DVI to s-video TV display

what I want to do: I want to be able to use my tv as a second display to watch movies on etc.
What I have: Macbook pro 15in with a DVI Out, DVI to s-video/ composite adapter.
RF modulator for the tv as it is an old tv with only coaxel in, the RF modulator has an s-video and composite in.
Ive tried hooking up the dvi to s_video adapter to the dvi port, the s-video cable to that converter then to the rf modualtor, the rf modulator is hooked up to the tv and is working properly. I tune the tv to channel 4 like i do for my ps2... no dice. when I hook my macbook pro up to my dvi monitor it auto detects is and displays. it does not do this however with my tv. I have tried testing displays and changing the resolution down to 800x600 AND lower, still no go. What do i need to do? does it involve the F7 button?? bc ive pushed it... infact i have no idea what that does, i thought it was a display button. guess not.

turns out the dvi to s-video converter was kinda sorta broke, I had to jam the cable down into the s-video and rca plastic piece, I guess it wasnt making a perfect condition. Oh well works now.

I am attempting to plug my mac into my tv. I am using the mini dvi to s video adapter. When I plug it in, the display goes all wonky and becomes stretched and enlarged.

When I attempt to connect my mac to the monitor using a mini dvi to s video adapter the display becomes enlarged and stretched. I cannot seem to fix this using the system preferences or the quick keys that allow you to zoom in on the display. Any suggestions?

I am using MAC OSx 10.5.8 (9L31a) as my operation system. The TV says "No signal. Check connected device's power, cable connection and source selection." Seems to me that that goes in hand with what the Samsung tech said about the Mac needing to be forces to use the external display. But how do I do that?

Mini DVI to S-video display problem

I connect my macbook to a plasma TV using mini DVI to S-video adapter so I can give keynote presentations. All of a sudden, having not changed any settings, the plasma display went to black & white while my macbook's display remains in color. I have checked with two different s-video cables and with another TV, as well as trying to change the color display in my system preferences, but after several hours have given up. Anyone else have this problem or have any thoughts on how to alleviate it? Thanks

A wire may have broken inside the mini DVI to S-video adapter. S-video uses one wire for the brightness, and one for the color information. If the color wire breaks you will get a black and white picture. Until Apple replaces the adapter, you could use the composite video output, but the picture will not be as sharp.

DVI to s-video adapter altering laptop display after connection with TV

Greetings,
I recently got my MacBook Pro to display on my TV via the dvi to s-video adapter (also connected stereo sound). Everything works great, but ... after I disconnect the windows on several of my programs are altered (stretched, shortened, often relocated offscreen or very near off-screen). My ical window refused to display at all. I trashed the ical preference file in the Library, restarted the program and I could see the window again. I'm going to be connecting with my TV a lot. It will be a pain to have to trash preferences files after every connect. Anyone know what's going on?
Thanks,

What happens if you quit all those applications prior to making the connection to the TV? I would think that should prevent the windows from dynamically resizing. But they are still going to have to resize if you open those apps while connected to the TV.
Mac OS is trying to keep the open windows completely on the desktop. Since your TV's screen is likely much smaller (in pixels) than the 1680 x 1050 pixels of the MBP, the windows are being shrunk and in some cases repositioned so they fit on the desktop when connected to the TV. Unfortunately, the previous settings are forgotten and not restored when you disconnect.

Not sure that I have selected the correct forum. Hope my questions are clearly stated.
Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter. TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices). It does not show Mail or Safari menus. System preferences' display "gathered" the Samsung and chose its resolution. I did not find a way to select the Samsung as my display.
In addition to having old hardware, we have Verizon FIOS providing internet and TV access. Is there any way to make this work for us? We would like to stream video (Netflix) and view shows from the Web. Do we need Apple TV to do this? Or is it not possible with our old iMac? My husband thinks that our Airport could be a factor.
Thank you

Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
There are, actually, many alternatives to choose from than just from a Mac.
You need to have or invest in a WiFi capable router for all of these examples.
Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
If you have a older Mac, like I have noticed many users do, then you have other options.
If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time, you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

Mini DVI to S-video and composite giving complete distorted output!!

I tried to hook up my 20" Sony Trinitron either through S-video or composite to the powerbook without any success. I got completely distorted picutre. I have tried all the video resolution setting that is available on the Displays reference window with the same result. Does anybody out there run into this problem at all.

I have a 12" PowerBook 1.5ghz and had the same problem with garbled video today. When I plugged in the Mini-DVI > Composite/S-Video adapter the PowerBook would consistently think it was attached to an ordinary VGA monitor, and could not sync with the television. This caused a B&W, warped, split in half picture.
I took the adapter back to the Apple store, plugged it into one of their demo units, and saw it behaved the same way. They gave me a replacement and everything has been fine since.

Mini-DVI to S-Video Adapter doesn't work

Hi, I am using the Mini-DVI to S-Video adapter from apple to connect my macbook to the TV. But the only thing I get is a grey flickering picture on my TV. When I click on the monitor-button I can see that my macbook detects only a monitor (but not a TV) in addition to the macbook-LCD-display. I tried all different resolutions, but needless to say it doesn't work.
Can the adapter be broken, or is there a problem with the macbook?
Macbook white 2 GHz Intel Core Duo 1GB RAM Mac OS X (10.4.8)

If you connect the Mini-DVI to S-Video adapter, the monitor button on the menubar should show resolutions for Color LCD in one section and NTSC/PAL in the other.
A grey flickering picture is indicative of picking the wrong standard-PAL vs. NTSC.

Mini-DVI to s-video: black bar on left side

Hi,
When outputting video through "the mini-DVI to s-video adapter" i have a black bar on the left side of my television.
It seems like the 1024*768 resolution is not able to completely fit the 4:3 area of my television (the image is to small).
any ideas?
thanks!

I'm absolutely sure everything is displaying and that the image is not deformed in any way.
So my conclusion is that the image is just smaller (in every dimension) than it should be and than it was before.
I will try a lower resolution later today.
thanks for your help and interest!

Mini DVI to S-Video B&W only!!

I bought a Mini DVI to S-Video adapter and a S-video to RCA cable to hook my MacBook up to my TV, but when I plug it in I can only see it in Black and White. I checked System Prefs>Displays and tried out several different profiles, to no avail. FWIW the audio seems to be fine.
What am I doing wrong? Thanks in advance for your assistance.

In my experience when you try to connect an s-video source to a TV you need the TV to be able to accept s-video signals or it does come out black and white.
One of my televisions has front inputs which consist of one s-video plus the standard three phonos. If i dont tell the tv its an s-video cable the image is black and white.I had the same kinda thing with an older tv when using a scart convertor which had s-video input. I had to use the correct scart socket which was the one that supported s-video and then tell the tv it was s-video by switching to AV2/S instead of just AV2.

Dynex mini-DVI to S-video adapter

I bought a Dynex mini-DVI to S-video adapter with my Macbook and I just tried to use it to plug into my projector via S-video. The resolution of my screen dropped to 800x600 but otherwise nothing happened. I even followed the Max OS X help information and turned on the computer with the adapter and cable plugged in and it still didn't display on the projector. I went to the display settings in system preferences and asked it to detect displays but I don't think it changed anything either. It seems the Dynex website is rather sparse on documentation and support. Any ideas? It'd be greatly appreciated!

I've tried pretty much everything with the same mini-DVI adapter made by Dynex.. if anyone can help it would be much appreciated!

DVI to S-video connector?

I'm looking at buying a cable to extend my display onto a TV. Apple sells the mini-DVI to S-video/Composite adapter but doesn't say if it works for the Powerbook G4 15". I would assume that if it works for the 12" it would also work for the 15" and 17" versions, but I'm looking for confirmation before I go spend $20 on it. The cable I'm thinking of can be found here:
http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=4D2 4B4AB&nplm=M9319G%2FA
I'm wary because many of the descriptions include the qualifier "ONLY" before naming the compatible systems.

You're absolutely right. I wasn't with my Powerbook when I asked this question, so in any event, I thought if the S-Video jack ever got damaged or malfunctioned, I would have a backup. Having the Powerbook in front of me now it definitely came with everything I'll need so I guess this was just a test post and now you get points for replying. I'll still need to buy one as a gift though. Thanks.

DVI to S-Video TV out no longer working

I have a Macbook Pro 2.4ghz Core 2 Duo, bought mid 2007. Up until December last year I have been able to use an Apple DVI to TV adapter to display on a TV. For some unknown reason this no longer works. To find a solution I have tried plugging things in different orders, deleting preferences, creating a new user but nothing works. It may have happened after a Mac OS X Leopard update but I cannot be sure.
What I do know is:
- the DVI port still functions on an LCD, using a DVI to VGA adapter or just straight DVI.
I've read about failing video cards etc but I don't think any of these apply to my model. I believe it might actually be a software issue...
Has anyone had any success with recent versions of Leopard and connecting a TV?
Thanks.

turns out the dvi to s-video converter was kinda sorta broke, I had to jam the cable down into the s-video and rca plastic piece, I guess it wasnt making a perfect condition. Oh well works now.

DVI to s-video adpater for Power Mac G4?

I'm attempting to view digitial photos on my Power Mac G4 on an HDTV with an s-video connection. I've tried Apple's "DVI to video adapter" for the Power Mac G5, but it doesn't work, even after clicking "Detect Displays".
Is there a DVI to s-video adapater from Apple or anybody else that will work with the Power Mac G4? If not, are there any other options?

The Apple DVI to Video converter only works with certain graphics cards. The card has to be able to generate interlaced video at the correct scan rate, and modulate the color onto a carrier signal. For other card you would need a scan converter like:

This device has a VGA input, so you might need a DVI to VGA adapter. There may be other devices available with DVI input.

DVI to S-Video not full screen!

I recently bought an Apple DVI to S-Video adapter and hooked it up to my 60" Hitachi 60SDX88AB rear projection TV. The picture looks fine, colorwise and all, but the picture does not take up the whole screen- there are 2 inch black bars on 3 sides of the screen. I played with it for an hour with no avail- changing the resolution only changed the aspect ratio within that same area, and checking "overscan" under Display Preferences made the picture take up more than the whole screen, cutting off, again, a couple inches on all sides.
I switched this setup to my 20" LCD TV in my bedroom thinking it may just be the monitor, but the same thing occurred, this time with bars on all 4 sides of the screen. How can I fix this?

No, unfortunately it doesn't. My only options with this older model are s-video, composite, and component. I don't have a DVI to component converter, and hooking it up with composite gives me the same issues.

DVI to component video - possible?

I'm trying to find a way to connect the DVI output of my MacBookPro 1.1 to the component video inputs of a Sony STR-DH810 receiver which is hooked up to my TV. I discovered I can't use the HDMI inputs on that receiver with an alternate audio source, which is why I'm trying component video. When I connect everything, I get no video - only audio. I know the component video inputs are good because they work with my DVD player component video outputs.
The owner's manual of the receiver says "display system must support component video (Y, Pr, Pb) signal output function in order for the image to display properly". Does my MacBookPro work this way?
I guess my other option might be to find a DVI to composite video cable, if such a thing exists?

Hi s,
I don't know that I've heard of successful DVI to component, but in theory it may work, as the GPU outputs both digital and analog signals.
OTOH, I've seen a number of reports that this works (S-Video or composite):
