Help! Syncmaster 1100 blurry when connected to Imac with Mini DVI to Vga

Hi,
I recently tried to use my Samsung SyncMaster 1100 (21") as a secondary display But when I connect it with the mini dvi to vga adapter to my imac the image looks blurry. Is there some compatibility isue with syncmaster 1100?
Please Help!, I tryed the imac with a different secondary monitor and it works fine. I tested my syncmaster with another pc and it works fine. I don't know what else to do.
Thanks in advance

Hi Josh,
To start, it is considered extremely impolite to type in all capital letters as you have done. Please use all lower case, or preferably properly capitalised text, in future.
With regards to the problem you're having.. the reason you only see the desktop background is due to screen spanning. If you want the external display to display the same thing as the internal display, go to the displays system preferences pane, and check the box that says "Mirroring"
The color problem is probably due to a loose connection somewhere, either between the iMac and its adaptor, the adaptor and the cable to the projector, or between the projector and the cable plugging into it. If you're still having problems, try different adaptor cables, or try plugging it into a different monitor to try to work out which one is causing a problem.
Good luck

My wife received a new iPad Mini for Christmas-- when connected to iMac, icon appears in iPhoto sidebar; however, there appears to be no option to "unmount." Also, unlike my iPhone 4S whose icon appears in iTunes sidebar, the Mini does not. Any insights?

First open iTunes (version 11). Then connect the iPad. Now is it recognized?
If not .............

How to resolve this error....

I was resolve this error by my self.
We can handle this error with registering our current IP and host name on /etc/hosts.
example:
content of /etc/hosts:
127.0.0.1 localhost
127.0.1.1 myhost.workgroup
The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
added the ip and host name to be like this configuration
127.0.0.1 localhost
127.0.1.1 myhost.workgroup
172.20.17.74 myhost
The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback

Re: Not getting audio from TV when connecting MacBook Pro with all correct cables.

How do I get audio from the TV when connecting MacBook Pro with all the correct cables?

Hi Lynn,
If you're positive you have the correct cables, and positive they work, they must be plugged into an input on the TV made for that purpose, then that input must be selected on the TV's menu.

Mini-DVI to VGA - online video freezes when dragged from MacBook to LCD TV

I connected my MacBook to my LCD TV this morning via Mini-DVI to VGA, and am trying to stream online video. The video works fine when the browser is on my MacBook screen, but when I drag it over to the LCD TV, the video freezes. I tried setting the screens to mirrored as well, and the video wouldn't play (on either). I'm not really sure what else to try. Any help would be appreciated!

Try this...
With the TV connected, go into Displays Preferences and click on the Arrangement tab. You should see two blue rectangles meant to represent the two screens. One of the rectangles will have a white bar across the top, meant to represent the menu bar. Drag the small white bar from one blue rectangle to the other. This will move the real menu bar to the TV, making it the primary display. Now see if your video will play on the TV.

IMac Adapter Out Questions (Mini-DVI to VGA)

Hi everyone,
I've got a 2.4ghz C2D 24" iMac. For two years I had the iMac hooked up to my LCD tv via this route: iMac -> Mini-DVI-to-VGA adapter -> 75' VGA Cable -> LCD TV. I recently upgraded my TV, and no longer have a VGA port on the TV. I'm not looking to replace any cables because it's quite costly, and at this point in my life I'm not willing to spend that much to replace the setup.
My new TV has a DVI-D port on it. This is a very random connection, and yes, it is DVI-D (NOT DVI-I or DVI-A). What I'm wondering is if I get another adapter, a DVI-D male to VGA female adapter, will the iMac recognize the TV? I'm not sure how the video card treats the exterior Apple Mini-DVI to VGA adapter and am wondering if a simple $5 adapter will suffice.
Any help or information regarding this would be great.

That is a common adapter and it works, but the way it works is digital-to-analog. In other words, you plug the male DVI end into your computer and the female VGA end into the VGA cable (which then goes to your monitor/TV/whatever). Unfortunately it would not work if you went DVI(Mac)-to VGA cable-to DVI(TV) because it cannot convert the analog signal back into digital.
Those adapters are handy to have anyway so you could always buy one and try it out, but I'm sure you'll just get a blank screen (or the dreaded "no signal" message). Sorry

How to connect Macbook to TV through Dvi to VGA adapter.

I recently got s Macbook and was wondering how to connect it to my 32 inch sony tv. I have the dvi to vga adapter and recently bought an adapter that converts the VGA into RGA adapters + S video (all of which my tv has) When I connect the TV with these components nothing happens. I am curious to know what the next steps are to getting the Macbook to recognize the tv and how to produce an image on my TV. Any input would be helpful

what plugs do you really have.. that was confusing? This is a Macbook (not pro)?
First, it could be as simple as going to System Preferences|Displays| and choose to "Detect Display". It may not be recognizing you plugged something in.
If you want to connect you should probably get the proper Apple mini-dvi adapters to match exactly what your TV has. I use the adapter from mini-DVI-to-DVI with my DVI-ready TV and it works great. They have one adapter for mini-DVI-to-VGA, and one from mini-DVI-to-Svideo. Note that multiple adapters assume you have 100% compatible input when often adapters "cheat" on the actual output side... data and signals are probably not getting thru... your Mac can't recognize the TV as connected.
If you want to live dangerously, you might try using the mini-to-DVI adapter with a DVI-HDMI cable (single cable, no adapter) and see if that works (HDMI is a legit DVI spec so it should work, it works in reverse for my DVD player to TV connection)

Problems with the mini DVI to VGA connection

Hi I have a macbook, when I connect to the projector the screen is unconfigured and not projected properly keynote presentations. I Probed change the cable adapter mini dvi to vga but the result is the same.

Hi Robert, I cannot answer for you, as I have the same problem, which only came to light yesterday.
The same problem is discussed in the MacBook Pro community and none of the solutions there has solved the problem for me. Maybe one of them will for you. The link to this other set of problems is:

What is the correct adapter to connect my Macbook pro with mini-dvi to my TV with Scart

I have a MacBook Pro with mini-DVI and I want to connect it to my TV which has only a scart thing.
Can I use the mini-DVI to Video-Adapter and then a Video to Scart-Adapter?
Thanks for your help!

So of course you've corrected the title : "What is the right PLUG to connect my macbook pro to my TV ?"
OK so a bit more info : my TV is a Sony Trinitron TV.
It has the yellow/red/white plugs. I don't believe it has anything more sophisticated or recent than that.
Thanks for your help !
