I had 3 video sources going to port 5 (5 BNC Analog) on my projector via a Lumagen HDP Pro. A DVD player (analog out) scaled to 960P, a sat receiver (DVI out) at 1080I, and and a XBox360 (analog out) also sent to the projector at 1080I. I recently purchased a Toshiba A2 HD DVD player and used the analog out at 1080I. Everything was peachy.

I decided to add some memory settings to my HDP Pro and run through the projector setup again. I know just enough to be dangerous.........somehow, I'm not quite sure when it happened, but all of sudden during my "tweaking" my Xbox picture and HD DVD picture (1080I) have shifted to the left..........looks like the H phase has shifted the picture left.....maybe 10%. The 1080I sat picture and the 960p DVD image are still centered. I can shift the HD DVD to the right via the h phase, but then the images that were ok are then too far to the right.

All the 1080I outputs have a Vrate of 59.94 and a Hrate of 33.732 The DVD output does a Vrate of 59.94 and Hrate of 59.964. The Barco has two port 5 memory blocks. One at 60 / 33.6 used by the 1080I sources and a 59.9 / 60 used by the DVD source. When I was "tweaking" one of the things I was doing was messing with the memory blocks on the projector. Not sure if this has a bearing on my problem or not.

Anyway, I'm lost. Don't know if it's a projector setting or a scaler setting. 2 of the 3 1080I sources shifted.......why not all three, the output settings are exactly the same. THe only thing different is the one that doesn't shift is a DVI input to the scaler, the other two are analog. What did I change that caused all this? I really don't have a great understanding of Vertical and Horizontal freqs., but I do not believe I told the scaler to do anything "special".

Sorry for the long msg.....not sure what info is needed.

Oh yeah, if I select 720p output from the HD DVD, instead of 1080I (via the DVD player setup Menu).......the picture is centered. Picture is not as sharp as 1080I, however.

OK..........I guess this means the solution in not obvious.....I guess that makes me feel better.

I believe the problem has to do with the Lumagen, although I haven't figured out what. I bypassed the Lumagen using the HGfury and the shift went away. The shift shows up as a black band in the raster with the Lumagen.

FWIW, I went Toshiba HD 2 ---->HDFury Green Powered (via a HDMI/DVI 3ft cable) ----->Port 5 Projector (via a 25ft good quality BNC cable!) and I have one of the best images that I've seen on the screen. Certainly the most "3D". This was straight 1080I from the DVD Player via the Fury and quite a long analog cable. I guess that says something for the HDFury.

Still not sure why I get a shift going through the Lumagen....even in pass thru mode.

Could be you need a firmware update ...
