External monitor dropping in and out

Hi all,
Just recently bought a new MBP 13" and up until yesterday bootcamp was working fine through a thunderbolt to vga cable,
It will constantly flick to black and then back to my screen and then black again about 3 times every 5 seconds
As you could understand this is really frustrating,
I have tried updating drivers rolling them back etc and have had no luck have tested cables and they work fine on my girlfriend's mac and on my mac when running mac OSX
any one got the same issue or know how to resolve?

Welcome to the forum!
Your story - complete with the pictures - sounds like a nVidia on its way out. You might have quite a bit of time before the analog (VGA) channel dies as well, though.
Good luck.
Cheers,
George

Using external monitor in bios and bootup on 3000 N100

Is it possible to use an external monitor in bios and bootup as my monitor has just died and is now out of warrenty? I am able to use the laptop monitor for about a second each time i open the lid before it turns off. Any help would be much appreciated.

thanks for the quick reply, however it did not work. would the monitor that im using make any difference? (its a sony multiscan g220)

I use a Canon VIXIA HFM41 camera with bluetooth WM-V1 mic and receiver. Audio drops in and out.

Trying to figure out why my audio kept dropping in and out while recording a 90 minute presentation this past weekend.
I just recorded 90 mins today in my office of a TV monitor screen and audio - no audio problems. Batteries were fresh and camera was fully charged over the weekend before I had the audio problems. Bluetooth? Could there have been some sort of cellphone interference with the bluetooth audio signal that caused the problem? I was with a group of about 25 people when recording the event - and I was the only person recording video/audio. My camera was about 15-20 feet from the microphone, which was close to the house mic and sound system - but no interference at all with the audio I did capture.
The audio didn't just drop out - it faded out, and would fade back in after several minutes. Video was complete, no interruption or distortion. HELP!

Yes, you can use the 85 watt adaptor. You cannot use the new adaptors because your computer is not equipped with the proper MagSafe connector. But you can use the older MBP adaptors as well as a 60 watt replacement adaptor. All can be found at Apple's Online Store.

Trouble with audio dropping in and out?

I had this problem for ages.
Apple TV3 was connected to monitor via HDMI. Monitor audio out was connected to hifi system. The audio was dropping in and out. Fix was to go in the monitor settings and set the HDMI audio to 2.0
Hope this helps someone, as I couldn't find this info anywhere on the net.

an update, switched the G4 laptop out with a G5 tower, keeping the rest of the setup the same, and the music played fine. Switched back to my laptop and the music played choppy. Noticed the CPU was bouncing around quite a bit on the laptop while playing music and that is when the music would cut out. So must be my laptop? Weird as the laptop worked fine for years and that is when it only had 512MB RAM. I did just update the laptop to 10.5 from 10.4 so perhaps 10.5 is the problem?
However I am running Twonhy Media Server on the laptop to stream video from the same server the music is on. I stream it to a PS3 and it streams perfect.
I would seem that iTunes does not efficiently stream music via mounted servers?

Why is it that when I plug my Macbook Pro to an external monitor, the external monitor turns black and shows the mouse only

Hi, yes preferences sees there is a second display it recognises what make of monitor it is etc but I just get a blank blue screen on the monitor when I change it to the hdmi setting! I have tried with mirroring on and off, rearranging the displays in the preference window and lots of different resolution settings but with no difference.
An old MacBook connects fine so the monitor and hdmi port must be okay. I'm sure we have used the cable before but it could have been with the previous MacBook Air. The current one I'm using is a mid 2011 version running lion and is (according to software update) all up to date.
Any thoughts or help would be appreciated!

Can anyone please tell me what I can do to fix the following problem....I updated the software to ios 5.1 two days ago and since then my network coverage drops in and out. Very difficult to make recieve calls with this happening every few seconds and near impossible to use the Internet. I have contacted support but got no support as 90 days had just ended. I have researched this problem all over the Internet and am now aware that I am not the only one with this problem after the upgrade. I have reset many times and read every post and still there are no answers...Can anyone please help? I'm trying to run a business and it's impossible with the phone doing this now.

I have been having the same issue for the last two weeks. No real indication as to why it ever began other than I had turned off my router and Airport Extreme Base Station off for a weekend while I was away from my place.
iPad, iPhone, iPod Touch, all have no issues at all with my Airport Extreme Base Station. Can stay connected throughout my living room, bathroom, bedroom, no issues whatsoever.
My 5 month old MacBook Pro 2.66 GHz Core i7 Airport is sometimes perfect, able to connect, DHCP, and browse without issue. Then, for no reason, I won't be able to join my wireless network, or when I can join, I can't pick up an IP address. And then it will connect, pick up and IP, and then it won't browse. No real rhyme or reason to when this will happen, or when it works.
I thought that it was an issue with my MacBook Pro, but then my sister visited with her brand new MacBook Pro 2.26 Intel Core 2 Duo, and while a month ago she was able to connect, DHCP, and browse without issue, this weekend she had all of the same issues I was having.
My XBOX 360 and MacBook Pro have absolutely no issues with the wired connection. Only my WAN seems to have this issue.
Did you ever find anything more to this?

why does my wifi drop in and out on my 3gs ?

Power cycle the Wi-Fi router.
Settings > General > Reset > Reset Network Settings.
Does the issue still occur?
If so, try a restore as new.
If it still continues, you may have a hardware issue. Take it to Apple for evaluation.

Audio dropping in and out on Express

My setup:
- Airpot Express running 6.3 software hardwired into my network gigabit switch. Stereo analog audio output plugged into my home theater system. Airport is setup to "Create a wireless network"
- Airport Extreme 802.11g running 5.5.1 software hardwired into my network gigabit switch. Airport Extreme is setup to "Create a wireless network"
- G4 Laptop with 1GB RAM running Leopard 10.5.8 hardwired into my network gigabit switch. Itunes 9.03 open with shared server mounted (see NAS drive below).
- NAS drive hosting 20GB worth of music (mostly high quality AAC files) that iTunes plays back from hardwired into my network gigabit switch.
My Airport Express was streaming audio fine (using the Remote application on my iPhone) however within the last 4 or 5 months music has been playing back choppy dropping in and out every 5-10 seconds or so for about a half a second. Does not matter what music I am playing. Cannot get iTunes to output audio locally on my laptop (only via Express) so think there is something going on.
I know the Airport Extreme basestation probably has nothing to do with the problem but just wanted to point out the fact that I have configured both the Airport Extreme basestation and Airport express to "Create there own wireless networks". I could never successfully include the Airport Express into the Airport Extreme wireless network so kept them separate. However this should all be a null point as the Airport Extreme is hardwired and should not be using any wireless functionality for streaming the music.
Any thoughts?

an update, switched the G4 laptop out with a G5 tower, keeping the rest of the setup the same, and the music played fine. Switched back to my laptop and the music played choppy. Noticed the CPU was bouncing around quite a bit on the laptop while playing music and that is when the music would cut out. So must be my laptop?

Why does my Iphone 4S drop in and out of charging?

Every time I charge my phone it drops in and out of charge. Can someone help me.......

Yes, as paulcb says, it's most likely because coverage inside the building stinks. You're lucky you can get the EDGE signal inside. The last place I worked, AT&T had to come out and place an antenna inside the building. Largely because we threatened to cancel our contract of over 500 phones with them if they didn't fix it.

VGA adapter splitter? 1 external monitor for desktop and macbook

I recently bought the Apple VGA adapter and it works great with my macbook and external monitor. However I use that same external monitor with my desktop PC. It's becoming a pain to constantly unscrew and plug out the VGA cable. So I'm trying to find a VGA splitter that has 2 male ends and 1 female end, but I'm not sure if something like that even exists. Basically I want to be able to use my external monitor with my macbook and pc without having to unplug the monitor's vga cable from my desktop. If anyone can give any suggestions that'd be great. Thanks!

You shouldn't try a splitter cable as you would have interference from the two signals. You need a VGA switch box like one of these.

T500 XP 32 - 2 external monitors - one in VGA-out & one in DisplayPort ? (1920x1080 & 1280x1024)

I searched and found some information... but the information wasn't specifically clear, so better to find out for sure, and help archive some clear information for the community...
I'm looking at attaching 2 external LCD monitors to my T500 (2082-3HU). OS is XP 32bit.
One will be a 19" 1280x1024,    and the other will be a 27" 1920x1080.
Plan is to connect 1 to the VGA-out and 1 to the DisplayPort.
First.. will this work?
Second.. which is better to attach to which port? (and why?
and
Third.. what are the maximum resolutions that the VGA and DIsplayport ports can provide?   Does it matter if it's VGA or DVI?
I was going to get a USB to video adapter for $50+, and then remembered the DisplayPort!    If it will work, it's a great way to save some money, get much better video res. and speed, and keep a USB port free.

Here are two posts I found ... (they appeared out of no-where)
you can connect two external WUXGA (1920x1200) monitors to the T500 using both the VGA and displayport connectors.   no other hardware is needed besides the display cables.

I connected 2 external monitors (1 thru Displayport , 1 thru VGA port ), and it works fine, its very easy to configure it using Lenovo Presentation utility.
But now I have the view only on those 2 external monitors (notebook display is off)

and for any more monitors, a USB-VGA, or USB-DVI adapter can be used... from lenovo, or EVGA or any other good type.
DisplayPort can support, at least, 2500x1600

use a Lenovo usb2dvi converter and the displayport to dvi converter.
This will allow you to use 2 external WUXGA monitor. If you need to support more WUXGA monitors, then you just need to get more Lenovo usb2dvi converter, up to a maximum of 6 (maybe slightly less i can't remember) using the integrated gpu.

My external monitor flickers intermittently and wont function when connected to macbook pro

Hello everyone,
I recently purchased a cable to convert the thunderbolt/miniport to the VGA input on an external monitor I have had laying around for a few years. I am currently running osx 10.7.5 on a macbook pro.
When I plugged the cable to connect my macbook to the monitor, the monitor certainly recognized the cable, but the display would not do more than flicker in and out intermittently when connected to my macbook.
I have searched the forums for a solution to this, but haven't been able to find one that works. I tried resetting the SMC and restarting while holding cmd+P+R but none of these "fixes" seemed to help.

Simplest thing to try is a PRAM reset.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Dealing with dropped frames and out of sync audio

Hi!
I'm using Final Cut Studio 3 and I'm trying to record some video from a pretty old MiniDV-camera. The problem is that a have some dropped frames and when I record the whole thing it gets out of sync.
By default Final Cut aborts the capture (without saving) when it finds dropped frames. That won't work for me. I start recording, it records a couple of minutes and then it just aborts without saving anything.
I tried to record the entire tape when using the option of not aborting on dropped frames. I recorded the entire video but not it gets more and more out of sync later and later in the video.
So, do you have any suggestions on how to deal with this? Maybe I can use an external application for this cause I haven't found a way to deal with this in Final cut.
Best
Felix

Hi(Bonjour)!
Did you shoot in DV or HDV ?
Did you try to capture HDV with Apple Intermediate Codec 1080i60 (or 50 for europe)?
Does you downconvert HDV shooted to DV upon capturing from camcorder ?
DV-NTSC 48 kHz is the way to go with downconverted material.
Does your DV audio setting is 16 bit on FX1 ? (HDV is a fixed one).

When playing iTunes from 2006 MacBook via Airport Express remote stereo speakers, the music keeps dropping in and out

I've tried hours and a trip to the Apple Store to resolve this problem, and no luck so far.
We have two Airport Expresses -- one is an older "g" version (from 2006), one is a newer "n" version (a couple of years old).
We have one older MacBook (from June 2006) (so it can only use "g" wireless and also cannot be upgraded to OS X 10.7 "Lion").
We have one MacBook Air and an iMac (both less than a year old), an iPad (about 2 months old), and a recently acquired AppleTV (in the past few weeks).
We also have two iPhones that do use our local wireless network on occassion.
We have stereo speakers that are currently connected into one of the Airport Expresses.
For years (until the past few weeks) I played music from iTunes on my first generation MacBook to the speakers with no problems (using the older "g" Airport Express). Recently, however, when playing music remotely over the speakers we have gotten fairly regular (though at random intervals) drops of the music in and out (drops are for a second or two each). So far, here's what we've tried to do:
(1)     Went to the Apple Store, where they thought the problem might be compatability between the g and n equipment in our house. They suggested that we get an Airport Extreme and use that as the base so that 2.5 GHz and 5 GHz networks could each be set up, allowing the two systems to play nicely. Spent a couple of hours setting everything up. No dice.
(2)     The skipping happens even when (a) I turn off the Apple TV; and/or (b) turn off the older Airport Express and just use the Extreme and the "n" Express (with the "n" Express as the connection to the stereo).
(3)      When I have the wireless network drop-down menu selected on my MacBook, the skipping occurs immediately after the computer is "looking for networks" (as shown at the top of the menu). The computer does this at random intervals on a regular basis. The skipping, however, will occur even if the menu is not selected.
(4)     Here's the weirdest part. The skipping has even occured when playing iTunes from our newish iMac, with the older MacBook shut down, with the older Airport Express shut down. In this case, the skipping only appears to occur when we have the wireless network drop-down menu selected and again, it occurs when the computer is "looking for networks" which occurs at random intervals. In this situation, the skipping only seems to occur when the menu is selected.
At this point, if I can't find another solution, I'm going to return the Airport Extreme, and just give up playing music over our stereo speakers from the MacBook (and instead transfer music to the iMac and play from it). But I thought I'd try a last-ditch effort to ask for help to see if anyone could figure out what might be causing the problem. I would chalk it up to the problems of using my old "g" network MacBook on a newer "n" system (though I'm not about to spend $1K+ to upgrade my laptop just for this), but for (4) above, which seems to indicate something else is going on.
Any help would be most appreciated!

Unfortunately, your description of the problem and the placement of both your main and AirPort Express routers does lend itself to believe the problem is most likely Wi-Fi interference. If it isn't the microwave or portable phones, it could be obstacles like walls between the routers that may be preventing the stream from consistently reaching the Express.
In your configuration, the stream will first travel to the main router, and then, from the main router to the AirPort Express. If, for example, you started the stream in the same room as the Express, that stream would have to travel across several rooms at least twice.
