Dvi to video, no display under bootcamp

Hello there,
and here is my situation:
i have a macbook pro running bootcamp, windows xp and an ati x1600. i recently purchased apples dvi to video adapter for the dvi port on my macbook pro but it will not send a signal (or at least a correct signal) to my tv.
a vga external display will work with the dvi to vga adapter under both OSes
and the tv will work under OS X with the dvi to video adapter, but i cannot, for the life of me get it to work under bootcamp.
i have tried all of the ati drivers i could find, old and new bootcamp drivers and the omega drivers. i have also tried forcing detection of my tv and all different resolutions to no avail.
any help would be appreciated.
cheers

im using the composite for now because i dont have an s-video cable.
if it helps you at all, i found a generic brand dvi to component cable after some searching in mom n pop computer stores. they seem to run abour $20 to $25.
but long story short, i need to use my tv-out on 2 different tvs and the second one doesnt have component or s-video, to i returned it without trying and got the apple adapter for dvi to video.
tv out in windows would be a huge help to me as well, lets hope someone can shed some light on this.

2 hi res displays with TB to DVI-D under Bootcamp?

Hello:
I do CAD work in the construction industry, currently using AutoCAD LT on a 2008 MBP running Windows 7 under Bootcamp. As part of this process, I frequently print drawings and check them (mark them up) against a variety of consultants' drawings before they are issued. I would like to eliminate the paper elements of this process. In order to do so, I would need to run a 30" screen to display the consultants' drawings at a usable size (the printed drawings are up to 36x48), likely a 30" Apple Cinema Display or a Dell U3011, both DVI-D, both 2560x1600, while at the same time running a interactive pen display, likely a Wacom Cintiq 21UX, DVI-I, 1600x1200, (my own drawings are rarely larger than 11x17) so that I can effectively use the mark up tools in Acrobat Pro.
Will the new TB-equipped MBPs run this scenario with Windows 7 booted? Will display resolution be maintained? What external adapters/hardware might be necessary? Any idea which MBP might have the minimum graphics card for this (I'm pretty sure I'll end up with one or the other 15" model, as I don't really have much use for a 17")? Anybody have any experience with a setup like this?
I know I could buy a cheap (PC) tower with a beefed up graphics card to do this, but my job also involves a certain amount of travel and I would like to have my CAD work accessible with a minimum of hassle while on the road (without having to carry external drives or worry about whether or not I have saved the right files to my laptop). I know I could also find a PC laptop that would do this (and I may have to), but the rest of my life is pretty focused on the Mac, and has been for decades, and I am pretty leery of PC laptops in general. Finally, I know that I could probably set up some sort of common file area (a FAT partition?) and simply reboot as a Mac when the time comes to check drawings, but this seems cumbersome at best.
Any help or advice is appreciated.
Thanks.
Best, Marcel

Hi Paco, as I understand it the Monitor has to be first in the TB chain, which would require a Monitor with another TB port out.

No display after sleep with macmini using DVI - S-video/composite under XP

Hi guys, I have installed XP on my mini. I have CRT TV so I'm using
DVI -> S-video/composite to output to my TV.
The problem is after sleep - there is no display (it's woking only after reset).
I installed the latest drivers from the mac os 10.5 DVD & updated the graphics driver from Intel.
Please help

Unfortunately, no answer, as I'm having the similar problem with a Samsung SyncMaster 215tw and a G4 Mini. It works with the DVI-VGA adapter and the VGA cable into the montor's VGA port. However, connecting with the G$ Mini's DVI port with the monitor's DVI port using a DVI cable doesn't work. I cannot figure out why this doesn't work.
The DVI cable is good and the monitor's DVI port is good, as the connection does work using my friend's Intel Mini's DVI port connected to the monitor's DVI port using the DVI cable.
The monitor is new, too, and otherwise works fine with my other Macs connected with the VGA port. (I've not tried the additional ports as yet.)
Although the monitor is supposed to synchroize automatically, I also tried manually presetting the G4 Mini to different resolutions, but that didn't make any difference. The screen remains black when it should be showing the booting Apple icon.
Any idea what is going wrong here, please, as it sounds as if this same thing occurs with various monitors?

Mini-dvi to video adapter changing display on macbook?

I recently purchased a mini-dvi to video adapter for my macbook to be able to view photos and video on my tv. I'm having trouble with the display on my computer when I use the adapter. As soon as I plug in the mini-dvi video adapter into the computer the display on my computer switches from 1280 X 800 to 640 X 480. Attached to the adapter I have an s-video cable to my tv. The display shows the same on the tv but in black and white.
Any ideas? Thanks!

Turn mirroring off. That way the two displays can run independently from one another. The mirroring check box is in Displays Preferences under the Arrangement tab.

The display brightness can't be adjusted in Windows 7 under Bootcamp 4, iMac 21.5 (mid 2011) with ATI Radion 6770M..

The display brightness of my iMac 21.5 (mid 2011, with ATI Radeon 6770M) can't be adjusted in Windows 7 installed under Bootcamp 4. I tried moving the brightness glider either with apple keyboard hotkeys (on-screen glider), or within Windows control panel brightness control (within the power option), but the brightness remains the same. I've had all software (Lion, bootcamp, windows 7) up to date. Please help. Thanks.

I posted a similar case to yours a month ago and it seems we're in a minority on the problem. What I have learned over this month was that Bootcamp drivers version 4 (Designed around OS Lion) was a BIG part of my issue with the ATI video. The new IMacs seems to require a customized by Apple Verion 3.2 or 3.3 to operate normally. Sadly, it's not as easy as just backing off version 4 and going onto 3.2 and getting the video slider back. You need to reload Windows and avoid Bootcamp 4.0 as it seems a piece of V4 gets stuck in Windows. I'm putting this suggestion to practise this week, guess I'll have more to say later.

Display problems using mini-dvi to video adapter

I recently purchased the mini-dvi to video adapter for my powerbook to use my TV as a monitor and to play pictures and videos from the laptop to the TV. I am getting a full color display on the TV, but it's only the screen saver. None of my files, text, or any other desktop folders or menus appear when I open them up on the laptop. The only screen that opens is the display preferences when I open that up, but it's a different set of preferences than what's in my computer's display preferences, as it's header is "NTSC/PAL". But other than that 1 menu, nothing is appearing but the screen saver.

OK, I discovered that I didn't know what I was doing. With the Mini-DVI to video adapter, you need to use an S-Video cable that plugs into an S-video jack on the TV, and then you need a separate cable to plug into the audio out jack on the MacBook to plug into the TV.
I think you could also use an S-video to RCA component cable if you have a TV with component video input, but I couldn't get that to work so I went to the s-video to s-video cable.

Connecting an Xbox using the DVI to Video adapter to a Display

I have a second display (Vision 17'' TFT LCD Display) and I love using it with my Power Book using the DVI out. I also have a PC that shares this display through a VGA input port also on the display. Anyways, I want to use the display for my Xbox which has the three component cables. To do this, I was planning on using the "Apple DVI to Video Adapter" but Is this possible? I know it works if the signal is going out the DVI port to an external display but does it work in reverse? In theory I would have the Yellow video cable going to the adapter and the two audio cables going to a "Y" stereo mini cable into the audio in port on the monitor. Possible? Other ideas? Thanks.
-Daniel

no, it won't work. the adapter does not transcode any video signal, it simply connects the appropriate breakout to the analog lines that are already present on the Mac's DVI output, as per the DVI-* spec. unfortunately, it will not work in reverse.
someone at Microsoft has claimed that the 360 does support HDMI and DVI, but the cable is simply not available yet. I find this comment somewhat suspicious, because the demand IS there already, and there is a HUGE base of people waiting for this.
MS does support VGA output now, so you could use a 2x1 VGA switcher to share the VGA input between the PC and 360. I would also get a KVM that supports audio. there are lots of options out there and they do not cost too much money. Y'ing the input on audio is not a great idea, because depending upon the impedence of the ins/outs, you might get a gain/distortion/bleed issue.

Messed up color display and resolution because of mini-DVI to video adapter

Once I connected the mini-DVI to video adapter to the tv and got weird colors on my screen for a while but then it worked out, then after a while I disconnected the cable and turned my computer off. After that, everytime I turned my macbook on, the color is fine for two seconds and then it turns into a weird offset color, really bright colors, kinda sketchy and just a few colors, and a weird resolution and display obviously, but then I just connect my Mini-DVI to video adapter and disconnect it again (quickly) and the color returns to normal. How can I make the normal colors stay and not have to connect the mini-DVI to video adapater everytime I want to see the normal color display and resolution??
please help!

Open the Universal Access pane of System Preferences, click on Seeing, turn off the White on Black, VoiceOver, and Zoom options, and drag the Contrast slider all the way to the left. If the issue persists, create a new folder on the desktop, drag half of the items from the Library/Preferences/ folder of the item in the Finder's sidebar with the house icon into it, and narrow down the files until you've isolated the one responsible.

Not detecting tv display when connected with Apple Mini-DVI to Video Adapte

I am connecting my macbook to my older tv using a Apple Mini-DVI to Video Adapter to an RCA (yellow video prong) and then into the tv. The red and white audio prongs hang loose, not hooked into anything on both ends. When I go into Displays there is no option for mirroring displays. I hit 'detect displays' but nothing happens. The Apple Mini-DVI to Video Adapter is brand new, just ordered it from apple. And I use the RCA cord all the time with other machines into my tv and it works fine.
Any help is really appreciated. Thanks!

Which generation MacBook do you have because at some point Apple dropped support for that adapter. Here is a link to a list of Apple adapters and compatible computer models:

Mini-DVI to Video to SD TV, no NTC display setting, fuzzy B&W picture

I've seen several posts on this topic but I haven't seen a specific one that addresses my problem. I apologize for rehashing an old topic but I'm fairly desperate at this point.
I have a Mini-DVI to Video adapter (from Best Buy and yes, I heard they had problems but haven't been able to find exactly what those problems are). I live in the United States. I am trying to connect my Macbook to my SD CRT TV and cannot get it to properly work. My first problem is that I do not have a display selection option for NTSC, 720x468 at 60Hz in my "Display" window. The second problem is that for all of the 60Hz display options that I do have the picture is in B&W and scrolls or displays multiple skinny images.
Please help!

The problem with the Dynex adapter, as near as I can tell, is that it doesn't have any EDID data inside of it. The Apple Mini DVI to Video Adapter does have a valid EDID inside of it. That's probably why your MB doesn't know it's connected to a TV, because it isn't being told it is by the plug-and-display driver (EDID), which is either missing or not correctly formed.

I tried restarting and using other displays.
Thanks,

Anyone else has an idea?
The subject has been discussed here: http://discussions.apple.com/thread.jspa?threadID=2136106&start=60&tstart=0 and apparently the problem is fixed with OS 10.6.3.
But I'm using 10.5.8! Thanks.

Can't display image on TV from MacBookPro (using DVI to video adaptor)

I purchased the apple "DVI to Video Adapter" to be able to use my TV as a display, but it isn't working despite help from the Apple help desk.
I'm using a standard TV video cable that plugs into the yellow video input jack, with is a Hitachi full multi-system C2578FS that works anywhere in the world. Before my iBook died last year, I used to watch movies from it on the same television using a similar setup (just VGA instead of DVI adaptor).
The television is not receiving the signal in any way. My MacBookPro is: the 'detect displays' when activated in my MacBook Pro's menu bar shows a display it calls "NTSC/PAL" which is the television, and I've tried each of the different settings to no avail.
Any ideas on how I might finally watch a movie or slideshow on my television?
Kind regards in advance,
-ck-

After much fiddling with display resolutions and TV setting, and several calls to Apple help, problem was found to have a really basic solution: replace the RCA connector cable. The old one was shot.

HT4617 Even though thunderbolt is not hot puggable in Bootcamp, is the use of mini displayport to vga/dvi still hot pluggable under Bootcamp?

Even though thunderbolt is not hot puggable in Bootcamp, is the use of mini displayport to vga/dvi still hot pluggable under Bootcamp?

This is Apple support on the subject

Can I plug and unplug devices into a Thunderbolt peripheral that is already recognized?
Yes. That is the best way to add and remove devices from the Thunderbolt chain while Windows 7 is running.
Have you tried?

Thunderbolt Display Connection to a DVI Port video card

Hi everyone, Im a snob to when it comes to computers and I'm kind of interested to find out if it's possible to connect my 27" thunderbolt display to my DVI port video card of my computer with this device: http://store.apple.com/us/product/H5236ZM/A?fnode=MTY1NDA5OQ&mco=MjI1Njk4Njg&s=t opSellers. Tthanks in advance for any info that I can get guys.

No. That will work only with Mini DisplayPort displays, not Thunderbolt. Also that particular model is single-link DVI, so is for the 24" display.

Hi there,
I am running Windows 7 x64 under bootcamp and want to be able to switch to target display mode.

I would like to do this so that I can easily switch to target display mode whilst using Windows without having to restart my machine.
Any help would be appreciated.
Cheers,

Windows does not have a Target Display mode.
