Viewsonic VG2030wm not detected on DVI

Hello,
I got a MacBook Pro 13' and purchased at the same time a Mini DisplayPort to DVI Adapter to use with my ViewSonic VG2030wm. To my surprise, when I connected the monitor absolutely nothing happened, it goes completely undetected. The monitor works perfectly fine with a PC using an Nvidia 8600 through the DVI connector. I tried with both a single and dual link cable. I seem to be not the only one with this problem since I've found a few posts around but with no answers.
Later I exchanged the DVI adapter for a VGA one and the monitor worked fine but I would like to be able to use the DVI quality. I've asked twice at the Apple store and nobody has heard of such a problem. The monitor specs say it has a DVI-D (with HDCP) port.
Any ideas?
Thanks!
Hector

I had/have the same problem with a MacMini (with an Intel GMA 950), VG2030wm monitor and DVI cable. It worked fine with a VGA cable (but I had to use SwitchResX to pick the native 1680x1050 resolution).
I partially solved the problem (in Mac OS X 10.6) by unplugging both the MacMini and VG2030wm from the wall for 1-2 minutes (to reset the VG2030wm's settings?), and then resetting the MacMini's PRAM (by pressing and holding Command + Option + P + R while booting).
Unfortunately, I still have problems (black screen or native resolution not detected) when I restart o wake up the MacMini. The workaround I have found is to turn off the monitor (with the button on the front panel), wait a few seconds, and then turn it on again (and repeat) until the Mac Mini's picks up the monitor at 1680x1050 resolution.
I think there should be a way to force (instead of detecting) the EDID display information of the VG2030wm in Mac OS X by editing the /Library/Preferences/SystemConfiguration/com.apple.Boot.plist, but I don't know how to do it (or if it's possible at all).
Hope it helps a little.
Regards,

    You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
    That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
    Refresh & sesolution are the first things to look at.
    Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
    I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

  • Mac Mini does not detect DVI display on startup

    Okay, I have a Pre 2009 Mac Mini 2Ghz Core 2 Duo. My monitor is a Westinghouse Digital LCM-22w3. The display is hooked up through DVI. When I start or restart the mac, it seems that it does not detect the display is plugged in. I have to wait for OS X to finish booting to either put the mac to sleep and bring it out of sleep or unplug the DVI cable and plug it back in to get the display on. If I hook the display via VGA using the VGA to DVI converter there is no problem. I have tried resetting the NVRAM but that does not fix the problem. I would like to get this fixed so I don't have to switch cables to be able to boot my boot camp windows install. Any help is appreciated. Thanks!

    Following some investigations the problem appears to be with the power saving features of the monitor.
    The MAC mini knows that the monitor is connected but the monitor puts itself to sleep.
    The problem appears only when you use a single link DVI-D cable.
    These are the ones with two blocks of nine pins with one large blade.
    If you use a Dual link DVI-D cable (twenty four pins and one blade) the problem resolves itself and the display is active from power on.
    It looks like the mini or the monitor is using one of the pins from the middle block of six for some reason.
    Anyway, good look with this, I had a couple of spare DVI cables from when I was trying to get my original G4 mini working with my TV.

  • T420 - external 24" monitor DVI- Displayport : not detected when connected via KVM switch

    Hi,
    I've been using a 2port USB KVM Switch from InLine for a long time connecting a mac mini and a macbook pro
    to a 24" LCD. Recently I had to replace the MacBookPro with a T420. Unfortunately the T420 does not detect the
    monitor, when connected via the KVM switch.
    I tried:
    A) T420 -> Lenovo Displayport to DVI-Adapter -> KVM-Switch -> 24" monitor: NO SUCCESS
    B) T420 -> Thinkpad miniDock Series 3 DVI Port-> KVM Seitch -> 24" monitor : NO SUCCESS
    C) T420 ->Thinkpad miniDock Series 3 DVI Port-> 24" monitor - > SUCCESS
    D) T420 ->Thinkpad miniDock Series 3 VGA Port -> 24" monitor - > SUCCESS
    So I have a workaround, but leaving out the KVM switch is not a long term option.
    This is all on Win 7 professional / 64bit
    Using config (A) I then installed the Intel HD Graphics Driver version 8.15.10.2342 16 May 2011
    SURPRISE: during driver install, the monitor WAS detected!!!
    SECOND SURPRISE: after reboot I was back in the old situation where the monitor was NOT DETECTED
    CONCLUSION:
    Seems like a software issue with the Intel HD Graphice driver.
    ANY HINT/COMMENT/HELP highly appreciated!
    Thanks,
    Michael

    hey mgold,
    as the T420 works correctly with the external monitor and with the miniDock ; it is sad to say the the KVM switch is non-compatible.
    I would recommend that you get in contact with the manufacturer of the KVM. At the same time, try uninstalling the current video drivers of your T420 and see if it makes any difference with the KVM if the T420 is running on a generic driver

  • T410 running Windows 7 not detecting HP LP3065 connected with DisplayPort to DVI Dual-Link

    I am running Windows 7 on a Thinkpad T410.  I have an HP LP3065 monitor connected to it using an Accell DisplayPort to DVI Dual-Link adapter.  Windows 7 does not detect the monitor.  The NVIDIA drivers are up to date and I have tried powering the Accell adaptor with multiple USB ports.  I do not know if there is a problem with the adaptor or if Windows 7 is just unable to see the monitor with this combination.
    Could someone please let me know how I can diagnose this?  Thank you in advance.

  • DisplayPort to ViewSonic VG2030wm Issue

    I just received my MacBook Brick and after connecting it to my external desk monitor(ViewSonic VG2030wm) via a DVI cord with the DisplayPort DVI adapter I see nothing. Nothing happens when I click detect displays. Have restarted the computer, unplugged the monitor.
    When I tried the DVI adapter with my InFocus Projector, everything worked fine. I've used this same monitor connected to my G4 PowerBook 1 ghz via the DVI port with no problems for the last year or so.
    I found this article, but am hoping there's some other more immediate advice out there.

    So I went into my BIOS and saw that NVidia Optimus was enabled but the OS detection for Optimus was disabled. Doesn't that kind of make Optimus useless? Anyway, I enabled OS detection and now the TV seems to be working just fine.

  • Cinema Display not detected

    I got my 20" Cinema Display back from repair today (backlight problem) and now I can't get my MacBook Pro to detect that it's attached. While it was at the repair center, I used a CRT as a second monitor. So today, I just closed the MBP (didn't shut it off, which I think is what cause the problem), disconnected the CRT, connected the ACD and opened the MPB back up. Completely black screen, with the little LED on all the time.
    So, troubleshooting:
    - The MBP still detects the CRT
    - ACD is detected by both a G4 and G5
    - A different 20" ACD is ALSO not detected by my MBP
    - Reset NVRAM and SMC
    - Booted MBP in safe mode
    - Booted MBP from startup CD
    - Tried various resolutions while the CRT was connected, thinking maybe it was stuck on one that's not compatible with the ACD
    - Moved and recreated the com.apple.windowserver.* files
    I'm running 10.4.9 and here's what the graphics/displays info says, WITH the Cinema Display connected:

    UPDATE:
    I just got back from my visit to a mac genius. Of course Murphy's law was in full effect! With my MBP connected to the cinema display in the Mac store, everything worked as it is supposed to.
    Well, I rush home thinking that maybe mine would now work - - no luck! He did suggest that I try connecting analog with the provided dvi-to-vga adapter. This suggestion DID work! BUT, I want my video digital! That is why even though I was happy with the iBook G4 that I bought last year, I wanted digital video + expanded desktop!
    I think I will make another reservation with the Mac Genius, but this time, bring my monitor. Will keep you posted...

  • My imac will not detect external monitor after recent update. Is there a way to fix this?

    I have a VGA monitor plugged in to my imac using the VGA adapter to the mini-DVI.  All was working well.  Since I updated over the weekend, the computer will not detect the monitor.
    Any ideas how to fix this?

    Pcantin wrote:
    I have tried another VGA monitor and that failed as well.  Since you don't think the update was the cause, it may be that the adapter I am using decided to call it quits.  I will see if I can find another and test that out.
    I will look into the external drive idea as well.
    Thanks for your help on this.
    I didn't think about the adaptor, but you should at least visually inspect both the adaptor and the cable at both ends. If one or more pins got bent even slightly the connection might fail. The cables can also fail internally. Replacing the adaptor and cable may be the quickest thing to do initially. If you want to try to save money, first replace the adaptor, and if the problem persists, then go replace the cable (or vice versa).

    - connect only apple cinema display with mini displayport to DVI and turn on coomputer
    - connect both displays, went to System preferences -> display and click on 2Detect display"
    nothing works

  • Not Detecting Dual Monitor

    I've got a 4870 card and connected the DVI port to a 27 inch Samsung and the mini-display port via the $99 mini-display to dual link DVI adaptor to a 23 inch Samsung. This set-up worked fine with 2 of the 23 inch Samsung, but now it is only detecting the monitor connected to the DVI port. It is not detecting the monitor through the dual ink adaptor.
    I swapped around to eliminate other variables, and also tried unplugging from the DVI port and running the mini-display to dual link alone: nothing.
    The mini-display adapter is working fine with my wife's macbook pro. As mentioned, this set-up works fine with two 23 inch monitors. Any thoughts of what I might try?

    In searching, saw what Martin Pace wrote in another post on this: first, make sure the mini-display port is fully plugged in! There's a fair degree of resistance over a distance, so it's easy to think it's in and be afraid of forcing it. Of course, plugging in makes it work instantly.
    So Martin, if you reply, I'll give you a solved!

  • ViewSonic VA912b not working with new MacBook Pro i7

    Hi --
    I just received my new MBP on Wednesday, along with it I purchased the Griffin Video Display Converter (http://store.apple.com/us/product/TY600VC/A?fnode=MTY1NDA3Ng&mco=MTY4NzA5MDY) so I can use the computer with my ViewSonic VA912b 19" monitor w/ DVI at my desk, and my television w/ HDMI in the living room. I've plugged the monitor into the adapter and nothing is happening after hitting 'Detect Displays' in the Display menu. For the computer I had prior to this (2007 MBP), I had no problems hooking up this monitor and it would automatically find it. I looked through the user's guide and did some searching on the web and I'm finding nothing about this topic...does anyone have any insight into this?
    Thanks in advance!

  • External display for T520 not detected

    Hi!
    I have ThinkPad T520 and Samsung 17'' display with DVA output. I bought DVI-VGA adapter and connected the display to laptop's VGA input. The external display is not detected - it is not present in Windows 7 display properties and it shows "No connection, check signal cable" on it's screen. I don't think that there is something wrong with adapter, because it's new. How can I setup it correctly?
    Thanks!

    Hi, koles
    Thank you for the information. In the past, updating BIOS was something that was rarely done, as it could lock up and not work, which would render the computer useless if it failed. Today, however, it is not like it once was. As with updates, there is still some risk involved, but there is now a utility that will update the BIOS for you. If you'd like, you can update all the other drivers first and then do the BIOS as a last resort if you would rather not try it unless you need to.
    Hope it helps. Keep me posted!
    Best,
    Adam

  • T61 and the Intel Graphics Card error - external monitor not detected

    T61 with Vista 32 bit, Mobile Intel® GM965 Express Chipset and an Advanced Mini Dock.
    I am trying to use the DVI port and an external monitor. The driver does not detect the external monitor.
    Uninstalling the Intel driver the Generic profile will work on the external monitor, but is overly fuzzy, how do I get the T61 to recognize my external monitor with the right drivers?
    I am currently running the Intel Driver Ver. - 7.14.10.1329, which provides the message under Multiple Display:
    Two displays must be connected to the computer before you can use this feature. Please connect another display.
    Of course my 22" monitor is connected.  That is the frustrating part.  I have also uninstalled Presentation Director, just in case, but then re-installed after it seemed that wasn't the problem.
    There is a newer driver from Intel but it is not Lenovo approved yet I guess. Though I highly doubt this is the problem. What can I do?
    ~~
    I did post a thread on the thinkpads.com too, but so far haven't had any luck.

    Well the new dock came but didn't fix the problem.  Now my nice new T61 is packed up in a depot box, waiting for DHL to come pick it up.
    dkaufman1 -- I guess we do have different problems.  If I set my T61 to display to the DVI port in the bios I get a blank screens on both the DVI connectd monitor and the laptop screen until the OS boots when I have the laptop in the dock.  The only way I can see the bios screen to set it back to the ThinkPad LCD setting is to boot it disconnected from the dock.
    I really hope that this problem is resolved, as I really like the T61 otherwise.  I was even using it with the VGA cable connected to my 22" monitor, but it was pretty hard to take.   I'm now back to my old desktop hooked up to the same monitor via DVI and it is quite the relief, even if it isn't as zippy as the T61.

    My xorg.conf is here.
    My Xorg.0.log is here.

    I'm having the same problem as you. I posted another thread before finding this one. I can't seem to get any replies either.
    I don't know if we're the only ones having this issue or if no one else is trying to use S-video or what. I really wish I could get mine fixed. I tried the xf86-video-ati-git from AUR but it didn't help.
    The only difference with my problem is that xrandr also shows a DVI-0 at the bottom. I don't even have a DVI-0. I have a VGA-0 like you do. I wonder if xrandr is detecting the S-video as DVI for some reason? Though I've tried setting up DVI-0 as I would S-video but that doesn't work.
    Have you solved this by any chance? If so I'd be interested to know how. Thanks and good luck.

  • Mac Air not detecting NEC Mutlisync LCD display

    Mac Air is not detecting an additional display. Any ideas?

    same problem w/macbook air 13" with snow leop. minidisplay to dvi acer 24" external... intermittent the external won't wake up. After much research I see others have the same problem and no answers except: 1. plug/unplug dvi, 2. reset to sleep and rewake up -
    This maybe connected to the monitor not auto detecting which input is connected after wake.  from what I see it's no better w/Lion or Mt Lion
