DVI to Video adapter settings - help!

Hi all...I just bought a DVI to Video adapter, and it was working fine, then I got stupid and started playing with the resolutions. All of a sudden, the TV will only display garbage on the screen, and/or a flipping picture with no color that I cannot get any details on to fix anything. I have reset everything I can think of - the NVRAM, PRAM, and even done the PMU. I have no idea what to do to get the thing to revert back to another state - one that was working before. It was originally set to 1024x768, then I lowered it to 800x600 for readability, then went lower. Then it screwed up. Any ideas would be great. Thanks in advance!

Try the procedure outlined here. If you have trouble with it, report back here for further advice.

MacBook connecting to Mini-DVI to Video Adapter problems- HELP!!!

I just purchased the mini-dvi to video adapter. Immediately upon connecting the device, it makes the connect sound, followed immediately by the disconnect sound, accompanied with a flashing black screen. This repeats until I remove the adapter. I just updated my graphics driver, but that didn't help. I'm running windows XP on a macbook purchased in august 2007. please help!

Does the adapter work if you're in OS X? If so, you may get better help over in the Boot Camp forum here:

Apple Mini DVI to Video Adapter is not working. Please Help...

I bought an Apple Mini DVI to Video Adapter to connect my Macbook to a TV using normal video cable. When I connect the cable, my Laptop DIsplay gives a flickr once and then it shows nothing. I checked Display in the system preference where I don't get a secondary monitor option. My TV is panasonic and it's an old one. I work on Final Cut Pro and it's very very important to see my videos on a TV. What am I doing wrong with the connection? Anyone Please Please help...

Your probably not doing anything wrong. There are thousands of users with Similar issues and it seems to be with many different adapters.
We have Mini DP to VGA (3 different brands) and they all fail most of the time. This seems more prevalent with LCD Projectors. I've tested some (50+) with VGA Monitor (HP) and they all worked, LCD Projector (Epson, Hitachi, and Sanyo) and they all fail, DLP Projector (Sanyo) and one worked.
My Apple Mini DP to DVi works most of the time. My Mini DP to HDMI (Generic non Apple) works every time.
The general consensus is that Apple broke something in the OS around 10.6.4 or 10.6.5 and its not yet fixed. As we are a school we have logged a case with the EDU Support group so will see what happens.

DVI to Video adapter doesn´t work! HELP!

I bought a dvi to video adapter (RCA or SVideo) and I already tried on two diferent TVs and none of them worked? What should I do? Does it have a setup to do?

We really need some more details to be able to help with your situation.
Is the adapter an Apple one, or some other brand?
What model TVs do you have? Please be as specific with the model numbers as possible.
When you say it doesn't work, what exactly happens?
And finally: what kind of Mac do you have? You posted in the Mac Mini forum, but your signature says MacBook.
If it is a Mac Mini, did you set it up initially using a regular monitor first?

Mac Mini with DVI to video adapter REFUSES to display on TV!! Please help!!

I purchased an apple DVI to Video adapter - which says for Mac mini and power mac G5 on the package. However not matter what I do, I can't get a picture on my TV, I have tried on 2 TV's and I get nothing but blank screen on both, with occassional grey flicking.
I thought maybe the adapter was faulty so had it changed, the new one shows the exact same behaviour. I have started up in safe mode, with the TV connected and still nothing, I have reset the PRAM and still nothing. Trashed the windowserver plists - and still nothing!!
I have searched through the forums as much as I can and can't find any answers.
Someone please help me out and tell me what I'm doing wrong.
Thanks very much.
Naj

Hi Thesserax,
Thanks for your reply, however I have already tried your suggestions - my tv's do not let me switch manually between PAL/NTSC, and I am definately on the correct channel.
I also tried connecting it to the TV and VNC'ing into it to try to change the resolution, however I although I see the correct CRT resolution opions i.e. 800x600 and 1024x768 only, I notice that I don't see any tv specific options such as overscan, and that the rates are stuck at 60Hz (NSTC) - I am in europe so the tv is PAL 50Hz and the adapter is also labelled PAL.
Any other ideas, please?
Thank you

Help! DVI to Video adapter not working!

Hello,
I bought a brand new DVI to video adapter and it's not working. I plug it in and it shows the start-up screen, but it's split screen and it's in black and white. Then, it goes into the black and white lines, not showing what's coming out of the computer at all. I've tried doing this on three separate TV's and none work. Can anyone help?

Can you give us your video card specs and the link to the product you are using.

Please help! Trying to buy a Apple Mini-DVI to Video Adapter (S-Video)

Help With Apple DVI to Video Adapter

I bought a Apple DVI to Video Adapter, which works fine when I connect my computer to my T.V. However, I want to be able to use both my monitor and my T.V. at the same time. If I connect the Apple DVI to Video Adapter to my T.V., then that takes away the port I use to connect my computer monitor. There is another port on the same card, but that size is not compatible with the plug on the of my monitor. Therefore I am limited to using either my T.V., or my computer monitor.
Is there any device I can get that allows me to connect the computer to the monitor and the T.V. at the same time?
Thanks

I thought that cables and adapters worked the same going either direction. I believed that the only concern was the male or female end points on them. Not sure anymore though

Colors using Apple TV versus a DVI to Video Adapter

Apple TV does not generate identical colors on my Panasonic flat screen (even when I adjust the screen's tint and/or colors) when I view iPhotos or videos (trailers, rented movies, homemade movies, etc.). However, Apple's DVI to Video Adapter (which only costs $19) does, and to perfection; the colors viewed on the Panasonic flat screen are identical to the images' colors on my MacBook Pro.
Does this make sense? Why wouldn't the more convenient Apple TV deliver the same results? Or is there something wrong with my $400 Apple TV?
Thanks for any advice.
Bob

You're still being a little 'cagey' and not giving us exactly the full information: "..The Apple TV is connected to the Panasonic flat screen via RBG component cables, run through a receiver.." ..the "receiver" is, presumably, a TV set or tuner. So is the Panasonic a TV set, or is it a dumb screen just connected - somehow - to a TV receiver?
You say "..For example, skin tones are way off, and a pink item in a photo can appear purple on the flat screen.." ..I'm not too good with colours, but it may be that your component connections are bad, and perhaps aren't making proper contact between your AppleTV and your "receiver" ..whatever that may be.
The component connections send specific colour ('chrominance') info, unlike the 'Video' (composite) output which sends the entire picture (all colours together) down a single cable, or the 'S-Video' signals which send colour (all together) and a separate brightness signal down different wires.
For a brief intro, see this 'Video Signal Standards' page ..or perhaps you already know all that.
It seems as if perhaps your component cables are connected to the wrong pins, have faulty connections, or your 'Component' input hasn't been properly selected on your Panasonic ..ahem: on your "receiver" ..or maybe your receiver's output is weirdly mismatched to your Panasonic screen.
Check your component connections at both ends: AppleTV and, er, "receiver". Pull them out one by one and see if there's a difference ..then put them back one by one ..or try putting them IN into different sockets. There's also a difference between analog and digital component connections: see the manual of your Panasonic and your, er, "receiver" to understand better what kind of incoming signal your equipment expects.
It could be just a loose wire, a wire in the wrong socket, or an incorrectly set up menu on your Panny - or your "receiver"!
Whoops - I've just re-read your last post: "..The Apple TV is connected to the Panasonic flat screen via RBG component cables, run through a receiver.."
The component cable are NOT "RBG" (..they're not even RGB, which is what I think you meant..) ..RGB (Red Green Blue) is not the component signal which the AppleTV provides: the ATV provides YUV component signals, generally referred to - or their connections on a TV (..or "receiver"..) designated by - 'YCbCr' or 'YPbPr' which would normally have sockets coloured whitish, bluey-green and red.
I think you've probably got your YPbPr wires crossed. The red, blue and green connections on the back of the AppleTV should NOT be attached to RGB connections on a TV (..or "receiver"..) but to the 'YCbCr' or 'YPbPr' sockets. If you have only 'RGB' sockets on the back of your (older?) equipment, that connection expects a different kind of signal, and the colours will be wrong. Maybe this article may help a little, or search with Google for more information..
Oh: and Winston says "..Have you tried toggling your HDMI setting on the tv, give all the settings (Auto/YCbCr/RGB) a whirl and see if this improves your experience.." Maybe you need to try switching the signal between YCbCr and RGB on the component output of your AppleTV (..if that's an option in its Settings menu; can't remember if it is or not..) to make sure that the output signal of your AppleTV matches the input which your other equipment is expecting!

Apple Mini DVI to Video Adapter - do you need cables as well?????????????

Apple Mini DVI to Video Adapter
i have this already,but do i need a certain cable to go into the TV. as it only has one port instead of the usual 3 av leads have???
help please,confused...............

Look in your question and you'll find the answer...
Apple mini DVI to Video Adapter
...the usual 3 av (audio/video) leads...
DVI is video only so you only need one port... if you were hooking up audio and video you'd need three (1 for video - 2 for the left/right audio channels)

Macbook + mini-DVI to video adapter problems!

Hi,
My roommate and I both have Macbooks - I got mine in June '06, it's one of the older black 80 gb models and hers is a white 120 gb that she got in August '07. We bought a mini-DVI to video adapter so we could watch DVDs and video files on our TV, but have been having some trouble with it lately. At first, it worked perfectly with her computer, but in the past few weeks has been malfunctioning - when she plugs it in, the default background shows up on the TV screen but nothing else, any windows she has open only show up on the TV if she drags them to the right on her screen until she can't see them on her computer anymore, so we're unable to watch anything fullscreen. Any tips on how to fix this?
Also, the adapter has never worked with my computer - any time I plug mine in, my computer display becomes enlarged and slightly distorted, and on the TV screen is distorted by horizontal lines that move up and down the screen. Any ideas here?
Thanks so much for the help!

Hi cbeth,
welcome to macbook forum.
For your friend macbook, try to press F7 back and forth to switch between mirror and expanded mode.
Try to update your macbook hardware firmware and software using software updater and repair permission after that...application/utilities/disk utility/repair permission.
Also reset your PRAM and PMU.
Open your friend system preference / display and try to compare and set yours similar to hers, including resolution, color depth, refresh rate.
Good Luck.

Apple Mini-DVI to Video Adapter Question

I want to hook up my macbook (late 2008 model) to my tv. Will the Apple Mini-DVI to Video Adapter
work? If it will work on my tv then what else do I need to get? It looks like you need other wires to hook up to your tv? Thanks in advance for your help!

The new MacBooks that use the NVIDIA 9400M video chip do _not_ support output to analog TVs. Thus, with the current MacBooks the only way to get output to an analog TV is with a third-party VGA-to-analog TV converter box -- you can't just use one of Apple's cables (although you'll need the mini display port to VGA adapter cable to connect to a third-party VGA-to-TV converter box).
More specifically, you can _not_ use one of Apple's $19, DVI to Video (composite/S-Video) adapters on the new MacBooks.

Apple Mini-DVI to Video Adapter Questions

I'm in the processing of producing an instructional video using an Intel Core Duo iMac and iMovie. This content will be distributed primarily via broadcast over cable TV. Considering this, I'd like to be able to edit and view my dv footage on a TV monitor as I work.
I was told by the Apple Store person that the Apple Mini-DVI to Video Adapter (http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/6314001/wo/jY18n ncCp3Nx2tYjws52iCaPkH1/1.0.21.1.0.8.25.7.11.2.3) will enable me to
1. Mirror my desktop to simultaneously show me what my iMovie edits will look like on a TV; and
2. Enable me to edit in iMovie using the TV as my desktop.
Am I understanding the capabilities of the Apple Mini-DVI to Video Adapter correctly?
Regarding Cables
1. I currently use an RCA composite cable to view dv footage from my camcorder directly on the TV. Is this the same cable I'd attach to the Mini-DVI to Video Adapter?
2. The DVD recorder/player my TV signal is routed through has an s-video port. Is there a benefit to using an s-video connection in addition to/or instead of the RCA connections?
Thanks for helping me understand this setup scenario!

Ditto to Karsten's post:
"Mirroring" a Mac's output to a TV, or plugging in an adaptor to provide a display on a Mac's screen and simultaneously on a TV ruins the Mac's display while this is happening by lowering its resolution. Ugghhh! (..I've tried this several times, in order to get a 'TV' signal out, showing the Mac's desktop, but it's hopeless..)
Karsten's method is the best - output to camcorder via the normal FireWire cable, and plug a TV or monitor into the camcorder's A/V Out socket!
[..Note, though, that Matti has pointed out that - what was it..? - during editing, some updating of the TV-thro-camcorder display doesn't work correctly. I can't remember exactly what the problem was, and I don't see it mentioned on Matti's Bugs Page, but there was some slight oddity. Nevertheless, this is still the best way of viewing on a TV or monitor..]

Annoying mini-DVI to video adapter...

I've been using a mini-DVI to video adapter, mostly to watch DVD's since my PS2 broke, for about a month. However, tonight when I tried to set it up, it didn't work.
I plugged in the cable and the adaptor and the only thing that would show up on the screen is my wallpaper-- not my cursor, or the dock, or the icons on the desktop. Just the desktop wallpaper. And nothing else is showing up.
Is the port fried? Or is it the adaptor? Which is more likely/how can I tell/how can I fix it? Thanks in advance!

The desktop background is visible, so it is working, but in extended desktop mode, if you move the mouse or drag a window far enough it will show up on that display.
options:
-close the lid, when the internal display shuts off the external will become the primary display, do you have an external keyboard/mouse to wake up the computer when the lid is closed?
-Use System Preferences: Displays: Arrangement to drag the white menu bar (and Dock) to the other monitor.
-Also, in System Preferences: Displays, check the Mirror displays to force both the laptop and the external display to show the same thing.
I'm not sure how your settings got changed or what you did before, but it's possible that something reverted to a default setting if you did some software update or something.
