Created: 2017-10-11T09:44:09Z
I checked all the issue both open and closed to see if it is already fix or already posted:
#31 and #32 solution didn't work for me (more info below).
#49 and #50 kinda same problem but I am using windows.
#54 kinda same problem but with different setup (more info below).
#58 not the same problem because my PC1(gaming pc) SHOWS UP on the sources on the PC2(streaming pc) but showing a black screen.
I have 1 Gaming PC and 1 Laptop for streaming.
Setup
Both my pc and laptop are connected in the same network that support gigabit connection.
Both are using Lan Cable Cat5e that support gigabit connection
Both are running in windows 10
Both are running OBS 20.0.1 64 bit version
Both are running obs-ndi-4.1.3
Both have a resolution of 1364x768
Both windows 10 are up to date including drivers.
Both are using intel core I5 and base on my research it support ssse3
Specs
Gaming PC
CPU: Intel I5 6th Gen
GPU: GTX 750ti

Problem
NDI Source on my STREAMING PC can discover my GAMING PC but it only shows a black screen with a red dot on top left corner.
NDI Source on my GAMING PC can discover my STREAMING PC and it works properly with no problem.
I tried:

To disable windows firewall on both pc like the solution on #31 and #32 , but the problem still exist.
To used the NDI studio monitor on my streaming pc and it works perfectly fine (it can capture both video and audio), but the obs still showing a black screen.
To connect the lan cable directly from my pc to my laptop but the problem still exist (so its not a router issue).
To check low bandwidth, problem is still there.
Re-install both the obs and obs-ndi, but problem is still there.
Disable avast anti virus on my gaming pc (because my avast has a firewall setting so I thought it might be the problem), but still the problem didn't go away. Streaming PC is freshly installed so there are no antivirus and have plenty of free space.
Change my router (my ISP company provided me a new router LOL). problem is still there.
Tried to format and Upgrade OS on my streaming PC, when i first tried the obs-ndi-4.1.3 the other day, my streaming PC has a windows 7 ultimate and it shows black screen so I thought it might be because I am running a windows 7 version when my gaming PC is running windows 10. So I decided to format my HDD and install a fresh windows 10, but with no luck the problem still exist.
Tried to used a static IP and change my dns (because one of the users from 1 of the post suggested it) but problem is still there.
used a new cat5e lan cable (included from the new router provided but my ISP), problem is still there.

IMPORTANT NOTES:
there is a 1 time, for some reason my streaming pc suddenly shows a video instead of a black screen (shows my gaming PC Display) but after a couple of minutes the video freezes, when I tried to delete and add NDI source, black screen shows up again.
feel free to ask more about it or if I can provide more information like logs or something.

This had been happening pretty often to me since the first day I sue NDI.
I am using Linux Ubuntu 16.04 LTS as my Streaming PC and Window 8.1 for my Gaming PC.
This happening on all of the ndi version I gone throught but I am using the lastest right now just to be sure.
So, It always takes me about 30m - 1 hour of resetting everything for the Streaming PC to capture.
In case you don't know, here is my OBS setting when I add a new source on the streaming PC

And my Gaming PC

Now, what really interesting is that while the Streaming PC did find the Gaming PC, it showed a black screen to me.
Both of the laptop are connected through a Router, a TPLink TL-WR940N
Second thing, I got all of my Network Adapter disabled on my Gaming PC when I set up the stream.

Now, what really interesting is that by seeing through Task Manager on my gaming PC, OBS didn't sent any packet whatsoever.

I also have a WireShark data file which is proving this to be true I assume.

Even it is short, but that's it. No more interesting data showed up when I put this on 1 hour  (And forgot to save it)
I had tried every possible sync setting and the result are all the same. Sometime it randomly worked for no reason.
There need to be a solution for this, may be find a way to trigger the NDI source to fire up some packet to a targeting pc?
