Lost max. VGA monitor reoslution on upgrade to G5

Recently upgraded to G5 with nVidia GeForce 7800 graphics card. Now I cannot achieve a resolution over 1024 x 728 on my Sony GDM-F520 monitor even though it is rated to max. resolution of 2048 x 1536. I need the higher resolutions for photo work and don't see a Cinema Display as a suitable alternative. Changing refresf rates does not help. Any suggestions?

Resetting PRAM did the trick!

Don't setup an XServe with a DVI monitor if you intend to use a VGA monitor

Hi Forum Folks.
A bit of a "gotcha" to warn others about, with XServes, and VGA vs DVI monitors.
We Recently re-setup (erase + install a fresh OS) on a 2008 XServe Xeon, with a DVI (Digital) monitor connected. All worked fine, and we went to move the server into the production environment.
However, when we moved + plugged the XServe into it's new home (a rack), it would not boot (flashing question mark).
Moving the Xserve out of the rack, and back to it's work-bench setup, made it work again.
We traced the problem to the monitor we used... If we hooked up a digital (DVI) monitor, the XServe worked fine (with the mini DVI to DVI connector). If we hooked up a VGA monitor (with a mini DVI to VGA connector) that's when the XServe wouldn't boot. We tried a variety of common techniques to solve the problem, including resetting various settings, re-installing Mac OS X 10.5.6 Server over the top etc.
The solution:
(Although I'm sure there are simpler solutions):
We setup the server again (from scratch) using the VGA monitor combination from the very start of the setup, and all worked fine (on VGA or DVI monitors). The server is happily in production now, with it's VGA output.
So the lesson here: Always set up your XServe using a VGA-based monitor in the first instance.
Hope this helps someone else.
Cheers,
Derek

So the lesson here: Always set up your XServe using a VGA-based monitor in the first instance.
... or don't use a monitor at all
I don't think I've ever used a monitor when setting up a server - maybe used a KVM if I've re-installed or upgraded the OS, but for the main part every install I do is run remotely.
Still it's good to know, especially since it defies logic.

VGA monitor and a 2010 Mac Mini - HELP PLEASE!

I just upgraded from the early 2009 model where all you needed was a VGA to mini DVI adapter. With this 2010 model, Im not sure if thats possible (for cheap anyway). I have a VGA monitor and all I want to do is hook it up to the new mac mini ...but how? I've heard that because VGA is analog and HDMI is digital that it cannot be done for under $100 ..is this so? why oh why couldnt apple have stuck with mini dvi. Please someone advise how to do this ..or am I forced to buy a new monitor with DVI/Mini DVI/HDMI connections

Forget the HDMI port. There's the Mini DisplayPort available, and all it takes is the right adapter:

That should solve your problem.

You can upgrade to Snow Leopard, Lion or Mountain Lion (coming next month), but you need Snow Leopard to upgrade to Lion or Mountain Lion. Check this web to know how to add memory to your computer and the memory that it supports (probably, 3 GB).

Mac mini late 2012 not working with small VGA monitor

I got a mac mini (late 2012 10.8.4 all updates installed) and it is working fine with samsung b2230 via VGA adapter. There is a small VGA monitor (PL8006 max at 1024*768) which works fine when connected to a PC.
When I connect the small VGA monitor to mac mini it is not displaying anything (monitor shows blue screen with letters VGA so I assue it is not getting any signal). Mac's resolution is set to 1024*768 with 60Hz (even tried with 800*600 without any success). Monitor is also not working with win 7 installed in mac mini using bootcamp.
Any thoughts?

i just found that when the VGA cable of the small monitor is slightly inserted into the VGA adaptor it works fine (this is not usable because there is no way to keep the pins at that level) and when the pins inserted fully / moved little it is not working. Since this happens only between these two devices can't find which one is faulty.

Why do Apple change everything all the time?

You need an adaptor, HDMI to DVI is included in the package, take HDMI to VGA or thunderbolt which, in case of monitor, is the same as minidisplay port to VGA. Apple has always upgraded the best output port, unfotunately monitor manufacturers have not done the same.

Jaguar refuses to display on external VGA monitor

Hi,
I have a PowerBook G3 that I would like to set up for printing. I installed OS 9 on it and it displays just fine on my external VGA monitor. I also tried installing OS 10.1 on it which seems to work fine but when I try to install OS 10.2 the monitor goes off after the disk loads up (after the Apple logo goes away). It will not display on my monitor and I cannot use the built in display since it's broken. What's wrong?
Thanks

Apple Rules,
Did you make sure to download the firmware update (if you PowerBook G3 is a firewire model) before upgrading.

What type of disk is the 10.2 Jaguar disk that you are trying to use to install? Is it a machine specific disk or a full retail install disk?

Additonal VGA monitor showing in Display properties.

I have a problem, I am currently running Window 7 Pro 64 and when i restarted my laptop it now has an additional monitor showing in the display properties. I do not have an external VGA monitor connected to it, and I have tried to remove the
display adapters in hopes of remove the additional mystery monitor, but after removal of the display adapter drivers and a reboot the extra monitor comes back. Can anyone help?

Hi,
According to your description, the hardware driver is also related to the BIOS of your computer, to confirm this, try to start the computer in safe mode in the way below:
Safe mode starts Windows with a limited set of files and drivers
Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
Click the Start button Picture of Start button, click the arrow next to the Shut Down button Picture of Shut Down button, and then click Restart.
Do one of the following:
Restart your computer, press and hold the F8 key. You need to press F8 before the Windows logo appears.
On the Advanced Boot Options screen, use the arrow keys to highlight the safe mode option you want, and then press Enter.
Log on to your computer with a user account that has administrator rights.
You can refer to this for more details:
http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7
If this works for you, the BIOS should be upgraded, go to the official site to upgrade the BIOS accordingly.

How to get two vga monitors on a mac mini 2012

Hi Guys,
please forgive any ignorance that follows. I am a new convert from a PC and have bought a Mac Mini 2012. I want to be able to use a monitor that I can see my music programme but run a second monitor that will allow me to display visuals from a VJ programme. Here is my journey.
I bought the mac mini and the thunderbolt to vga adapter. Generic VGA monitor - worked a treat. I then wanted to run a second generic vga monitor form the hdmi port. After a lot research I chose an adapter for £15 that one of the reviews said worked perfectly for a mac mini and VGA. Bought it form Amazon. Didn't work - no signal etc - refund. Then I thought I would buy a monitor / DVD with a HDMI cable and do hdmi to hdmi and use that as the music monitor and use the thunderbolt port for the projector and VJ programme. Bought one from Asda. Plugged in great picture etc worked a treat but got a ground hum from new HDMI monitor. More research and realised that ground hum was a nightmare. HDMI monitor back and refund.
It is doing my head in.
I will be a happier man if someone could say that they have a mac mini 2012 and they bought this HDMI VGA converter and use a generic vga monitor and it works a treat. There is only so much stuff I can return before my lick runs out.
I don't think I'm asking for much.
Any help would be gratefully received.
Cheers Pete

Sorry, but I can not safely suggest a digital HDMI to analog VGA converter or if any would even work with the Mac Mini because I do not have and have not personally tested any.
I can only suggest that instead of dropping more money into adapters or an HDMI to VGA converter, that perhaps' you should consider replacing one if not both with a more modern digital monitor that support either HDMI and/or DVI.

How to connect VGA Monitor via Thunderbolt Display

I've been using my Macbook Air mid 2013 with a Samsung monitor connected via the Mini Display Port to VGA adapter. I've now bought a 27" Thunderbolt display, which I've connect to my Mac, and assumed I could now daisy chain my samsung monitor into the Thunderbolt port in the back of the monitor. This isn't working.
Is this expected behaviour? Some people have said online that it will work if there's some other Thunderbolt peripheral between the Thunbolt Display and the VGA adapter, but I don't know what kind of peripheral they mean.
Apple support says that my model Macbook air can power two external displays.
How can I get this to work?
Thank you

I want to know if I can connect a vga monitor to the quad by simply getting a vga to dvi adaptor.
Yes, you can.

Can I use a Mac mini with a VGA monitor?

The Mac mini web page lists an Apple Mini DisplayPort to VGA Adapter as an accessory, but the Mac mini doesn't appear to have a Mini DisplayPort.
The Mac mini also has an HDMI to DVI Adapter included, but would this allow a VGA monitor to be connected via an additional DVI to VGA cable? ie. can the HDMI port provide an analogue signal that a VGA monitor can receive?

Some Mac Minis do have mini-DisplayPorts. In these two it is between the HDMI and the USB ports:
(yes Thunderbolt should accept mini-Displayport).
In this one it is between the Mini-DVI and the USB ports:
Only the oldest Intel models would you need a different adapter to VGA
Those you would need a DVI to VGA adapter from Apple such as this one. Note, DVI to VGA is converting digital to analog, and not very useful, unless your TV has neither DVI nor HDMI. DVI is much better converted up to HDMI. And the audio would have to come in separately. So depending on your display model and make, you may be asking for the wrong adapter. VGA is fine if all you are going to do is view DVDs on an old TV. But if you want the ability to use the Dock, menubar, etc..., it is good to have a 1080p TV with built-in HDMI or better.

No signal to VGA monitor using Mac mini display to VGA adaptor and first time boot Mac mini

Just unpacked Mac mini and powered up using Mac mini to VGA display adaptor and VGA monitor. There is no signal to the monitor ( power is on).
How to see the display?

[ 13.093] (==) No Layout section. Using the first Screen section.
[ 13.093] (==) No screen section available. Using defaults.
[ 13.093] (**) |-->Screen "Default Screen Section" (0)
[ 13.093] (**) | |-->Monitor "<default monitor>"
[ 13.093] (==) No monitor specified for screen "Default Screen Section".
Using a default monitor configuration.
First step would be to create the necessary entries (easier to make a complete xorg.conf versus xorg.conf.d/##-whatever.conf).
All Desktop Environments / Window Managers rely on X. Man pages are helpful, possibly some headaches ahead as I fought a dual-monitor display this way.
I currently run a xrandr script to switch displays on my hp pavilion: https://wiki.archlinux.org/index.php/Xrandr#Scripts

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.

Can I use the Apple ADC to DVI adapter with a VGA monitor?

Hey everybody,
I have a quick question. I work on computers fr friends and family as a hobby. I have an ADC monitor and need ot be able to hook up computers with a VGA port on them to it. Can I use the Apple ADC to DVI adapter along with an Apple DVI to VGA adapter to successfully connect VGA computers to my ADC display? I was assuming this would work and ordered both adapters but now I have made myself nervous about weather or not this will actually work. Has anybody out there successfully done this? Thanks for your help in advance everybody.

You can't run an ADC display with a VGA computer without a converter. Adapters won't do it.
a VGA to ADC converter will drive the ADC display directly
<http://www.gefen.com/kvm/product.jsp?prod_id=1301>
If you have the Apple DVI to ADC adapter
<http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=18 72D402&nplm=M8661LL/B>
you could use it with a VGA to DVI converter
<http://www.gefen.com/kvm/product.jsp?prod_id=1310>
It might be cheaper to get DVI graphics boards for the computers and use the Apple DVI to ADC adapter.
<http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=18 72D402&nplm=M8661LL/B>
Your title says "Can I use the Apple ADC to DVI adapter with a VGA monitor?". If you want to connect a VGA monitor to a computer's ADC port you need the ADC to VGA adapter
<http://www.gefen.com/kvm/product.jsp?prod_id=1299> You can't use an ADC to DVI adapter followed by a DVI to VGA adapter, because the ADC to DVI adapter doesn't pass the analog video signals needed for VGA.

How do you plug a VGA monitor to a Mac mini (mid 2011)

I used my older Mac mini (mid 2007) with a VGA LCD monitor through an "DVI to VGA" adapter with no problems.
However, this older adapter does not fit in the "HDMI to DVI Adapter" supplied with my new Mac mini (mid 2011).
There are no receptacles (holes) in the "HDMI to DVI adapter" for the four pins located around the flat tab on one hand of the older adapter .
Any suggestion on how to plug a LCD VGA monitor to a mid 2011 Mac mini?
I know there is a Thunderbolt port and a HDMI port,
but being able to use an inexpensive VGA monitor for set-up and periodic maintenance,
without having to fire up a huge plasma screen each time, would be nice.
There is no displayport on this mid 2011 Mac mini.
There does not seem to be any HDMI to VGA nor Thunderbolt to VGA adapters on the market.
Any suggestions?

The > Apple - Thunderbolt Port is the same as and doubles as a Mini DisplayPort.
Look down at the bottom of > Mac mini (Mid 2011) - Technical Specifications in the Accessories / Displays and Graphics section or on page #33 of your User Guide.
