Teranex Mini 444 issue

PostTue Dec 20, 2016 10:54 pm

Sending the Teranex Mini a 444 signal results an improper picture (refer to picture). My setup is sending signal from DaVinci Resolve to Teranex Mini to Monitor.

Hardware includes DeckLink 4K Extreme 10.8.4. Teranex Mini - SDI to HDMI 12G 4.7

Sadly today's update (5.0.1) doesn't address the issue.

Are you sure it's the Teranex and not the DeckLink (or DaVinci)? I'm seeing something similar if I try this:

DaVinci Resolve, 444 enabled > DeckLink 4K Pro > SmallHD 702

Does the monitor support a 444 signal and has it been set up to receive a 444 signal?

In my case with the SmallHD 702 there are no settings for chroma subsampling and the specs say:

HD-SDI input: RGB/YCC 4:2:2 and 4:4:4, 1080p60, 1080i60,1080i59.94,1080i50, 1080p30, 1080p25, 1080p24, 1080p23.98, 1080pSF23.98, 1080pSF24, 1080pSF25 , 1080pSF29.97, 720p60, 720p59.94, 720p50

If I remove the teranex from the signal path than all is fine. The downside is I am using the teranex to display a calibration LUT for my monitor. For the meantime I have to send out 422.

Were you able to get this working? I'm now using a Teranex Mini SDI to HDMI as well and having the same issue with 444.

444 through HDLink Pro 3D is working perfectly with a DisplayPort to HDMI adapter, but the Teranex connected to the same monitor gives the wrong colors.

Does the HDLink Pro convert to RGB perhaps, while the Teranex stays in YUV?

Hi Patrick,

I have exactly the same problem !
I contacted the support and i have been told, BM is investigating but there is no ETA. For me is incredible (i remember very well the what happened with the HDlink Pro).

Your post is from December 2016 and 7 months have passed....

Did you get it to work in some way? Maybe a replacement unit?

I am going to ask a refund for this if it is not soon fixed.

Hey all,

Has anyone found a fix for this?

Im having the same issue setting up a Panasonic EZ950 as a client monitor. Signal path is Resolve - UltraStudio 4K - Teranex Mini SDI to HDMI - EZ950. Teranex SDI loop to FSI CM250 looks fine.

Could this be HDMI cable related?
iMac 2017, MacOS 10.13.1, Radeon Pro 580 8 GB, 4,2GHz i7, 40GB RAM, QNAP TVS-1282T, APC Smart-UPS 3000 RM, BMD UltraStudio 4K, FSI CM250, BMD Teranex Mini SDI to HDMI 12G, Panasonic 55EZ950, DaVinci Resolve Studio 14.1.1, BMD Mini Panel
