Atem Mini - HDMI input/output issues

I have run into an issue connecting my Atem Mini HDMI output to an LG 4K TV.

The Atem Mini HDMI output displays correctly on the TV only when showing Black, Color Bars and Color Mattes. When selected to show one of the HDMI inputs the signal drops out and the TV goes into "No signal" mode. If I Fade To Black the connection restarts to show a black video image.

- The Atem Mini does not have this issue on other displays I have tested.
- I tested a second Atem Mini with this LG TV and had the same specific issues.
- the problem was the same with all HDMI inputs on the Atem Mini, 1-4
- This LG TV has had no issues connecting to a variety of other HDMI signals such as camera, Apple TV, DVD, etc.

Any thoughts on what is causing this problem or how to fix it are appreciated. Thanks

I have the exact same Problem but with a Samsung TV
Did you get a solution yet?

I seem to have the same problem here. I get audio through the HDMI and I'm able to turn that on however video only works when I send Input 1 straight to the output. Not when I'm using preview/program as the output.
Could this be an HDCP issue?

I have just managed to solve the exact same problem I was having by putting a cheap HDMI splitter in between the Atem mini and the LG TV to remove any HDCP misunderstandings between the TV and the mixer

Between the output of an ATEM and the input of a connected device there cannot be an HDCP problem. HDCP problems can only crop up with devices whose outputs are connected to an input on the ATEM.

If that splitter "solved" your problem that's great, but it is for some reason other than HDCP.

If its not HDCP then I would really like to find out what the exact problem is that makes you able to direct your inputs straight to the TV with the Atem software but as soon as you try to send an input or a still the TV says 'no input'
Fixed colours and colour bars worked perfectly fine on the TV it was only when trying to put content from one of the inputs on screen that it gave the issue.

Is the splitter between the ATEM and the TV, or between the ATEM and the source (input)?

Also, is the source on input 1 and the direct/low-latency output mode being used, or is this impacting other inputs as well?

Splitter is between the Atem and the TV.

I've used all 4 inputs with different devices (macbook, windows laptop, cheap consumer dvd player) and when using the output in programmer or preview mode in any resolution and framerate available the problem occured.
When routing the output as any of those inputs (bypassing the mixer) the problem dissapeared.
Using the exact same configuration with a macbook on input 1 sending 1080P50 and an MSI windows10 laptop sending 1080p50 but then an HDMI splitter in between the TV and the Atem output the TV recognised signal from those inputs and everything worked normal. The HDMI splitter was advertised as HDCP bypass to be used to connect a PS3 to a new TV.

Interesting. Then it might actually be HDCP if the ATEM is simply passing the signal through unchanged. I would expect the USB-C out to also fail to display the image in this case.

That is particularly interesting as newer TVs most likely support HDCP, and even more interesting because defeating HDCP could potentially land them in legal trouble...

I have exactly the same problem with my LG 4K tv which was first out two years ago! Any help will be very welcome as I really need to get this up and running as a QLab webcam input for a show in 2 weeks! I don’t want to use my emergency backup of old cameras connected to old projectors!

Going to try very old Samsung tomorrow and other monitors. Will post results!

Only got the Atem mini today and was last one on shelf from 4th UK stockist I tried so hope it’s a teething problem not a faulty switcher.. USBC is fine but I need hdmi too

Connecting an HDMI splitter between the mixer and the LG TV worked for me as well. Since the ATEM Mini outputs non-input video (black/color bars) it does seem like it must be the HDCP blocking the connection.

Thank god im not the only one having this issue ive had a support call open with Blackmagic support since 3rd February!

I have the issue on both my 4ktv's one being an LG49sk8000 and also a newer Hisense hb557100k TV.
After weeks of back and forth with BMD support i sent my unit back for testing at their lab and have been sent a replacement unit which has the exact same issue.

Interestingly by fluke while testing the new unit i plugged my Sony camcorder in as an input and had the exposure set too low giving a dark image. While in this state the TV kept signal from the ATEM mini. As soon as i turned the exposure up the signal was lost!

Further testing reproduced the same issue having low exposure with a dark (black level ) image keeps the signal, while expsore is low if I point the camera at the ATEM Mini with its lights it stutters and again turning up exposer slightly the signal cuts out.

also during testing

When set to picture in picture with the mini picture the active HDMI source sometimes you get a distorted mini image other times a black screen but active signal.
Cutting to a still from MP1 source it goes to black screen
When cutting to colour bars it goes to black screen
When Picture in picture/key er does work if you change some of the settings say add a shadow border it cuts to a black screen.

And like others going though a cheap splitter my AVR etc the image is fine and alos fine on my PC monitors.

Cant see it being a HDCP issue it seems to be when a bright image or anything above black level is disaplyed it cuts the signal the ATEM Mini must be sending non-complaint HDMI signals out to the TV and the TV does not accpet them. Cheap splitters and monitors must be more tolerant to this.

Ive fed this back to BMD Support will wait and see what they come back with.

Hi all, any more luck with this? I’ve had same issue (although I haven’t tried black screen - just no signal full stop.) it was actually working for me when I first got the unit. But a few days later it stopped. I’m pretty new to all this and wondered if I’d fried something due tot leaving it on overnight - I noticed it runs quite hot?

The only time I seems to get a signal was when I found a setting in the changing the Res, FPS and refresh rate... one of the settings caused the screen to temporarily pick up a signal, but then went again...

Could this be a design flaw in all units?

I dont get output on my ATEM mini. It was nice on the day one, now i see flickering screen.

Same Issue. LG 4K TV. Works with Camera 1 direct output. All other modes - No signal. Any hope blackmagic will solve that?

Well ive just updated my ATEM Mini to the new 8.2 version of the software and still no luck with getting a proper output to either of my 4K TV (LG/Hisense). I have made another video demonstrating the issues and this time showing the exposer thing with the camera as they wanted to see that.
Hopefully they will get this sorted.
Heres the video in case anyone wants to see the issue in action

Mine is a bit more complicated. On my output, I have 1 Acer projector, 1 LG projector, 3 Hisense TVs, 3 LG TVs all picking signals from one HDMI splitter. All signals are flickering and when I change the resolution setting on the software, some will show while other will say bad signal format. It’s a hall

Me thinks the splitter is the issue here. You can not take a single signal, and just split in into several outputs and expect a full output on each device connection. The more you hook up the, greater the signal loss. If you need to feed several devices from one output, you need a device that can take the input, re-clock and redistribute the signal without loss (like a distribution amp,). HDMI is very sensitive to signal loss over long cable runs or the use of multiple passive splitters.
Cheers

I hope there will be an update soon enough to fix all this fuzz because as it is at the moment, the device is just useless for me

I just received my Atem Mini Pro. Same issue here with my Samsung 4K TV.
I actually see the multi view grid with all the information and black camera preview windows when nothing is plugged to Atem Mini pro's inputs!!

As soon as I connect any of my cameras to the Atem Mini Pro's HDMI inputs, my TV tells me there's no signal.
I even tried with a cheap bi-directional switcher but no luck. I guess it should be a splitter instead of a switcher, but I don't have one at hand. Also it seems weird having to use extra splitters to get the signal to a standard TV. Any comments from BMD? Will there be a fix for this?

What is the frame rate of the camera connected to HDMI input 1 on the ATEM Mini? Connect this camera directly to your TV and see if it send s signal to the monitor. The ATEM Mini will set its output frame rate based on HDMI input 1 device setting.

All my cameras are set to output 1080p. I tried with different rates, 24,25,30,50 and 60fps all work fine with the cameras connected directly to my TV. If I connect them through the ATEM Mini Pro, I get the 'no signal'-message and the multi view grid disappears, eventhough it's displayed fine when no cameras are connected to ATEM Mini Pro.

Everything works fine with my small 5" monitor. It just would have been so convenient to use a large TV when available, and I really don't understand why it doesn't work.

OK, when connected directly your TV is doing a handshake with your camera to set a matching resolution, it appears the TV monitor is unable to get a complete handshake with the ATEM Mini Pro.
Others here have reported a similar issue with some TV monitors.
Cheers

Following on from Denny's comments. If it is a handshake (EDID) issue a 'Dr HDMI' may help as it sits in between the two devices and allows you to choose the EDID presented. Used to be used a lot with GoPros

My ATEM Mini Pro arrived yesterday and is exhibiting the same issue. I've plugged my 55" LG OLED TV in to the HDMI Output and it just won't see it at all. Plugged in my Atomos Shinobi 5" monitor and it displays the M/V interface straight away. It'll do for now, but I want it on the big TV, not a tiny little screen. Fingers crossed BMD fix this issue soon.

Have you tried this on a shorter hdmi cable?

It wouldn't surprise me if it's the length being on the limit for dropouts.

You need to set the ATEM Mini to a resolution that the TV monitor will accept, or get a converter like Dr. HDMI to get a proper handshake connection. Try setting the Mini to 1080p30/29.97

I'm new to this and I'll be getting my ATEM Mini Pro next week for a broadcast the following week and I ordered an LG 27" TV.
Do you think I could bypass these issues if I use a higher quality broadcast monitor? I read earlier in these posts that It seemed to work on a smaller monitor that wasn't a TV. But I too want it on a bigger screen. Any suggestions on that would be helpful. Thanks all.

Thanks Denny, but I set it to 25fps and it’s made no difference.

See Greg’s comment below, I think he nailed the issue you are having.
Cheers

OOTB, the mini format is set to Auto. When nothing is plugged in it defaults to 1080p59.94. Thats what it's going to handshake with your TV. If you plug in a 1080p30 into input one, the Mini will change it's format and output. Now the TV is expecting 59.94 and getting 30 - I'm not surprised if the picture goes away.

Try setting your Mini to one of the static formats (anything except Auto), disconnect/reconnect your TV and see if this makes a difference. Alternatively, connect and turn on all your input sources into the Mini before you connect/turn on your TV. This way the TV will sync to a format that will stay the same...

I got the same issue. Raported it to BMD, even got my unit replaced via RMA. Still the same.

I got multiview when there is no HDMI input, when I input anything via HDMI (2 cameras tested and computer) I got "no signal" on my BENQ SW270W. Although it works fine with my 8 years old Plasma TV (Panasonic).

I got myself Atomos Ninja V (haven't planned to buy it), and signal looped via Atomos works fine on my BENQ now. Not the best solution, cause it's expensive and more clunky.

Tested serveral HDMI cables, 2 cameras, computer as input. USB output is finem but HDMI out does not work with BENQ (and also NEC E231W - this one never works but it's via HDMI to DVI converter).

Solution by MambaFiber.com does no work for me. Tested all modes, reconnected display to ATEM. Still the same.

Yeah, not great is it. Someone previously mentioned it was a YUV vs RGB output issue. If that is the case, why can’t BMD make it so you can choose which it outputs, like you can on the Ultrastudio 4K Mini.

You might want to try today's update 8.2.2:

What's new in ATEM 8.2.2
Adds frame rate conversion to HDMI out.
Improved graphics quality in multiview display.

Hey guys I ran into this issue myself yesterday and thought I would throw my hat in the ring. I actually did not know there was an issue initially because I was looping my HDMI output through a small HD502 monitor and the TV was receiving the secondary feed. The only small issue is I am receiving no audio to the TV and so I tried to direct connection to see if that would resolve the problem and in fact it wouldn't even show up which led me to this forum. I'm back to looping through the small HD but it would be so great to have sound hitting the TV and bouncing back or be a little delayed via Bluetooth for monitoring the mix. I watch with interest to see if anyone can provide a definitive solution.

There is a FW update out to correct HDMI output connection issues.
Cheers

got the latest software update, HDMI output not working out to a TV monitor,

the only thing that works is camera direct since its bypassing,
is there a firmware update? any fixes yet?

this solved the issue!


the picture didn't show lol

I got the BMD MicroConverter, used the HDMI in and out

Tried latest firmware 8.2.2 and still exact same issues as before.
really wish they would fix this!

I have the same problem. I think I have tried most of these things. My Firmware is up to date. I can use it with the streaming view on my computer but obviously that isn't ideal. Any other solutions. Thanks

I hate to say it but, me too. No HDMI output and then a "no signal" on my 4k Samsung.
The USB-C output does seem to be working on a connected Mac computer though.
Tried different HDMI cables, different monitor, and so on.
Even unplugged the USB-C to see if it could only do one at a time--but no difference.
That's a shame. Just got mine today, so back it goes early next week unless we can find something to make it work.

I guys,

I got the same/similar problem.
On my monitor the Multiview, Program doesn't show, but the Camera Direct. So I mesuere the output.
I found out, it's related to the Frequenz. First I got 25Hz. Doesn't work, on 50Hz an d 60Hz it run perfekt.

So you have to switch the Output to 50p or 60p. Try that, on my case it was the solution.

I'm having the same with ATEM mini pro. Colors, bars and Camera 1 Direct are ok, nothing else isn't.
TV says No signal, Video Assist also.

I had a chance to test HDMI OUT with Epiphan Capture Tool and DVI 2 USB 3.0.
The Capture Tool was able to show multiview from HDMI OUT of ATEM mini pro just right.
The Tool shows some parameters and it was receiving 1920 x 1080 @ 60,2Hz when ATEM mini pro is set 1080p60.

I'm not that experienced with video, but I think that HDMI OUT is working just fine as a pipeline,
but there is something about the format it tries to output.

I have to admit that this is really annoying issue and I hope the solution is coming shortly.

I had no issues running 1080p29.97 on a ATEM Mini to output on the HDMI multiview, program and camera views to a Dell computer monitor that has an HDMI input. It worked great, at several resolutions, including 1080p59.94. It also worked with a SmallHD Focus monitor.
Cheers

I have experienced this exact same issue with the ATEM Mini Pro and a GeChic 1305H Mobile Monitor. The monitor doesn't connect when the ATEM HDMI output is set at Multiview (and all other options except Camera 1 Direct) but when I select the 'Camera 1 Direct' option, the monitor and the ATEM connect.

After viewing this thread, I put an HDMI splitter between the ATEM and the monitor and everything including Multiview work as expected.

A new thought for this discussion, the HDMI splitter I used has a switch that can be set to 'EDID STD' or 'EDID TV'. Everything works when 'EDID TV' is selected and it goes back to the original issue when 'EDID STD' is selected.

Hopefully this information will help BM engineers to come up with a firmware solution to resolve this issue?

I connected the ATEM mini pro to my desktop PCs display, Samsung U32H850, and multiview worked just fine.
This makes no sense to me.
I'd imagine that Video Assist should be the one that works flawlessly.

I did a test with my old Samsung TV.
It was just plug'n'play type of case, multiview worked immediately when I plugged in the HDMI cable.

Same issue with my atem mini pro / LG OLED 4K TV

I have installed the last software update. Behavior is different now:

I do not have any input at all now (except camera 1 input), no other hmi output even with all hdmi input turned off. (Before updating: multiscreen preview interface with black screens when all hdmi input turned off, and « no signal » with hdmi input).

It’s a serious issue. Blackmagic has to communicate about it (situation, reason, list / specification of compatible / incompatible tv monitors, workarounds etc).

Some news?

Hi Koen, I confirm this resolves our issue.
Thanks again for your help and time, here and through mp.

I'm having the same issues, attempting to run HDMI output to a projector, while capturing program feed to PC via USB.

What we've been told by tech support here in Australia is that there is an issue with colour space - ATEM Mini/Pro is capable of YUV only and if the projector or other device doesn't take or isn't expecting it, then it won't work.

I have had to abandon use of the ATEM for this purpose but it's just a shame and seems there is no documentation about this.
