• Pavilion 15ab165us computer laptop 15.6: How can I add an external monitor to my laptop HP Pavilion

  I have a Pavilion laptop and want to use an external monitor at home rather than on the laptop monitor.  Is it possible and I can connect it to the USB port on the laptop?

  Hey1950, welcome to the forum.

  Yes, you can use a USB port.  Here is a USB video adapter that should do what you need.  These adapters are designed for USB 2.0. but they make USB 3.0, also.  You can speak with a representative at StarTech to answer your questions about them.

• External monitor connected to the Dynadock does not work

  I just bought a docking station universal toshiba dynadock via amazon.com (latest version). I plugged on an Acer Aspire 5738zg computer laptop, Windows 7, 64 bit.
  Everything works great - except for my external monitor (6 months old packard bell viseo 190w, 18.5 inches, max resolution 1366 x 768 at 60 Hz)

  The dynadock manual says connect with monitor dynadock station via a vga cable - what I've done. Job monitor is completely black. The manual says then click the icon in the field of system status / tray (do not know what the word - the small icons at the bottom of the screen on the right screenfor side which) to configure the dynadock to be extended or mirror mode.

  Problem is that the icon does not exist. I have the icon for the audio part of the dynadock and icon for the system whole dynadock (icon called "toshiba dynadock tool" - here I can release the docking for example, but do not do anything on video/screen).

  I checked and the video/screen the dynadock element was installed togheter with everything - the installation was complete and successful. Still no icon if...
  I'm not watching videos or games, just be able to use my external when monitor I surfing online and you use microsoft word etc. - no data transfer gigantic so far as I can tell.

  How to solve this? Via the control panel of my laptop? How...? :-)

  I'd appreciate some advice that I am completely lost as to how to solve this problem (tips preference in the form of a very easy step by step 'manual' as I'm absolutely not an expert in computer science, just a regular user).

  Hi nanna.

  I think that the best way to solve this problem is to download and install the latest graphics driver for the dynadock.
  So please, use this link, download and install the driver.
  http://www.DisplayLink.com/support/downloads.php

  If the external display doesn´t not working after installing the driver, please do a right mouse click on desktop and verify the "screen resolution".
  You should see 2 screens.
  If this is not the case - there is an error during the installation of the utility dynadock.

  In this case, please visit the toshiba page
  http://EU.computers.Toshiba-Europe.com/innovation/download_drivers_bios.jsp and download the latest dynadock utility.

  Please chosse: Options - connectivity - Docks & replicators - Dynadock

  You will find the version 2.4.0.13

  hope this will help you!

  Best regards

• Portege M200 with external monitor - what is the best resolution?

  As a result of a recent post on using an external monitor with the M400, I have a question on the use of one with the M200. I realize that the M200 uses the graphics card Nvidia rather than the graphics card Intel in the M400 - is it better with regard to the use of an external display is concerned? The M200 manual says that it will support up to 1600 x 1536 resolution on an external display. I want to use my M200 in a docking station with an external monitor to the extended desktop.

  What would be the best resolution to go with externally? Should I go for 1400 x 1050 screen LCD M200 match? Or could I go for a 1600 x 1200, that should the graphics card (!) be able to cope? Or, finally, if I went to a widescreen 1680 x 1050, how would the face Nvidia card? The screen is not as clear as with the 1600 x 1050 screen?

  What are the chances of work at all? I see in the M400 manual which she is supposed to support 2048 x 1536 on an external monitor, but this seems to be a problem, judging from the other post.

  Any help appreciated - thanks

  Hello

  Well, the resolution of the screen depends primarily on the graphics card.
  If you want to use a display resolution that the graphics card must support. In addition, the graphics card driver is important. If the graphics card will support the resolution of the screen, BUT the resolution is not listed in the graphics driver, so you will not be able to choose this value.

  To my knowledge, if you use the docking station you will get Supportepar as the notebook display resolutions.
  The resolution of the external display also depends on the external display. If the material of the monitor will not support the resolution so you will not be able to get all the images on the external monitor.

  I think the best way is to test that the resolution is the best. Some people prefer the high resolution of small icons and other blind ;) like low resolutions (1024 x 768) because of the large icons

• How to set 1280 x 800 on external monitor connected to the Tecra M2V by APR3?

  Hello

  I have a Tecra M2v (with intel Extreme Graphics 2) and recently got an Advanced Port Replicator III and a 15.4 "WXGA LCD display. According to the specifications of the laptop (LINK to DL the PDF specsheet) it will support an external monitor with a resolution of 1280 x 800, but I don't know how to operate. The only resolutions that I can find are for 1024 x 768 or 1280 x 1024.

  I installed the latest version of the bios (v 1.30) and have tried different drivers of intel and can not get the wide screen resolutions to appear. Does anyone have any ideas on how I can get this to work?

  Hello Randy

  Are you sure that your external LCD can manage with a resolution of 1280 x 800? You attempted to set this resolution without Advanced Port Replicator III?

• How do I know if my laptop can run an external monitor as well as it's own screen

  I try to run a presentation with powerpoint and want to know how to connect an external monitor. my laptop equipped with a port for it, but do not seem to recognize a screen when I try

  Almost all laptops have this ability.  As a general rule, you must press the Fn key and one of the F keys to switch between the display of the computer laptop (1) use, (2) use the external screen, (3) use both.  See the User Guide for your laptop for more details.

  In addition to telling the hardware of the laptop to send a signal to the screen external, you can probably configure which displayed on the external monitor (a copy of the laptop screen) or an extension of it by right clicking on an empty area of the desktop, select properties and then click the settings tab.

  Finally, some applications (such as Powerpoint) have their own internal settings.  This is for Powerpoint 2003--> http://office.microsoft.com/en-us/powerpoint-help/presenter-view-tools-for-running-a-powerpoint-presentation-HA001056547.aspx

• Pavilion G6 2210us + Windows 7/64: impossible to adjust the screen backlight intensity

  I replaced unacceptable Windows 8 on Pavilion G6 computer 2210uS laptop with Windows 7 (64-bit). PROBLEM - I can not adjust the intensity of the backlight display (Fn keys assigned to the change of backlight do not work, they worked in Windows 8). The screen backlight is still full intensity. HP Driver web page does not include some drivers and applications for this laptop, however, I was able to locate the missing drivers on the web sites of chipset of the seller, so the Device Manager shows all devices running and the machine works otherwise OK. What additional pilot program is necessary to enable the keyboard command change the intensity of the backlight screen? Thank you.

  No, it is not normal.

  You tell me that you didn't have the video driver installed correctly.

  Perhaps this is indeed the issue.

  Try the HP Windows 7 driver for your video card and see if it works better.

• Pavilion dv7-6163us windows 7 64-bit, the screen brightness will not adjust

  I reinstalled the latest graphics driver, the latest version of the BIOS and I still cannot adjust the brightness of the screens (screen).

  The indicator appears but is grey.

  Thanks for any help, Paul

  Update on the screen brightness controls; went into the BIOS and reset on off action keys.

  Restarted and there was no change.

  I then uninstalled the drivers for the monitor and rebooted and the brightness setting now works again.

  Thank you all, Todd especially for assistance.
