  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Anyone using FLanders Scientific LM-2461W for 4:4:4 3Gb/sec SDI monitoring?

If so can you list your Decklink settings and monitor settings? I'm getting funky colors on the FSI when it's set to Video: SDI Format: Auto.

When switched to Video: SDI Format: 4:4:4 RGB... I get no video signal. Davinci Resolve is set to output RGB 4:4:4 Single Link.

Looks like the problem is that Decklink HD Extreme 3D+ is not SMPTE 425 compliant. This royally sucks. The 3 Gb/sec SDI on the Flanders Scientific LM-2461W is Level A SMPTE 425M-A or Level B SMPTE 425M-B.
 
Well I communicated with FSI via email and God bless them, they tried to help me to their best ability but the problem really lies with Blackmagic. Looking at the spec of the Decklink Extreme 3D+ and the FSI LM-2461W monitor it's clearly apparent that they are not the same SDI standard. Of course if someone on here has it working in (3G) mode "properly"... I would love to know how. Waiting until the morning to call Blackmagic due to offices closed over weekend.
 
hmmm. Well that sucks Andrae! If it is of any help, I've got the FSI 2470 10 bit monitor and have no problem displaying 3G out of the Decklink Extreme 3D+ card. So if FSI has shifted thier standard implementation of the 3G SDI, you can let them know that what they did for the 2470 worked fine with the BM card.
 
FYI- I was just on the phone with Dan at FSI and asked him about this. He said they were expecting to come out with a firmware update sometime very soon (this week) which addresses this. Since they learned of the problem a couple of days ago, I'd say this is pretty responsive customer service.

Yeah these guys are rocking. I found out directly from Blackmagic that they do not support SMPTE 425M Level A. Strangely they reported that SMPTE 425M Level B is supported. Of course that's probably what's causing all my issues.

Johan is sending me a new firmware update for Level A support only... with the news from BM don't know if this will do any good... but about to test it.

Was it reporting (3G) on the OSD? Got an email from Blackmagic stating that they they don't support SMPTE 425M Level A. I don't know why they would support Level B and not A. Pretty darn strange.

is it just the 3g sdi not working or dual link doesn't work either?

This issue is just related to the single link 3Gb/sec 4:4:4 RGB. The FSI LM-2461W does not support dual link. For the last six weeks I thought I was getting a proper 4:4:4 single link 3 GB/sec. Recently I was told that if it doesn't say (3G) on the OSD... then it's not a 3 Gb/sec signal. Since I had Davinci and the Blackmagic card set to push out a 3gb/sec, I spent the last 6 weeks thinking I was good to go. It's only when curiosity got the best of me and I wanted to compare the color quality of 4:2:2 vs 4:4:4 that I found out all this time I was only getting a single link 4:2:2 signal. Don't know why a proper image still displays when Davinci and BM are both set to push out a 4:4:4 single link signal.
 
Folks unless FSI can come up with a firmware to switch a SMPTE 425M Level B signal into a Level A... I'm screwed. I will have to get an AJA adapter to convert the signal... unfortunately the adapter cost $1000. It's really amazing how incompatible these devices can be... you would think it would be a standard.
 
I also talked with FSI yesterday, and they will release a firmware this friday. The panel will then accept level b signal from the decklink extreme 3d.
 
Any word on the firmware release?
 
Just got an email from FSI with beta firmware 0.9.40-1708. The firmware has a new "Overlay" option in Menu\System\3G Level B. This pretty much solves the issue of Blackmagic cards not outputting a 3Gb/sec SMPTE-425M Level A signal. I've asked Johan if there's any quality loss using this method. Still awaiting his response.

Update:

Official firmware release due later this week. They are quality checking the current build so no word yet on the quality of this overlaying method versus a normal SMPTE-425M Level A signal.
 
HI Andrea

So you managed to connect the Flanders to 4:4:4 SDI?... That's always in 10 bit right...

Glad to know its working well.. Would you be so kind to do a little round up of your setup once you settle it.. Really interested in a similar setup.
Thanks in advance
