Mac mini 2009 . Mini DVI - VGA adapter with Monitor LG L1953S . No sleep .

Hi ..
Yesterday i started in the fabulous world of MAC with my brand new MAC MINI . The problem that i have is that when the MAC mini is in stand-by the monitor is not in sleep state , and i get in the monitor screen " check cable " . So i have to disconnect manually the monitor when mac is in sleep state .
I am using mini-dvi to vga adapter (original mac ) .
¿What is the problem ?
Thanks a lot ...

DVI-I provides the direct Analog signals needed to get VGA using a very simple adapter.
DsiplayPort (and its Mini variant) requires a converter to produce VGA or Dual-Link DVI, and the converter must be active/powered. There is a lot of logic in those converters. It may also have additional limitations.
In general, you should hook your highest resolution, most demanding display up with the DVI to VGA adapter.If running two Mini DisplayPort displays, ALL MiniDisplayPort converters must be active/powered.

Mini Display Port to VGA adapter with Mac Pro

Just as a word of advice if you're thinking of buying a new Mac Pro and planning on hooking it up to dual VGA displays at their native resolutions - don't.
Apple claim it will support 3 VGA displays. That might be true in a very loose sense but not in the sense that you'll actually be able to work with it.
My experience (all using same adapter, cables and monitors):
*Mac Pro - Dual screen set up*
1 x LG Flatron W2242S connected via DVI > VGA adapter - offers native resolution (1680x1050)
1 x LG Flatron W2242S connected via Mini Display > VGA adapter - does not offer native resolution
*Mac Pro - Dual* screen set up*
1 x Iiyama E2472HD connected via DVI - offers native resolution (1920x1080)
1 x Iiyama E2472HD connected via Mini Display > VGA adapter - offers native resolution (1920x1080) but displays it pillar boxed (i.e. squashed)
*MacBook Pro - Dual screen set up*
1 x laptop screen - fine (obviously)
1 x LG Flatron W2242S connected via Mini Display > VGA adapter - offers native res (1680x1050)
The conclusions being that despite having the exact same configuration in terms of adapters and monitors my £3k Mac Pro is incapable of doing what my MacBook Pro can.
I have spoken to Apple about this and they have admitted it is a limitation and suggested buying DVI monitors along with the Dual Link DVI adapter (£70).
Not ideal.

Will the mini display port to vga adapter work with a 2007 mac book?

I think your Macbook came with a Mini DVI port instead of a Mini Display port.

MacBook Pro(Mid 2012) Can't connect to my Dynex TV with mini display port to VGA adapter

I have a MacBook Pro(Mid 2012, running OS X 10.9.4) and I recently just bought a mini display port to VGA adapter so I could hook it up to my dynex TV but when I connect everything my TV says no signal. Do I need to do something in settings?

Mini port display to vga adapter won't work

Hi,
since I upgraded to Maverick I haven't been able to connect to my projector via the miniport display to vga adapter. It all worked before that.
I need to connect to the Interactive White Board for my work and it really annoys me. I'm forced to use a windows computer. Can you help me?
Have you considered fixing this problem, which is complained by many as far as I know?
Thanks.
El3na.

By any chance were you using a VGA->DVI adapter when trying to use the Mini-DisplayPort->VGA adapter? As in Mini-DisplayPort->VGA->DVI?
I had trouble with this. I found going straight to Mini-DisplayPort->VGA or Mini-DisplayPort->DVI worked perfectly but once I added a VGA->DVI or DVI->VGA adapter to the chain the screen would be detected by OS X but the monitor itself would give the "No signal detected" message. I tried all these combinations on the same monitor.
Not sure if it helps your situation but I have noticed some similar issues.
EDIT: Oh, and I have the new MacBook Pro 15inch with Retina all fully updated. I noticed that with my late-2009 White Macbook didn't have this issue with the cables and adapters.

Can I use a mini display port to VGA adapter and then a VGA to av adapter to connect my MacBook pro to my standard definition tv?

No. You need a converter box like this to go with your MDP-VGA adapter:

18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

How can I detect displays?
If the detect displays option is not available, hold down the Option key while you are in the Display pane.
How do I select additional resolutions on my display?
You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
I hope this information helps ....

No widescreen modes available using dvi-vga adapter

I have a sony gdm-fw900 24" widescreen CRT monitor and just bought a new mac mini (1.66 dual core, 1GB etc). For some reason the mini does not detect that this is a widescreen monitor so all i get are standard 4:3 resolutions in the display system preference. I'm connecting through the standard white dvi-vga adapter that came with the mini.
Is there a way to enable other resolutions? I want to run it at 1920 x 1200
Thanks in advance,
Shay
Mac Mini 1.66 Dual Core Mac OS X (10.4.7)

Thanks for the expertise, its just that I'm buying a 26" Sony Bravia for my bedroom when I save up enough which will serve for my Mac Mini, (via vga), and for my PS3 (via HDMI when it is released). It would be ideal for the Bravia to have a DVI connection of that of a monitor, however I still think that VGA is a sound connection as I have seen in pictures off 123MacMini.com of users having connected that way.

Mini DisplayPort to DVI-D adapter works with Mac Mini 2010?

Hi,
I would like to connect my Mac Mini (2010 edition) to both my Samsung PX2370 display and my LCD TV. Currently, I only have the Samsung display connected through the included HDMI-to-DVI adapter, but I'd like to use the HDMI output to directly connect my LCD TV, and connect the Samsung display by using a Mini DisplayPort-to-DVI adapter, like the one that is for sale at the Apple Online Store. Such adapter should work without trouble with any MAc computer that has a mini DisplayPort output, including the Mac Mini, right?
Thanks in advance for your support.

You're right, but I forgot to mention that the Samsung display is just an LCD monitor, so I don´t really need to get audio output for both connections
Currently, I use an HDMI-to-DVI adapter to connect the Samsung monitor, but I'd like to use the HDMI output to connect my LCD TV instead (and probably a home theater system in the future), and use the Mini DisplayPort output for the monitor, so that I can have a dual-display setup.
I asked this question, because I read the description for the Mini DisplayPort-to-DVI adapter in the Mexico Apple Store web page, and that description tells that only Macbooks support the adapter. In the US Apple Store page, it does tell that the adapter is supported by any Apple computer with a Mini DP connection, so I just wanted to confirm which description is true, to avoid confusions.
Anyway, I appreciate that you took the time to respond... Regards!!

No video with mini dvi - vga adapter (2007 Macbook)

Connecting an external TFT display (Nokia 500 Xa) to my MacBook's mini dvi port with a mini dvi to vga adapter, there's no video.
Any ideas about what might cause this? the monitor is a bit old, but VGA should still be the same, eh?
I thought maybe it's the adapter's pin configuration... What exactly does the adapter let through?
Grateful for any ideas.

How do you configure a newer Mac mini to use a VGA adapter?

I don't know what could be wrong the computer was fine with DVI but my tv isn't hdcp compliant and won't play rentals or netflix over dvi, so I need to use VGA adapter. My Panasonic display is set to rgb mode, but I tried all modes. Already tried rebooting. Any advanced settings for changing the Mac mini output to rgb? Any other ideas on why no picture at all?

Thanks tried that already-gonna try on a newer monitor. Probably time to let go of my old time plasma display but it's hard-still looks great and it cost 4 grand but I could get something comparable for 6-8 hundred now

Mini Display Port to VGA Adapter Having Issues with My Samsung 40" HDTV

So I ordered the brand new 15" i7 Macbook Pro along with the Apple wireless magic mouse and wireless keyboard after having bought my HDTV (went on a bit of a spree) with the intention of using the TV as a monitor for couch surfing. But, upon hooking up the adapter to the TV, my macbook's screen flickered between that blue transitionary screen and it's desktop screen. It did this for a few minutes. I jiggled the cable thinking that there was a loose connection somewhere as that was the problem with my previous mini DVI to VGA adapter from Apple. I did a little research and it turns out that they released a firmware update in 2009 for such a problem. I downloaded the update and attempted to install it but it did not determine that there was even an adapter connected. So, I proceeded to call Apple, they man was very calming to talk to and make all of my problems seem to melt away, but there were no solutions reached. He thought that maybe my TV either had a problem or was incompatible with the adapter (incompatible with a VGA connection? can you get any more analoge that that?). So, here I am, the adapter seems not to have a problem with regular monitors but I am still experiencing intermittent disconnects from my TV. I still, superstitiously jiggle the connection whenever I have dropouts but that really doesn't seem to be the issue here (or at least I hope not because that could mean port issues with my new laptop). Any suggestions? I noticed, after changing some settings on my TV, in an attempt to remedy this, that the TV was displaying the picture funny, I turned the TV off and then on again and it fixed the problem. That being said, perhaps I just need to turn my TV completely off when I'm not using it, as I have been just letting it go into standby. Maybe it needs a restart every so often much like my computer. I don't currently have data to support that theory as I just recently tried turning it off, but, since then have not had dropouts.

You may have the screen refresh rate set higher than the TV is generally able to track reliably. It may be able to get there most times, but occasionally loses sync because it is out of its nominal range.
I suggest you sit down with the manual for the TV and find out what resolutions at what refresh rates it intends to support through VGA, and make sure your screen settings are near (or below) those limits.

Mini DVI -- VGA Adapter

When you insert the adapter into the iMac...isn't the screen supposed to flicker and adjust or something? When I plug the appropriate VGA adapter into my MacBook Pro, the screen flickers and adjusts and sends a signal just fine. The iMac - not so much. No reaction at all to having a mini DVI to VGA adapter plugged in. The result of this is no image appearing on the tv. Is there a way to test the mini DVI port on the iMac? Unfortunately, the only thing I may be able to do is find someone else with an iMac and try the adapter on their computer.

Hi BMBell1919
Do it the other way around!
1. Connect the VGA cable to the TV.
2. Connect the Adapter to the VGA cable.
3. Then connect the Adapter to the iMac.

Mini Display Port to VGA adapter + Monitor Eizo s2231W = CRASH

I purchased a new macbook pro last month with 2 adapters, one for VGA the other for DVI. I'm having some trouble with the Mini-DVI to VGA adapter. The Mini Display Port to DVI adapter works well.
When I attach the VGA adapter to the monitor it works well for a couple of minutes, then I dont know why my MBP crashes and I can see a purple or white screen. The crash is really a crash... cauz I cant do anything. My mac is frozen and the only way to resuscitate him is to keep pressed the power button for a while till it turns off, and then turn it on again.
You can say... why do you need the VGA if the DVI works...
the problem is that I'm probably supposed to use it one day attached to a projector because of a presentation at university.
So I dont wanna see my new macbook pro freezing in front of my professor.
please help.
EDIT:
adding some precious information
My hardware configuration as regard the graphic chipset is
NVIDIA GeForce 320M
The resolution of the external monitor is 1620x1080
I'M NOT using the mirroring ( but the desktop extension)

I had the exact same problem. It actually escalated from there and it would crash at the startup screen (the white one with the apple and the spinning gear). The only way I was able to fix this was to reformat the entire computer. I was lucky enough to have backed up all my data when it first started crashing. I've only reformatted yesterday and things seem fine for now. I don't know what caused it, or how to fix the problem any other way.

Mac Mini 2009 won't display on Acer Monitor P166HQL

I'm currently living in Brazil and due to continuing problems with my 2006 MBP running 10.6.8, I've just bought a 2009 Mac Mini which apparently is running Mavericks. The display works fine with the MBP using a DVI-Serial connector [the monitor only has serial]. When i connect the monitor to the Mac Mini I need to add a mini DVI to DVI connector into the equation. so the chain is...
MacMini / miniDVI to DVI female / DVI male to Serial female / Serial male to Serial male / Acer Monitor
i have followed the tip Troubleshooting: Mac mini displays no video but nothing there helped a resolve. Buying new cables for the mac will be a difficult exercise where i am. I'm going to start out by tring any other monitors i can find as well as televisions.

Correction - the chain is...
MacMini / mini Display port to DVI female / DVI male to Serial female / Serial male to Serial male / Acer Monitor
