What resolution are you using?

Well, just for checking what these can do i wanted to try 1080p@60 but all edges were squiggly which leads me to believe the sync timings are too short, it stabilizes with 1080p@70, its what I took the screen shots of the rough set up earlier in this thread. I looked at the resolution editor program that you use to delete,change or add resolutions and their associated timings to the VP.. In the advanced section it shows what all the timings are for the resolution selected. here you can adjust all the timings similar to how a HTPC resolution editor works(I know how they look mike thanks to some of your posts on this )
So I need to adjust hose and see what happens. I hope its that and not the electronics being designed for specific use. I'd then have to remove those from the associated boards. I'll try straight to the PJ tonight from the player. at work now and about to leave.

PS how do you take a screen shot of a program so I can post the resolution editor of the TV-One unit?

I tried the LG BH200 directly to the moome card but it only sync'd up at the begining and once the 1080p signal from the actual movie started it lost sync.

Love this thread. Person I thought was the most intelligent I have ever met managed to get himself kicked out of the USAFA (Air Force Academy) then redeemed himself by taking 24 hours a semester & working full time at UT with mainly Aerospace Engineering classes. The Air Force wisely decided to take him back.

That does look just like PowerStrip. Are you just trying to use one TVOne now? I guess I'm not fully understanding what your doing, were you going to try a stack first, then move to a blend?

What resolution is the final goal to each projector when blending?

The Marquee will not be happy with the 0.297us horizontal sync width. Try changing the horiz front porch to 20 pixels, sync width to 140 pixels, and back porch to 120 pixels. That should work ok but you will probably have some "jail bar" ringing on the left side with the short retrace.

The variable caps on the VIM help to compensate for the low pass filter made up of U13 series resistance (red channel) and all the capacitances between U11 and U14 input. Use the variable caps to make one pixel on/one pixel off test pattern as near the same as possible to the one line on/one line off test pattern.

Signals shown are one pixel on/one pixel off series at 2048x1536@60Hz. Top trace is output of U11. Middle trace is input to U14 with no peaking. Bottom trace shows input to U14 with peaking circuit added.

The neck card is essentially another low pass filter that can be somewhat compensated for by (over)peaking the output of U11.

This mod gives enough bandwidth for pixel clock 240MHz needed for QXGA (2048x1536@60Hz). Standard configuration is a little low for 150MHz pixel clock or 1600x1200@60Hz or 1920x1080@60Hz.

Ok I tried your settings and I am getting the Jail bars but on 1920x800@72 i don't have them i have huge porch and sync setting though, the image is squished sideways but the size control on the pj compensates. Now for the blend(jsut messing with one PJ for now) i am not sure what to use for the Horizontal size from 1920, i think 1152 is what i should be shooting for right?
That be for a 10% blend zone on one PJ.... 1920x 10%=192 lines of blend zone 192x2=384 for the total blend zone so if i do 1152x2=2304 the subtract the 384 blend zone id get 1920.

But with the Tv-Ones I think I can go to a smaller bled zone thus using more of the full phosphor so i could try a 5% that be 1920 x 5%=96 , so 96x2=192 for a total blend zone. So that be 1056 x2 =2112 then subtract the 192 blend zone and I'll get the 1920. I Guess I'll look over the C2-2250 manual and blend zone guide.

I should also down load the blend zone calculator they have and mess around with it, Were is Boilermaker when i need him!!! I think he used 1152 per PJ?

Ok On 1080p@72 I am getting jails bars and increasing the porches and syncs does nothing, i need to move the image at least 3/4 inch from the left side of the tube face to get out of the "ring zone" that is just a big waste of phosphor. I still need to upload my custom settings for the blend and see if I get any ringing there. I guess I should not worry about it if in the blend it wont matter... but i hate not being able to solve problems!!! i guess thas why i have not done the blend yet little issues keep nit picking at me.

Also Bruce pointed out to me that when you press the info button* that the PJ comes up as a 8503? Scott what does this designation mean? is it specific to the 2.35 modification? Oh and this PJ now has 63 hours on it

Just out of curiosity (didn't read the whole thread here, sorry!), what was the original hour count? Was it a true 0, or does VDC run them a bit and doesn't reset the hour meter?

VDC runs them. They put them in a little booth and run them for I thought 100 hours, but maybe it is 50. I think they also do a set-up on them to make sure everything is running ok.

[tse]

Hummmm. I though they were burned in for 100 hours, too. They are set up for customer's video format, throw distance, and screen size. The Longbows are set for a very high resolution but it is an interlaced video format.
