hi just bought hdmi extender the receiver not showing image thru network
but works when direct connect thru lan. the hdmi extender spec support tru network.

here’s my setup
down stair : BTU to router to switch (upstair).
then switch to my pc.
hdmi transmitter from pc to switch, then the hdmi receiver from downstair
router to tv.

it seem something incorrect between the router n switch
thanks for help from expert from lowyat

Laaa... HDMI extender utilizes CAT5/6 cables. But never thru LAN!! Transmitter and receiver must connect via CAT cable, no switch in between.

u can connect thru in between network cable only.. cannot go thru router

The extender has its own DHCP server at the transmitter part.

spec can go tru switch

TV connected to router or switch?

Switch can but cannot have another DHCP server device in the same switch. The transmitter is a DHCP server. That's how multiple receivers able to work with just 1 transmitter.

router with 4lan port (downstair)
connected to pc (upstair)
any workaround method ? i only got one cable between upstairs and downstair connection between router and switch
thank you for help

arju Does your HDMI extender have a DHCP server? If so, you'll need to turn it off and set all of them to get an IP address from your router.

Alternatively, you can put all your HDMI extenders into its own VLAN.

What brand & model?

it says the externder is UDP data transmitter

I guess you not using managed switch, so no VLAN kind of thing here. Starting from simple way, turn off the router left just those extender and your pc connected to switch. Then if this is working mean the extender have it own way to search for others receiver, separate your router and those extender to 2 different switch.

But if you are using managed switch, then could be a lot of setting needed and i'm not expert on this.

ohh, mine is not managed switch, normal gigabit switch
