VGA cable question, and a problem

My PowerBook is connected to my 17" LCD via the cable that was included with the monitor. I bought a replacement VGA cable the other day. (I needed the original VGA cable to connect my Mac mini to the TV.) The original cable works perfectly with both the LCD and the TV. With the new cable there's visible ghosting appearing when connected to both the LCD and to the TV. What the ****? It's a brand new cable. It's a "Replacement/Switchbox Cable VGA/SVGA High Desnsity DB15 Male/Male" cable. Is that what I need? I noticed that the original cable has 15 pins and the new cable only has 14. Is that the problem? I didn't see any 15 pin cables at CompUSA.
Do I have a bad cable? To I need to return it in exchange for something else? What gives?

Welcome to the discussions Michael,
It sounds like a poor quality cable - either an individual dud or just a bad brand. I wouldn't worry about the missing pin - VGA cables have three pins that aren't used for anything, so manufactures often leave one or more of them out.
Take it back and look for a good quality shielded cable. Ask the the staff if necessary. It may cost you more than you spent on the one you currently have. Try looking for a Belkin cable - they're usually a good brand (assuming your current cable isn't made by them...)

VGA Cable Question

I have (3) 23" Sony CRT monitors connected.
Two of them have VGA cables with some kind of hard rubber capsule (about 2" long and three times the diameter of the cable itself) on one end. What is this "capsule". The tech at Best Buy said it was a "terminator". Is that correct? Is it needed? What does it do?
My 3rd monitor does not have this in the cable, but that is the one that just started experiencing wake-up issues.

It's nothing more than a ferrite bead encased in plastic around the cable end. Google Ferrite Bead and you'll see.
It helps dissipate high frequency "noise". The Best Buy tech is an idiot, so what else is new....
Has nothing absolutely to do with the problem though...

VGA cable extension causing resolution problems

Pavilion 6507c with HP 2010i monitor, Windows 7 64-bit. I am trying to separate the CPU and monitor by a few feet more than the original 6' VGA cable allows. Have tried an extension plus original, and also a single longer cable. With anything but the short original cable, the computer no longer recognizes the monitor - it shows it as Generic non-PnP, and will not allow 1600:900, so the picture is stretched. Re-installed 2010i drivers - still comes up generic.
Is there any way to extend the monitor distance without sacrificing proper resolution?
This question was solved.
View Solution.

I wouldn't be too concerned about receiving a no signal message when shutting the PC down. With a longer cable, the signal may degrade sooner causing the no signal message to appear during the shutdown process.
Displays work by the monitor sending the EDID information to the PC and this is part of how the PC identifies what resolutions are available to this monitor. The original cable is allowing this information to be sent from the monitor back to the PC. The PC then retains this information which is what allows it to work with the longer cable after swapping out the 6' VGA cable for a longer or extended one. Once the system is shutdown, the EDID information is lost. This is why it doesn't work once the system is shutdown and started with an extended or long cable.
You did mention an important difference between the cables: the lack of a ferrite core. This Wikipedia entry discusses ferrite beads (aka: ferrite core) and what use they have. Essentially, it reduces the level of interference which could cause the EDID information to be lost before reaching the PC. This is more noticeable when using a long cable, so this could be due to the lack of the ferrite core. However, the adapter listed in my previous post should rectify the resolution issue (though, it would still be listed as a generic PnP monitor).
I would weigh the cost of a cable with the ferrite core against the cost of getting an EDID emulator and select the cheaper option. I know an EDID emulator will rectify this issue, but I cannot say that getting a cable with the ferrite core will correct this issue with 100% certainty. I do know not having a ferrite core can cause signal quality issues. If you can still exchange the cables, then that may be the cheaper option.
Let me know what happens.

Streaming to TV using VGA cable questions!

I've been streaming my mid 2009 Macbook pro to my LCD TV for years now. For some reason in around Feb. 2012 it just stopped working. I'm using a VGA cable with a seperate audio cable. Anyone else have this happen? For some reason I think it stopped working after a software update around the time that the troubles started. Anyone have any idea? Trouble shooting suggestions? Anything helps, thanks.

Only HDMI will carry the Aduio and Video together, if you use VGA, a audio cable is still required in the headphone jack to carry the sound to the TV.

Battery Questions and RAM problems in TP S531

Hey there,
I got my first Thinkpad (S531) about a month ago and the good news is I really like working with a Thinkpad. However, there are a few things and issues that reading the forums did not yet solve.
First a bit of technical info about my system:
Model: Thinkpad S531
OS: Win 8.1 (self-install)
CPU: Intel Core i5 3337U @1.8Ghz
RAM: 6 GB (2GB+4GB)
GPU: AMD Radeon HD8670M (+Intel HD Graphics 4000)
1) Battery Life.
I know there are plenty of posts about this but I have a quite specific question all the forum posts I found couldn't answer: Does the battery at the point where the power level reaches 100% stop charging and power is taken only from the power connenctor? If so, is there a way of only charging the battery up to about 80% and then start using only the connector for power supply?
2) RAM.
I bought my Thinkpad with 6GB RAM installed, a fixed 2 GB piece somewhere fixed on the motherboard and a 4GB piece in a normal RAM slot. Now, I know that this isn't ideal for dualchannelling, but that's got nothing to do with this problem. Rather it seems, that Windows only manages to access 2GB, according to what I read from the Task Manager (screenshot attached) What can I do to make all 6GB accessible?

Hello Ihateallfruit,
It sounds like you are concerned about the Standby Time increasing using your battery excessively. Here is some info about what the Standby Time indicates and why it keeps counting up when the device is asleep from the article named:
iOS: About standby and usage time
http://support.apple.com/kb/HT1805
View Standby to see the amount of time the device has been turned on since its last full charge, including the time the device has been asleep.
Here is another webpage that you can use to help optimize your settings to extend your battery life:

Lightroom to Photoshop questions and ACR problems

I have Lightroom 5 and Photoshop CS5.
I've been working between the two with no problem until recently.
When i move a photo from LR to PS5:
1. I get the message that "This version of LR may require Camera Raw Plug in version 8.5 for full compatibility. Please update...."
When i go into PS it says no updates available.
2.When I move the photo anyway from LR to PS5 the file is blurry. Slightly off definitely not the same.
Help
Thanks

Anyhow: Please look here: Re: Photos from Lightroom 5 to Photoshop CC (2014) and back...

Libvirtd: setup questions and permission problems

Hello,
i noticed that someone removed the section which states that the "user=" and "group=" parameters of the /etc/libvirt/qemu.conf should modified from the libvirt wiki page.
So i removed my qemu user and commented the "user=" and "group=" parameters from the /etc/libvirt/qemu.conf to keep up with newest changes.
But after this i can't start my virtual machines from the libvirt system session which i normally use. I always get the error: "Could not access KVM kernel module: Permission denied failed to initialize KVM: Permission denied"
If i add "user=root" in /etc/libvirt/qemu.conf and restart libvirtd.service i can start my virtual machines. But i think there must be a reason why someone removed this section from the wiki page.
Then i decided to test the user session, but i can't add storage or network in the user session, because i always get permission denied or operation permitted error messages. So i skipped further tests and decided to ask this here.
This is my work configuration:
- My user is in the kvm and in the wheel group
- Nothing commented out in the configuration files below /etc/libvirt
- I created the file "/etc/polkit-1/rules.d/49-org.libvirt.unix.manager.rules" with the content from the libvirt wiki page
- libvirtd.service is enabled
If you need more informations, please let me know.
Kind regards,
morlix

Welcome to the forums.
I don't know exactly why the wiki has been changed, or if there is a 'best way' of using libvirt. But FWIW, my past and current working setup is as follows:
- My user is in the users and libvirt groups (and no others)
- The uncommented lines in my qemu.conf file are:
user = "alphaniner"
group="libvirt"
- I have the rule 50-org.libvirt.unix.manage.rules :
polkit.addRule(function(action, subject) {
if (action.id == "org.libvirt.unix.manage" &&
subject.isInGroup("libvirt")) {
return polkit.Result.YES;
I'm pretty sure that covers it. I have no issues using the gui to add networks or storage including raw storage devices owned by root.

VGA cable external monitor

I have a 2010 27 iMac and an external 22 inch Viewsonic monitor.
1. The monitor and VGA cable are about 5 years old.
2. I have the correct mini display port to VGA adaptor from Apple.
3. The external monitor works, however, it works only after I try to turn it on 5 to 25 times.
Aggravating in the extreme.
Could this be a problem with a low-quality or old VGA cable?
Would a brand new (higher quality, if so what kind) VGA cable?
I read this could be a problem with a video card, but I presume my 2010 iMac has a good card.
In short, would a new VGA cable likely solve the problem?
Thanks.

Hi, Lil,
   What is the downside in connecting the monitor with DVI? Digital is better than analog for image quality anyway.
    That being said, I have tried VGA from my dock in the past, with no odd symptoms such as the ones you are describing. You certainly don't want to get stuck with a defective dock. Are you using the same cable to attach the monitor whether it be to the dock or direct?
                                                                        ZZ

When i connect my mac book pro to an external display using a VGA cable and adaptor, the external display splits into several different columns of the same screen overlapping one another. Does anybody have any ideas as to why this happens?

I have used different VGA to mini port adaptors, different VGA cables and connected them to different external monitors and prjectors but the same thing happens. I am starting to think there may be a problem with the macbook itself however, when i have used a HDMI lead and adaptor to external monitors the external display is fine.

i bought a mini DVI to HDMI convertor and a HDMI to VGA cable to connect my mac book pro to a tv but it doesn't work any one can help.

I would suggest looking into a Thunderbolt to HDMI connector. In this case, you may be able to use the TV as an external monitor. For this option, please confirm through additional research. I have not tested it personally.
You can also use an Apple TV, which connects with HDMI. In this case, you can use Airplay Mirroring. Not all Macs support Airplay Mirroring, so you need to check first. I have a Mid-2011 27" iMac, and it supports Airplay Mirroring. I don't use it often because my TV is in another room, but I just tried it and it worked. It had to change the screen resolution to work well, so I don't know if I would want to use it as my day to day monitor. http://support.apple.com/kb/ht5404

I also tried an HDMI cable and had the same issue.

you are probably seeing the extended display.. to see ur main display go to pefrences then display steeings and turn mirroring on.
this will display ur mbp main screen. good luck.

I am trying to hook my macbook pro to a projector, which has a VGA cable. I bought a VGA to HDMI adapter, but whenever I hook it up, the screen on my macbook just goes black and I can't make it do anything else or even show up on the projector.

My laptop is still on; it just has a black screen that I can't get rid of without shutting down the computer by holding the power button.

Hey there lynmrigg,
It sounds like have an HDMI to VGA adapter connecting your MacBook Pro and your projector but the screen on your computer goes black and no image appears on the projector. I would use the troubleshooting in the following article to help resolve or isolate the issue here, named:
Apple computers: Troubleshooting issues with video on internal or external displays
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

You need to ask Apple to reset your security questions; ways of contacting them include clicking here and picking a method for your country, phoning AppleCare and asking for the Account Security team, and filling out and submitting this form.

I no longer have access to the back up email address I used when I set up my apple ID. I have since forgotten the answers to my security questions and am having a problem making changes to my account. What can I do?

HT204053 i want to change my icloud id on my iPhone, but it won't let me now that i have upgraded. I no longer have the password and the problem is It is using an old id which the email isn't valid and the security question does not think my birthday is

I want to change my icloud id on my iPhone, but it won't let me now that i have upgraded. I no longer have the password and the problem is It is using an old id which the email isn't valid and the security question does not think my birthday is valid. I cannnot delete the account because "find my iphone" wants the password linked to this old account. But when i go into the find my iphone app it is using my corect Apple ID. How do i fix this?

If you still have access to your old email address, go to https//appleid.apple.com, click Manage my Apple ID and sign in with your iCloud ID. Tap edit next to the primary email account, tap Edit, change it back to your old email account and verify it. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPhone on your device. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https//appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. You can now go to Settings>iCloud and sign in with your correct iCloud ID and password.
If you don't have access to your old email address, you will have to contact Apple to have them reset the password so you can disable Find My iPhone and sign into your iCloud account. You can either go to https://expresslane.apple.com, select "More Products and Services", then "Apple ID", then on the next page select "Other Apple ID Topics", then "Lost or forgotten Apple ID password" and click "Continue"; or you can contact Apple Support (http://www.apple.com/support/icloud/contact/).
