Thanks all for your posts - great to find a useful resource and an explaination of what I was seeing. Just to confirm the behaviour I've seen here:
1. SBB-NT plugged up via RGB to a standard desktop monitor, MagicInfo-I refuses to connect to server
2. Move SBB-NT to Samsung LFD plugged in via HDMI, connects to server, behaves as normal
3. Move SBB-NT back to desktop monitor, no connection
4. Repeat step 2 just to check not going nuts - works perfectly
The client I'm working for had bought seven of these to drive legacy displays moved from their old building.
The SBB-NT only works with MagicInfo-I if it's connected to a Samsung LFD (Like the 460MX-2 or 650TS).
Chris, I assume Samsung said this is by design? i.e. no way around it other than to switch everything back to MagicInfo Pro? (which would be an immense pain with 37 screens already configured with MagicInfo-I)
Now to break the bad news...
