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?

Monitor displays no signal, but cpu turns on

I am using a HP pavilion elite HPE and a HP x23LED monitor. This problem just occurred this afternoon and I have been trying to rectify it to no avail. Everything was working perfectly till today. I was on a game when the screen went black and displayed the 'no signal' message, and then went to sleep (led on monitor turned from blue to amber). CPU was still running and sounds were still playing. Subsequently I have been force shutting down and restarting the computer - the monitor will display images of the boot up process - sometimes up to the desktop - before going blank again. I have googled the problem and tried reseating the graphics card (and cleaning it) - problem persists. The same issue happens when I try using another monitor via another VGA cable. Any help is greatly appreciated. Will be standing by for reply! Thank u

Hello jgoh,
I understand that your display is black.
It sounds like the graphics card may have gone out.
Turn off the computer.
As you power it back on tap the F8 key to load advanced diagnostics.
Select safe mode.
Check to see if the computer will load windows.
You may need to take the computer some where local and have them check out the card.
Let me know how everything goes.

"No Signal Input" on external VGA monitor

About a year ago my 4 yr emac that I gave my dad starting having the video on the built in display go out periodically. When it started happening more and more, rather than get a whole new computer, we purchased a 22 widescreen VGA monitor and hooked it up via a mini-DVI to VGA adapter. Everything was great and worked perfect. Just last week all of a sudden the VGA monitor is displaying "No Signal Input" The emac is starting up and making all of the correct sounds, but no picture at all.
I've tried booting from a disk and that was unsuccessful. I've connected the monitor to a different computer (old Dell laptop) and the monitor displayed fine.
What are the odds that the Mini-DVI to VGA adapter just went bad?
The next thing I was going to try was to reset the Parameter RAM.
Any other suggestions?
My monitor also has a DVI input. Should I try connecting to it instead? (although I'll have to buy a new adapter for DVI).
THANKS

Hey Kat,
What are the odds that the Mini-DVI to VGA adapter just went bad?
That could happen. If you jiggle the plug you might get it to come back. I just had that problem on an iMac G4.

Display FFT of input signal which receive from VISA read ?

Hi.
I receive data from MCU whcih sampling frequency is constant and we assumed it is S. now I get data from MCU with using VISA read block. I can display data, perform some functios like filtering, multiply and save them in txt files. all thing is OK.
but when I want to see FFT of incomig data on chart , it doesn't work !! I use this VI for calculate and display FFT of input signal (from VISA read) and display it which in Y-Axis is magnitude and X-Axis is frequency.
in your mind why this is not work and what I must done for show input signal FFT and frequency components ?
Thanks.

If I understood this correctly, you are getting the correct results when outputting to a text file but you are not able to see the results when trying to output to a chart?
This discussion may be of some help to you.

MacBook Pro 13 + LG W2240T - No external monitor display

Hi all. Have a brand new MacBook Pro 13 and LG W2240T connected with the MiniDisplay-->DVI-D adaptor. When I plug in the adaptor the screen on the Macbook flashes, the LG immediately says "DVI-D Power Save Mode" and then goes black. When I click "Detect Displays" it shows that no external monitor is attached. If I unplug the connector the MacBook display flashes. I think the Macbook is seeing something but it isnt sending a signal to the display. If I unplug the cable from the monitor I get a general "check signal" message floating around the screen. Dont think it is a problem with the screen. I dont want to have to shell out another $30 for a MiniDisplay -->VGA adaptor and use an analogue signal with the beautiful new digital display.
Any hints or suggestions appreciated.

I'm having the same trouble. Actually, my Macbook detects the monitor but no signal is reaching it. I am using a DVI-A cable from what I can tell. There appears to be a DVI-D or DVI-2 type cable available as well.
The connection is as follows:
Macbook Mini Display Video output to (Mini Display/DVI adaptor) then the DVI-A cable to a DVI/VGA adapptor (sub-D monitor connector) to the external video monitor input. I can see a "No Signal" message when I use a "picture in picture" function on the external monitor screen but get just a black screen with the monitor set to full screen VGA input.
So do we think the trouble is the type of DVI cable or is there some further Mac secret handshake that I need to prompt the output from the Macbook. The odd thing (to me anyway) is that the Macbook recognizes the monitor by its brand and model number after doing a "Discover Monitors" search. But the signal does not reach the monitor and I don't know if there is anything else I need to do or if it just doesn't work.
Further info is that I just tried disconnecting the DVI input, which I use as the main video connection to my monitor and I get the stock "arora" screen image from the Macbook but that's not what is currently being viewed on the Macbook screen. So perhaps I can just set the Macbook to "Mirror" the displays and use the DVI connector. The trouble with that is that the DVI connector is occupied on both of my external monitors. I haven't even tried the other monitor yet as it's a plasma TV in another location.
What do you guys and gals think is the best and most cost effective fix here? I just want to be able to output signal from my Macbook onto the larger displays so that I can work more comfortably.

Monitor says - "No Signal"

My G3 has been connected to a 21" Dell (really a Sony Trinitron CRT flat-screen) for over 6-1/2 years, and worked flawlessly. One day, on start-up, I get a blank screen with a terse message… "NO SIGNAL." (!!) Checked all the connectors, pulled & reseated the video card (an ATI Rage 128 of 16MB, rev. 1- #661-2190, with the extra MPEG-2, DVD decoder- #661-2109); after two days of non-sense, took it to the shop… where it worked flawlessly on THEIR service counter! The battery needed to be changed, and was. Took it home, and it was "s-o-s." "NO SIGNAL."
Out of desperation, I connected a spare 20" Apple Multi-scan CRT (also a Sony Trinitron), and everything worked… 1-2-3 and we were on the desktop. Over the next two weeks, the Apple Multi-scan never failed to work.
Thinking that I had a +monitor issue,+ I acquired a Sony 20" TFT flat-screen. Connecting it up, I got the same results… a blank screen with the terse message… "NO SIGNAL !!" Unsavory language followed. Sooooo, I acquired another video card. Inserted it and connected up the flat screen. Again… NO SIGNAL !! The G3 was on the counter four times and worked like there never had been a problem. Even when I took the G3 in with the Sony TFT flat-screen. They said to hold down the Command-Option-P & R keys on start-up. This will bring the flat-screen up, but on start-up later, itz back to business as usual. IF my video card were the problem, the flat-screen would NOT work at all; once up & running, I've made changes to all the monitor settings- to my satisfaction. I've run it for three hours. Re-setting the P-RAM has not changed the blank screen & NO SIGNAL problem.
So, for now, itz the G3, Multi-scan and me. The flat-screen sits. Appearantly, there seems to be BOTH a hardware and software problem. But I'm leaning more towards the software. However, my brainbox DOES know what monitor is connected to it, viz the DISPLAYS pane.
WHAT say you– Grand Wizards?

Hi! and THX for your reply . The Sony TFT LED flat-screen has 2 RGB analog inputs (J15 & J16) and 1 DVI-D (J17); the flat-screen knows which input is connected to the G3. In the downloaded Sony TFT LED Computer Display manual, on page 15 - under the "INPUT SENSING ON/OFF menu," the monitor automatically detects an input signal to an input terminal and changes the input automatically. While there are no specific "switches," there is the menu. Apparently, I can turn off the *automatic sensing* and manually set the input. I haven't "tried"that just yet. When I rise to the chore of moving things all around again, I'll try manually setting the input. However, I doubt that this will have any effect on things.
Not to throw more dust into the air and further confuse matters, I am begining to suspect my original OS X 10.3 install disk; the one I acquired was for/from a 12" PowerBook G4… @ the time, brilliant me said… "So itz for a 12" PowerBook, so what? Itz Panther, right??" After the original install, there followed 2 updates,the last one being 10.3.9; up until recently, there have been absolutely no glitches on start-up. ALWAYS full-screen… until about a week ago. NOW, the last half dozen start-ups, have been with the reduced screen (the gray "bite-of-the-Apple) for the 12" PowerBook (!!). In any event, I am acquiring a "regular" version of the Panther install disk.
I find it strange that what triggered this whole mess (apparently) was failure of the PRAM battery. Or perhaps, that was just coincidental? REGARDS.

PPC G5 with ATI Radeon 9600 Pro monitors not getting signal

hi there.
I have a PPC G5 with ATI Radeon 9600 Pro graphics card and I cannot get a monitor to work properly. I am trying an old Apple Studio Display (circa 2001) and a Viewsonic VA520.
It seems like the Apple display should work, but all I get is a black screen. I ran it through a DVI to ADC adapter and had it working for a short period of time, but for some unknown reason it went back to the black screen.
The Viewsonic gives a 'NO SIGNAL' screen and not much else.
Both of these monitors have worked on other G5's. I am guessing this is a graphics card issue.
I appreciate any kind or helpful words! Thank you.

I'm having a similar problem with the G5 not recognizing a VGA monitor on either video out. I have no problem using two monitors with the DVI inputs but I need to use a VGA video splitter for a third screen. It worked at the beginning of this week, and now it refuses any VGA out, even without the splitter, just going into directly into the VGA in of one of my working monitors via a DVI-VGA adapter(i've tried different ones). I read another post about trashing "displays" and "windowserver" preference files but i haven't yet tried that..any clues??

Aspect ratio of NTSC monitor display

We're working on a FCP 4.5 project that's shot 16:9, and displays with the correct widescreen aspect in the canvas window (so long as pixels are displayed square). However, when I run mirrored video through a Sony DSR11 deck to an NTSC monitor, the picture appears stretched vertically (to fill the screen). How can I correct the aspect of the display in the monitor?
Thanks
Matt Clifton

If I read right the poster is working anamorphic and wants to monitor it properly. Anything that creates a letterboxed display on 4:3 (including a deck conversion will not be monitoring the true signal. It will be a downrezzed and substantially mashed version.
If you need to truly monitor anamorphic output, just "anamorph" the monitor - see above.

How can i display the signal out of a FFT block to a graph?

What conversion is required in order to convert a the output of a FFT block to a waveform display? The signal input to the FFT block is a binary pattern signal!

Hello St Augustine,
Unfortunately, I cannot open these files that you have attached so I cannot tell you for certain where your problem lies. However, if you are using one of the FFT VIs from the Analzye>Waveform Measurements sub-palette, then you should be able to wire directly from the VI to a Waveform Graph. Make sure you are trying to wire to a Wavform Graph not a Waveform Chart. If you are using the FFT VIs on the Analyze>Signa Processing>Frequency Domain sub-palette, you should also be able to directly wire into a Waveform Graph, but please refer to the KnowledgeBase document linked below for more information about plotting complex numbers.

New monitor not recieving signal via DVI, ok via VGA

Hello,
I have one of the original minis (1.25 GHz, 512 MB, etc) purchased back in early 2005. Until now I've been using an old CRT display connected via VGA. This past weekend I purchased a new 20" AOC LCD monitor from Costco. I attached it with the supplied VGA cable and it worked great. The next day I picked up a DVI cable, attached it and after a minute or two the monitor found the signal and displayed a beautiful image. After five minutes the monitor lost the signal and I haven't been able to get it back since. I exchanged the DVI cable for a new one, but still can't get a pic displayed. The monitor itself is self switching. It knows if the connection is via VGA or DVI.
What am I doing wrong? Could it be the mini? The monitor?
Please help.
Thanks
Dave

Yes, it is a display specific issue. If you look at this Apple spec page for the original mini and do a search on the word "coherent" it will take you to the part of the spec that deals with the issue.
http://support.apple.com/kb/SP65
Apple displays are not a problem because they have always used coherent receivers. But any other monitor is a roll of the dice, especially with the original mini. The newer mini with GMA950 graphics appears to be much less affected by this even though Apple left the wording in this part of the spec unchanged between the original G4 mini and the current Intel ones.

Srceen goes gray after the apple goes off then the monitor says no signal..

srceen goes gray after the apple goes off then the monitor says no signal.. It been working great for 9 months use it everyday for fcp.. would the video card be bad???

If the video card were bad, you wouldn't get anything to display. The fact that you get the gray screen with the spinning gear means the video card is working.
So, two things I would try, and you can pick the order. The first is to reset the PRAM. You may want to save this for last since it will reset a few of your settings. Nothing major, but can be annoying. The second is to start the system in safe mode by holding down shift while booting.
If safe mode works, then you have some corrupted preference files or some other program is causing problems. If safe mode doesn't work, you can at least see if zapping the PRAM lets you get any further along with the boot process. Only if both of these fail would I start to consider an issue with the video card.

In Labview 8.5, what happens if the signal input exceeds the signal input range set by the DAQ Assistant?

Hello all,
This should be a pretty simple question, but I can't seem to find the answer on-line and don't currently have the capabilities to test this:
I'm using LabVIEW 8.5 and have a VI that imports sensor data through the DAQ Assistant. In the configuration tab there is a signal input range. What happens if my sensor exceeds this range? Will I get a warning? Will the value default to the maximum (or minimum)? I was interested in writing in some code to display an error as I approach the limits of this range, but was unsure if I also needed to include some code to display an error if the range is exceeded as well.
Thanks for the help,
Tristan
Solved!
Go to Solution.

Hello Tristan,
The behavior depends on the range you choose and the device you are using.
If you are using a device with only one valid input range, we will use this range even if you set a smaller minimum and maximum in the DAQ Assistant. Thus, if your device only supports ±10V and you set the range to ±8V, you will still continue to get valid data after your sensor exceeds 8V until you approach 10V. Once you reach the limit of the range of your device, the output will "rail" and just return the maximum value until the signal drops below the maximum again.
Note: A device that is nominally ±10V usually has some overshoot (like ±10.2V) that is typically specced in the manual.
However, if you are using a device with multiple input ranges then things get more complex.
The NI-DAQmx drive will pick the smallest range that fully encompasses the range you choose. So, suppose your device supports the following input ranges: ±0.2V, ±1, ±5V, and ±10V and you choose 0V - 3V as the range in the DAQ assistant. The NI-DAQmx driver is going to look at your input range and the list of input ranges that your hardware supports and choose the smallest that encompasses the full range you set. This would the ±5V, because that's the only range that contains up to 3V. As a result, any input signal between ±5V will be returned and any outside this range will "rail" to either the maximum or minimum value.
We do this because using smaller ranges make more effective use of the resolution of the ADC. Thus we try to use the most efficient range based on what you request without picking a range that will cause you to miss data.
Let me know if I can clarify this further.

Hello chf,
When you boot up your computer a message on the monitor displays that it can't get a signal. The issue could be a few things so we need to start ruling things out
1. Try another monitor on your computer
2. Try another cable
3. Try a different type of cable if your computer has multiple connections
Are you using integrated graphics or is it a discrete graphic card, if discrete which one?
Did it used to work and just stop one day or has it never worked?
