Connecting a MacBook to a TV issues

Hi, this is my first message here, so hello everyone.
I'm trying to connect my MB to a classic CRT TV (Loewe Nemos 32) using an Apple miniDVI to VGA adapter and a VGA to SCART cable.
I've tried every single resolution and frequency but the display sometimes is wrong, and sometimes doesn't work at all.
With some configurations I just get to see the scren on the TV in black and some window in a strange green, and the image looks stretched.
Has anyone experienced the same problem? Is there any compatibility issue with the miniDVI to VGA adapter? Anyone has worked it out? I've been searching thru the forum and couldn't find answers.
Thanx to everione willing to help.
MacBook 1,83 Ghz 1GB Mac OS X (10.4.7)

You need the mini dvi to Video adapter then a composite 'RCA' -to-scart cable. Connecting VGA to TV is not straightforward-a quite sophisticated circuit is needed not just a cable. This is the Apple store bit http://store.apple.com/Apple/WebObjects/ukstore.woa/6474042/wo/O55rX48EH3ak2LcWL AsxZS82oC0/13.PSLID?mco=1640190E&nplm=M9319

I don't understand how to fix this and I don't seem to understand where the problem is coming from.

Let's try the simple approach first. Restart your router. Any change?

MacBook Air intermittently has issues connecting to websites when wireless shows connected to the internet. The pages show that I am offline, but I can ping Google DNS. Windows PC, iPhone and Android phone have no issue displaying the same web pages.

Go step by step and test.
1. Power off the router. Unplug it from the wall. Wait a while.
    Plug it back to the wall. Power the router on. Wait until all the lights are lit properly. It will take a while.
    Restart the computer.
    Start up in Safe Mode.

    Checkmark the box for "Show Develop menu in menu bar".
    Develop menu will appear in the Safari menu bar.
    Click Develop and select "Empty Caches" from the dropdown.

Macbook Pro cannot connect to Internet via Ethernet / Cosmetic Issues

My Wireless Router died last night, so I connected my PC Desktop directly to the Modem. It worked like a charm.
I then decided to connect my MacBook Pro (2.4GHZ, OS X 10.5.3) to the Modem and...it didn't work. I tried going into the network settings (turning off the AirPort Card, moving the Ethernet to the top of the list, etc.) and I still could not get it to work.
Aside from taking it in, is there anything that I can do to try to remedy the situation, maybe a setting that I've missed? Also, there is a tiny ding on front of the bottom case. Can I get it fixed if I have the "Accidental Insurance?"

Was the MBP working when you had the router?
Also, did you power cycle the modem when you switched machines? Most cable modems remember the ethernet MAC address of the computer that was last connected to it, and will not permit another machine to connect until the unit is fully power cycled (turned off and back on). This is to enforce network provider policies of one computer at a time per account. (Most ISPs want extra money for extra machines.) The reason you can use multiple machines with a router is because the router performs some special functions to make multiple machines appear as a single machine to the outside world.

Can someone tell me how to connect my MacBook directly to my DSL cable modems BYPASSING by wireless connection?SING

Hi all. Can someone tell me how connect my MacBook directly to my DSL cable modem bypassing my wireless connection? thanks in advance.
(the Maverick upload that was pushed out last month will not load for me -- keeps starting and stopping. just read a review where someone had the same issue and once they bypassed their wireless connection, it worked just fine.)

I cannot connect my MacBook to LG Smart TV

I cannot connect my MacBook (13-inch Late 2007) to LG Smart TV (47LB730V) via "mini-DVI to HDMI" cable.
TV says that something is connected to HDMI input and then show "No Signal" message.
But when I connect my Mac with the same cable and settings to another display (to DVI or HDMI input) everything works fine.
I think I should place something to "system\libraries\displays\overrides" folder, but do not know what

HT1338 cannot connect my MacBook Air to a projector -does not detect and 2nd monitor. I have a new Mini port to VGA cable made by apple. When I read online I see that many people have the same problem - Is this an Apple defect??????????????????

I cannot connect my MacBook Air to a projector - It will not detect a 2nd monitor or display. I am using an Apple made Mini Display port to VGA adapter. As I read online I see that many other peple are having the same problem. Is this an Apple defect!!???? If so it just burst the bubble about how great macs are. I never had a problem with that on a PC. I hope I am wrong. What can you tell me?

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

Connecting my MacBook Pro (early 2011) to my Sony LCD TV (KDL-46XBR6) and listening to Multichannel surround sound.

Dear all,
I am attempting to connect my MacBook Pro (early 2011) to my Sony LCD TV (KDL-46XBR6) via the Mini DisplayPort to HDMI. I have successfully connected the two devices and can select "SONY TV XV" in the sound preference pane. I can see and hear what I'd like, however, I can only monitor the sound in 2 channel stereo. I have my TV connected to a Sony 7.1 audio receiver via an optical cable and can monitor 7.1 sound via other sources (Blu-ray, broadcast, etc). When I go into the Audio Midi Setup utility, I am unable to configure my speakers to be anything but 2 channel stereo. I am given the options for "2ch-16bit", "2ch-20bit", "2ch-24bit" and "Encoded Digital Audio". When I select "Encoded Digital Audio", my output automatically changes to Built-in Output. Has anyone been able to successfully resolve this issue? Thanks for all your help!

You should also ask this in the MacBook Pro forum. This is the forum for the 13” white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

I have tested it with the Moshi (http://store.apple.com/us/product/H1824ZM/A/moshi-mini-dp-to-hdmi-adapter-with-a udio-support) and Belkin (http://store.apple.com/us/product/HA342ZM/A/belkin-mini-displayport-to-hdmi-adap ter) adapters, both purchased from the Apple Store with no such luck. Have you or anyone else had success with any other third-party adapters?

Problems connecting my MacBook Pro to an external monitor

For the past 2 years, I have regularly connected my MacBook Pro to an external monitor (Dell SR2320L) using a VGA cable. When I do so, the picture automatically comes up in the maximum resolution of the external monitor (1920 x 1080). However, just in the past few weeks, the picture on my external monitor automatically comes up in 1600 x 1200 instead. When I click on the display menu in the upper right corner of my screen, there isn't even an option for 1920 x 1080 anymore. I've tried restarting my computer and even unplugging and replugging in the cable, but nothing seems to fix the problem. However, on at least some occasions, the problem seems to fix itself after about a day or so of use, and the picture reverts back to 1920 x 1080. I should note a couple of things: when I connect another MacBook to my monitor, the display automatically comes up in 1920 x 1080. And when I connect my Macbook to a different display, I have the same problem as I have with my display. So I think the issue is definitely with my computer, not my monitor. Does anyone have a suggestion about how to solve this problem? Or, when the problem arises, is there anything I can do to reset the display to 1920 x 1080 other than waiting for the problem to fix itself? Any suggestions woudl be greatly appreciated!

"No Signal" on my Samsung TV when trying to connect my MacBook Pro

When I try to connect my MacBook Pro to my Samsung HDTV it says no signal. My Pro doesn't flash blue or anything. I'm using a rocketfish adapter with an HDMI cable connected to it. I got my Pro in June 2010. Any idea on how to get this to work?

Hello TT31,
A quick fix you might attempt would be making visible, then clicking, the 'Detect Displays' button in the Displays pane of System Preferences. It can be made visible by holding the Option key once you've brought up the Displays pane (it will appear at the bottom right near the question mark).

If that doesn't get things working, I'd recommend taking a look through the following article, as it provides a whole host of useful troubleshooting steps for just such a situation.

I cannot connect my iPhone 4S to my home wifi. When trying to connect it says I have the wrong password, but I can connect my MacBook to the same network with the same password. I have tried to restart my router, reset my network settings, fail!

Hello, I am having some major troubles connecting my iPhone 4S to my home wifi. When I try to connect on my phone, it says I have an incorrect password. That's not possible because I can connect my MacBook to the same network with the same password. I have reset my network settings on my phone, reset my router, called apple support, triple checked I was trying it in correctly, I have no clue what's going on.
The only thing different is I just moved, but I have the same router/phone/internet provider.
I've seen some discussions of router security options being the problem, I have my router connected to : WPA-PSK [TKIP] + WPA2-PSK [AES].
The other options are: WEP , WPA-PSK[TKIP] , WPA2-PSK [AES] , WPA/WPA2 Enterprise.
My troubleshooting and understanding of all this is pretty limited, my applecare service did not help, please can anyone help me?
Thanks!

If the issue happened after an update, you may want to go into an Apple Store. Be sure to let them know exactly what's wrong with the device.

What is the best way to connect a MacBook Pro to my HiFi system ?

Hi,
I'm new to Apple support communities having just bought my first Macbook Pro (a 17" 2.5GHz i7 model) and this is my very first community post.
Im a bit of a Hi-Fi enthusiast, so, with my new MacBook Pro I've taken the opportunity of completely reloading my iTunes library in high quality Apple Lossless format. Took a while but now I've completed the task Im pleased I've done it.
My question is, what is the best way to connect a Macbook Pro to a high quality Hi-Fi preamp - my Hi-fi system is musical Fidelity, and the pre amp (an A5 CR Pre amp) and this pre amp, which has superb audio quality, only has analogue phono inputs ?
I'm interested to understand what both the wired and wireless connection options are. I'm guessing one option must be to use the headphone output, but I have no idea if the output from the headphone socket on my new macbook (which is presumably designed to drive headphones) would be at a suitable level for a phono line level input ?
Ive also read a few comments about using digital connection - and my second question would be - what is the audio digital connection on my macbook ?
Aplogies if this question has been asked lots of times before but I've looked through some previous posts and can't find any answers in simple and straightforward language concentrating on the issue of connecting a MacBook Pro to an analogue phono pre amp input ?
Thanks in anticipation of some advice.

What is the best way to connect a MacBook Pro to my HiFi system?
Look at the back of the reciever and see what your connection options are, the front headphone jack is output usually.
The Mac's analog audio in/out ports doubles as a optical in/out ports.
The analog won't over power your amp, it's just a headphonejack, like a powered mic, just enough power to get the signal to the destination in one piece.
Since you have a analog amp, your stuck with inferior analog connections, however you mentioned you wish to listen to the best sound quality of your lossless music.
To do that your going to need a decent surround sound system with Toslink optical import jacks, a Toslink stereo jack to regular Toslink adapter, Toslink cable and enable the optical output in your System Preferences >Sound
Another method is to use a Airport Express, it also has duo analog/opical out port. Then set up the Airport Express for iTunes streaming using the Airport Utility, then in iTunes setup the lower right corner one can set the connection.
I recommned a Harmon Kardon surround sound system, with their 100 watt satelight speakers and the 200 watt subwoofer. Enable the "concert hall" and other neat effects which will turn your 2.0 (stereo) iTunes music into 4 channel speaker sound filling the room with music and sending the lower channels to the subwoofer.
It will likely bring tears to your eyes that you can actually hear the full quality of your music as intended, I almost quarranty you will never want listen to music on a crappy iPhone or iPod again.
If a surround sound system is out of your budget, you can get by using the Harmon Kardon "Go Play" portable stereo and a analog stereo cable.
If your going to use your analog amp to power reference speakers, then there are various analog adapters of all sorts to make the appropriate connections once you know what they are, check out Radio Shack online for them.
