"No Signal" from DVI on Viewsonic VA912b display

I'm trying to usu the DVI port on my Dual 1.8 G5 (10.3.9), but all I get is a few seconds of the Apple boot screen and then I lose the signal. My display works fine with the VGA adapter, but I'd prefer to use the DVI if possible.
Any and all help would be greatly appreciated.
Namaste.
Dual G5 1.8 Mac OS X (10.3.9) ViewSonic VA912b display

VGA and DVI are managed by the OS as two completely different interfaces. When you switched the VGA setting to 1024 x 768, that has no bearing on what the DVI port outputs. So when you swapped the interface from VGA to DVI to the monitor, the Mac was outputting the same (invalid) resolution as before and not 1024 x 768.
Are you really running 10.3.9 as in your sig, or are you running Tiger? There is a way to switch resolutions using the keyboard without benefit of a useable screen under Tiger. Or you could also establish a VNC connection to a second computer on your network and change the resolution on your G5 using the VNC client.

No signal using DVI cable from mac mini

I have the dell 2007wfp monitor and I can't use the DVI cable I get the message No signal coming from your computer. then the display goes to sleep.
It works OK with the DVI to VGA but everything is stretched and peoples faces look weird.
I have a mac mini 1.66 dual core with 2 gigs ram and 667 mhz DDR2 SDRAM.
The monitors max res is 1680x1050.
Any thoughts?

+Could it be that some monitors are harder on the video card/cpu?+
Yes, in a manner of speaking. In fact, Apple says as much. Some displays are "coherent" and some are "non-coherent" and they get treated differently by the mini. It says so on this Apple spec page for the mini in the second column under "Graphics and video support".
http://www.apple.com/macmini/specs.html
Of course the problem is how do you know which you have, a coherent display or a non-coherent display? Answer: you don't until you get your new mini or new display home and discover the two don't play together.

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

Getting Started with Labview.pdf ‏901 KB

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,

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.

Is it possible to input itunes into DVI/HDCP input from imac with Apple mini display portS?

Is it possible to input itunes into DVI/HDCP input from imac with Apple mini display port? Or is there another way?

The problem with itunes is needing a computer running it. or continuous internet connection.
A Time Capsule is AC mains powered.. no battery. Although you can certainly buy an older Gen4 TC and modify it ...
https://sites.google.com/site/lapastenague/time-capsule-power-supply-repair-kits
I have run my TC on a 12V SLA battery.. which would neatly meet that part of the functionality you want. But it is heavy and not really the rugged sort of device I think you want.
But I would look at other media players and other ways of storing movies than iTunes.. if you want to carry the whole lot around with you .. A bunch of SD cards even you could plug into the ipad??
External storage for iPad?
A small cheap PC/Mac laptop with a 1TB hard disk in it.. and 11" or 13" screen.. can often be a much better solution than lugging around multiple items so you can fit Apple devices into your life.

ViewSonic VA912b not working with new MacBook Pro i7

Hi --
I just received my new MBP on Wednesday, along with it I purchased the Griffin Video Display Converter (http://store.apple.com/us/product/TY600VC/A?fnode=MTY1NDA3Ng&mco=MTY4NzA5MDY) so I can use the computer with my ViewSonic VA912b 19" monitor w/ DVI at my desk, and my television w/ HDMI in the living room. I've plugged the monitor into the adapter and nothing is happening after hitting 'Detect Displays' in the Display menu. For the computer I had prior to this (2007 MBP), I had no problems hooking up this monitor and it would automatically find it. I looked through the user's guide and did some searching on the web and I'm finding nothing about this topic...does anyone have any insight into this?
Thanks in advance!
Kristina

No signal from HDMI...

Hello, I just got a pavilion HPE, 2nd hand from a trusted source The device came with a Geforce GT 260 (comes with a DVI and HDMI connection). I was trying to connect 2 screens, and there seems to be no signal from the HDMI connection.Is there any chance that this is not a hardware (display adapter/cable) problem? as far as I know all the drivers have been installed... Thanks! -Amit

Monitor not receiving signal from computer

I have an Envy 700-074 and I bought a EVGA Geforce GTX 660 (Superclocked) video card to use with it this past July. It worked very well for the past few months until mid-September when I started having problems while play WOW (I had no problems playing other games that required more video than WOW or in doing my 3d rendering). So two days ago I contacted Blizzard support for advice and they told me to run this display driver uninstaller from guru 3d to totally remove the nvidia drivers from my computer and then reinstall them fresh. Well when I ran the driver remover program, my screen went black and now I can't get any display response at all from my computer. The monitor says it is receiving no signal from my computer. I tried with both a DVI hookup and a VGA hookup and got same response. Please tell me what I can do to fix this. I need my computer.

Mac Mini not transmitting through the DVI cable to the display.

I have been using my Mac Mini with a MAG display, no problem. While traveling I used a Samsung display for a month no problem. Now I am back home and the Mac Mini will not transmit a signal to the MAG display. The cable and DVI converter are good and work with the MAG when plugged into my laptop, but not when plugged into the Mac Mini. How do I fix this problem? Thanks.

Apple recommends starting the TV/display first. Connect the cable and adapter to the TV and turn on the TV. Turn on the Mac mini and after it has had time to start up completely, connect the adapter to the Mac mini. Hopefully the mini gets the proper EDID signal from the display and adjusts its signal output accordingly.

No signal from Apple TV

I just got the new Apple TV and get no signal from it on my HDTV. I have an older Samsung TX-p3064w which has DVI and not HDMI.
I used a DVI to HDMI cable but get no signal at all - just a blue screen which means the tv received no signal. I know that DVI is not supported, but I was hoping to use this before I had to buy another T.V..
The T.V. can do either 1080i or 480p using DVI. I tried using two cables and no signal.
Does the T.V. have to do 720 in order to give a signal? Is there a certain cable I should try?
Any ideas on why no signal?

I was experiencing the same problem and discovered it is actually a 'handshake' issue. The firmware on the TV needs to be compatible with appletv. I solved it by updating the firmware for my Philips LCD 1080p tv. If you are using an older tv, you probably have to go to the manufacturer's support website to download the updated software on a gig stick and then upload it onto your TV. It should work thereafter. Good luck.

No signal from audigy 2zs line out j

Hey there....due to a virus, I recently had to format my dri've and reinstall XP and all my apps including software for my Audigy 2 ZS soundcard. Before the format I had my sound and video card connect to my TV to extend my PC display and audio to my home entertainment system. The external speakers were connected through the line out # jack on the rear of the sound card and I could hear everything playing just fine when my TV was on and the correct video signal line input was selected (video #2 in my case), but now I can't hear anything (video is playing back fine on the TV, just with no sound). I've checked my audio settings and I think they're correct - if there is a mute switch for any of the line out jacks in the creative audigy software or in windows' volume control panel I sure can't find it.
I'm sure its a settings thing because I didn't touch the cable connections, and I double checked to ensure they are all connected tightly/correctly as they were before the reinstall.
If anybody has any pointers, man that would be helpful....thanks!

Yup, my digital speakers are connected through the digital out jack.
Device manager shows the device working correctly - no issues or exclamation marks.
Not one ioda of hardware was moved, not one cable unplugged or any other config changed before or after the re-formatting of the hard dri've. Software o/s and applications only.
The soundblaster card properties in device manager shows no conflicts....everything is working fine, but there is a setting somewhere that is being missed I suspect; I have gone ever every option in all of the soundblaster audigy audio control software installed that came bundled with the card, checked online for latest drivers which I've got installed, and did a clean uninstall/reinstall using creative's 6 step-by-step guide. I also checked all windows xp based audio controls even though I've checked the option that enables the audigy controls to sync with the windows ones as you probably already know.
To my knowledge, there is no way to disable line out signal from this card - its there, you plug in your external and go. And with no config changes at all, no hardware changes, no cables unplugged etc. I don't know what else to do. (except email creative support which I did a few minutes ago).
Thanks Katman.

HT1454 Can I send audio and video signals from sling box on my IPhone to a tv using any of these cables?

I have an iPhone 4 and would like to stream the sling box signal from my phone to a TV. Is there a cable that will do this? I have heard that the only thing you can show on the TV from your phone is content stored on your phone.

TV out on the iPhone 4 only display video out for the apps that support v'ideo out. The app description in the App store will say if it supports TV out. iPhone4S will mirror the iPhones screen with VGA or Digital AV adopter.

Get the blue screen but the TV doesnt find the signal from my mac via hdmi

Before my mac could connect to my TV Samsungs LE32B350 without any problem, but now it just keep saying no signal from the tv. I get a blue screen when I connect the hdmi on the laptop for one sec then nothing happens. I have tried search for more screens but aint finding anything.
Please help me

Unfortunately older G4 minis are very touchy about certain hi-res monitors when run from DVI. Hi-res in this case means any monitor whose resolution causes the pixel clock to be above 135 MHz. It is normally the case that 1680 x 1050 timing will have a pixel clock above 135 MHz, although there is no way to observe that directly from within OS X.
There are only two known work-arounds for the issue. One is to run the monitor over a VGA interface. The other is to use a program like SwitchRes X to lower the pixel clock below 135 MHz. If you choose to do the latter, write back if you'd like some guidance on how to do that.

Acquiring analog signal from PC mic

Hi Guys,
Is it possible to acquire a signal (audio) from a laptop mic and display it in Labview? I know this can be done with a DAQ card but I was curious if I could bypass that and just use the mic in my laptop.
Thanks.

Here is a higher level example, for LabVIEW FDS:
