VGA Display Detected But Has No Signal

Hello,
Here's the issue,
I'm working on a 13" MacbookPro 10.8. I plug in mac's "display port > VGA" adapter to display my second screen on projectors for a power point presentation. The Mac flashes the screen like it recognizes the display and when I go into the display settings it gives me the second screen options just as it should. However, the desplay remains black as if nothing was ever plugged in. I did the exact same thing on my personal computer which is a 15" MacbookPro 10.8.4 and the projector works fine ruling out any issues with the gear. I've gone to several forums and tried all of the "unplug this, turn this on, wait 15.5 seconds." tricks that people say to do but to no avail. I'm going to try to update the system to 10.8.4 and see if that works, just waiting on passwords since it is a work computer.
Any Ideas?
- Josh

It was the update! I guess 10.8 had some issues with the projector but all is well with 10.8.4

My iphone 5 is showing the network and 3G logos but has no signal bars and I cannot make or receive calls or use the internet

Hi,
I recently bought my iPhone5 second hand off a friend. Having inserted my sim the O2 network logo and 3G symbols appear in the top left although there is no signal registered. I am also unable to make or receive calls as well as use the mobile internet.
The phone is registered to O2 so there is no network clash

Hello denman1991,
It sounds like your phone is not connecting to the cellular provider network, and you are also unable to connect to the Wi-Fi network. I would recommend these troubleshooting steps from the article named:
iPhone: Troubleshooting issues making or receiving calls
https://support.apple.com/kb/TS3406
Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.
Check your phone settings:
Check your Do Not Disturb settings: Tap Settings > Do Not Disturb.
Check for any blocked phone numbers: Tap Settings > Phone > Blocked.
See if Call Forwarding is turned on: Tap Settings > Phone > Call Forwarding.
Ensure that your software is up to date:
Check for a carrier settings update.
Check for an iOS software update.
Note: Some updates may require a Wi-Fi connection.
If the iPhone has a SIM card, reseat the SIM card.
If the iPhone 4 or iPhone 4s is on the Verizon network, dial *228 from the iPhone and select option 2 to update the Preferred Roaming List (PRL). The PRL determines the cellular towers the phone uses for cellular service, selecting those with the best signal strength.
Reset the network settings: Tap Settings > General > Reset > Reset Network Settings.
Try to make or receive calls in another location.
Attempt to isolate to one network band:
If you're having the issue on LTE, disable LTE, if possible, and try again.
If you're having the issue on 3G/4G, disable 3G/4G, if possible, and try again.
Contact the carrier to check the following:
Your account is properly configured to use the specific iPhone that has the issue.
There are no localized service outages.
Your account doesn't have a billing-related block.
Your calls don't have errors on the carrier system.
Restore the phone as new.
Also, for your Wi-Fi network issues, I would recommend this article named:
iOS: Troubleshooting Wi-Fi networks and connections

Display not working, external display does, but blue screen when windows loads

Hi folks, wondering if anyone can help.
My DV6's display is no longer working. An external VGA display works, but when it gets to the "welcome" screen as it loads into windows, I get a blue screen. I was able to load into safe mode previously, but I foolishly reformatted and reinstalled windows thinking it might solve the problem. Now I can't even get into safe mode because it won't allow a first time setup of Windows in safe mode.
I suspect this may be the death of my loyal notebook, but was hoping someone could propose a solution.
Thanks!

HI @Mikep037,
Thank you for your query, I am happy to assist you!
I understand that you are having an issue with your display.
You have reformatted and reinstalled Windows but are unable to complete the setup.
Did you do a recovery or did you reinstall Windows from a retail disk?
First I would try a hard reset. HP Notebook PCs - Use Hard Reset to Resolve Hardware and Software Issues. Please be sure to remove any CD/DVD from tray and disconnect all externals devices or USB's.
HP Notebook PCs - Overview of How to Troubleshoot Problems When a Computer Does Not Start Up or Boot...
Here links to aid with the recovery process.

Imac does not detect external vga display

Please help with connecting external vga display to an imac 21.5'', late 2012, OS X 10.8.5 via Mini DisplayPort to VGA adapter.
I have connected an external monitor (Fujitsu Siemens) to the thunderbolt port of the imac using a Mini DisplayPort to VGA adapter. The imac does not detect the external monitor. I have followed all instructions and suggestions I could find at Apple Support Communities without success.
The monitor is in perfectly good working order as it has no problem connecting and performing flawlessly with a dell windows laptop. The imac, connected via the Mini DisplayPort to VGA adapter to the D-Sub connector of a Samsung smart TV, also worked perfectly.
To add insult to injury, occasionally, when restarting the iMac with the external vga display connected and powered on, the iMac screen starts intermittently turning blue for a brief second or so and resuming back to normal. The frequency of 'blueing' is once in 2-3 seconds. This particular rather disturbing problem, luckily ceases when the external display is switched off.
Any advice and help with resolving the above connection problems will be gratefully appreciated.
Thank you
ghogoh

I am having the same issue. Hope Apple can fix this soon!!!

MacBook pro Late 2011 detect external monitor but still not signal on it

Good day.
I have MBP 13" Late 2011
Processor 2.4 GHz Intel Core i5
Memory 4 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 384 MB
Software Mac OS X Lion 10.7.4 (11E53)
Mini display to DVI adaptor and Acer monitor conected with DVI cable

As you see it's detected by MBP but says "no signal". I tried all suggestions found here and anywere else but no solution still found. And of course i tried Detect Display and changing resolutions.
Is there any way to make it just work!?

I've just found out that my Macbook's Bluetooth spec is Bluetooth 2.0+EDR and my keyboard's Bluetooth is 3.0. Would this be of any issue?

Screen says "use tv as display" have vga out and tv has rca or s-video in can I?

I have old ze4935wm laptop with XP
Quick button properties screen says "use tv as display"
It only has vga out and tv only has rca or s-video in.
How can I do this?

I solved that problem.
If your tv also has component imputs- the red/ble/green cables that look like ordinary rca cables-
as a matter of fact you can use the regular rca audio/video cables, I do.
Tiger direct has an item called.PC2Tv.
It has a box- (size of a deck of cards) connect the vga wire from the box to your computer,
connect the usb wire from the box to your computer.
Then run the rca cables from the box to your tv.
It comes w/ a remote, you can adjust contrast, color, sharp & brightness, etc.
It's powered by your pc/laptop and cost about $20.
I use one on my patio where the rear projection tv has an hdmi input, but it doesn't work for computers-
the tv's manual says that the hdmi input is just for dvd players.
I also use one in my garage, where I have a crt tv.
Works perfect.

A new ipod has been detected but cannot be identified. [drivers?]

Yes -that again- the reason I'm making a new post is that this is the second time an ipod hasn't worked with me, I would like to know if there's something I can do to my system or whatever to repair it. Here's the situation.
- Just so ya know, I use Vista on a laptop [unfortunatley]
- Previously [as in yesterday] I had an ipod touch, it was stuck in recovery mode and nothing [and I mean nothing] worked to recover it, it wasn't being recognized at all. This problem occured when I installed Itunes 9.
- Today I bought myself a brand new iPod Nano (5th Gen) for several reasons [not just to do with the itouch breaking, I was sick to death of the thing in general], took it home and connected it. 'A new ipod has been detected but cannot be identified' yadda yadda.
- I tried everything, I have also downgraded my itunes back to 8, still the same message!! Argh! Here's the thing (that I think might be causing the problem) when I open Device Manager and go to Universal Serial Bus Controllers, there is no apple/ipod recognized. There is a 'USB Mass Storage Device' whch has an error symbol next to it, I've tired updating/reinstalling it etc and it doesn't work ):
- Is there anything anyone can do? I'm so sick of ipods breaking on me. Just so you guys know, I'm not completley computer savvy so i'll need precise instructions, thanks so much to anyone who can help me.

This is how it's displayed: http://i50.tinypic.com/nd7vk7.jpg
And this is what happens when I click properties and 'search for solutions': http://i47.tinypic.com/2iu3vrc.jpg (the box disappears after that, apparently having done nothing, when I search online for software it informs me my computer already has the best/latest installed)
I use a Toshiba Satelite L350-170, my Vista is a 32-bit Thankyou!

Display driver has stopped responding but has recovered ....

I have just rebuilt my system which is now
Windows 7 (64 bit)
Photoshop CS4 11.0.1 (64 bit) ( open GL)disabled in preferences)
Core I7 950
graphics card Gianward nividia gtx 285
Photoshop is installed on OCZ vertex SSD
File info on Western digital caviar black
Mother board ASUS rampage gene
I print to 3 printers incuding an Epson 7900
I am not having any problems till it comes to printing my photos ..
When I print to any of the printers with "print preview " enabled I get the message "display driver has stopped responding but has recovered ...."
The Microsoft event ID = 4101
The screen goes black and remains so for a few seconds before it returns ...
Sometimes I am able to get the printer to go ahead and print... sometimes it wont and I have to start the whole print process again..
Needless to say this is irritating ..( by the way this happens with both of my Epson Printers ..the other is an 3880
I have just downloaded the latest drivers for both printers and the latest Nvidia drivers ... the problem remains
The ASUS probe indicates that all teperatures are within an acceptable range..
I would be most gratefull if some one could help with a solution ?

It really depends on what drivers windows uses by default for you. On older versions (vista, xp, etc) it would default to Standard VGA driver which is there only for compatibility purposes so it's barely using the video card but if i remember correctly win7 tends to use drivers from ati/nvidia's site for video cards (not the latest version but still a major step up from Standard VGA).
See if you can enable OpenGL drawing in Photoshop. If you can and you don't get any funky stuff (broken cursors for the brush tool and the like) then there shouldn't be any problem with using those drivers.

ITunes message: an ipod has been detected but could not be identified properly.

For some reason my ipod nano 7th generation will not connect to iTunes anymore. It comes up on my computer but iTunes will not "identify" it. I have tried resetting my ipod and unistalling iTunes then reinstalling and following the help intructions online. Anyone know how to fix this? Cheers.

I recently began receiving this message when i try to sync my ipod to itunes: " an ipod has been detected but it could not be identified properly." Never had this problem before. Have tried all troubleshooting suggestions.
Doublechecking. Have you also tried a complete uninstall of both iTunes and all the other related software components and then a reinstall? If not, try the instructions from the following document:
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
