Monitor on left is the source; monitor on the right is what would be streamed. I don't have any filters on either source, but there's a dark shadow image on the right that isn't on the original. You'll notice that the last "1" on the top of the screen is shadowed on the far left of the second monitor. Shadow appears no matter what is on the display on the left (desktop, notepad, or MediaShout as shown). If I add a second source from a different computer, there is no problem. Only happens with this one. I'd be happy to include a log if you'd like ... just tell me which one you need the log for.

What is your actual setup here? You say your left monitor is your source... what are you doing to get this over to the monitor on the right? I can only assume these are 2 separate computers, considering windows 7/10.
We need more information. What's going on here? Include log files for both as well, please.

I'm having the same issue. Here is my setup. I have OBS and the NDI plugin installed on a laptop. I then have OBS and the same plugin on a PC. My son plays on the laptop, and I play and stream from the PC. I have both our screens up on the stream. There is a major shadow / ghost on his screen when viewed through the PC OBS/stream. I've placed a screenshot of the shadow. This screenshot was taken from my PC. There is obviously no shadow on his screen.

yes, that is the resolution of the laptop. Let me read through some posts to get log files, I don't want to ask here to get that info as I'm sure it's already available.
edit: Here is a link to the log file of the PC that streams: https://obsproject.com/logs/qxDUd0sdVh4cdlvP

and here is a link to the laptop file: https://obsproject.com/logs/wq9asxBVUDNy0nFj I do notice that the resolution on the output of the laptop is strange (due to looking at the logs), but want advice from the pros :) let me know what you think and thanks in advance for your help.

As a general rule, you want to keep your horizontal and vertical resolutions as multiples of 8, due to how the encoding process works. Each frame gets split up into 8x8 blocks (known as macroblocks), so if the frame can't be nicely split, it results in leftovers. Apparently somewhere in the NDI encoding process, it's putting the remainder in the wrong place.
The first thing I would try is updating your NDI tools, as it seems you're slightly out of date from the most recent version.
If a quick update doesn't fix it, then change your output resolution on the laptop to something more encoder-friendly, like 1080x608 if you want to remain close to what you have already, or 1280x720 for a more standard resolution.
