Apple LC475: Connecting a PC monitor?

Hi
Back in 1993, I bought my first Apple - a desktop LC475 (Performa xxx) with an Apple display. It was retired in the late 90s but I kept it for old times sake.
I switched it on yesterday for the first time in 10 years maybe and it seemed to boot up just fine - familar welcome note sounding - but the monitor remained black despite the power light glowing green.
I'm now not sure: is the computer itself ok? Is the monitor broken? I've got a PC monitor in the house (15in VGA flatscreen) and want to know how I connect it up. Research suggests the video out on the LC475 is DB15 if that makes sense.
Anyone got any ideas?

Hello,
a new hard drive with system 7 installed. I hope that'll fix matters.
According to the technical specifications, the LC 475 needs at least System 7.1 and a System Enabler 065 (the specifications for the Performa 475 list System 7.1P3 and System Enabler 364). No need for system enablers with the newer operating systems mentioned.
I don't have a Mac with a floppy drive
If you have (or could borrow) a Windows PC (with a floppy drive), it can be used for the Network Access Disk 7.5 download, but would require (Aladdin) StuffIt Expander for Windows and a suitable PC disk image utility.
Normally, never decode or decompress Mac program files on a PC. Always keep MacBinary (.bin) or BinHex (.hqx) unaltered until on a Macintosh computer.
BTW, a full System 7.5.3 is available for download from Apple (e.g., British and North American versions). The downloadable System 7.5.3 files are small enough to be transferred on 1.44 MB diskettes (in this case, a plain copying process; no separate disk image program needed). A startup floppy file is not included (use the Network Access Disk 7.5 whenever necessary).

    I've just bought a Pro Retina. As far as I know this is the only one which will connect 2 external monitors running different programmes ie not cloned.
    You use the 2 thunderbolt ports for the DVIs (if they're not Apple monitors)
    You need 2 thunderbolt to DVIs. MiniDisplay port to DVI might work too (MIGHT WORK! Not sure yet) and these are a lot cheaper.

    I want to connect an HDMI monitor to my MacBook Pro to use as my second monitor. I need to know what type of cable to use? I use iPhoto and iMovie extensively and it would really help to have a second monitor. Which port on the MacBook would I use?

    If your MBpro has a MiniDisplay port or Thunderbolt port then you buy a MiniDisplay port to HDMI adapter and a HDMI cable. (The adapter will plug into the Thunderbolt port).

  • DVI connection to second monitor doesn't work

    When I had the connection from my Mac Pro to my two monitors (20" Cinema display and 19" Princeton monitor), I had the black screens for a few seconds for both monitors then return to normal. It happens anytime. I read the forum and changed the VGA cable to connect the 19" Princeton monitor and now both monitors work fine.
    Do I have to live with the VGA cable option or anyone know how to utilize the DVI connection capability of Mac Pro please help?

    Hi Joe,
    I tried to locate the right slot (x16) by going to
    Expansion Slot Utility and changed from #1 to #2. It
    showed my configuration of the PCI card now is x16 or
    fully speed.
    The problem is still the same with DVI connection to
    two monitors. Any other suggestions would be
    appreciated.

    I'm fresh out of idea's. I assume that your card is a 7300GT, correct? I had an out of the box failure with mine and Apple replaced it. I was lead to believe that there were quite a few failures with the card. Interesting, they didn't even want the old one back.
    I'd go the Applecare route next and see what they say. FYI, I have two of these running three monitors (all apple flat panels) all on DVI connectors.

    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.

    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.

  • MacBook Air mid-2013 OSX 10.9.1 cannot connect to DVI Monitor

    Does anyone else have this problem?  I've seen similar issues raised, but so far can't find a solution to my particular issue:
    MacBook Air Mid 2013 (ordered Jan 2014)
    - 1.3GHz Intel Core i5
    - 8GB 1600MHz DDR3 RAM
    - OSX 10.9.1 Mavericks.
    When I connect my MacBook Air to any monitor (well, I've tried three monitors: Benq, NEC and Samsung) the monitor will not detect an attached computer. The MacBook also does not think it's connected to an external display.
    If I connect via VGA cable, it works fine most of the time*, so the display port seems to work only for VGA and not DVI.
    I am using mini display port adapters (DVI and VGA) purchased from the Apple Store.
    The adapter for the mini display to DVI works fine, since I can get my 2009 MacBook unibody to connect to an external display via DVI without issue. So it's not the adapter, or the DVI cable.
    I have tried resetting the System Management Controller for my MacBook air but it does not work.  No matter how many times I reset the computer (Hard reset, Soft power down, SMC reset) I cannot get it to connect via DVI.
    Has anyone experienced this issue, or seen a resolution for it?
    *The only other symptom I get periodically, is that after being disconnected from a VGA monitor, the computer will periodically (about 2/5 times) not connect to the VGA monitor either without a reboot.   However it will connect most of the time, and ALL of the time after a reboot.
    Thank you

    Thanks themachead: I have tried the adaptors on different macs, as I indicated in my post.  The adaptor works fine with a different mac
    Yes, I have also tried starting up with the monitor connected, and disconnected.
    I just got off the phone with Apple Care. They couldn't solve my issue through normal means, but during one attempt, we closed my MacBook Air while it was connected to the external display, with my Magic Mouse and Apple Keyboard connected via Bluetooth.  The external monitor did not come on.  However when I opened my Macbook Air's screen, we saw that my Mac had crashed and prompted me to reboot. When it did, the external monitor worked.  I have been able to disconnect and reconnect the monitor and it seems to be working now.   I will see what happens after a few attempts.

  • MacBook Pro Retina Wont Connect back to Monitor

    Hey Everyone,
    I have a MacBook Pro Retina Early 2013 15in that is running OS X Yosemite - 10.10.2 - Graphics Card: NVIDIA GeForce GT 650M 1024 MB
    At Work for the past 1.5 years i have been connecting to a Dell Monitor via a DVI to HDMI Cable to use as my primary screen and have never had any issues. During the day I often present on the projector in the BoardRoom a Dell 4610X using a direct HDMI cable.
    The issue: Ever since I have updated my laptop to Yosemite, every time i connect my macbook to my monitor after its been connected to the projector it will no longer connect. The monitor will recognize that there is something connected but it wont show anything. Even if i try another display in the office the same thing happens. The issue will always resolve if i restart the computer.
    Recently I had an issue with the Logic Board and it was replaced by an Apple Certified repair shop. This issue was happening even before the logic board was replaced and it is still having the same issues now, so I don't believe its an hardware issue.
    Although this issue is not critical, its a nuisance to re-start my laptop each time i get back to my desk after a meeting in the boardroom...
    I would high appreciate some help on this!!
    Thanks in Advance

    Something else to check ..
    Open System Preferences > Network then select the Wi-Fi tab.
    Drag the school wi fi network name to the top of the list.
    You can open System Preferrences by clicking the System Preferences icon in your Dock
    Or click System Preferences from your Apple menu icon top left in your screen.
    Or, from your Applications folder.

  • How do i connect three external monitors to a macbook pro?

    How do I connect three extrenal monitors to my Macbook Pro?

    I have a USB to DVI adapter from kensington. I use to use it to power at 14" display.Moving windows around had some tearing and lag. Typing lagged, but it was use-able. It was fine for displaying diffrent stats. The OS treated it as it would any additional display.
    But I found it undesirable for any thing tha requires lots dragging and clicking.
    Every so often the device would lock up. At witch point the computer would get stuck trying to detect the USB display. I would have to unplug the adapter, cycle the power on the adapter. And then it would be good for a couple more months.
    Also some times after a reboot, the adapter would stop working. I would have to unplug it, and login, and then plug it back in.
    Coping file to my USB 2 harddrive seemed to cause more lag to the USB to Video Adapter.

    Normally, you just connect the monitor to the MacBook using a VGA adaptor that you can buy from an Apple Store.  Now try System Preferences > Displays > Detect Displays.  You should now be able to select a display mode for the monitor.  If it still doesn't work, then I'd check that everything is properly connected.  I've had problems with colours disappearing due to a faulty connection in the VGA adaptor.

  • How do I connect 2 external monitors with full HD to my MacBook Pro?

    I would like to connect up my 2 external monitors to my MacBook Pro.  But I want to have full HD resolution.  I want to have the desktop stretched so I don't want mirror displays.  What is the best way to accomplish this?  Is there an adapter that I should use?

    Thanks for the reply. Haven't gotten anything as yet. Just that I burned out my older PowerBook using it as a primary screen w/ a secondary 20" monitor. Would be nice if the MacBooks could be used as a CPU only, connect 2 different monitors, and use the LCD screen when portability is needed. But I suppose that is why Apple makes different types of computers. I know I can rig the video SCSI cable to bypass to LCD screen and use the other built-in monitor. But there goes the warentee and any kind of AppleCare... not that I have ever used it, (until a day after it has expired!)
    But thanks for the feedback. Your reply is what I expected. Being that I am a mercenary graphic designer and need to be able to work whenever, and where-ever I need to, the MacPro is not my hardware of choice. As well, I don't have $4000 in my budget. But man do those machines rock! Just think of what NASA could have done with one of those in 1969 when we were going to the moon! But now that the U.S. has decided that manned space travel and even scientific space exploration is not worthy of having a budget, the MacPros are religated to creating new episodes of Jersey Shores!
    Thanks again for your feedback!

  • Trouble connecting 3rd party monitor to MacBook..."OSD Locked" message?

    I am trying to connect my LG monitor to my MacBook air. This monitor worked w/the last MacBook I had (2008 model) and yes, I am using the right cable. The background on the monitor is the same as my MacBook (starry galaxy image) however there are no files. When i tap any button on the monitor (e.g., menu, engine, source, auto/set) I get the message "OSD Locked". I have a feeling this is a setting from my MacBook. Any ideas?

    Hey wrtrgrl,
    Thanks for the question. It sounds like everything is up and running, your preferences may just be set to Extend your Desktop (as opposed to mirroring). Try configuring your preferences to mirror:

  • [HELP] Erratic Trackpad When Connected To External Monitor

    Hi guys, you've all managed to help me in the past so lets hope this time goes as smoothly
    So today I purchased a Sharp LC-37XD1E as an external monitor for watching movies and playing games through my MacBook Pro, sadly although everything seems to be connecting nicely i'm having some major bugs with my trackpad and wired mouse.
    For some reason when I try to move the cursor it fights against the moment almost as if it was on an elastic band, if I keep trying to move it then it start opening launch pad and switching to my other desktops, so far i've managed to find a small fix and that is if it starts bugging out and I press Esc it seems to resolve the problem for around 40 seconds before happening again.
    The Mac is connected to the monitor through the mini DisplayPort on the Mac using a VGA cable connected to a miniDVI to VGA connector.
    I know the monitor is an old model but so is my Mac and it's all I have to work with, here are the specs to help with your analysis of the possible issue.
    Macbook Pro Unibody 15" Mid 2009
    OSX: 10.9.5
    Ram: 4GB
    HDD: 500GB

    Folks: *there may be a power/signal issue going on here.* I had a similar problem of my network connection dragging to practically nothing when hooking up my LaCie external drive to the USB port. Please see my post below (link and text)
    http://discussions.apple.com/thread.jspa?messageID=9914924#9914924
    Folks:
    Apple needs to get on this issue fast; after turning off my N mode on my WRT160N Linksys Router, I got my packet speed back up to where it should be... HOWEVER I noticed another problem.
    When I hooked up my LaCie external drive (connected via USB), my packets on PING practically stall to nothing. I then eject the external USB drive and re-ping and I get acceptable packet speeds; I re-connect the LaCie external drive to the USB port and my PING crawls to nothing.
    There is CLEARLY a correlation between the network speed crawling to nothing while hooking up an external drive; possibly a power sink and/or signal interference on the Airport when hooking up a USB device? (or perhaps even Firewire 800 too?)
    I sure hope Apple is reading this one, because this could be a MAJOR issue that needs to be fixed ASAP.

  • Connecting 3rd Party Monitor to iMac 2.8 Intel Core i7 27"

    Hi Hope somone maybe able to answer this question?
    I would like to connect my Dell monitor to my iMac as a 2nd screen, it has VGA, HDMI, & DVI ports. What would be the best way, can I simply purchase a mini-display port > DVI or VGA adapter or would I require a Dual Link Adapter?
    Thanks in advance
    Mike

    A mini display port cable to either HDMI, VGA or DVI would be fine. The best way to to purchase is to buy it directly from Apple that way you know you are getting a high quality cable that has been well tested.
    BTW, your manual says:
    One or two Thunderbolt ports (high-speed data, video, and audio)
    Connect Thunderbolt-compatible devices for high-speed data transfer, or connectan external display that uses Mini DisplayPort. You can purchase adapters to connectdisplays that use DVI, HDMI, or VGA. The 21.5-inch iMac has one Thunderbolt portand 27-inch iMacs have two.
