Multicast KVM over IP (Geffen 4K) works on GS105 switch but not on GS110TP
I have a transmitter and receiver pair of KVM Extender over IP from Geffen that use multicast. When the Tx and Rx are plugged back-to-back, they work fine. Proper operation: once making the fin...

Well, that's not a Netgear problem. Can't see any reasons for not enabling Jumbo Frames on a modern home, SOHO, or Small Business Layer 2 LAN.
Pushing either of FullHD (HDMI plus some additional data channels) over Gigabit requires compression and a very healthy GbE network, pushing 4K UHD over a Gigabit network is almost impossible without heavy compression and massive frame loss. Most vendors have similar requirements, even the leading edge ZeeVee ZyPerUHD does require IGMP multicast snooping and Jumbo Frames of at least 8000 - when transmitting a 4K stream they take up about 400 Mb/s bandwidth - with massive compression, with frame loss and ways off correct sync HDMI transmission.
Two non-compressed, no frame loss 4K video streams are oversubscribing the bandwidth available on a 10GbE link. That's why AV pros are going towards SDVoE on at least 10G (for a single HDMI) or with switch embedded HDMI for uncompressed, almost latency free 4K/UHD or HDR content distribution. Check out Netgear SDVoE offerings paired with ZeeVee ZyPer4K encoders, decoders, and embedded switch HDMI ports. Thic can't be cheap.
Thanks, I'll try turning on IGMP and snooping, and jumbo frames. But now shopping for a different solution since it requires jumbo frames.
