct?

Thanks for any and all help guys

Well thats in most cases Kal, but in some instances, moving the image or adjusting the size can move the blankingwhich is something ive seen on my CineMAX.

Also, if you create a new duplicate of an input, the blanking is turned off, i had a source that the projector locked onto as close enough to another input that used different porches, and the image was off the edge of the tube face by a reasonable amount.

Thanks for the information. I'll be doing a full setup later this week and I expect it will take several tries. The centering of the rasters shouldn't be too difficult, it's the astig setup I'm sure is going to be the most work. I'll be back with any questions if I run into a roadblock.

There is also another side to this I found out so you have to chose. By making the image a little smaller you have to move the CRT a little backward and the lenses are turned less inward. The convergence gets a little relaxed in the edges.

So maxing the image gives more light but takes more power. I just stay within the phosphor with the raster to be sure and use less optical and electronic correction. I think the convergence effect might give a little bit more phosphor use? Less trapezoid?

Yes I see. Another thing. I've always used a genlocked pattern for convergence so that you're converging past the active image and so the image itself is more likely to be bang on. I seem to remember plenty of people saying not to do this cos the internal patterns are useless but I don't understand why. Converging with a test pattern off dvd or pc (not the genlocked pattern) you're not converging wider or taller than the image. I guess this means less convergence stress but I'd bet it's harder to get the edges of the image bang on.[/quote]


Thanks I'll try this out.
