HDMI unsupported signal check device output

Hi,
I have a new youview box and I want to use it with my Sony KDL-40EX700 TV using HDMI. While booting, the TV displays unsupported signal check device output for a while, then it displays YOUVIEW logo and writes Nearly Ready underneath. After a short while it again goes back to unsupported signal check device output. When I connect using video output it works. I can set the HDMI output resolution to 1080i or 720p using the analog video cable, but when I switch back I still get unsupported signal, check device output.
I have seen several people having similar problems before. Is this not resolvable?

Hi
I've got exactly the same issue, waited two weeks for the update as this was meant to fix the issue but makes absolutely no difference, I rang support and got a fob off answer "we are aware of the problem and are looking in to it"(I get the feeling as he was somewhere not in the UK! he hasn't even seen a YouView box) I myself work as a technical support engineer and my Boss wouldn't have been impressed to say the least if I ever gave that answer to any of our customers.
I get the feeling that BT/Humax expect everyone to go out and buy a new TV that might work with the HDMI issue which is stupid as I and I suspect alot of other customers left Virgin or other services to sign up to BT & YouView to save money only to be extremely dissapointed - I 'm going to give it a month if there hasn't been a firmware to finally fix the issue on HD Televisions, I'll move to Talk Talk as they use Huawei boxes

Apple TV worked until today. Message says unsupported signal check your output device. I have checked hdmi cable with another device and it's fine. Put on a different tv and same message. Went out yesterday and bought a new Apple TV and same problem.

Which TV do you have.
You may wish to try the following:
Press and hold the menu and the up button simultaneously on the remote for six seconds, the Apple TV should then begin to cycle through the various resolutions available to it at 20 second intervals.. If you see a picture appear up on your screen, use the remote to scroll down to the OK option and select it.

Mac Mini HDMI - HDMI TV: Unsupported Signal

I have had my Mac Mini connected to a Toshiba TV HDMI-HDMI for many years without a problem.
I recently purchased a Sony Bravia TV and connected my Mac Mini to this using the same HDMI cable
Initially I had no problems although the resolution was not as clear as I would have liked
I tried to change the resolution using the Mac Mini display properties settings
Shortly afterwards the screen went blank and the Sony Bravia displayed an error message saying "Unsupported Signal - Please Check Device Output"
Oddly, when I restart the computer the screen appears to display fine but within a few seconds the screen goes black again with the same error message displayed
I have been on the forums and have tried all sorts including restarting the mac in safe mode but to no effect (it works again briefly only to go black again)
I have also connected it back to my old tv to change the resolution and refresh rates - I have tried all of these one by one and reconnected to my new tv only to experience the same problem.
Please help!

New here. I've just purchased 2 of the new mac minis, and 2 new LG 32" 1080p hdtvs (32LD450) for displays. They are for my new computer room for Christmas for my wife and I. But, with Best Buy's 14 day exchange policy, I hooked both of them up to see if the resolution was good, and too make sure both minis worked right. I went with the hdmi to hdmi setup, and when I turned on the minis and tvs, the page size was smaller than the screen size. I went into the preferences/display settings and 1080p was recognized. I kept this setting, and 'under scan' setting was available. I messed with that a little, but could not get it perfect. Then, I pointed my cursor over the bottom right corner drag and pull tab, and adjusted the page to full screen. The page size and resolution is perfect now. One thing, though... It seemed that whenever I switched to a different app that several times I had to adjust by the bottom right corner page pull tab to get those page sizes perfect also. But after I adjusted it one time, it was set every time when I went to that app again. I'm pretty sure that everyone who has had the page size/fitting screen issue has tried the page pull tab, but this seemed to work for me.

connect it to a tv which support full hd and go into the settings and lower the resolution as much as possible and then connect it with your tv once more

Hi! I purchased my ATV in Miami, but I live in Argentina. I have not been able to get the device running on any TVs. When I plug it in, it briefly shows the apple logo, then a sign saying no signal, check power cords and power source or sthg like that.

Hi!
I purchased my AppleTV in Miami, but I live in Argentina.
I have not been able to get my device running correctly, and altough I've read tons of things online, I still have no solution to my problem.
Here's the thing: after everything's plugged in and ON, I see the Apple logo briefly, then the TV displays a sign that says no signal, check pwoer cords and power source.
But everything is plugged in and connected properly, otherwise, I doubt I'd be seeing the apple logo, right?
I tried changing the HDMI cable, reversing the ends, switching ports, hard resetting the ATV, and trying a different TV. No luck.
I read there is some issue with Samsung TVs, and most LED and LCD tvs down here are Samsung.
On the other hand, I cannot return it or exchange it, since I bought it in the states.
Oh! One of the tvs I tried it on displays a little sign that reads "connected at 1280x720 @60hz", and only THEN, goes to the "no signal" sign.
Please!!! I am being driven up the walls here.... HELP!!

Try this:
Change the Apple TV resolution:
Press and hold the Menu and Up button on your Apple Remote for six seconds.
The Apple TV will automatically cycle to the next resolution at approximately 20 second intervals.
Press Play on the Apple Remote to keep the current resolution or Select to manually cycle to the next resolution.

KDL26M4000 HDMI no signal

For six months plus, each time I turn on my Sony TV, no picture. Message on screen: HDMI No signal.
When I reconnect the HDMI cable, the picture is very good. Same problem when switching to HDMI2 with Sony remote, setting, to designate port. Two calls 7/13/2015 to Sony Customer Service yielded no solution; advised to check connection. What instrument can I purchase to test HDMI cable without buying another HDMI cable and not needing. Called AT&T when I had U-verse and DirecTV which is now used. No solution offered. Post under Picture & Sound? Not a sound issue. TV manufactured Sep 2008. Any suggestions?

Thanks DaveJ. Thanks and ref your advice "Try a different device that can receive an HDMI video signal using the same HDMI Cable (e.g. TV). A local tv repair shop (Deal TV Service) tested my Sony TV and HDMI cable and advised "working just fine". I don't seem to have another device to test other than my Panasonic DVD recorder which has component cables going to TV. DirecTV shipped me new HDMI cable and component cables 7/29/2015 which I connected but have same problem of no picture with screen message "HDMI No Signal". I've tried HDMI 1 and 2 on TV using Sony remoted control to specify port. DirecTV advised 7/30/2015 they will ship another main black box. When I had AT&T U-verse priior to 3/30/2015 I had same problem. Each time I reseat HDMI cable, there is a delay and a perfect TV picture appears. A real mystery. Could problem be Panasonic DVD player recorder? How to test further including cables? My TV and DVD player recorder are way out of warranty but wish I could talk with Sony knowledgeable tech support but only can get customer service. Looking for more indepth resources. Signal level issue(s) ? 7/31/2015.

Brand New ATV3 - No HDMI video signal.

Brand New (2013) ATV3 - No HDMI video signal when plugging it in to my TV (Toshiba 52" LED).
Ive tried 3 different HDMI cables in 3 different HDMI inputs in various configurations. Still no video.
Ive tried power cycling ATV and my TV, and changing resolutions using the Apple remote - Still nothing.
Ive seen serveral forums offering many but unhelpful options.
Yes, my TV is set to the same HDMI input as the HDMI cable is plugged into.
Please help?

You tried difference HDMI cables, different HDMI ports, cycled the ATV, confirmed optical audio output works. Do you have another HDTV to plug in and test? If ATV video fails to appear in this case, I would say that this would confirm the Apple TV HDMI output is broken given the extensive troubleshooting you have already performed. In my opinion, this would completely isolate the diagnosis as ATV malfunction. Did you purchase it via Apple or Third party? Apple will replace the device within 14 days no questions asked, or service it within one year. If third party, contact them regarding your coverage.
How long is my Apple TV covered by Apple’s warranty?
Apple's Limited Warranty for Apple TV covers your Apple TV for one year. Warranty service for eligible repairs is available at no charge for twelve months from the date of original retail purchase ("date of purchase").

Sudden unsupported signal with Chromecast

While watching a show from Netflix, streaming from my nexus 4, 4.4.4 to our TV, a 42RV530U, the tv casting screen suddenly just has my TVs message "unsupported video signal". If I unplug Chromecast from the HDMI port on the back of the TV, it changes to "no signal", so it appears my TV recognizes there is a device there, but out of nowhere, doesn't recognize it?? We've been using this system for months!
I tried switching it to a different HDMI port and changing the input, which works properly with our other devices like Xbox, so I know it's not a problem with the port. I tried the Xbox on all ports/inputs and they're all fine, and just once I was able to get the Chromecast home screen back and stream Netflix long enough for one episode via a different HDMI port, but then it did the same "unsupported signal" thing, and now no matter what port/input I'm on, it won't register. The Netflix app still says it's playing and connected to Chromecast however, so I feel it's something to do with the TV and not Chromecast.
I did troubleshoot all the steps, finally ending with holding the button on Chromecast until it reset. Attempted to set it up again, but I cannot see the code on the screen. Just the same TV message, "unsupported signal".
Why would it support it just fine, and then suddenly stop, and now the TV doesn't recognize it at all??

I found the problem. Somehow, something happened to the kernel image and corrupted it. On a whim I re-installed the package, getting 4.0.1-1 again and after that the system boots fine again.
No idea what happened to it, there were no crash events or bad dismounts etc. that I know of. I guess Windows might have done something.
Thanks!

Generated Pulse waveform is distorted when I deliver the signal to the output port in the DAQmx

Problem: Generated Pulse waveform is distorted when I deliver the signal to the output port in the DAQmx.
Environment: Windows XP sp3 (32bit), Visual Studio 2010 sp1, NI-Measurement Studio 2010
Device: NI - DAQmx PCI 6251
 Analog Input: 1.00MS/s multi-channel (aggregate)
 Analog Output: 2 Channel 2.00MS/s
Reference Example: AO_ContGenVoltageWfm_IntClk / AI_ContAcqVoltageSamples_IntClk
Generated Pulse:
1) AO0 = Square Waveform /0-5V / 8KHz / 0.5㎲/sample / sample 50% Duty
2) AO1 = Square Waveform /0-5V / 8KHz / 0.5㎲/sample / (Reverse Image)
Description: I’d like to deliver the waveform stream satisfied with specified constraints to the 2 channel output port in the DAQmx. To verify accuracy of the generated waveform, I did an electrical wiring from the Analog output channel (2 channels) to the Analog Input channel (2 channels) in DAQmx. As a result of this experiment, I could get a result which has signal distortion. Since the waveform has to satisfy with both high frequency (8KHz) and very short moment interval time (△t = 0.5㎲/sample) between samples, I cannot handle some parameters of the function in the referenced VC++ example. Following formulas shows an approach to deliver the generate pulse waveform to output port satisfied with constraints.
Analog Output Channel
Frequency = 8,000 cycles/sec (constraint)
Sample per Buffer = 2,000,000 = 2*106 samples/buffer
Cycles per Buffer = 80,000 cycles/buffer
Sample per Channel = 1,000,000 = 1*106 samples/channel
 Sample Rate = Frequency * (Sample per Buffer / Cycle per Buffer)
                          = 8,000 * (2*106 / 80,000) = 2*106 samples / sec
 △t = 1 sec / 2*106 samples / sec
           = 0.5 * 10-6 sec/sample (constraint)
 Buffer Cycle = Sample Rate / Sample per Channel
                          = (2*106 samples / sec) / (1*106 samples/channel)
                          = 2 channel / sec
Analog Input Channel
Sample per Channel = 1,000,000 = 1*106 samples/channel
 Sample Rate = 1 MS/s * (2 Channel) = 5 * 105 Samples / Sec
Program Code
AO_ContGenVoltageWfm_IntClk / AI_ContAcqVoltageSamples_IntClk (VC++ Example)
Result: The proposed approach was implemented in the experiment environment (VS2010, MStudio2010). As shown in Figure 1, we could get the unsatisfied result. Although I intended to make a ‘square’ pulse wave, the result looks like ‘trapezoid’ pulse wave (Figure.1). However, there is other result which was undertaken with different parameter condition. It looks like the square shape not the trapezoid shape.
Please let me know what the conditions make the problem of signal distortion. (AO0 = Green line / AO1 = Red line)
[Figure. 1] Frequency 8000 Hz / Cycle per Buffer = 8000 Result
[Figure. 2] Frequency 1000 Hz / Cycle per Buffer = 1000 Result
Questions: Please let me know following questions.
1) Is it possible to deliver the generated pulse wave satisfied with constraints (f= 8KHz), △t = 0.5㎲/sample) to the output port without distortion using PXI 6251?
(Is it possible to solve the problem, if I use the LabView or MAX?)
2) Are there some mistakes in the proposed approach? (H/W or S/W program)
3) What is the meaning of the Cycle per Buffer?, It could effect to the result?

Hi Brett Burger,
Thanks for your reply. For your information, I have set the sampling rate as 10000 as for the sound format, I have set the bits per sample as 16 bit, the rate as 11025 and the sound quality as mono. I tried using your method by changing the sampling rate as 8K but still my program encounter the same problem.
I wish to also create a button that is able to generate a preformatted report that contains VI documentation, data the VI returns, and report properties, such as the author, company, and number of pages only when I click on the button.  I have created this in my program, but I am not sure why is it not working. Can you help troubleshoot my program. Or do you have any samples to provide me. Hope to hear from you soon.
Many thanks.
Regards,

HT204400 I am getting a message of an unsupported signal when installing my Apple TV

I have a new Apple TV. I hooked it up to my Sony Bravia with an HDMI cable and am getting a message from the TV of an unsupported signal.

Is your store location correct.

Apple TV 2 - HDMI CEC Signal?

Does anybody know whether Apple TV 2 sends a HDMI CEC Signal?
I have a Neet 3-port auto HDMI switcher so that several HDMI sources can be used on one TV HDMI port. It switches to a device when you turn a device on. It uses the HDMI CEC signal. It is not working with the Apple TV 2.
Neet support have been very good and have offered me to upgrade to the remote controlled version for free, but before I take them up on it I would like to know if the Apple TV 2 is sending the signal or not so I know whether the unit is working or not.

So cynical...yet probably so true
I must remember to ditch all my other media devices now I'm in ATV land and dedicate my TV to the little black marvel...
...but back in the real world, impressed as I am with the HD movie streaming its too pricey for me to seriously consider it being the only thing I want hooked up to my TV. Not to mention the life-confirming requirement for Sky Sports on my HD box. So the CEC signal, or lack thereof, is a mark off IMHO. Not a perfect 10. I will now have to get my lazy butt off the sofa and manually change the auto-switching device thing with the ever-so old fashioned manual switch button. A neat step up from changing cables but still off the sofa. Or try not to lose yet another remote (courtesy of the wonderful customer service of Neet). Before realising I have to get of the sofa anyway to manually change the optical cable switch to get the wonderful surround sound. Or buy another TV with even more HDMI inputs and a home cinema system with even more optical inputs.
Life, eh?

Unsupported Signal - AppleTV

I have a Sony Bravia KDL-46EX500. I've connected my brand new Apple TV to it. I turn it on, see the Apple logo for a few seconds, and then get the mention "Unsupported signal". The HDMI cable is working fine (tried it with other items and it works fine). I've updated my Apple TV via iTunes, but the problem persists. Help please!

Welcome to the Apple Community.
Leo you have another TV you can try it with. Are you connecting directly to the TV or going through a receiver.

"Check Input Output Prompt" when trying record master.

Been going through the ringer on Print to Video w Final Cut Express 4 to my Canon XHA1 1080i. Finally got rid of the "Transcoding to HDV" prompt after converting file to QuickTime and changing my sequence settings. My VCR signal set up is correct (checked w Canon) and my firewire cable is fine. Still receiving "Check Input Output" when I go to record on camera. Any suggestions would be greatly appreciated!

It's been seven (7) days since I filed a suport case, no reply from WD...The way this is going the drive will soon end up at a recycling station after it has been smashed with a hammer. :-(Which means I will be in the market for a non-WD NAS very soon, they don't seem to support their customers very well. Buggy firmware, ages between fixes, inability to actually upgrade, and lack of support. Disappointed to say the least.
