Ultrastudio Mini Monitor to LG OLED

PostThu Mar 28, 2019 3:10 am

Hi,

Apologises if this question has been asked a thousand times before but I just bought a new LG OLED C8 as a client monitor and I'm not having any luck sending it a HDMI signal through the Ultrastudio Mini Monitor.

•Mini Monitor works perfectly fine when connected to BenQ 4k display.
•Checked HDMI cables and ports on LG OLED by connecting it to iMac and using it as a second display.

Anyone out there had the same issue and figured out a fix?

Cheers

Buy cheap HDMI splitter and insert into chain- it may solve it. BM cards are prone to issues with HDMI protocol. Many reports even on this forum.

Amazing, it worked!

The Mini Monitor now sends a signal to the LG OLED without issue.

Cheers!

Hi guys,

I have the same problem. No picture on my LG 65c8 television. The TV does say there is something connected but doesn't show the any video. I tried the El Cheap splitter and different HDMI cables. Unfortunately no results here. What kind of splitter did you use?

Problem solved. Indeed a (powered) splitter does the trick.

What kind of splitter did you get? By checking ebay all I can find are 1080p splitters. Meaning - they take 4K in, but spit out 2x1080p, which is no good for the LG OLED.

You can find 4K splitters at many commercial sites, but is this a digital rights issue, or is there some other known reason the LG OLEDs won't work with the mini monitors?

If this would be digital rights issue none of the BM cards would work, which is not the case. Some work, others don't. It's all down to flaky BM HDMI implementation. Add active splitter and problem sorted. It's clearly some signalling issue. I have not seen any other HDMI pro device which would have such a compatibility issue.

Maybe try HDMI Doctor from HDFury. You can then also set different HDR metadata.
It has to be a splitter which proviedes new EDID.

Just got a C9 myself, and experiencing the same issue with the Decklink Mini Monitor (PCIe version). Which "cheap" active HDMI splitter is everyone using that allows these cards to work with the LG?

Sorry, can't advise you, but out of self-interested curiosity, did you try Resolve's clean feed option, at least as a stopgap until you sort out the splitter?

Just an update to this:

I previously recommended this HDMI splitter, which does successfully allow the Mini Monitor video feed to show up on the LG:

However I discovered that this unit apparently does not pass audio through to the LG TV. I tested it on a CX and a C9, and could not get any sound through this box when fed by the Mini Monitor box.

I finally got everything to work by feeding the Mini Monitor SDI output to an AJA Hi5 box, then sending the RCA audio outputs of the Hi5 to my audio mixer. The HDMI output of the Hi5 then goes to the LG.

Another much cheaper device that I successfully tested was this $25 J-Tech HDMI audio extractor, which functions exactly like the AJA Hi5, except that it takes an HDMI input, instead of SDI.

That's very helpful info, Mel!
The Hi5 is a pretty expensive bandaid for something that should work out of the box.
Don't approach Resolve with your expectations from other NLEs! They are all different.

I couldn't agree more! Luckily we had a Hi5 sitting on the shelf that we haven't used in probably 8 years, so I'm glad we can put it to use again. Thankfully the J-Tech HDMI extractor works just as good as the Hi5 (albeit with no SDI input), but I'm almost less annoyed with the cost of the additional gear I had to buy just to make the original gear work, than I am with the fact that I had to buy additional gear just to make the original gear work...and didn't learn this fact until after I spent hours of annoying troubleshooting!
