HDMI display: no signal

I am trying HDMI for the first time. I have a DVI splitter connected to the Mini and a VGA cable going to one display, which works fine. Today, I got a DVI to HDMI cable and connected it to my projector. I turned off the LCD display and turned on the projector. It said "no signal." Do I need to restart the Mac? Is there a reason that VGA works and HDMI not? The projector also has a VGA connector and that also works fine with the Mini.

I am happy to say to the problem is solved. The projector was set on "auto" for computer input. So, it should have detected that the VGA cable was no longer connected, but the HDMI cable was. It failed to do that. By forcing it to look at the HDMI input, it worked. The Mini correctly identified the projector and set the resolution correctly. Now, I just have to try the splitter and see if that will work.
Thanks for the help.

HDMI Extender/No Signal

I've had an MSI HD 7770 since 11/2012 working just fine over 2 hdmi extenders from my basement to my living room. One goes to my TV the other to a monitor.
Yesterday they stopped working.
Video card works fine when hooked to a monitor directly using just one hdmi cable.
Video card still detects both my TV and Monitor in Catalyst but both display no signal.
Xbox and Bluray player works fine over extender
Right now I removed the card and am able to use the onboard graphics card over the extender
Any ideas? Support says they will test the card using one local monitor and it will test fine that way so they will send it back to me.
Thanks for any help

Just incase anyone else has this issue I thought I'd let you know that I found a work around
I ended up getting this to work by buying one of these:
hxxp://www.ebay.com/itm/Mini-HDMI-Surge-Protector-Protection-Against-ESD-Power-Surge-5V-Power-Booster-/310823624915?pt=US_Surge_Protectors_Power_Strips&hash=item485e8820d3
It only works when I hook up a USB cable to provide extra power to the HDMI signal.
Still not sure why it worked for 2 years and quit all of a sudden.

How to read and display a signal from my a miccrontroller (MCB1700) onto labview connected via a CAN port on a PXI machine

How do you read and display a signal from my a miccrontroller (MCB1700) onto labview connected via a CAN port on a PXI machine?
I tried using a DAQ Assistant but the CAN port is not included as one of the supported physical channels even though all its drivers are upto date.
Please help..
Thanks.
Solved!
Go to Solution.

Attached herewith is a print screen of what is showing on MAX
The CAN ports are on NI PXI-8461
Hopefully that clarrifies something.

How to read and display a signal from my PIC Microcontroller onto Labview?

Hi,
I am doing a project on a Pulse Oximeter and i am trying to read and display the signal from my PIC Microcontroller on Labview? How do i go about doing it? I am using the PIC16F877 and also making use of the USART?
How do i implement and initialise the USART in PIC16? What are the steps to be taken, please guide me through the process? The link provides information regarding the USART connection, initialisting and stuff? Is it correct to use these codes in my program?Link: http://ww1.microchip.com/downloads/en/AppNotes/00774a.pdf
Also, i am using the RS232 serial interface to connect to the PC? The connector i am using is the DB9 Connector. Which template and VI can i use? Am i supposed to use the NI-DAQmx and VISA? Also, for my USART connection, i am using the MAX232 Driver which is applicable for my application as i am working with +5V. So far, i have been reading and trying out on Labview and the steps i have taken are:
1) Open a New VI and used the Instrument I/O(Read & Display) template?
2) How do i configure the Instrument I/O Assistant Express VI to read the info from my device connected to COM1?
3) I was reading the Labview Manual, 'Getting Started with Labview' and i was following the steps under Page 55, Communicating with an Instrument. Am i on the right track?
4) How do i check and make sure that the port settings of the I/O Assistant and my PIC Micro Match
Please help me out and guide me through the process. I am student at a polytechnic and i am very new to Labview and the software is used as a development tool for the project. I have a deadline to meet and i hope i can get a response as fast as possible. Your help will be kindly and greatly appreciated. I hope to hear from you guys soon.You can e-mail me all your answers at [email protected]
Thank You

Hi Ashwin,
It is a good idea to first be able to communicate with the microcontroller using some sort of serial communication software such as "HyperTerminal" or "Procomm", etc. Refer to MicroChip's recommendations on this.
Once that works, then you are ready to use LabView.
Here is a link which covers many aspects of serial communication. Link - click here
You probably received a development kit. They usually have a readily available interface. It's been a long time since I played with the PIC, but I seem to remember that you need to program the serial communication driver (as well as at least a bootloader) to get the serial communication going. The driver contains the necessary protocols so that you PC can have a machine conversation with the target (PIC).
It sounds like a fun & interesting project. Please avoid to have replies to your personal email. By having the answers posted to this thread, you will get much more support and advice.
Have fun,
JLV

Hi Ashwin,
I am not familiar with the PIC Microcontrollers, but I am assuming you mean that you have the microcontroller sending out serial data that you want to read on another computer with LabVIEW. Please let me know if this is incorrect.
What type of data is coming out of the serial port? Is it ASCII, or binary? The reason I ask this is that the serial communication in LabVIEW is done through a protocol called VISA, which uses ASCII data to send and receive. You can later convert this data into whatever form you need, but this is what it is designed to read and write.
You can check the settings such as baud rate and data bits in a configuration utility called Measurement and Automation Explorer, or MAX. When you open up the MAX interface, you can expand the Devices and Interfaces entry on the left, and then expand the Ports entry to see your serial port. When you highlight this port, select the Port Settings tab at the bottom of the window, and you can see what the current settings are, and change them if you need to. You can also set these parameters in LabVIEW using the VISA Configure Serial Port VI.
You can also test communication in MAX by right clicking on the correct port and choosing Open VISA Session. Then choose the Basic I/O light blue tab, and then go to the Read tab. When you click execute, it should read in what is coming from the serial port. This will allow you to verify that the correct information is coming in before even trying to acquire the data in the LabVIEW environment.
In LabVIEW, the best resource to use the Basic Serial Write and Read example program that ships with LabVIEW. By examining the block diagram of this program, you will be able to see the basic programming flow of serial communication in LabVIEW.
I hope this information was helpful! Please let us know if there's anything else we can help with.

HDMI display no longer detected

Soon after updating to OS X Mavericks my Dell HDMI display stopped working (the screen went into power saving mode) and isn't detected by my Late 2012 Mac Mini. Have tried reboots and disconnecting the power and HDMI cables to no effect. I can remote desktop into the Mac MIni from a PC so can still access it to try different options.
Any suggestions?

Yeah, the issue still continues for me. I thought that I had it resolved by doing a NVRAM reset, but the dreaded issue came back. I initially noticed the issue would occur much faster if I was using VirtualBox, but after updating VirtualBox the issue isn't as prevalent. I'm also able to make the issue occur much quicker if I'm running a Flash based game in the browser. When the issue has occurs and I get back into the machine remotely and open the console I can see that the Window Server has gone sideways. Related output follows:

Is garage band included on 10.6 OS and hdmi display issues?

Imac, 17 inch display, 2.0 GHz, 1GB ram two issues. Can I connect an hdmi second display (hidef tv) through the thunderbolt port and does garage band come with OS 10.6. Can't find garage band anyplace and the second display when plugged in to an aftermarket thunderbolt to hdmi adapter sees the hdmi display but won't mirror. I have a clean install of 10.6 and can't get past these two issues. Any help please.

Here's the issue. I can only get 3 meg d/l speed and that drops to as low as .5 meg at times. I can link my MacBook Pro to an hdmi hi def 1080 thru a Devi connector and all works fine. I run Netflix and the MacBook buffers the content so if the speed lags the show doesn't stop. I came across this iMac and was hoping to do the same thing. I bought an Apple TV 2 nd gen and it just stops and stalls due to no buffering. So that's not working. If I can connect the iMac to the larger Vizio with hdmi inputs, 1080 hi def I would allow the iMac to run my Netflix and not ruin here MacBook by letting it run continuously. I used the MacBook on a smaller 14" and the 26" Vizio with no problems. The iMac won't see either one though in sys prefs it does show the display but won't mirror. If you, for some reason, just cannot answer the question, just let me know, I appreciate all your help. I am at a loss but feel certain there is a way to do this.

Two hdmi displays to the Mac Pro cylinder

How do i hook up two hdmi displays to the Mac Pro cylinder?

There are cheaper adapters and cables

<http://store.apple.com/us/product/HA825ZM/A/belkin-mini-displayport-to-hdmi-cabl e-2-m65-ft>
but they are passive not active.
The new Mac Pro can use a maximum of two passive adapters (the built-in HDMI port counts as one), so you could use one passive adapter, but any more would have to be active.
Some useers have reported problems with cheap Mini DisplayPort to HDMI cables.

Monitor display no signal input

my computer turn on but the monitor display no signal input. I plug my monitor to other computer and the screen shows my icons and everything but when I plug other monitor to my computer it say no signal input. How do I fix my computer to communicate with the monitor.

When desktop goes blank then there's no more signal from the pc.
So the monitor says 'NO SIGNAL INPUT'.
What's the problem?

Daisy-chaining a HDMI display from the Apple Thunderbolt display

Is this possible?
Current information indicates that there is a lack of connectivity from the Thunderbolt display to the legacy MDP Cinema Display panels (although there is a work around). Is this the same for HDMI displays (considering most adapters are MDP to HDMI)? I'm wanting to connect a Samsung SyncMaster as a 2nd external display... Will be running off an early-2011 15 inch MBP (Lion).
Any thoughts / anecdotes welcome!

Yes, you'll need an intermediate Thunderbolt device to connect the 2nd non-Thunderbolt display, even with HDMI to Mini DisplayPort.

Macbook Air hdmi display not detected

Hi, my 2011 Macbook is not detecting my hdmi display - the screen flashes blue briefly but no display is detected in system preferences or anywhere else.
Any ideas?
+I am using a mini display port to hdmi adapter with the thunderbolt output and I've tried rebooting with display plugged in and my osx is 10.7.5 Lion.
Any help appreciated

Actually I fixed it in the end by getting a new cable, it turned out that for whatever reason my cable was not up to the job.\
I found that a cheap £5 one piece thunderbolt male to hdmi male cable off ebay did the job well and it was my two piece - thunderbolt male to hdmi female attached to a standard HDMI to HDMI cable which caused the problem.
Seems like HDMI can be quite fussy and either it works or it does nothing, no in between.
So my fancy mac now works great with my cheapo alba hdmi tv i paid £25 for and carries both sound and video!
(I don't think I'll go back to windows if I can help it, not after using a mac. Once you've had a mac you realise what a pain in the a*s windows is .. I hardly ever feel like punching my mac )

Is there any way to lock the HDMI display on one desktop?

Hello!
My Macbook Pro HDMI-connection to my TV works great -- the only thing I wasn't able to figure out is if it was possible to lock the HDMI display on one desktop. I use five different desktops (spaces) and I'm using extended desktop(s) for my HDMI, but every time I switch to another desktop, whatever I'm watching on my TV switches to the extended desktop for whatever space I just switched to, meaning that my TV switches to blank screens. Is there any way that, even if I continue switching through desktops on my computer, I can keep my HDMI locked on the extended space for "Desktop 1," for example?
Hope that makes sense. Thanks!

If you disable the "Change with buttons" setting, the buttons will still control the general volume (music, games, etc) but will NOT change the ringer or alarm sound settings (keyboard clicks also fall into this category but is not mentioned). This lets you use the volume up/down buttons to change the general volume level without changing the ringer and alarm volume levels...it keeps you from inadvertently turning down the ringer or alarm volume and missing calls and alarms.
That being said, there's no way to totally disable the volume up/down buttons from doing something volume related.

Displaying analog signal in case of glitch

I want to display the signal in the analog format
Since there is a glitch in the first few ns the actual graph gets suppressed to represent the glitch in the available range.
Is there a way so that it would display the required waveform correctly.

I am using suse linux and i am not able to enter anything in those boxes . I have changed the off scale to clip. recently i go the window without glitch and do reset zoom y . But when i change the window or zoom out the condition gets reset. As you can see in the images i get the the required graph but only part of it and after zooming out the glitches again start to dominate.i do not want to seet that part.my actual signal lies in low resolution.

TS4429 my ne keep displaying no signal no matter where i go. my phone just displays no signal. Iv tryed turning off, removing sim .airplaine mode.,allthe usual tricks still nothing.

Macbook Pro to Television display with HDMI cords "No Signal"

I cannot get my Macbook Pro to display on my LG TV when using an HDMI/mini port connection. I have checked the input and re-connected all of the cords, restarted the computer, etc. and I still see a "No Signal" sign jumping around my television screen.
I am updated to the most recent software (OS X 10.8.2) as well.
When I open displays (in System Preferences) it has "Show Mirroring Options..." checked off but no sign of my television.
I have tried looking through all of the other discussions and can't seem to locate my problem - Help please!

Early 2011 and later MacBook Pros have Thunderbolt, which is not 100% compatible with all mini-Displayport adapters. Double check yours is by contacting the manufacturer.
