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.

    Hi mariab,
    What format are those music scores (I'm not familiar with cubase documents). But, it may be that Adobe PDF Pack doesn't support that format. In that case, Acrobat is the way to go. You can then print your files to PDF as you'd like. You're welcome to try Acrobat for free for 30 days to see whether it's going to work for you. If you decide it is, and you'd like to use it going forward, you could convert your PDF Pack subscription into an Acrobat subscription.

  • Using a VGA monitor with Mac Pro: DVI to VGA adaptor cord & X1900 card

    I will be purchasing the MacPro with the ATI Radeon X1900 XT. However, I want to continue using my dual Viewsonic CRT screens till the end of the year until I make the leap to a new LCD display. I know Apple sells a DVI to VGA connector and in fact I believe it to be included as an accessory.
    Here is my question:
    The graphics card I am buying (the X1900) is designated as a DUAL LINK DVI. The Apple DVI to VGA adaptor cord has a DVI -I SINGLE LINK male connector. Will this DVI-I single link connector properly mate to the female dual link connector on the X1900 graphics card? If it will, I'm probably in business. If it won't, does anyone have an idea for a workaround?
    Many thanks, John

    The DVI to VGA adapter works fine with the Radeon X1900XT (and the Geforce 7300GT and the Quadro FX4500).
    The DVI to Video adaptor works on the Radeon, but not on the two Nvidia cards.

  • Problem with my (And maybe all?) Y50 4K using an external monitor

    Specs:16Gbs of RAM512GB SSD860M 4GBi7-4710HQ/etc/ Anyhow, I finally hooked this sucker up to my monitor (Via HDMI) and was having serious performance issues in games, and other things that would be gpu/cpu worthy. I've finally found part of the culprit, which is that when the laptop screen is closed, I get bad performance, when it is open, everything is working as intended. Basically I go from this (Open lid): https://i.imgur.com/AJujwly.jpgTo this (Closed lid): https://i.imgur.com/w9uAGlN.jpg (Usually runs even slower) I suspected that the computer may be ignoring my whitelist for BF4 (For the use of discreet graphics) upon closing the laptop and switching to integrated, however, I do not believe that's the case. Lid closed while discreet graphics is forced: 15 - 25 FPSLid open while integrated graphics is forced: 5 - 7 FPS So it appears the computer just has a weird bottleneck on the GPU/CPU whenever the lid to the laptop is closed.  I have: 1. Looked through my bios2. Made sure high power settings stayed when the lid was closed/while plugged in or on battery.3. Made the computer stay awake when the lid is closed (Duh, don't know why people keep recommending this :L )4. Whitelisted the program via Nvidia's control panel to use Discreet graphics5. Tried using external monitor as extended display, and all other possible forms. All to no-avail. Anyone with a Lenovo Y50, or Lenovo Y50-4K want to confirm this issue is not just with myself? Thanks!

    I am not Y50 user but I believe it is not bizzare at all. When you think of New Approach Thermal Design™  the producer is introducing in their recent models (link, link - look at the Temperature section) I can bet lot of heat dissipate up through the keyboard. Closing the lid you actually stop (or severely reduce) that heat dissipation  This can cause throttling issue.

    Can I attach my HP monitor w1907 to Mac air with a DVI cable?

    You need to use a DVI to Mini DisplayPort adapter; for a 30-inch display, the adapter needs to be dual-link.

  • 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.

  • Two VGA monitors don't work with two different G4s, but both work with G3!

    I recently acquired two used Power Mac G4s (one of them is a mirrored-door dual-processor that I got from school and was told should work, the other is a Gigabit Ethernet model, and should also work), from two completely different sources. They both turn on (I get a power-on light, I hear HDDs churning, and I get a power chime from one of them, and they react to the usual Mac stimuli, mouse and keyboard light up, reset button works, etc.) but I get *absolutely no video*. The monitor syncs for a second, like it gets a quick signal, then goes immediately back to the "CHECK SIGNAL CABLE" message.
    I have tried them both with two generic PC VGA monitors (though they were both kind of old and crummy ones, they work on my G3 and other computers. I've tried the working PCI video card from my G3, that doesn't work, nor does swapping their video cards. They both have Apple-supplied ATI AGP video cards, both with Apple's proprietary ADC interface, though one has only DVI out (with a DVI to VGA adapter that came with it) and the other has a straight VGA port.
    The weird thing is that, even though these computers have never, er, met before, they have the exact same problem. The only thing these things have in common is the monitor I'm using. This leads me to believe
    The only thing left I can think of is to hook them straight from the DVI port to my HDTV, but I don't have a DVI cable, much less know ANYTHING about DVI. Could it be that these particular VGA monitors don't like AGP video cards, or some sort of weird incompatibility that isn't well known?
    I figure if anyone's seen something like this, you guys have. Here are the AppleHistory entries on these machines, if it helps:

    The software on the hard drives may be set for a video setting that won't work with your monitor. A few things to try (in order):
    1) Reset PRAM. Hold down Cmd-Option-P-R when booting until you hear the third Boing.
    2) Hold down Option when booting. Should show symbol of hard drive, plus a couple of arrows.
    3) Boot from a CD (Install disk or, preferably, Hardware Test Disk).
    4) Safe boot. Hold down "S" just after the boing. Release it when (if?) you see the turning gear.
    If it is a scan rate problem, one of these should show some video.

  • Video cards with 2 dvi output ports compatiable with hpe h8-1234

    I need a video card that will support 2 dvi monitors and be compatiable with a hpe h8-1234  desktop.  Please help

    Hi,
    The current video card in your PC will support two DVI monitors. Just use a HDMI to DVI cable with one of the monitors. Your video connection possibilities are: one analog DVI monitor and one digital monitor or two DVI digital monitors.  For best results use two digital monitors.

  • Connecting a vga monitor to mini displayport with 2 adapters

    Hi. I have a 21.5 inch iMac and I want to attach a second monitor. The monitor that I bought, the MultiSync LCD1560m, says it is mac compatible. it has two inputs; one DVI-D and one VGA. The monitor came with a vga cable, but not a DVI-D cable. I bought a dvi to mini displayport adapter, thinking the monitor would come with a DVI-D cable. I also had a VGA to DVI cable laying around, and attached that to the other adapter. The iMac won't detect the monitor. The chain from the iMac to the monitor is as follows: Mini DisplayPort > DVI > VGA. I don't want to shell out $40 for a new DVI-D cable. I've already rebooted multiple times plugging and unplugging the mnitor in before and after the iMac started up. I've also reset the PRAM. Does anybody have a solution that doesn't involve spending (much) money? (I'm broke. my monitor only cost $75). Thanks.

    $40 for a DVI cable, where are you shopping Macy's?

  • 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.

  • OK if I go with a Mac Pro instead of the new iMac will common monitors work

    I have two HP w2007 22 inch Digital Widescreen LCD monitors, can I get by with these for six months until I can buy better displays.
    I want to edit video with the New Full Suite of Final Cut Studio Pro 3.

    Most of the newer MacPro models have one dual-link DVI port and one mini-display port. So you may need a mini-display-to-DVI adapter if you plan to use two monitors.

  • External VGA Monitor with MBP

    I'm contemplating buying a MBP 15" and was wondering if I could attach an external monitor (older model - Samsung SyncMaster 175V) for use in my home office and get good results.

    Well, it's hard to say. Factors such as resolution, refresh rate, even size can make it look a little different than what you have on your screen. Since it's not DVI, the colors may be a little different, probably not as rich as your MBP screen. If your resolution is lower than your MBP, it might have a smaller screen area, and make your icons look a little bigger than normal.
    There really shouldn't be any driver issue at all. Just plug it in, and tell your MBP to go to your external monitor, it should show almost right away. You have the adaptor right? There's only one way to find out if you'll like using your external monitor on your MBP, and that's to try it out. You have nothing to lose..

  • Trying to setup RAID 1 with new SATA drives on xserve 2009 model

    Trying to setup RAID 1 with new SATA drives on xserve 2009 model
    I have an Xserve rack mount model Xserve 2.26 Quad Core (EMC# 2279) with an Apple RAID card, 24GB RAM (running 10.9 Server software)
    Purchased two Western Digital 1TB SATA III 7200 RPM 64MB Cache Black WD1003FZEX drives
    It came with three 160GB SATA drives.  I'm leaving one of the original 160GB drives for the OS, but I want to replace the 2 other drives and set it up with RAID 1 (mirrored). I bought 2 brand new Western Digital 1TB SATA drives and formatted them on another Mac through Disk Utility with Mac OS Extended (Journaled) formatting.  I then placed the new drives in the Xserve and booted it up.  After I login it immediately gives me 2 error windows saying...
    "Apple RAID Card
    The Apple RAID Card installed in your system requires your attention."
    It has two buttons underneath this message allowing me to either select 'Ignore' or 'Open RAID Utility'
    I've tried to RAID the drives the Disk Utility and through the RAID Utility with no success.
    I have both drives mounted on the desktop, as separate drives, but I really need to set these up as a RAID 1.
    I've been reading other forums, where others have been able to get this to work by using a jumper on certain pins (5 & 6)of the drive to back down the transfer rate to 1.5 Gb per second.  I tried that and it didn't work for me. Maybe I used the wrong pins -- I just don't know.  I'm also wondering if there is some Apple firmware that is required on these drives?  I'm asking for help from anyone who has gone through this same issue.  Thanks in advance.

    UPDATE --  I had an issue with the RAID card battery, it was dead and I have since replaced it.  But I am still unable to setup the RAID 1 drive configuration.  Does anyone know if it has something to do with the faster transfer rates on these new drives.  Maybe they need to be clocked down with certain jumper settings on these Western Digital drives?  Or am I fighting a losing battle because these drives don't have Apple firmware?  Any help would be appreciated. Thanks.
