NESRGB Question w/ xrgb-mini dimming when movement on screen.

Hi,

NES Front Loader.

So all my other consoles work fine. I bought all my cable from retro_games on eBay.

Tim's Scart cable didn't work for me because it was using 12v on the power line.
Retro's cable has a sync stripper that is expecting 5v so I had to create a new cable.

Now, I do NOT have any capacitors in the new cable on any of the RGB or Sync signals and video works.
I notice when there is full screen movement, the image is a little dim until I stop moving.
When I stop moving its fine.

So here is an example. When Playing Mega Man, as long as the entire screen doesn't scroll its bright.
He can jump around kill robots and its great. Once the screen starts scrolling it dims a little bit.
Once it stops scrolling its fine.

I'm trying to understand why that is happening. If it were a cap issue, I would expect the problem all the time right?

This is my setup.
NES w/NESRGB -> XRGB-Mni -> Denon Receiver -> LCD Projector.

All my other consoles are fine. Its just the NES that does this. I'm also not an expert on RGB or SCART by any means either so its a little black magic at the moment.

Thanks.

There is a pretty active thread on the nesrgb here:

Someone over there may have an idea of what's going on.

 

I've seen this on other LCD displays before. Not sure that there is any possible fix for it.
