|
|
I have noticed that the left side of the picture is being cutoff. I have all of the blanking set to 0.
If I change the size, it just changes the raster size. Not the displayed image. If I use phase to move the image to the right I see noise etc on the right edge as it seems to be at some sort of limit. I can still move the picture with phase so that I can see that on the left side there is much of the left image being "cut off".
What can I do to get the entire image "centered" upon the raster so nothing is cut off?
Thank you
Darren

I wonder if the Buf2000 would help you with it's variable sync settings?

There is a tech bulletin on this issue. The entire picture can't be displayed at once with any combination of control settings. The fix isn't too difficult but you'd better be good with a soldering iron.
Unfortunately I can't recall where the tech bulletin in question is posted. I'm sure someone will link to it.
The problem affects most 8000s and a lot of earlier 8500s and 9500s, IIRC.

My source is from an HDMI pre/pro into a moome dvi card. With 4 different sources. This was happening though when I was using 5bnc vga input also. Maybe there is just something screwy and I need to do a complete reset. I need to set aside an afternoon in that case.

I am pretty good with soldering. Now if I could get that link to the bulletin... 
Thanks

For the highlighted quote above, are you setting up separate memories in your PJ for each source?
Sometimes the timings are not the same from Pre/Pros. Some scale them to the exact same output, others just pass
through the signal to the display and allow the display to handle it and if this is the case you will need all new set ups(memories) for each source, some may be similar and need less convergence touch up.

I am using basically 2 memories. One for the HTPC and one for the pre\pro. All of the devices (except HTPC) (STB, BR player, (the occasional PS3 for Rockband) show the same display.
I have my pre/pro set to scale the image. Remember though, it was doing this when I just had only 5bnc's connected. I just havent gotten around to trying to correct this til now
Thank you
Darren
