Connect external monitor via the VGA port > > BSOD

Hi all

I have a laptop Acer Aspire V3-772 and I had an (obvious) problem. When I connect an externel to my VGA port my laptop freezes. After that I restarted my laptop (still connected to the monitor via the VGA input) I get the following BSOD:

video_tdr_failure igdkmd64.sys

This error I've read on the internet has nothing to do with the video card intel. On this laptop, there intel 4600 internal videocard. There is also a second video card which is geforce gtx 760 m.

I updated my system completely and everything works fine. Except the VGA port.

I tested my HDMI port that works correctly, open the same screen/monitor connected via the VGA input it freezes / BSOD.

One give me advice on what could be the cause?

is this hardware or software really? I think that the software. In any case I'll try to install the older version of the video card driver intel. I'll post if it works.

I would like to have some advice on this issue.

Thank you!

Thanks for your reply. I tried already. HDMI works very well but even VGA displayport monitor (so double male vga cable) causes system hang still > BSOD.

I did a factory reset. Same result.

Conclusion... Its a hardware problem.
I'll contact support so they can pick up my laptop for repair.
I lost my weekend for this problem.

I'll change this topic as resolved since it's associated mobo (intel grappics card).

  • Satellite P750 - unable to connect an external display via the VGA port

    Hi all

    My problem is the following:

    I tried to connect my P750 (running on W7 x-64) an external display using the VGA cable port. Unfortunately, these devices recognize my phone. Laptop does not recognize the external display, you can see in the graphics settings as additional display, but the screen shows "no signal".

    The computer always identifies the screen correctly, so it seems that there is communication from the screen to the PC, but not the reverse.

    This has been verified with 3 separate screens and television - still the same. All the screens work properly with the other PC.

    I already have:

    -try to play with FN + F5 / "windows" + buttons P - no change
    -install the latest drivers BIOS and video site Web from Toshiba - no change

    Suggestions how to operate? Is it possible that the VGA port is faulty?

    Thank you in advance.

    Hello

    You have the same problems with a HDMI output port?
    Usually, you don't need to change anything to get the external monitor works.
    Press Fn + F5 several times until the monitor RGB (VGA) was selected
    Since you can choose an HDMI output too, you should pay attention to this option.

    Have you tried to change the resolution before using the Fn + F5?
    It s worth a try

    Last but not least, you could set the default BIOS (press F9 BIOS and save the changes by pressing F10). But I don't very well if the BIOS contains some parameters of port RGB (VGA) m

  • Unable to connect 2 external monitors via the Port Replicator using Portege Z30 - 16U

    Hi all

    I need hell, I just moved from another laptop for Portege Z30 - 16U, I spent hours trying to connect my 2 external monitors to my Replicator Port Hi-Speed III 120W, but my laptop will see a monitor.

    I used 2 external monitors with my laptop for years because I do a lot or reading and I don't want to use the one and the laptop screen.

    I tried the mixture of a VGA and a HDMI and VGA cables, but nothing works.

    Can anyone tell me how I can connect and discover 2 external monitors with this laptop and port replicator, I can't believe that this is not possible, it makes no sense that Toshiba would then technilogically behind other laptop manufacturers.

    Thank you

    Liga

    Hello

    I'm not familiar with the Z30 Portreplicator, but the general behavior of the replicators of the double-displayconnector, is that 1 can be used.
    Not 2 simultaneously.

    I could be wrong, and you should easily be able to check it out - use only 1 at a time.
    First, then the other.
    If the two works when used alone, then my suspicion is right.

    I hope this helps!

  • Satellite P100: Can I connect two external monitor to the VGA & DVI port at the same time?

    Satellite P100 comes with two port external monitor. One VGA and one DVI. Can you have two external monitor works at the same time? Can you have two external monitor as well as your internal screen working at the same time (for a total of 3 screen at the same time?

    Here's what I confirm:

    Internal display + display DVI connector
    OR
    Internal display + screen VGA connector

    Is it possible to have:

    Display connector DVI + VGA connector display?

    OR

    Display connector DVI + VGA connector screen + internal display?

    As far as I know, this is not possible and you can use a DVI or VGA port.
    Output signal can be used only a single port for external monitor.

  • Tecra 9100: Unable to connect external monitor to the APR III Plus via DVI

    Hello
    I have a laptop Tecra 9100 that I try to use with an Advanced Port Replicator III (APR3 +) to connect to an LCD flat screen widescreen Dell via the DVI connector, but so far without success.

    All other connections on the APR3 + operate without problem, the monitor stir however not until Windows finishes loading, how it shows a totally white screen with black bars very close down vertically.
    I upgraded to the latest version of the BIOS and tested all the cables, but in vain. I also carefully searched from Toshiba Web site, but the only document which deals with taken ports supported on the APR3 + I can find does not list my laptop model at all.

    Please can you tell me if this mode of operation is supported and if it is how to enable it?
    Alternatively, if it is not supported, could I use a VGA - DVI cable to connect the APR3 + LCD flat screen?

    Concerning
    Ross.

  • U2413, calibration solution Ultrasharp fails to connect to display via the USB port

    Dell U2413 SN: CN-0YCM0F-72872-48P-A81L REV A01 August 2014

    Try to run the ultrasharp Dell V1.5.3 on this monitor calibration solution, however, the software stops and displays "please connect the screen to your computer via a USB cable." I click the OK button after you have checked that the USB port on the computer is connected to the USB connection screen, but ultimately, this message appears:
    "Could not establish a connection to the screen. Please make sure that the USB cable is connected and try again. »

    Has tried this on two different computers, running Windows Pro 8.1. One was connected to the monitor cable HDMI to DVI (Thinkpad 10 via docking station), the other using the provided Dell Display Port printer for (Tablet Thinkpad X 230) mini display port cable.

    The USB ports on computers were connected the Dell supplied USB 3 cable to the monitor. Also tried this on a single computer by using a USB 2 port and a USB cable with the same result. The USB connections on the monitor seems to work ok when you plug a flash drive or the i1 Display Pro. Also, did a reset Monitor USB and verified that Windows has seen additional generic hubs when the USB Monitor is connected to the computer. There are 4 additional hubs when you use additional 2 usb hubs and USB 3 cable when using the USB 2 cable. In addition, power cycled the monitor several times (as recommended in the version that is known for this problem) without success.

    Before the attempt to make the calibration:
    A factory reset on the monitor.
    Ran the monitor self test and SUBMISSION. No problem found.
    Monitor purchased from Dell November 2014

    Same result with V1.5.7

    Any suggestions? Where should I go from here?

    I had success in the U2413 of profiling. I pulled out an old workhorse, a Thinkpad T43
    under Windows XP. Then installed the ultrasharp Dell V1.5.3 calibration solution and all
    updates available from Microsoft, but no other software - nothing of the Dell-supplied with
    the monitor. Used the DVI - connection DVI and USB 3 cable supplied with the monitor. The
    software Profiler has worked well with this configuration. When the program first took to the "Start
    Screen measure"(where the problem occurs already noted) Windows (message status bar)
    has reported that he accessed software Realtek 3.0. So I focused on research at the Realtek
    software on other systems.

    On the Thinkpad 10. There were two 1. "Realtek Card Reader" and 2. «Realtek USB 2.0 Card Reader» I have
    removed both and reinstalled the software Realtek for Dell monitor CD. Insert an SD card and
    a USB in the monitor and both were seen by Windows Explorer. There was also a Realtek USB
    3.0 card reader to showing in Manager devices under USB controllers. Using the connections between the T10 to monitor previously described the Profiler software, then ran normally.

    X 230 - I removed the "Realtek Card Reader" (V6.2.9600.30168) software and tried to start the
    Software Profiler and it does not at the same point as before. Then I installed the Realtek USB 2.0
    Software for the Dell card reader. However, there was still no Realtek USB 3.0 card reader
    display in the Manager of devices under USB controllers. Software Profiler is not like before. I then
    inserted an SD card in the monitor and the "Realtek USB Card Reader 3.0" appeared in the device
    Manager. Software Profiler, then ran normally.

    So now my two systems Windows 8.1 software profiling will not work if the 'Realtek USB 3.0 Card '.
    Reader"is not listed in Device Manager. To do this the software must be installed (for example
    starting from the Dell CD) AND an SD card must be inserted into the SD slot on the monitor. Remove the SD card
    Card and the device disappears and profiling software will not run. Insert an SD card and the
    Software Profiler works normally.

    How can I get the "Realtek USB 3.0 card reader ' to automatically load before running the Profiler software?

  • Communicate with external devices via the USB port on the Playbook

    Hi all

    I've been looking for more information on how to connect to external devices programmatically using the port USB of the Playbook. It seems that the QNX Neutrino system level options do not work, I tried to use system() with some usb since utilities commands (e/s-usb, usb,...) without success. I'm trying to build an application that uses the USB port of the Playbook to connect to a network industry such as devicenet or profi-bus as an example. Anyone know if this is possible? If this is related to another post here, admin please move.

    Change Note: Please answer and the result is pretty much that I had found. I have no contact I can name for RIM, off the top of my head. I think for now, I'll concentrate my efforts for the development of the Playbook.

    This is my speculation, but given the current philosophy of the PlayBook and BB 10 OS, perhaps my speculation is not too bad. Anyway, it is not only a problem of BB, other editors (Apple, Samsung, LG etc) also do not allow this out of the box.

    A few days ago, I played with ultra cheap Chinese junk-Tablet (with resistive screen, buuuu), android 2.3.3 and this unit has a usb port with support for any device usb (mouse, keyboard, 3 g modem) + adapter Ethernet usb custom with 2port usb hub. Man, it was crazy. Maybe these will find its way in BB 10 devices a day.

  • 2.72 TB external drive via the USB port

    I realize, this is an old post, but I really need help.  I formatted a 3 TB on Windows 7 64 bit external drive connected via USB. I must have formatted MBR but player showed still 2.72 TB of space - great! I copied the backup data on this disc, leaving 129 GB of space.  The problem seems is occurred when I actually copied data that was full of 2 TB.

    After that everything was copied, I went to remove disc and it says that it is in use. I waited for an hour, the same thing, so I restarted the computer. NOW, this drive will rise not on any computer, almost as if he needs formatting / initialized as a raw player! Please help as I have more data anywhere, but on this disc... certainly there must be a way to read data from this drive?  Is there a system I can try to retrieve data?

    I'm on Dell T5500, BIOS = A09.  Most recent update of the BIOS and update Intel RST?

    Thank you!

    Hello

    Go back to your original information you posted, the hard disk had be GPT formatted and not MBR otherwise the hard drive wouldn't format on 2.72 TB.  How can he be a former post office at your first post about it is dated today?

    Removing a hard drive which is currently in use is never a good idea that he could make the hard drive completely unusable depending on what operation is made at the point where the hard drive is removed.

  • Try to use the capabilities of the Web from TOSHIBA camera with an external device via the USB port.

    Toshiba Web Camera software that came with my new Qosmio X 505 - Q880 is very useful, and I would use it to take pictures with an external camera connected by a USB cable (camera is a Kodak DC290, in case this is useful).  Is it possible to use the webcam with anything other than Toshiba built in webcam?  Now that I'm typing this, it seems a question more appropriate for the Toshiba site, but I guess I'll try here first.

    Toshiba Software is for Toshiba hardware.

    I bought a VGA S-video/audio adapter and connected my VGA port and the TV.

  • Bad resolution of Qosmio G30 - external display via the HDMI connection-

    Hello! This problem makes me crazy, please help if you can...

    I just bought a G30-102 and I am trying to use it with an external display via the HDMI connection. The problem I have is that the native resolution of 1920 x 1200 cut the edges of the screen and the quality looks terrible - its almost as if the entire screen is enlarged. I tried with a BenQ FP241wz initially (1080i is 1920 x 1200) and the Toshiba helpline could not find a solution either - even after painfully reinstall all the drivers, etc..

    Its been going on for so long, I thought I'd try it out with my HDTV instead, just to be sure it wasn't a monitor problem. So I tried with my Toshiba 32WLT66 - and come to find that it has exactly the same problem.

    All the display settings appear to be correct and the G30 is convinced that the result is correct, so I have now it is - don't you think not that this is a problem with my HDMI port?

    Please help, I'm a designer, and it is essential that I use the machine on a large screen. If it is a hardware of the G30 problem, I need to talk to Toshiba immediately replace or fixing.

    Hello

    I tested the Qosmio G30 (HD-DVD) with my LCD TV using a HDMI cable. Everything worked perfectly. As a first step, I put 1080i value in the settings of the BIOS and after following the instructions in the HDDVDGuide document under http://support.toshiba-tro.de/kb0/TSB6A01LH000LR01.htm

    Well, then your USB port is likely.

    Restart the PC and BlackBerry (with smart BlackBerry power onthe phone, remove the battery for a minute and then reinsert the battery to restart).

    Then, connect with the USB cable and a rear main USB port at the back of the PC, not a front USB port.

    Hear a ringing or sound from the PC indicating that the BlackBerry is connected?

    Start the BlackBerry Desktop Manager software. Give it a minute to recognize the connected BlackBerry device... you see the code PIN of BlackBerry on the PC in the BlackBerry Desktop software?
