Portege Z830: I want to disable internal LCD and use only the external monitor

I have a Toshiba Portege z830.
I use my laptop in "Extended desktop", mode with an external monitor, which is the main display.
In this mode, the two screens are still on, but I want the built-in LCD screen to be opened only when I use it.

Is this possible?
Thank you.

Hello

In my opinion, this is not possible.
In extended mode, you use and display internal but extended and the long part is visible on the external monitor.
In such a case its any that your external monitor is set as main display.

If you want to use an external monitor only, you can only export the video signal on external monitor by pressing FN + F5

  • I want to use only the external mike and headphones

    However, somehow the microphone for the internal webcam or Skype or else suddenly transformed, so now I have two of them.  The internal MIC is echoing to the sounds of television, me and interferes with my external mike recording.

    I cut it by adjusting the levels, but I want that he TAKES... OFF!  When I go into properties, it shows just an icon for the external mike and headphones, it does not seem to suggest that there is another work of mike.  It's windows 7, 7 year old computer.

    Any ideas?

  • Satellite P200 - LCD is black but the external monitor is OK

    Hello

    I have a Toshiba P200 17.1 ", LCD has gone black,
    You can see the backlight in the background.
    It turns on sometimes.

    I checked with an ohmmeter lead LCD and it seems to be ok, is not sure that that is the problem.
    When I connect it to an external it follow the work ok, made his first appearance on the backlight.

    I suspect it is the LCD screen, but I would check with certainty before I part with my hard earned money.

    Question, I have a spare screen Latitude D600 14.1 ", with the same connector on the LCD (30pin)
    Could I use with inverter P200 to see if there is a signal / MoBo to the power connector.

    Thank you

    Spike

    Hello

    You must use the display 17.1.
    Your Latitude D600 screen is 14.1 "so it will not work.

  • Internal untrusted clients directed to the external IP address for traffic PCoIP

    I have a network segment disable my firewall for some untrusted clients. When untrusted clients connect to view (5.3), they use a DNS name that resolves to a DMZ (view Security Server) host. That's where I think the problem is: it seems that security server responds with its external IP address, and then all the PCoIP traffic is routed to my router (where the external IP address can be found), then back into view and the customer. Traffic of SSL connection works fine, the traffic remains inside and does not get directed to the external IP address. It is only the PCoIP traffic that gets invited to use the external IP address.

    It seems that DNS is not enough - Security Server seems to respond and connect using only the external IP address configured in the external URL field PCoIP - is this correct? If so, then to do a substitution for the external URL so that internal untrusted traffic doesn't get routed the external IP address - this creates a lot of unnecessary traffic, mess with QoS, etc..

    Another idea would be to allow untrusted clients to connect directly to a login server instead of sending them on the Security Server, but I don't think that it is a best practice...?

    Mike

    As Linjo says the simplest solution is to set up a server for additional security to point these clients (no need of another server connection, you can pair it with the existing one). Today, you are required to provide an IP address for PSG, so if you need to send it to another, you will need a second server.

    Of course, if they are completely not reliable customers, then you can force through the external access point still but looks like you need avoid the cost of additional traffic from this approach.

  • Portege R600 - how to use the external monitor on the docking automatically

    Hi - I just got a new Portege; R600-102. It's a great machine - very light and fast.

    I connect to a Slim port replicator to the office and I wish I could anchor and automatically use the external monitor without opening the laptop. Can someone point me in the right direction on how to do it? This process has worked well on my recently retired Dell X 300.

    More precisely:
    # I have the laptop closed Portégé and standby mode
    # I anchor in the Slim Port Replicator (SPR)
    # I press the button 'on' on the SPR
    # I see the message "recovery windows" and the bars of the countdown on the external monitor. (So I know it's connected and you can see the external monitor)
    # The laptop turns on but use the laptop screen (private) LCD
    # I have to open it and manually tell it 'out to watch.
    What can be automatically?

    Thanks for the tips.

    So I have to change the default to Google Maps then back to Google to search for one.

    I have it! It's the topic: config "hiddenoneoffs" where the 3 elements of google, maps and mcafee have been included. There was no space between Google and maps. I put one in from Google Maps. She appeared in the first box-ff, but not sure about the search in the second time zone. I went back to the subject: one-offs. Safe search was shown with a space after Secure. I took out the space. Safe search arose in the 2nd single search box!
    Weird! This is contrary to how they show in the search parameters.

    Hello

    How have you tried to exit from display on an external monitor?
    Usually, you use the FN + F5 key combination.
    This allows you to switch between the two screens; laptop + external display.

    I had a problem to view a video on the external monitor because the video is already running. You must switch to the external display until you start the movie, etc.

  • The Parental account for my child's account has been disabled for inactivity and to accept the new terms of use for the xbox update must be parental confirmation.

    The Parental account for my child's account has been disabled for inactivity and to accept the new terms of use for the xbox update must be parental confirmation. I can't do this because even when you type the parental email address in the password recovery, it does not recognize because because it is inactive. I need a Windows Live technician to reactivate the account and I don't know if I should put the email address of the account here for security reasons. My other question is also if you can't reactivate can you switch parental permissions to another account.

    In the right side window, click on the NoAutoTrayNotify value and select Edit. If there is a '1', replace it with "0".

  • Disable the external monitoring?

    Hello

    Is it possible to disable the external monitoring a link by link or by email by email? I ran into a few sites that we need to link to who do not co-operate with the added query string parameters, some who disagree so they throw an error page that lists settings such as unknown instead of display content we target our audience to see.

    The only way to disable what I found is through unchecking configuration > e-mail setup > [_] follow-up external - but who is an account on the scale parameter, and this is necessary on a case-by-case basis.

    Thank you

    Richard

    I don't believe it.  You might be able to create a redirect link to change the settings of final query sort string...
