IBook VGA to TV Input

Hi All,
I've just purchased a VGA to s-video/rca adapter (Strait Wire, no electronics) and I Plugged it into my iBook G3 600MHz 10.4.2 with the Apple supplied mini video to vga adapter. Well, it recognized a connection and brought up the appropriate display preference panel. However, none of the resolutions or frequencies worked and displayed a correct picture on the TV. BTW, this only worked with the rca (yellow) connector, not the s-video connector. I have hooked up vga to s-video and rca connectors before, but always with some sort of electronic box between them. I suppose I was hoping to get a cheap alternative using just wire.
Was I completely wrong? Do I have any chance of using this wire? Is there a suggested vga to s-video/rca convertor that works well? One that works best? Thanks for any help!

Which cable are you using? http://docs.info.apple.com/article.html?artnum=88396
Do you have the correct one foryour book?
I needed to connect my old 500Mhz iBook to the RCA ports at teh back of my TV as the front ports did not allow the book to "see" the TV.

No VGA or DVI input signal

I recently found my old HP Pavilion a6228x after 2 months of not using it, and hooked it up to my w1907 monitor with a vga cable. It says that there is no VGA or DVI input signal, with the black arrow pointing at DVI. I can't switch from DVI to VGA because everytime I press the menu button, the screen will say "Monitor going to sleep." The monitor works fine with my laptop and the same vga cable. Help?

Hi,
Since the monitor and cable are known to be good then make sure that you are plugging the video card into the video card's VGA port if a a video card is installed. If the video card has a DVI port then use a native DVI cable between the monitor and the video card.
If there is a video card in your PC then try reseating it (remove and replace). If that doesn't work then remove the video card and plug the VGA cable into the motherboard's VGA port.
Only connect one active video feed to the monitor.
Try a monitor reset. Unplug the monitor’s power cord and hold down the monitor’s power button for 30-60 seconds. Plug the monitor back in and power it up.

Mac Mini to Samsung LE37R87BDX 37" VGA to Pc Input - No Display

I have a mac mini 1.66 Intel running 10.4.11, into which I've got the VGA adapter plugged, this is cabled with a VGA cable into my nice new Samsung LE37R8 flat panel LCD on the pc port.
The image flicks up briefly, but then it goes black and it won't display.
Connect the same machine up running windows XP under boot camp and bingo, it works beautifully.
Oh and I've tried a windows pc running xp as well and that displays also, so I'm pretty much convinced there's nothing wrong with the tv or the cable.
I think it must be the Os settings..
The odd thing is that I can remote desktop to the mac mini and it detects the display correctly, as far as I can see, even listing 'Samsung' as the colour profile and the changing the resolution to a supportable (well, as far as I can see from the tv's manual) to 1366x768 at 75hz.
I've tried changing the resolution, 1024x768, 800x600 etc etc, changed the frequency to 60, but to no avail.
Anyone got any ideas?

I am having an identical issue with an intel dual core mac mini and a 50" plasma Samsung TV (PS50Q97HD). I've sucesfully connected my mac to a 17" LCD monitor with the DVI-VGA adapter and I've connected a windows XP laptop to the Samsung TV using a VGA cable.... but I have had no success with the mac to Samsung connection.

IBook VGA output to projector = "No Signal"

This is a recent intermittent fault.
iBook G4 14" >> Apple VGA Adapter >> Sony Projector (several models tried)
I'm getting a "No Signal" message on the projector.
Once I was able to open the Sys Prefs display panel and use 'Detect Displays' which got it working again but since then the iBook seems to refuse to output a signal. Internal LCD works fine.

Do you have a second vga adapter to check it against? Your project may require a certain video mode for its use. If you have your external vga set to the wrong resolution it may not be able to lock onto the signal.

IBook VGA DVI

I just bought an iBook g4 12" 1.33 GHz. It has not arrived yet but I was wondering what solutions if any do users use to connect it to en external DVI dislay. I have the DELL 24" flat panel. Is it possible to use the video port adapter to vga and then avga to dvi adapter? Or can I just use the video port to dvi adapter that is used for the powerbook?
-=Sunnah=-

Hi Sunnah,
The PowerBook adapter is a mini DVI to DVI and won't work with the iBook. I think you need a VGA to DVI adapter. It should work fine with the adapter that comes with the iBook. The Apple DVI to VGA Display Adapter may work. I don't know why it wouldn't but it says in the discription that it's for DVI to VGA not the other way. I don't think it's one way only but you may want to check with the Apple Store before buying it.

Is VGA a common input to a video projector?

What are common inputs on video projectors? If I get a VGA adaptor for my iPad 2, can I feel confident that it will work with a projector at a meeting I will attend?

Yes, VGA is a common input.

How can I mirror my macbook pro desktop through Airport Extreme to a digital projector with only VGA and DVI inputs?

How can I mirror my Macbook Pro desktop through Airport Extreme to a digital projector with only a DVI & VGA inputs?? Want to use it for presantation like Keynote/ Pages.

Never mind, I solved it. Didn't know the converter needed a power source to operate (duh!) Now I have that, it works just fine.......

VGA/DVI Input

The monitor I use for my PC just went up in smoke, and I'm wondering:
Is there any way I can allow my iMac's display to accept VGA or DVI input? I don't use my PC that often, and the amount I'm willing to invest in a new monitor would only fetch me something mediocre. BAH! I already love my iMac Display and it requires so little desk space...
I'm thinking of something like a USB or FireWire device that acts sort of like a KVM switch, allowing me to switch between my Mac/PC instantly. Could something this simple and useful possibly exist?

Microsoft has this:
http://www.microsoft.com/mac/otherproducts/otherproducts.aspx?pid=remotedesktopc lient
It works great. A few catches, but nothing major:
1.) have to set the IBM to a static IP on your network and use that as the login
2.) works for free on windows XP Pro. Not sure if they sell the option on the others or not.
3.) This is kinda funny, you have to have a password on your user and login, then the network shows up and the computer works.
Basically you need to borrow an older IBM CRT (most people give them away) to set it up and then you can use the mac. I just set a standard password I can easily type in.
In fact, it is like 100000% better than virtual PC for mac, because it actually runs the IBM and just transmits the info through the network (most are atleast 100Mbs)
Hope that helps,
Brian

How to connect apple tv to vga output

I have a non-HDMI TV and want to connect via my vga and audio inputs. I know there is a device out there, but can't locate. Help appreciated.

HDMI is the only supported method, there will be no guarantee. You would also run into issues with HDCP content (ie iTunes, Netflix)

Mini DP to VGA or Mini DP to DVI?

I need to connect my MacBook (late 2008) to my AOC Fovi F22 display. The display has VGA and DVI inputs. The display resolution is 1920x1080 Full HD.
1. Which one is the more sensible choice? DVI perhaps?
2. I hear that people are facing issues with Apple adapters nowadays. There are threads here too, talking about those issues. Should I go for 3rd party adapters instead?
3. I have a spare DVI to VGA adapter. If I get the DVI adapter from Apple, will I be able to get VGA output using my DVI - VGA thing? Is the Apple adapter Mini DP to DVI-I. Or is it just DVI-D?
Thanks.

DVI will have better image quality overall. sharper text & video. the color too will be more accurate.
2. I hear that people are facing issues with Apple adapters nowadays. There are threads here too, talking about those issues. Should I go for 3rd party adapters instead?
is somewhat true. others have had bad trouble, the only issues I've had is a snowy screen for a second when I switch imputs on my display between DVI & VGA as I have 2 systems plugged into it.
try monoprice.com for the adapters.
3. I have a spare DVI to VGA adapter. If I get the DVI adapter from Apple, will I be able to get VGA output using my DVI - VGA thing? Is the Apple adapter Mini DP to DVI-I. Or is it just DVI-D?
No, the std MDP > DVI doesn't support the analog passthru for VGA.

MBP CD2 DVI to VGA not working with projector

I am having issues getting the MBP to recognize a DELL 2300 projector through a DVI to VGA apple cable.
A few months ago there were posts about this, but no solutions. The problem seems to be with the 'INTEL' side of things, as the same projector with the same DVI to VGA apple cable works on an older G4 tower running 10.4.9. The projector also works on an old G4 iBook with it's version of a VGA adapter. To make things more confusing, a DVI to Video apple cable works with the DELL 2300 on my new MBP C2D-but produces a terrible quality picture. Mysteriously, my previous 1st generation MBP CD worked with the DELL 2300 via a DVI to VGA apple cable (but I'm not sure which OS was out at the time 10.4.8?)
My new MBP CD2 definately recognizes the projector through the DVI to VGA adapter, but the projector doesn't recognize the video signal from the computer. It is DEFINATELY the MBP (or universal drivers), as I have checked the DVI to VGA dongle (works), have checked the projector (works with an ibook running 10.4.8 OSX with VGA dongle), have changed resolution settings before and after connecting, have restarted computer, have tested various orders of connecting the projector and cables. STINK! (I also have TWO DVI to VGA adapters, so it is not a bad adapter). I have also played with exchanging various plist files from older universal versions of 10.4.8 that worked with the projector-no help.
As I stated, the projector will work (in horrible quality) with a DVI to Video dongle. Why it will not work with the DVI to VGA dongle is a mystery and annoying I would hope that a newer MBP CD2 would be plug and play (like my previous MBP CD and an old G4 tower and an old iBook G4...but no).
Any ideas, any help, any answers?

Here are the actors in our play today
1. MacBookPro A. (my system a CD2 2.16 with OSX 10.4.9)
2. MacBookPro B. (my friends system a CD2 2.16 with OSX 10.4.9)
3. an iBook (my friends 1.07 GHz G4 with 10.4.8 and a VGA adapter)
4. DELL 2300 MP projector
Plugged in DVI to VGA adapter to the virgin MacBookPro B (never had the projector plugged into it before) Dell projector shows that it recognizes an analog RGB 800X600 signal from MBP B. It projects a beautiful desktop. All is well for a moment.
In Display preferences we see for the MBP B
Color LCD, Display: 800X600 stretched, Colors: Millions, Refresh Rate: N/A
VGA Display
Now, I unplug the DVI to VGA adapter and naturally MBP B readjusts to it's native resolution. Great.
Now I immediately plug back in the DVI to VGA adapter. The computer and the projector searches for signal with none found, while the computer shows no attempt at an automatic readjustment as above (800X600 stretched).
I try the 'detect display' option. It causes computer to stall for a second (as it searches) but it does not detect projector and does not readjust it's own resolution to 800X600 stretched as it did initially. F7 key does nothing.
This is a problem!
So, I shut down the projector. I unplug the projector's power source and waited 20 seconds. plugged it back in, started projector back up.
I shut down/restarted the MBP B.
I plug back in the DVI to VGA adapter into the MBP B. The MBP B screen flashes to all blue, but does not automatically change to 800X600 stretched (remains at native resolution and does not recognize an external monitor/projector)
Enter the iBook!
I plug the iBook's VGA adapter into the projector. The projector shows that it recognizes an analog RGB 1024X768 60Hz signal and projects desktop screen immediately. Plug and play!
iBook display prefs reveal:
Color LCD, 1024X768, colors: Millions, Refresh rate: N/A
Color tab: Generic RGB Profile
VGA display, 1024X768, colors: Millions,
Now. I unplug adapter from iBook, iBook readjusts to native display
plugged back in adapter to iBook, immediately recognizes and displays projected desktop.
Scene 2: The FREAKY thing!
Now, I immediately (after unplugging the adapter from the iBook) change adapters to the DVI to VGA adapter and plug the projector into the MacBookPro B, whallla! Back in business. (computer screen adjusted to 800X600, and projector recognized signal).
Now, what about my computer? I unplug from MBP B and plug into MacBookPro A, and NOTHING...the computer doesn't automatically adjust to a new resolution, and the projector doesn't recognize any signal from the computer.
Ahhhh Freak out! Now, I plugged adapter back into MacBookPro B, and now back to NOTHING. MBP B no longer recognizes projector or readjusts it's resolution. Was something somehow corrupted?
Now, I plugged iBook VGA adapter back in, and iBook once again with it's awesome G4 technology (or dated video drivers or something) recognizes the projector in an instant and projects the screen.
Now, logically I try again to immediately unplug the adapter from the iBook and switch adapters and plug back into MacBookPro B-it worked once right? But, sorry, NOT twice. The mystery deepens.
Well, I think, maybe it is because I didn't restart MacBookPro B before attempting the switcharoo from iBook to MacBookPro.
So, I plug back into iBook-projector. And the iBook works immediately again.
I restart MacBookPro B and plug in to the freshly restarted MBP B...HOUSTON WE HAVE LIFT OFF! The MacBookPro B recognizes the projector and the projector kindly displays the desktop.
Now what about MacBookPro A...Last time, when I did the switcharoo, it corrupted something to cause the MBP B not to work. Let's try it again. Will this plug-unplug-restart-switch adapters-immediatly plug in technique work...let's see. I restart MBP A, and plug DVI to VGA adapter in. Sorry. Same ol' no signals recognized. MacBookPro A not auto readjusting resolution, and does not list any projector in display prefs.
Let's get crazy and immediately plug the adapter into the MacBookPro B...it works-oh so logical...NOT! Why wasn't it corrupted this time by MBP A? MacBookPro B readjusts its screen to 800X600 stretched and projector immediately recognizes and projects desktop.
Now lets see if I can break it again as before. I unplug it from MacBookPro B and back into MacBook Pro B, knowing that this caused it to stop working previously. And...it still works-WHAT? I do it a third time. It still works on MacBookPro B.
So,
I plug it back into MacBookPro A...still nothing. Back to MacbookPro B works like a charm. This time it struggles a bit showing that initially it sees a signal from MacBookPro B of 1192X900 (i Think), then the MacBookPro B switches automatically to 800X600 and the projector works.
Wait..I see something amiss! I see in my MBP A menu bar an icon for Labtick which MBP B does not have. I shut down Labtick, plug back in the DVI to VGA adapter and 'Boom' the projector is recognized.
I unplug DVI to VGA adapter and plug back in to MBP A and 'Boom' the projector is recognized again...no it couldn't be!
Well, it is possible it couldn't be because, I shut down the projector, unplug it's power source, plug it back in. I plug it back into the recently working MBP A with Labtick not running, and sorry folks, now the projector doesn't work again. The MBP A does not readjust it's resolution, nor recognize a projector and the projector doesn't recognize the MBP A.
Let's try the projector in MBP B....same deal. Now it doesn't work. Same symptoms of MBP A.
Back to the good ol' iBook. Of course it works.
Now switching over directly to a restarted MBP B. -DOESN'T WORK (as it did using this technique previously)
Now switching over to MBP A- DOESN'T WORK.
As you can see, it is hard even with multiple computers to find a series of doing things that consistently makes the projector work.
Any thoughts, ideas, ways to diagnose? Thanks!

Mini DP to VGA or Mini DP to HDMI?

I have three questions about connecting a HDTV that supports 1080p to my iMac in order to use it as a second monitor. The TV has both VGA and HDMI inputs. I have found (online) adapters to connect both the VGA and the HDMI on the TV to the Mini DisplayPort/Thunderbolt port on my iMac as well as cables that will achive this without the need for adapters. The cable(s) seems easier yet most claim they don't support audio and that leads to question one. Though the cable(s) seem easier I'd like to have audio on the second display and that leads to question two. Audio aside and this is simply to expand my iMac's display leads to question three.
1) Do Mini DP to VGA and/or Mini DP to HDMI cables and/or adapters support audio?
2) If the cable and/or adapters don't support audio is there a way to achieve this result?
3) Which will have better results as far as image quality (hoping for audio as well) VGA or HDMI?
Thank you for any help.

VGA does not support audio.
The > Moshi Mini DP to HDMI Adapter with Audio Support - Apple Store (U.S.) is what your looking for.

VGA to SCART Cable

Hi. My TV doesn't have VGA or DVI input. It only has SCART. Can somebody please tell me if MacMini will work with VGA to SCART cable?
Thanks

Hi,
Based on the specs of the LG unit:
(a) SCART to VGA: Most likely the signal frequency on VGA port of a normal computer monitor does not match the signal frequency of the SCART port therefore you can't get the pictures/images.
(b) SCART to DVI: you need more than just a cable, you need a converter because SCART uses analog signals and DVI use digital signals.

VGA vs DVI with regards to projectors

I have recently purchased a BENQ MP620 DLP projector to use as a home cinema and for my artwork. It is running off the VGA port of my Mac and produces a very good picture as is. However, is it worth running it off the DVI port; will there be a noticeable improvement in picture quality? I also use a LaCie 22" monitor on the VGA port and having to swap the cables is a pain. I know I could buy a VGA splitter but a bit more money could buy a DVI cable instead. Having blown my money on the projector I am a little strapped for cash at the moment! I definitely can't afford a new graphics card...
Many thanks
William

The school I taught at used projectors with both VGA and DVI inputs and to my eye the DVI output seemed sharper.

[MOVED] H55 chipset and KMS with HDMI/VGA

I recently purchased a Shuttle SH55J2. As there seems to be KMS issues with the Auburndale chipset and the VGA output (output is wavey with KMS on, no X with KMS off), I am attempting to get the HDMI output working with my monitor. I am using a Dell E248WFP which has VGA and DVI input. I am using an HDMI cable with an HDMI-DVI converter.
The problem is the monitor comes up with screen with green background and white text starting from bios all the way through boot to login. I have attempted changing the colorspace of the monitor from RGB to YPbPr, but it simply changes the color of the background. Any clues on how to fix this?
New: I've bought a new hdmi capable monitor. However, with KMS enabled using HDMI->HDMI, the monitor receives no signal, while the HDMI->DVI still has the color problems. With KMS off, HDMI->HDMI works and HDMI->DVI has no signal. So now it appears the KMS is the real issue.
Note: This discussion has been moved to the intel-gfx mailing list: http://lists.freedesktop.org/archives/i … 08315.html

It's likely that the laptop's attempting to output audio through the HDMI as well. Have you tried this? Right-click on the speaker icon in the notification area near the clock (in Desktop mode) and select "Playback devices." What's listed there, and what has the green check mark? Try selecting your speakers and clicking "Set Default."
