PowerMac G5 VGA connection to LCD

I have a 30" LCD widescreen TV which has a VGA input. When I connect my PowerMac G5 to the VGA input on the LCD, I get a "incompatible format." Any ideas what I need to do to be able to connect my computer to this TV? WHat am I doing wrong?
The TV is a Westinghouse, if that matters.
thanks....Nancy

Hi - Update for anyone that is interested. I've had a play around...
I went into System Preferences/Display and connected the TV.
The resolution still changed but I went to 'Arrangement' and deselected 'Mirror Displays' (10.5.7 to thank for that) My screen on the MacBook returned to its normal resolution but the TV was still not working.
I selected 'Display' and then 'Gather Windows' and on the TV's Display changed the resolution to 1600x1024 instead of the one 10.5.7 assigned.
Bingo! It's all back up and running!
Wish I didn't have to spend 20 mins on the phone to Apple though with no solution - that'll be added to my student phone bill! ARGH!

10.5.7 - VGA connection to LCD TV on new MacBook Pro dead. HELP PLEASE!

I don't have a clue what's gone on here.
Just downloaded the latest update and the connection to my TV has gone mental. It changes the resolution on my MacBook screen to something ridiculous and doesn't properly connect to the TV screen.
Obviously, this is because of the new update is there anyway of going back to 10.5.6? I want to watch Curb Your Enthusiasm on my big screen!
PS I've only recently moved to Mac so could any advice be idiot proof.
Thanks

PowerMac G4 (AGP) and HD LCD Monitor

I gave my daughter a few years ago my old G4 PowerMac (AGP Graphics) which has a VGA port and is connected to a huge Apple 17" CRT Studio Display. I'd like to give her a modern LCD display. The HP 2009M HD LCD Monitor states that it comes with a standard analog VGA input. Is there any reason this monitor would not work with the G4 PowerMac?

I looked at the HP site and it didn't mention anything about being able to use this display w/ Mac computers. It Looks like this LCD panel is Windows XP/Vista only.
Not sure why it wouldn't be Mac-compatible, though.
You could just do a search for Mac-compatible LCD panels or monitors and see what comes up.
There are plenty of non-Apple LCD panels that work fine with Macs.
I had my girlfriend purchase an LCD flat panel monitor that was, relatively, cheap. It was labeled only worked with Windows. We bought it and it's connected up to a Radeon 7000 video card via DVI in a old beige G3 box upgraded to G4 status and it works fine.
With using the VGA connections, I can't see why the HP wouldn't work.
Personally, I have found that most LCD displays are not platform-specific, anyway.
The HP should work fine.

23" Cinema Display and VGA connection ??

Hey all,
I have a VAIO S580 notebook and a 23" Apple Cinema Display. The VAIO uses a VGA connection to connect to external monitors. I have been looking for VGA to DVI adapters that would allow me connect my VAIO to my ACD. However, I could only find adapters that are DVI-I and DVI-A thus far. Will these adapters work for my setup?
TIA

Monoprice.com is another good site. I have a question for everyone. I have a Powermac G4 and 21" cinema display. I recently connected the computer to a tv via a DVI to HDMI cable. It worked fine for a few days. Now when I restart the screen freezes without a toolbar at the top of the screen or the dock. If I unplug the cable the screen goes blank for a second and both the toolbar and dock appear. Can someone help with this?

DVI or VGA Connection For Sharp Aquos??

I've got an older Sharp Aquos, specifically the LC37G4U. Previously owned a Mini G4, 1.42 GHZ. The best I could do imagewise was with a DVI connection and the Aquos and Mini set to 1280 x 768. This resulted in an image cropping of approximately 1/2 inch on the right and left sides of the screen. I lived with it for a few years. I recently upgraded with a sweet Mini Duo Core 1.83 GHZ, 2 Gig of RAM, 7,500 RPM Seagate HD, etc. The computer is great, but with the DVI connection, it appears to default to the old 1280 x 768 setting, with the same exact image cropping. The maximum resolution on the LCD is 1366 X 768, and I'd like to attempt to do better as far as the cropping goes. Has anyone out there tried the VGA connection alternative? Or if anyone has any ideas, I would be forever in your debt. Thanks All!
Mac MIni Duo Core 1.83Ghz, 2 gig, etc. Mac OS X (10.4.9)

I have a sharp lcd tv as well, and as far as I know, if you connect the mini to it using DVI (you shouldn't really use anything else) the mini will default to the tv's resolution. I swap my mini from monitor to tele depending on what I'm using it for, and everytime it automatically fixes it's display settings to match whatever is connected to it. Hopefully this is the case for you too, try it out.

Connecting to LCD Projector

Before owning my current MacBook pro Core2Duo I had MacBook Pro CoreDuo and PowerBook G4. With these previous laptops I was able to connect to LCD projector no problem. Now I am in Japan in big business meeting trying to connect my newest MacBook pro to the same projector as was working with my older Mac and nothing. I tried mirroring on and off, change projector resolution, change display preferences. Nothing. I had to copy my PowerPoint to someone who had Dell PC and work off it.
Any idea how to fix MacBook Pro that it would work with LCD displays.

Hi,
I had some trouble initially, too, but now I use the "detect displays" option and it usually works fine. Here are a few more tips copied below--these are not my own--but I forgot to make a note of who to credit.
Good luck,
Bill Durbin
Projector Troubleshooting
For some reason, Apple thinks it's important that you connect the VGA cable to the adapter first, and then the adapter to the computer, in this order. Have you done this?
Try forcing the MacBook Pro to re-detect displays by pressing F7 (or Fn+F7 if you have customized the function keys).
Go to System Preferences>Displays> and click on “detect displays.” Also go to Arrangement and then check the box that says "mirror displays."
Also try setting the resolution output to whatever the projector is (1024x768?).
"To detect the TV or other external device, hold down the Command (x) key and press the F2 key. You can also open the Displays pane of System Preferences and click the
Detect Displays button.
6 To adjust how the image is displayed on the device, use the Displays pane of System Preferences."

How can i get a VGA connection? I cant find the right cables?

i wish to get a VGA connection for a Projector or stuff like that? I looked on the apple site for a cable but cant find one that has the right port for my computer... any ideas? i have a new Macbook Pro.

Hi tjk,
I am taking advantage of clump´s post, but I have an issue with the following. I looked in my local retailer recently for a DVI to HDMI adapter... but they are out of stock. I need to plug my MacBook Pro to my TV, and then I have a DVi to VGA adapter, and my TV (Sharp Aquous LCD) has an analog PC connection. I tried to see my desktop in the TV, but the TV is not recognizing the Mac... do you if it is feasible to have the TV recognize the Mac through a DVI to VGA adapter?

Connecting 2 LCD monitors to my Macbook?

Hello Everyone.
Ok, before I go poking around and stuff something up, can someone please answer my following questions. I am wanting to connect two LCD 22inch monitors to my Macbook Pro.
1. How do I do this?
2. Instead of buying Apple screens, are there any other good LCD monitors that will do just a good a job?
Please help.
Thanks....I love my MAC

1. http://www.matrox.com/graphics/en/corpo/products/home.php
check graphic expansion modules
2. for serious work I would strongly recommend eizo monitors. current apple displays simply cant compete with them. They are very outdated and therefore overpriced. they have poor adjusting possibilities..in both picture and stands.

What's a DVI-to-VGA connection have to do with sleep?

I've been experimenting with hooking my HDTV to my Mac Pro's 5870 video card. Currently I have my 27" ACD connected to one of the mini displayports (mDP) and a VGA, connected through an Apple VGA-to-mDP (active) adapter to the other mDP. When I want to use the TV I can connect the HDTV to the 5870's DVI connection with a (passive) HDMI-to-DVI adapter. It works. Indeed it works too well! Whether the TV is taking input from the computer or not the computer thinks the TV is a third monitor which can get very confusing when the mouse is accidentally moved off my ACD on to the TV (6 feet away) and I can't find the cursor. Another minor nit is that using the DVI means no audio can be passed on the HDMI so the computer speakers are used unless of course I hook up a separate audio connection.
I could get around the 3-monitor problem using SwitchResX but I prefer not to. I'm willing to simply manually connect and disconnect the HDMI cable on those few times I want stream stuff to the TV. But as an alternative I tried switching the TV and VGA connections, i.e., connect the TV to the mDP through a (passive) mDP-to-HDMI adapter and the VGA through a (passive) VGA-to-DVI adapter.
This second scheme also works. However because all the adapters are now passive the VGA will disconnect when the HDMI is plugged in. Ok. I can live with that and I understand the behavior due to the 3-monitor limitations of the 5xxx cards (i.e., active adapters required).
All the above was just background and context leading to the question I entitled this post with. Forget the HDMI connection. I have the ACD connected to its mDP and the VGA through the passive VGA-to-DVI adapter (i.e., the second scheme I described above). With this configuration my machine will not sleep on its own (i.e., at the time the energy saver specifies). I can "manually" put it to sleep ("Sleep" from the Apple menu). It just won't do it on its own (and none of the checkboxes in energy saver are checked -- wake for network for example -- and no active processes are running that would explain this behavior either).
Experimentation has shown that it is somehow related to using the VGA through the DVI. If I put my original configuration back (VGA-to-mDP) the machine will sleep on its own at the designated energy saver preference time.
What I don't understand is what's a DVI connection have to do with the energy saver sleep setting? The only remote possibility I can think of is perhaps the screen saver is running on both the VGA and ACD and an active VGA is sufficient to make the machine think there's activity when connected through the DVI (but not when connected through the mDP).
Of course none of this is really a serious problem. I'm only asking for academic interest.

I know I can do that but that's not the subject of this thread! I'm only asking why would a VGA connection to DVI keeps the computer from sleeping on its own.
And, oh, by the way, another audio alternative is something like this,
http://www.gefen.com/gefentv/gtvproduct.jsp?prod_id=5279
although this requires stringing a separate audio cable.

My MBP Retina doesn't allow the use of two Thunderbolt to DVI adapters. It only works with one TB - VGA adapter and one TB - DVI adapter. However now the color on the VGA connected monitor is slightly different.

The monitors are Viewsonic VA2406m-LED. The Display preferences show all three monitors but one monitor always says "No Signal" if they are both connected TB -> DVI.
The Color on the VGA connected one is slighly off. It seems like I should be able to connect two DVI monitors not sure why this is stopped. Does it have something to do with the Graphics card?

The problem was with the newEgg adapter. I just went to the Apple Store and bought an Apple adapter and the monitor now displays correctly.
For future reference, in case anyone experiences this problem:
the newEgg adapter is part number 9SIA1PU0P88920, described as a Thunderbolt Mini Displayporrt Display Port DP to DVI Adapter for APPLE Macbook Pro Air and the full description says it works for macbook pro, etc.
when this adapter is used, the macbook pro recognizes the monitor, but the monitor displays nothing.
When the apple adapter (MB507Z/B Mini Display Port to DVI Adapater) is used, the monitor displays correctly.
Of course, the individual newEgg part might simply be defective, but I doubt it. moral -- spend the extra $$ and buy the Apple adapter.

Using Keynote with USB Vga connection

I'm trying a new setup for two projectors, where I'm hooking up one using a mini displayport on an imac, connecting it via DVI, and a second one through a USB VGA connection. Previously, we were using a VGA splitter off the displayport, which kept me from having a digital connection for the one (better) projector.
This setup seems to work fine except in Keynote. I have the two projectors setup to mirror each other, while the imac serves as the main display. In other programs, the mirroring works, but in Keynote, when I activate the slide presentation, the VGA projector goes black. To my untrained eye, it appears as if Keynote is overriding the OS' display setup, and is only using the display port's connection as the secondary display.
Hope I'm explaining this well enough. Anyone have any suggestions?

In my experience, most current business projectors will display at 1024 X 768, although older/cheaper models may have a native resolution of 800 X 600. Most projectors can rescale some higher resolutions, but I'd say that you're safest to not go above 1024 X 768. Also, although some projectors will have digital inputs, many business projectors will not, and so it is vital to have the VGA connector. While you may lose a bit of quality, in the cases where you need it, you won't likely have any other option.

Both xp and windows 7 have video problems with my VGA connection using TV

To map the drive on your computer click on Start - RUN - type "\\192.168.1.1" and click ok... When prompted for Username and Password type "admin" and click ok... Now you will be able to see the folder which you have shared on your router, right click on it and select "Map network drive" and click on finish.
Now it will map the drive on your computer and you should be able to transfer the file from your computer to the USB drive.

I lecture for a living. My old G4 connected to LCD projector worked great. My new MacBookPro connected to LCD projector - the displayed images look as if I used "pastel colors" instead of bright colors. Help !

I lecture for a living. My old G4 connected to LCD projector worked great; image displayed on computer monitor is same as that projected by LCD. However my new MacBookPro connected to the LCD projector displays washed out images, as if I designed my Keynote lecture using pastel colors. Also my black & white x-ray images are blue & white. Help !

Thank you for your quick response to my question. The Apple Genius Bar tried adjusting the color settings in my MacBookPro, as stated in the document you attached. It did not help ... my Keynote lectures are still pastel, and my x-rays are blue & white. I should have stated this in my original query for help.
Again, many thanks for responding.
Did the Apple Genius explain to you why it did not work or even if it's possible?
