MBP + dvi-vga cable+ Canon LV-S3 Projector equals jittering picture

MBP + dvi-vga cable provided by apple connected to Canon LV-S3 Projector produced a jittery picture on the pull down projector screen.
Can I solve this shaky image by changing some screen resolution on the MBP?

no hdmi. it had 15-pin vga and usb, and the owner said there was a serial connection but I did not believe him.
connection thread was
mbp
dvi-vga cable
vga extender
vga port of canon
genius at apple store suggested going to display prefs and select "detect" displays to see if there is a problem and adjust mbp to the projector
but we could not test this

Problems displaying images on tv using dvi-vga cables

I connected my macbook to a Samsung hdtv via dvi-vga cables. The picture looked great on the tv, however it only displays my background. The tv does not display any open windows, desktop folders, or even the application dock at the bottom of the computer screen. Any ideas on what I may be doing wrong??

You need to go to System Preferences > Displays > Arrangement > Mirror displays

No Native Res with DVI/HDMI but OK with DVI/VGA cable on Loewe 32" LCD

Hi there, I am a little confused about connecting my mini to my Loewe Individual LCD TV and coudl do with some help.
I purchased a DVI to HDMI cable at enormous cost because my experience of DVI versus VGA is like night and day and I wanted to have the best possible connection to my HD TV.
The problem is that when I connect the mini with the DVI/HDMI cable the native resolution of my TV is not available. (1366x768 or thereabouts) The only resolutions to choose from are 1920 x 1080? and 1024 X 768. Using overscan on the 1024 fills the screen correctly but looks all stretched.
Instead I connected with a VGA cable and the correct resolution is automatically detected immediately and there is no problem at all.
I am a little bit confused as to why it works fine with VGA but not with DVI/HDMI. The VGA connection looks OK but why compromise when you shoudln't have to?

First of all, I am far from an expert but as I said, from my experience and after reading a LOT, HDMI cannot support 1366x768, that is why the TV goes without picture if you try. Why? I don't know.
Now, DVI is almost like VGA, both are analog, and can support 1366x768 or 1920x1200. But since you go from DVI output from the Mac Mini to the HDMI cable, screen goes black, blue, etc, res no supported.
That is why some people don't have problems with the powerbook and their HDTV's, and then they try with the DVI-HDMI adaptor (normally with the mac mini) and it's no good.
The thing is, you can get 720p, 1280x720 but with overscan, so with DisplayconfigX you go from:
1280x720 (720p)
128 Front Porch 10
80 Sync 5
200 Back Porch 15
1688 Total 750
to
1240x680
128 Front Porch 19
80 Sync 5
240 Back Porch 38
1688 Total 750
for example, with this setup you get the image cut to a minimum.
As you can see the totals are in both cases 1688 750. As soon as you don't respect this totals, like in this example:
1366x768
28 Front Porch 5
80 Sync 5
40 Back Porch 15
1514 Total 793
your TV won't be able to dispay the image. But with VGA the totals don't matter!!!!, that is why it works with one cable and not with the other.
Apple should update the Intel graphic card drivers, maybe that would help.

IPad 1 - VGA cable not outputting to projector, monitor or TV?

I recently purchased the apple VGA cable so that i could project powerpoint presentations using my iPad 1. I have no success at all using any applications to make this work. Slideshark, Keynote etc.
I had read that only video streaming is supported, however, i cannot get Youtube or any other content to show up. The cable works fine with my iPhone 4S.
Is there a setting I need to adjust on my iPad? When I plug it into a computer monitor, projector, or TV it seems to detect a signal but the screen stays black.
Any help would be very much appreciated.
Aleks

Thanks all... of course after I posted the query, I decided to do a forum search and found that this was not a unique question...in fact the VGA connector for the iPad1 is about useless. I did do a Slideshow and the images DID display on the external monitor. So the system does work, albeit with some decided limitations.
Well, not a reason to get an iPad2 yet, this was an experiment and not a regular requirement for me.
Still.... an odd decision by Apple to be so selective about what it allows to clone. And while they are at it, next time around, an extended desktop option would be really, really neat.

Macbook mini-dvi -- VGA projector problems

Hi
At the school i teach at we have problems hooking up our new macbooks to one of our projectors. We use a mini-dvi --> VGA cable to hook up the projector. The mac recognises the projector and it gets listed under screens, the resolution also changes. But no picture is beeing projected by the projector.
If we use a mini-dvi --> s/video/rca cable it works fine, but the quality of the picture is too low. The projector works nicely with the older macs we have, wich use the mini-dv --> vga cable.
Any toughts on what may be the problem, or what we could try?

I am having the same problem. I have to do powerpoint presentations at college and it was so embarrassing to go up there and my macbook not sync up. It use to work. I even bought a new adapter. It did not fix the problem. All the windows laptops were able to sync up to the projector but mine did not. This one one of the main reasons I bought a macbook. I need to take my work to school and connect to projectors. I am using the mini-DVI to VGA adapter. There appears to be no physical damage. When I click detect displays nothing happens. Now I have to redo everything on windows. Please, I hope someone has a fix for this. I am using the following; 2 GHZ Intel Core 2 DUo, 1 GB RAM, Mac OS X 10.4.10

"miniDVI-DVI adaptor" + "DVI to VGA cable" can't detect LCD TV

Hi,
I just bought a "miniDVI-to-DVI" adapter, and then a DVI-to-VGA male-to-male cable to connect my MacBook to Viewsonic 19" monitor but my MacBook didn't detect the 19" monitor. (This 19" monitor has only VGA but no DVI input!)I tried it on my friend's 32" LCD TV but it couldn't work too.
Then I tried to connect my MacBook by using "miniDVI-DVI" adaptor + "DVI-DVI male to male" cable to DVI socket of my frind's 32" LCD TV. It worked! So I think it's not the problem of the "miniDVI-DVI" adaptor.
I worried that it's the problem of the "DVI-to-VGA" cable so I went to the shop to exchange another new "DVI-to-VGA" cable. But my MacBook still couldn't detect all these 2 monitors via VGA socket.
Can anybody help me? Please advise! Thanks!

Hi,
Thanks for your response.
The shopman told me that "miniDVI-VGA" adaptor was out of stock, only "miniDVI-DVI" adaptor was available yesterday. At that time I thought I had to buy a connecting cable also (no matter it's VGA-VGA or DVI-VGA cable).
Since my friend has a DVI-DVI cable, if I buy this "miniDVI-to-DVI" adapter I may share my MacBook with his 32" TV too. So I bought these adaptor & cable.

How can i use the DVI-VGA adaptor under this particular circumstance?????

I got a LCD only has DVI-I port, while as u guys has noticed, the MBP only got DVI-I too. So, my first thought is to get another DVI-VGA adaptor. What i'm doing is to hook up the VGA port then plug each DVI port to LCD and MBP. Well, the problem comes out that MBP was able to indentify the Monitor but no image apears on Monitor. How can i solve this problem? Or do i need to buy any other accessaries to configure my MBP in order to make it work with the **** Monitor!

Right. You don't need a DVI-to-VGA adapter to connect DVI-to-DVI, obviously. The included DVI-to-VGA adapter is not meant to connect to the external display/projector, but merely to give you the proper connection to connect the VGA cable of the display/projector. I give a lot of presentations, everywhere I go there is a long VGA cable (at the podium, conference table, etc.); the short adapter is nice because I'd rather not carry a long cable with me...

Isn't the vga cable a little too short?

i want to buy another display or projector, but how am I supposed to connect my macbook pro to it when the cable is only like 4 inches long?

The cable is an adapter from a DVI input to a VGA... When you get your monitor/projector and it supports DVI then you will not use the adapter. You will only use the adapter if you need to connect the vga cable from the monitor/projector to the MBP. Hope that makes sense.

Santa Rosa MBP - DVI to VGA Projector problems

When hooking up a Sharp PG M20X using a [DVI toVGA cable] and a [VGA to DVI adaptor] the MBP sees the projector, but the projector cannot see the computer.
This is a problem because, I may find myself in situations where this is the only configuration for hooking my MBP up to a projector.
Note:
1. A G4 Powerbook works fine with this configuration.
2. The MacBook Pro drives the Sharp PG M20X projector DVI to DVI - without problems
3. The MacBook Pro drives a DVI to VGA CRT monitor - using a [VGA to DVI adaptor] - without problems.
Is there a solution?
Thanks
I have a 2.4 GHz Santa Rosa C2D MacBook Pro Mac OS X (10.4.10) Sharp PG M20X Projector (DVI-input)

I think I solved this problem.
It was in issue for me. My second monitor would only display the Windows XP screen when it was loading, then it would black out. I couldn't even move my mouse arrow to the other side. Then I fixed it, here's how (running Windows XP SP3):
1. Start > Control Panel > Appearance and Themes
2. Display
3. Go to tab "settings"
4. Double click the blue image with the "2" inside it. This is the second monitor, adjacent to your first, or primary, monitor. The blue box may be a desaturated, greyish blue, meaning that the monitor is disabled. Click it and it a box will pop up asking if you want to enable the monitor. Click OK, and then like magic, your monitor is resurected in it's Windows Glory! From there, adjust the resolution, and it should work perfectly.
This isn't a Boot Camp compatability issue, it's just a problem with the lack of familiarity that users of OS X have with using XP.
Have a nice day!

Mini DVI to VGA cable doesn't send signal to the projector

I just received a mini DVI to VGA adapter cable today.
I connect mini DVI side of cable into my Macbook v. 4.1 and connect the other side into DGA cable, which connected to LCD projector.
When I connect the cable to my Macbook, the opened application streched out to a full screen (seems like computer detets the cable) but projector says 'no signal'.
Can any one tell me what is wrong it is?
Thanks much
Mike

I'm still stucked.
By reading some articles, it says even using mini DVI adapter, the signal is still digital and if the projector doesn't accept digital signal then it's no use....
My projector is Epson EX3200 and it doesn't have any DVI or HDMI input.
Does this mean my projector doesn't accept a digital signal?
But, but, but if even uing mini DVI adapter cable it still doesn't conver to analog signal then why they call the cable a mini DVI to VGA cable???
Why should this world be so complecated.....

I am trying to hook my macbook pro to a projector, which has a VGA cable. I bought a VGA to HDMI adapter, but whenever I hook it up, the screen on my macbook just goes black and I can't make it do anything else or even show up on the projector.

My laptop is still on; it just has a black screen that I can't get rid of without shutting down the computer by holding the power button.

Hey there lynmrigg,
It sounds like have an HDMI to VGA adapter connecting your MacBook Pro and your projector but the screen on your computer goes black and no image appears on the projector. I would use the troubleshooting in the following article to help resolve or isolate the issue here, named:
Apple computers: Troubleshooting issues with video on internal or external displays
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
Take care,
Sterling

Mac Mini with BenQ W100 Projector (No signal with DVI Dual cable)

Hi all, just bought a Mac Mini Intel 1.6ghz. Also have a BenQ W100 Projector which have been using for some months with a PC. Now comes the problem! I have bought a DVI-DVI cable (Dual link) and plugged the Mac into the Projector and NOTHING APPEARS! No source found at all. The input on the projector is DVI-I according to the BenQ website.
Question is, am i using the right cable? Is the Mac Mini even compatible with this projector? Nobody seems to know, even BenQ!!
Thanks for any help
BEN

Hi, FYI this is the cable I have. Strangely it only references HD sources and not computers on the description? I would note that PC World (where i bought it from) have shown this cable operating on a PC unit and LCD monitor so im presuming its nothing to do with the cable?)
http://www.amazon.co.uk/Belkin-PureAV-Digital-Video-Dual-Link/dp/B0003057GO[/URL]
I used a VGA to DVI cable when the PC was running on the projector. which shows a picture no problem. I tried using the DVI/VGA adaptor that came with the Mac then plugging the VGA-DVI cable into it. As i say no picture just a flicker now and then.
I have tested Mini and he works fine on a LCD TV using the VGA/DVI adaptor and a standard VGA-VGA cable.
I guess i will exchange the cable and see what happens!

I bought a mini DVI to HDMI convertor and a HDMI to VGA cable to connect my mac book pro to a tv but it doesn't work any one can help.\\\\\

i bought a mini DVI to HDMI convertor and a HDMI to VGA cable to connect my mac book pro to a tv but it doesn't work any one can help.

I would suggest looking into a Thunderbolt to HDMI connector. In this case, you may be able to use the TV as an external monitor. For this option, please confirm through additional research. I have not tested it personally.
You can also use an Apple TV, which connects with HDMI. In this case, you can use Airplay Mirroring. Not all Macs support Airplay Mirroring, so you need to check first. I have a Mid-2011 27" iMac, and it supports Airplay Mirroring. I don't use it often because my TV is in another room, but I just tried it and it worked. It had to change the screen resolution to work well, so I don't know if I would want to use it as my day to day monitor. http://support.apple.com/kb/ht5404

Mini DVI to VGA cable won't fit. Too big for slot on 12 PowerBook G4

Are there more than one type of cable?

http://support.apple.com/kb/HT2369 shows only one kind of mini-DVI port for the 12" Powerbook. Sounds like you got something that is not an mini-DVI port based cable. Mini-VGA cables look very similar, and can be misidentified. What are you connecting to from the Powerbook G4? Make, model # is important. Often DVI-HDMI adapters are better than DVI to VGA if there is an option. Cause DVI-VGA you need a proper digital/analog converter in the cable in question.
