Monochrome external VGA monitor

I had a monitor configuration 2 x 27 "since I got my laptop about a year ago. A monitor is connected via Displayport, it via VGA. I leave the lid of my W520 closed so I use the two external monitors. Today, I've had my laptop dropped out of my workstation and now when I try to hook it up once again the screen is connected via VGA appears black and white.

Here is what I have all my my laptop got since the monitors:

1) has had to work as usual (he has no fall or something like that so I don't think it would have been physically damaged)

(2) installed a new battery (just arrived today, original Lenovo)

Here's what I tried to get the problem resolved:

1) update both integrated and Quadro 1000 M drivers

(2) switch monitors (one connected via VGA is B & W)

(3) switched to a new VGA cable

(4) restarted my PC several times

(5) tinkered around with the settings under "Screen Resolution".

(6) checked VGA port - aesthetically it looks like there still (no damage or something like that)

Switched 7) back to the old battery and tried again

Please help me! I wouldn't take my computer to a specialist of the material because I am just out of warranty and I can't really afford a professional maintenance. Since I'm sure that nothing has been damaged physically, what other software fixes I could try?

Thanks in advance!

Check driver under color settings in the NVIDIA Control Panel. He could have saturation set to zero.

  • How to connect a macbook pro retina to an external VGA monitor

    I have a MacBook Pro of the retina on OS X El Capitan 10.11.3 running. Previously, I could connect a previous MacBook Pro (late 2009) to an external VGA monitor. I was told on the Apple store I could use the mini display in a Flash port dongle to connect to a VGA cable, but when I tried this, the monitor could not get a signal. Is there another dongle I should use? I have a HDMI cable which I assume will work with most modern projectors, but I really want to go to this old VGA monitor for editing in iMovie.

  • Satellite Pro U200 - external VGA monitor shows no output

    I bought this unit, such as used on ebay. It works fine except that the external VGA connection does not work. I'm on win 7 and I it does not recognize the external display properly and I can set it up as an expanded view. However the external display shows nothing. The external VGA display is fine because it works with other machines to laptop. I tried to use UBUNTU Live CD on this machine and tried to do the work of the external screen (and it also can recongize the external display and configure it) but there is no picture. I also connected the screen external vga port and then rebooted the machine, but still no picture. I tried to change the settings in the bios for both display, but all my actions point to a hardware failure.

    I don't know if it's a manufacturing defect? Do you know if this problem has been reported earlier for you. Y at - it a recall issued for this?
    Please advise I need to connect this external screen but am sure it's a fault of equipment with your device.

    Hey Buddy,

    Have you tried it with the factory settings? I mean the Windows preinstalled from Toshiba with all drivers and tools. If you have the Toshiba Recovery disk you boot from that disk and install Windows with all the drivers and tools.

    In addition, you can switch between internal and external monitor by using the FN + F5 key combination. It work?

    HDMI to VGA cable does not work, you need a converter to switch from digital to analog. The following is an example:

  • Satellite A100 display empty but external vga works

    Hello
    my two-year old Satellite A100-847 screen has stopped working. I used the external VGA monitor for a few days,
    and then switched back to laptop computer LCD and discovered that it doesn't work. It shows nothing, only the gray backlight.
    The LCD does not work even at start-up in WIN XP, or AC or battery power. I tried to disassemble the screen according to some guide
    to check if the cable is firmly in his place in connection to the LCD, but it has not solved the problem.
    I use the original BIOS and the somewhat updated nvidia display driver, it worked fine until now, so I suggest this isn't a driver/bios problem.
    (but maybe that is it, so I tried to install the original display with no effect driver.) I don't want to try to Flash the new bios and meet up with Kiss to the top view and bios too)
    Video output for external monitor is quite well, start-up or in the victory.

    Everyone sees a solution, please? Or should I just go to the service provider...
    Thank you
    Pepe

    I think that it s a hardware problem of the display or the FL-inverter.
    The FL inverter is part hidden somewhere close to the screen.
    It controls the backlight of the display.

    So you should go to an ASP, they can order the parts and exchange it or looking to ebay for a complete display and Exchange yourself.

  • Satellite P50-B-103 - to connect my HDMI output on a VGA monitor

    Hi all

    I just bought a satellite * P50-B-103 *, which has a HDMI output and I want to connect it to an external VGA monitor.

    I thought that I just need to buy a HDMI - VGA Converter, but the buyer was told that Toshiba, unless this model, is not ready to connect to a VGA monitor, although I use a converter.

    Is it true or I can connect my laptop to the vga monitor using the converter?

    Thanks in advance,

    Charly

    It remains that HDMI provides digital signal and analog support port VGA (RGB) signal.

    To be honest, I read a lot of articles on these adapters and converters, but in many cases, these converters are useless.

    So it s no matter if your laptop was manufactured by Toshiba or another manufacturer.
    ITSA the question of the standard of caught signals supported by each port.

    Someone else has had this problem where to connect an external monitor/projector to the external VGA port its does not work, just showing what looks like a very distorted picture, moving around the screen.
    Tried new drivers, BIOS update, change VGA settings in the bios for LCD & RGB but with no joy, does not not in Windows or in the boot.

    Is there something I am missing here or is the port on the laptop really defective?

    See you soon

  • Connect two VGA monitors to HP p6774y

    I have two old HP screen flat monitors with connections VGA I'm trying to connect to my new HP p6774y.  The office has only a single blue VGA connection in the back. I hooked a monitior to the VGA port and it works very well.  How can I connect the other?

    Unfortunately, you won't be able to connect your second vga monitor to the pc. The second video port on this motherboard is a DVI - D port. DVI - D provides only a digital signal which does not work with your analog VGA monitor.

    DVI - I to VGA adapters are available because DVI - I includes an analog signal, but also a digital signal.

    Apparently, DVI - D to VGA converters are available, but I'm not sure how that they work.

    If you want a second vga monitor on your pc, you will need to install a second vga graphics card, if you have an available housing.

    Some information about dvi connections are available here.

  • Connect the second VGA monitor to Pavilion HPE

    Hello

    I have a Pavilion HPE h8-1114 PC, that has a DVI and HDMI monitor port. I have a VGA monitor connected to the DVI port with an adapter. I have a second VGA monitor, I want to connect, but I understand that it cannot be connected to the HDMI port. Are there other options besides buying a HDMI monitor? Can I use one of the covered ports which I think is VGA? (I guess not.) Can I add a second graphics card with a VGA port and use both screens? (I saw on another post that adding another graphics card could disable the existing card). Can I opt for a card that supports two VGA or DVI ports?

    Thank you!

    In addition what erico said, there are other options. You can use a video-to-USB adapter of EVGA UV plus + 19 or you can add a x 1 PCIe graphics card. If with a PCIe x 1, using a card Nvidia... results will be the best in this way.

  • Help! What other option I have other then using thunderbolt connection to connect the VGA monitor?

    Hello

    I really hope someone is able to help and give me cheaper workaround here. I am currently using the single port thunderbolt that I have on my Mac mini to connect my VGA monitor (with mini display port to VGA). However, I would use an audio interface of stroke of lightning and therefore need to try to free this port so you can connect it.  What are my options here (other then buying a new monitor?) are there adapters that I might be able to use?

    Any help you can offer would be greatly appreciated.

  • User interface of smart camera on VGA monitor?

    For smart cameras that have a VGA output (NI 177 x), is it possible to get the UI custom embedded in the Vision allows AI 2011, to display on the monitor (VGA) output?

    Or are you limited by being only able to display the inspection on the VGA monitor image screen?

    Unfortunately, this is not possible. Technical, for those interested, it is because that the public Service. Get the Image method only is not supported on RT.

    The custom user Interface is designed to interact with Vision Builder running on the target. It will appear in the mode of inspection on the Vision Builder running on the host machine or on a web browser if you enable the web server on the target and connect from a web browser from another machine.

    This application note gives more details: http://zone.ni.com/devzone/cda/tut/p/id/6714

    There is a way to achieve a similar result, that is to draw overlays in the image using the Custom Overlay stage located in the palette to use additional tools.

  • Troubleshoot the switch 12 with a projector or VGA monitor Acer

    I connected my Acer Aspire switch 12 to a VGA monitor via a HDMI VGA adapter microphone. The switch 12 sees the second monitor, but seems unable to get a signal to start it. In this respect also disables my wireless and sometimes the mouse as well. I tried the VGA monitor with my MacBook and it works perfectly.

    For me, it's a serious problem, I bought the switch to travel and give presentations in corporate meeting rooms, of which many are still equipped with legacy VGA projectors.

    As a low-power machine, is inherently impossible to connect to a monitor/projector VGA switch 12, or is the problem somewhere else?

    If I had to guess, I would say that the problem lies in the switching on of the conversion your HDMI cable VGA chip. I do not know the specs on the budget for food for the HDMI port, but it is probably marginal for the conduct of the conversion.

  • Acer XC-605 does not work with VGA monitor

    I just bought it, SNID is *. I may have made a mistake, as I bought it without a new screen, thinking the old man I would have worked.

    My monitor is an HP w2007v with a VGA port. There is a VGA port on the back of the Acer tour, I thought that there should not be a problem, but there are. My monitor says that he receives no signal from the computer. What I need to get a new HDMI monitor, or she would work with an adapter HDMI / VGA?

    If I have to buy a new monitor, which is better to connect it to the computer? The installation sheet short I said can I use DVI, VGA or HDMI, all the same, but this is not the case. I would say there was a small cap on the the computer's VGA port, but it was not written on the box that I couldn't use it. I thought it was a protection for the transport. So, why is there a VGA port if I can't use it?

    [private under the leadership of life]

    So, I don't know a lot about the HP monitor, but I hope I can help to explain what you're looking at.

    I have attached a picture of the back of an AXC-605, there may be slight differences, but overall, it should look familiar.

    Let me start by explaining what is the VGA port on this system. Almost every Office mainboard has a VGA port available. This is because the video is a requirement for the P.O.S.T. process. The reason why it is not used is because the unit has a dedicated video card which is more powerful and the system is configured to use this dedicated card and not to provoke a conflict with the built-in VGA port. Is it possible to use the VGA port? Probably, but you lose a lot of performance with the sytem.

    The image options are highlight in slot 13, HDMI and DVI. The best way to connect a VGA monitor would be with DVI to VGA connector. Those who are about $ 3-5 in the States.

    Hope this helps,

  • Aspire V3 - 771G recovery loop/Broken Screen / external VGA screen

    The problem is 2 things:

    2: now, we cannot access BIOS because of the external display is VGA but if we close the lid, we'll see, only the "Recovery" loop... »

    My friend used his laptop with and the external HDMI display for a while.

    then he noticed he has more behaviors in addition to viruses, like: acting as his pirate.

    a person resumes his mouse and so on.

    So he decided to make his pc recovery and then we can operate in Mode external VGA,

    but not HDMI and more.

    Reason for no longer works in HDMI is because of Windows may have these drivers?

    (external mouse and a keyboard installed)

    Try to start the computer on F10 or fn + F10 or F2, (laptop keyboard) and then close the cover.

    Even on the external keyboard.

    In any case suggestion as to access the BIOS with an external VGA display.

    Or any other suggestions?
