No signal from my computer to TV or Projector through HDMI

When I tried to connect VGA cable to the HDMI Cable that came along with my notebook, I am not getting the display either on TV or on projector

Hi Zack1,
Try this to see if it helps. Download the Chipset driver and Graphics driver on the links below and save the installers to your Desktop.
Chipset
Graphics Driver
Next, in Device Manager, open Display Adapters, right click on the Intel graphics chip and select Properties. Click the Driver tab and then select uninstall. When done, do the same for the for the Intel High Definition Audio Codec found under Sound Video and Game Controllers.
Now return to the Desktop and install the Chipset driver and then the Graphics driver. When complete, reboot the PC and see if this has helped. Check in Device Manager that both the Intel Graphics and the Intel Hi Definition Audio codec have reinstalled successfully and whether you now see the HDMI Audio option under playback devices ( found in Control Panel, Sound ) as shown as the top option on the screenshot below ( ignore the fact that it's ATI, i just mean the TV icon option ).

If it shows up correctly, try the HDMI connection and see if it now functions properly.
Best wishes,

I am having trouble sending an audio signal from my computer (mac pro early 2009) to my TV. Is there some interface or adapter that allows /enables the audio input from my computer to be sent to the TV (R,L signal?) any suggestions

just the audio, eh?. If you were using DVI or DisplayPort that might be different, but for audio alone, it shouldn't be that hard. Just grab a 3.5 mm stereo plug to 2 rca cables adapter. Plug the smaller end into the back of your Mac Pro (or the Front), where you see either the headphone or speaker icon). Alt-click on the speaker icon at the top of your screen to show all audio inputs and outputs. Make sure it's set to Line Out. Plug the red and white end into the audio in jacks on the back of your tv and set it to the correct input. I don't know if your tv will allow just the audio to play. Usually one has to connect up something else, but hopefully I'm wrong. If you were using DVI, or DisplayPort, you'd need an active DVI--HDMI adapter or a DisplayPort to HDMI adapter, but
I don't know for sure

My ipod touch syncs no problem, I cannot figure out how to get my playlists or songs to stay on my ipod. I can get them onto itunes from my computer. I know how through homeshare but then they disappear as soon as I turn off the comp obviously. Thanks:)

Thanks in advance for your patience and time with a newbie:) I can sync my ipod touch to itunes no problem, I figured out how to get my music from my computer onto an itunes playlist, my problem is how to get it to stay on my ipod. I made the mistake of using home sharing which of course turned out to be useless as soon as I turned my computer off, within minutes my ipod library disappeared. I feel like I am missing something simple, any help would be greatly appreciated. Thank you again

I figured it out, thanks anyways

Hp laserjet 1300 not receive signals from computer

HP Laserjet 1300 seems not to receive signals from my computer. Please explain

Are you networked or USB cabled into from the printer into the computer?
What OS are you using?
If you are on windows 7 and networked in, then you need to check and make sure the that the IP address of the printer is listed as the same in the port settings.
If you are on windows 7 and are using a USB cable, then you have to load the printer through the IN-OS driver. See the link below...
Install the driver included in the Windows 7 operating system (OS)

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.

I have an HP2055dn printer that isn't receiving a wireless signal from an Mac Airport router.

I moved the printer and it doesn't receive the wireless signal. Does the printer need to be attached to my computer for it to receive a wireless signal from another computer?

Hi,
Do you use access point (AP) for your network ? The printer needs to be close to the AP, not computer(s). One option is to have a booster/amplifier but this costs money and time.

What do I do when I want to change the sound output from my computer to my TV but I do not have the HDMI option under sound output?

I have the first generation of the silver macbook (with the black keyboard- before it went to macbook pro). I have been watching movies from my computer onto my TV via a HDMI cable. For awhile now I have been trying to get the sound from my computer to go onto my TV, but I do not have the option of HDMI on my computer. I was wondering if anyone knew why or what I do when I do not have that option. Thank you!

With the Late 2008 model 5,1 Aluminum Unibody there is an adapter that uses the Mini DisplayPort and a USB port to combine video and audio to HDMI. It's only 2 channel stereo not 5.1 Dolby Surround.
http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10428&cs_id=1042802 &p_id=5969&seq=1&format=2
If you connect the MacBook using a Mini DisplayPort to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo sound system if your TV doesn't have separate RCA input plugs or a 3.5mm stereo input plug for audio with the HDMI plug. The Mini DisplayPort to HDMI doesn't carry audio unless you have the Mid 2010 model 7,1 and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.

Read in signals from a usb 6212 in more then one computer

I have a NI-USB 6212 to read in signals from a industrial proces in the computer. This computer has also a touchscreen so workers can select a reason why the proces is stoped. Now the problem is that this has to happen at two places so with a another compter and touchscreen plus on a another computer has to monitor on a big screen al the procesvariabels. I want to do this al with LABview. What is the best way to do this?
Kind regards,
Solved!
Go to Solution.

fille,
if the signals that are acquired by the 6212 are not too fast, you could write the acquired data to network published shared variables. If your second PC has a network connection to the first one, you will be able to access these shared variables there.

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
Best regards,

Getting Started with Labview.pdf ‏901 KB

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.

Warning: I am not a tech-pro!
Okay, I have a 2011 Mac Book Pro running OS X LION 10.75 (11G63) unsure what those last numbers mean but they were there so I thought perhaps it might be helpful to add them.
Recently I moved into a granny flat and pay $10 a week to use their unlimited internet wifi. I log into my wifi through this device called a WiFi Repeater? It's plugged into the wall in my unit, as I warned I am not incredibly tech savvy so I am only guessing when I say I suppose this extends the main wifi signal from the actual home owners upstairs big modem? Any who.... A few times I have seen in the Finder Memu ot says 'Shared' and under that 'Wendys PC' (Wendy is the homeowner) then if you click on it it tries to connect but won't or there is a 'Connect As' option which brings up a little screen saying - connect as wendy, which requires a password or connect as guest which doesn't look like it requires a password- I'm not certain because I've never tried to connect any further, I only pressed that initial connect button when I had mentioned to Wendy I could see her PC & she asked me to press connect & prove I could not in fact connect (I'm starting to despise the word 'connect' since having to type this post about connection). So... We just kind of let it go. It did really worry me that Wendy (who worked in the tech field for years in particular with an Internet provider, could possibly connect to my computer and nosey through all my files- and to be honest, that would not actually suprise me. She is incredibly 'inquisitive'... And that's putting it mildly. I do have a password on my Mac Book Pro but I don't think that would be that hard to break through/hack if you have the knowledge/software. And yes, I do have confidential files on there! Banking/business/private photos (I'm trying to lose weight so take one nude photo per day to do a time lapse of myself in a year or two- obviously for myself not for others eyes lol and I would literally die in the *** if someone ever saw these). So basically I have good reason to protect my privacy. As does everyone! Anyway my first question is - Could she log in and how could I tell if she had? Now, the second part of this ridiculously long question (my apologies) is I was logged into my personal account all last night & this morning. As I stated- it IS password protected. The user account is not. Before I went out (and I can't actually recall if I closed the lid or not when I rushed out today... Usually I do but maybe I didnt... Whatevs) So, I get home and activate the screen by moving my finger on the touch pad and lo & behold I'm straight away looking at a totally different screen? It took me a few seconds to realise why my desktop looked completely different with none of my files etc... It was - as you've probably guessed- because I was in fact in the guest user account. Now, I didn't even have to click ON 'Guest User' as I normally have to. When you turn my Mac on it always comes up with - 'My Full Name' (one account login) and then 'Guest User' (the second account login option).... So you HAVE to choose which one you want! But my screen was straight away logged into the Guest Users desktop! I did NOT do this guys! So, of course now I'm extremely concerned that either she, her husband or their son whom is visiting for the weekend - have either a) logged in remotely on one of their computers or b) have come into my home and tried logging in & then forgot to log out of the guest account. I want to know if there is any way to find out what they did, what they opened if they did, how to stop it from both happening at all or if my suspicions are in fact happeninh AGAIN And I guess on a more personal, less tech involved note - how would you all deal with such a situation? Let it go? Or be upfront about the fears/concerns I am experiencing since moving in just over a month ago. AND most importantly - IS there any other reason -other than someone physically logging into my guest user account & failing/forgetting to log back out so that when I got home & activated my screen I was actually looking at the guest user desktop's account instead of the Mail application screen in the 'My Full Name' password protected user account where I had actually left it before rushing out.... Like, is there ANY other possibly explanation for my user account being logged into when I'd left it on my own account t before I left that doesn't include someone in the house hacking/breaking into/snooping through my Mac? Also- you should understand that when I leave my Mac for just a few minutes I have it set up so that the computer screen 'sleeps' (I'm assuming that's the correct term) so that if for instance -exactly like this morning- I have to rush out and don't want to/don't have time to save work/quit applications/shut down etc... I can walk away leaving the laptop as is knowing within a few minutes the screen saver comes up (and if that's ledr for long enough it goes into sleep mode) and no one can actually enter my private account without my password. I feel safe knowing that.
Sorry.... I FELT safe.
I'm truly sorry for how long-winded this question has become, I simply wanted to give anyone possibly willing to help me sort out this issue, as much information as possible. I think I have actually only posted here once before (I find these sort of forums quite intimidating) and I often see people getting bashed for not providing enough information. So, I'm pretty sure I'll get picked on for too many words if anything!!?! Lol
Thank you, in advance for your help!

Ouch.
Not easily. You could try data recovery software... maybe SubRosaSoft's File Salvage or the like.

Is it possible to get 2-ch signals from TDS2012 oscilloscope at the same time with LabVIEW "7.0"?

Hi, everyone.
I've been trying to get the signals from 2-ch of Tektronix TDS2012 oscilloscope at the same time using IVI connection with LabVIEW "7.0"
I've already searched this developer zone for the answer.
I've tried the famous example: "IviScope - Acq Dual Wfm Edge Triggered.vi"
and it gave me the error message like:
Error -1074110451 occurred at IviScope Initialize With Options.vi
Possible reason(s):
Driver Status: (Hex 0xBFFA600D) Primary Error: (Hex 0xBFFA600D) The Config Server module is not present on the system.
I think I've installed all~ the required softwares for IVI. For example, ICP 2.2, IVI engine 2.0.46, and tktds1k2k ivi (instrument driver for tds2012, in fact this one is for LabVIEW "7.1"... :-P)
TDS2012 and my computer is connected through HPIB(GPIB) and it is shown on the MAX (a GPIB instrument as well as an IVI hardware asset)
I've tried GPIB connection but it gives me asynchronous signals...
Is it possible to get 2 signals at the same time with LabVIEW 7.0(not 7.1 or higher) by any means?
What in the earth is the "Config Server" in this case?
I don't need to sticking to IVI and any method to achieve my goal will be welcome.
Could anyone give me the hint for this problem, plz?

I think your problem is that the instrument specific driver is version 7.1 and you are using the class driver with 7.0. You can create your own 7.0 driver by downloading the LabWindows driver and using the Import CVI Instrument Driver under the Tools>Instrumentation menu.
Since you don't seem to have a good reason to use IVI, why don't you try the native LabVIEW driver at http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9139659CE034080020E748.... I believe you have all of the functions to setup each channel and then when you trigger the scope, both channels will be captured. You would then transfer each waveform separately. The data is always read sequentially but that's not important as long as both channels are triggered at the same time.

Best way to Boost Signal from a Time Capsule is?

Is the best way to boost my wifi signal from the time capsule an Airport Express?
Is there anything out there better, faster?
Thanks!

There's a good step by step in the Designing AirPort Networks guide, pages 43-44.
http://manuals.info.apple.com/enUS/Apple_AirPort_NetworksEarly2009.pdf
When you are configuring an AirPort Express with AirPort Utility, it will usually help to temporarily connect an ethernet cable from your computer to the Express. Once you have it configured and updated, you can remove the cable and move the Express back to the desired location.
The key things to keep in mind are that both the base station and the extending device must be configured. All you will need to do on the base station is open AirPort Utility, click Manual Setup and Click the Wireless tab. Make sure there is a check mark next to "Allow this network to be extended" and update to save changes. If you have a dual band base station, only the main network can be extended.
On the Express, the Wireless Mode is set to "Extend a Wireless Network". When you do this, the wireless network created by the base station will appear so you can select that network to "extend". You will need to enter the password for your wireless etc. It's important to remember to click the check box next to "Allow wireless clients".
By the way, the ethernet port is also active when you setup the Express to extend, so if you need to get ethernet to a device like a DVR, DVD player, etc., this is a nice way to do so.

Why is the Analog signal from the FPGA is distorted?

Hi,
I am using the PXI-7831R board with LabView 2010. I'm trying to transmit TDMS files from the computer hard drive via the analog output of the 7831R. I've used the "Basic DMA output - R series" example and replaced the generated signal with a TDMS file. When I tried it on a synthesized pure sine file, it transmitted the positive part of the sine wave (which was a little distorted) but instead of the negative part I saw 0V DC. When I tried to use a "real" TDMS file (that I sampled earlier) the signal came out completely distorted. In both cases I used a graphic output in the host VI and checked that the data coming from the file is ok. Can anyone help me with that?
I would also appreciate some explanations on the "Update Rate" block (I suspect that he's the one causing all my trouble) - how am I supposed to use it and is it mandatory?
Thanks in advance.

It sounds like when you are using the sine wave, you are clipping the data. I am assuming that this is because you are sending it negative values. R-Series cards can not handle fixed point values, so try to offset the signal so that the lowest point of the signal is at 0. See how that works for you. As far as the Update Rate goes that controls the speed of your loop. If you do not set it high enough, the loop will simply run as fast as it can. I hope you find this helpful.

No signal from a Roland SPD-8 drum midi controller

Hello!
I've just purchased a Roland SPD-8 drum MIDI controller. It's quite old, so I've had to get the MIDI to USB converter to connect it, but my computer is picking it up.
No matter what I try, I can't get a signal from it in Logic Pro X. I have a USB MIDI keyboard which works perfectly after being plugged in, but this is one's impossible! I'm lost.What are the correct settings for this? What have I missed??

Spotlight doesn's search Library folders, maybe that's why you don't find anything. Take a look at these two folders and remove anything that you don't need (i.e. remove anything that you don't know - in a basic setup, there should be nothing in there):

No signal from airport extreme after switching to optimum online

I am pretty new to macs and this is my first message posted. A few days ago I switched from Verizon FIOS to Optimum Online and they changed the modem to a Motoroal Surfboard model. As far as I can tell the wiring was done correctly, but now my airport continues to blink amber and I am not getting any signal from it. The only way it gets picked up is by connecting the ethernet from the airport directly to the my macbook. I tried doing a soft reset and a hard reset, but still no luck. Optimum Online is telling me that it is a mac problem, but that seems odd to me since it was working fine before they switched modems. I know the new modem works because I can access the internet directly through it. When I go through airport utility, it keeps telling me that I need a firmware update, but then it cancels out on me with Error Code 6737. Any ideas??
thanks,
Ralph

Some thoughts that may help with your problem:
1) When you connect directly to your new modem, open the "Network" panel of System Preferences and check the "Built-in Ethernet" item to check the setting of the "Configure" drop-down list. It will probably be either "Using DHCP" or something mentioning "PPPoE". Your AirPort unit should be configured using the same method.
2) When you switch between having your computer connected to your modem and having your AirPort unit connected to the modem, you ought to cycle power on the modem. Some modems will lock onto the MAC address of the client device and will refuse to work with anything else until they are reset.
