Does anyone have a suggestion for an affordable 4 or 8 port switch that works NDI? I only need to connect two pc together. I have a Netgear GS105 but it introduces about 500 ms latency, i am guessing my switch does not have full throughput.

How have you explicitly measured that it's the GS105 that is adding 500ms latency (and not something else in the chain)? Surely it would have to be buffering rather a lot of NDI data to do that.

If i conect the PCs directly togather without the switch thare is no noticeable latency. I also tride with the switch part of a 4g router and it also head latence. Useing vMix desktop captuer on one pc and vMix on the other.

I'm happy using https://mikrotik.com/product/crs112_8p_4s_in
It offers POE for the NDI encoder if the encoders can be powered through PoE
If you don't need PoE you can use the cheaper model https://mikrotik.com/product/CRS112-8G-4S-IN

This seems highly suspect. A switch doesn't have that much memory. It's backplane bandwidth is much higher that it's bandwidth available to a single port.

You might check to see if one system has not negotiated a gigabit connection. Perhaps you have a bad cable?

I'm having good results with the draytek vigorswitch p1092. It's not a well known brand, but I chose it after having troubles with multiple brands like netgear and ubiquiti. Ubiquiti overheated after a few days and didn't have correct POE readings, the netgear switch was too limited in it's gui to give all info that i wanted about power draw and stuff.

No problem to pass 8 NDI signals over this draytek switch, it has POE+ (25 watt) and has SPF if needed. It's very silent, and I have it running for months already without a single problem.

If you are still looking for a solid solution and dont want issues with dropped frames and errors go with something like a cisco SG300 or 350 10port POE. Quiet, POE, Solid, Multicasting blah blah. You can sometimes pick them up on ebay for a good going rate. Just make sure to avoid the 10/100 ones and IMO a switch without POE can be cheap but after a while you will wish that you got a POE model. I hope that helps you.
