When I connect both the Ronin-S (via USB-C for tethered control of DC-GH5 via the Ronin-S) AND an Atomos Shogun Inferno HDMI recorder via the full size HDMI port on the GH5, the GH5 screen and viewfinder switch off and cannot be switched back on. This means that there is no way to view any information about the camera status (unless you choose to turn on the option in the GH5 to output camera infomration to the external HDMI display, but if you do that then of course you can't use that as a clean video feed).
The outcome of this is that the Ronin-S cannot be used with the GH5 and an Atomos / HDMI recorder simultaneously.

Unplugging either the Atomos HDMI recorder or the Ronin-S restores usual functionality on the GH5.

Ronin-S firmware: 1.3.0.20
DC-GH5 Firmware: 2.3

I have spoken with Panasonic engineers here in Japan who say they were unaware of this bug and are now investigating.

This is a known issue on the Ronin-S Facebook group, other users have reported the same thing on various monitors, though it's less of an issue because we're not trying to record the output like you are.

My current theory is that the GH5s is sending out a video feed through the USB port like it would connected to a PC except the Ronin-S has nowhere to display it and this is disabling the back screen on the camera. I'm guessing this is more of an issue with "Tether pc" mode on the GH5s than it is with the Ronin-s. I haven't actually tried tethering the GH5s to an actual pc yet, so I honestly don't know if it disables the back screen.

For you, I can imagine this is a huge issue as you stated you lost all info display as you're trying to record a clean out. I just have the info displayed as I'm only using the monitor for focus and framing reference. If there's an incoming update for the GH5s that fixes this that would be amazing, but I wanted to respond to let you know others are experiencing the same thing and so far no solution has been identified.

I have this issue too, although I’m just using an external monitor rather than recording so I can use the info display instead, but I’d rather use the camera LCD for the info display and monitor for the actual output.
I suspect it’s a tether issue with the camera too.

Hi there, thanks for reaching us. This happens due to the Panasonic's design, the same problem will also appear when using Panasonic's control software. Our engineers are keeping working with Panasonic to see whether this can be optimized. Appreciate your attention and patience.

Panasonic engineers have just phoned me with an update.

As Susan rightly says,  the problem is that the GH5 / GH5s only has 2 video channels, and when connecting the Ronin-s (remote tether) this counts as one channel, and an external recorder will count as the second channel - so the internal screen switches off as there are no more video channels available.

The same occurs if you use the remote app for the GH5 and a monitor, of gimbal.
This is not something that can be fixed in firmware and so is just an inherent limitation of the camera.

Until the day before yesterday, I could use the Ronin-S tethered, pulling focus, and have the live view on both the internal display and the external HDMI monitor. What changed yesterday? I upgraded the GH5's firmware from 1.2 to 1.3. So the problem clearly came with the update.

Im confused.  Even without the Ronin as part of the system, if I plug an external monitor into my GH5s, the camera monitor goes black.  This is how my GH5s works even without the Ronin in the mix.  sorry if I am missing something here, but.... am I missing something here?

I too experience this issue. When the GH5 is connected to the Atomos Ninja V (HDMI) and the Ronin-S (USB-C) the LCD screen on the camera goes black and no longer displays information.

Since there is no solution yet to have both plugged in, I'm going to unplug the USB-C tether. I'd rather have the monitor to see (and record). This means having to focus & hit record on the camera itself, which isn't ideal, but not a deal breaker. Unless I'm losing some other functionality by disconnecting the Ronin?

Please let me know if I'm missing something. Thanks.

I have a GH5 and GH5S. I recently updated the firmware on the GH5S to the latest version (2.3) and now it exhibits this behaviour (LCD goes off when USB-C plugged in and HDMI plugged in). My GH5, with the older 2.1 firmware on it keeps the LCD on... I haven't tried downgrading the firmware yet, not sure if it is possible.

Firmware versions not entirely accurate ^ but you get the idea, the new firmware made a "fix" to the HDMI output and that seems to have caused this problem.

Any further news on this issue?  I'm trying to use my GH5 with Atomos Ninja V and Ronin-S and facing the same issue. Screen goes blank on the camera when I plug in the USB.  Thanks

I just discovered this issue today, having not used my GH5s and Ronin together since the latest GH5 series firmware upgrade.  

Discovered it in the field, on a shoot.  I can absolutely verify that prior to the latest Panasonic firmware version you could monitor HMDI while the Ronin-s is connected to the GH5s AND be able to view the LCD/viewfinder at the same time.

Hi,

Same issue here with my GH5s and the Ronin S.

I've updated both systems.

Please who should we complain to fix it?

Panasonic or Dji?...

By the way, could someone from Dji support tell us where we stand on this issue?

Is an update planned soon?

Regards.

So if we know that Firmware 2.1 worked, and that firmware 2.3/2.4 doesn't, then we know it's something to do with how the GH5 is recognizing the tether.  

DJI NEEDS to work with Panasonic on this, it's basically reducing the usefulness of the Ronin-S for the largest swath of customers, and means that these customers WON'T buy the next Ronin because it won't work with their gear.

Panasonic users are not even close to the largest group of Ronin-S customers.  Panasonic makes up a very small percentage of the professional videography market.  This will most likely never be addressed by either DJI or Panasonic.  The Ronin S's incompatibility with my GH5 made it a no brainer to return it shortly after I bought it this summer.  I am currently awaiting a Moza Air 2, and have higher expectations for the product in general after extensive research.  I experienced too many issues with the Ronin-S, and received nothing but lip service from DJI.  

I have that same problem. Did you find a solution?

Has there been a fix yet for this issue?

I'm with the gh5s and after the update the problem still exists. The camera's screen goes blank when connected to ronin and the ninga v..

DJI Susan Posted at 1-2 03:31
Sorry for the late response. This issue has been optimized, please kindly update to the latest firmware and see whether it works well.

This problem has not been resolved as of the latest firmware.

Hi SwampFighter, we have tested at our end, but the issue does not appear. Could you offer the below information, we'll double check and locate the exact status, thank you!
1. The Firmware version of the Ronin S;
2. The Firmware version of the camera;
3. Which type of monitor do you use?
4. Operation video when the issue appears.

Hi Susan,

1. Latest
2. 1.2
3. Atomos ninga v
4. Are you asking me to make a video that shows the problem?
Basically, the screen goes black in the camera when it connected to the ronin with usb-c, right at the second I connect the ninga v.

I have the same exact problem. Does anyone know if it has been fixed?

Hi there, I just got an update from our engineers that the balck screen appears due to the rules defined by Panasonic. Using the MCC-C to connect the camera and PC, also connect an HDMI cable for the external monitor to the GH5, the same phenomenon will appear when connecting a PC and then plugging in HDMI. Sorry about this.

So how come it worked in previous firmware?

Do you understand it limits our functionality when using the ronin to the point not being able to use it with a screen at all? If I can't see the parameters of the camera, I can't trust it while recording...

Please encourage your engineers to make another effort to find a solution. It worked before, no reason it would not work again.

Its a quite good question how it is possible that this could work in last firmware and is not working in current.
Can this be proven by others??

Are you sure? You can downgrade the Ronin S to verify.

Not for me. People here stated it worked for them.
I think they meant for camera firmware

May I know what's the version number of the previous firmware do you refer to? We'll double check with the team.

There arn't that many Firmware versions for the panasonic GH5.  The current version is 2.4.  2.3 was in May.  2.1 was in 2017.

This video seems to show the Ronin-S, the GH5, and a Ninja recorder all being used in concert.  Forward to 0:41

Was it allready mentioned that

- the focus wheel and record button stop to work -
- the autofocus fails too, it gets to Backfocus and doesn't react -
It happens after a while (2-7 minutes or something) after connecting of the 3 devices? The LED of the focus wheel blinks red.

Then I unplugg any of cables (DJI/USB-C or atomos/HDMI) from the GH5s and plug it in again and then it starts to work again.
But only for a while.

Hi SwampFighter, we've checked at our end again, the issue will appear when connected with the camera control cable. The camera will enter PC mode, and the screen will be black when connected with the monitor. It matches with the conclusion of 29#.

Hi Suzan,
So if I understand you, you say this is what we get and we need to get used to it..?
I thought to maybe get the external motor and give up on the internal focus control but then I remembered  that i will loose also the control over the record button and that is not an option to me.
Also not an option to give up on an external screen due to the limited size of the gh5s screen.
So I'm stuck with this setup according to what you say.
This is so sad... I think I'll need to get apart from your beautiful device..

I have the same problem when recording with Ninja V. This makes the Ronin S practically unusable.

Please provide a fix for this.
