Not able to connect the second monitor

Original title: Second monitor visible only on the first plugin

Implementation:

New (Nov 2014) Lenovo PC

AMD A8 H535

Windows 8.1

AMD Radeon HD D 7560 w / VGA output and an HDMI output

Two HP w1907 monitors (resolution is identical on both screens - when they work together)

Question:

Last night I plugged my second monitor to the HDMI output with an HDMI adapter / VGA of the Amazon ( adapter ), plug the monitor into it has not come and via the control panel (I tried both via the control panel and some change PC settings) could not detect the second monitor. Then, I went to the HP website and downloaded the drivers, but to no avail. Then I reached down and unplugged the second monitor and resettled to make sure that there is a link, this solved the problem. The monitor came and no further investigation was necessary. However, this morning I woke up the computer to a single monitor and still unable to detect the second monitor. Only when I unplugged and re-inserted the link it works.

I'm at the end of my rope and need help with this, thanks in advance for any help you can provide.

  • Not able to connect the earpiece/headset Bluetooth for Wndows 7 Enterprise (64-bit)

    I tried to connect a new Bluetooth headset to my laptop Lenovo T420.

    The laptop runs on Windows 7 Enterprise SP1 (64 bit OS).

    The laptop has built-in Bluetooth adapter and I turned on.

    Also, I went ON my helmet and guarded in discovery mode.

    After that, I added the helmet using the button 'Add a device' from the control panel-> devices and printers.

    Windows 7 installed the drivers required and the headset is successfully added.

    Now, I tried to connect to the headset using Bluetooth configuration dialog window.

    I did a right click on the icon of headset to Panel-> devices and printers.

    The right click is not display the option 'control' for the headphones.

    He showed that other options - "Create a shortcut", "Troubleshooting", "Remove the instrument", "Properties".

    So, I won't be able to connect my Bluetooth headset.

    I tried the same helmet on my friend's laptop computer.

    His laptop is running on Windows 7 Home Edition (32 bit OS).

    The connected properly Bluetooth headset and the option 'control' is also available on the right click.

    The 'control' option provided the Bluetooth configuration dialog window where I can use the "connect" button to connect the headset.

    Kindly let me know the resolution of the issue.

    If your computer has built-in Bluetooth features, you can enable or disable the functions by pressing on Fn + F5. If you press Fn + F5, a list of the wireless features is displayed in the window Radio wireless.

    You can enable or disable the Bluetooth features with a single click.

    To use the Bluetooth features, double-click the icon of Bluetooth Favorites on the desktop and follow the instructions on the screen.

    You can use the Wireless Radio switch to disable Bluetooth features. The wireless radio switch is usually located on the front of the machine. If you have trouble with the Bluetooth, make sure that the wireless Radio switch is set to position it.

  • After that I changed the Duplex parameter on NIC's Service console, I am not able to connect the ESX host

    Hi all

    Please help solve my problem.

    After that I changed the Duplex parameter on NIC's Service console, I am unable to connect the ESX host. How can I reset the 100 MB NETWORK card duplex. Can someone help me please.

    Concerning

    Vijay

    Hello

    As the bulb you have two problems that are not related.

    (1) duplex setting, your switch and NIC must match. If one is assigned to auto-negotiation, then the other must be set to auto-negotiation. Personally, I tend to let auto-negotiation unless there is an absolute reason to spend. If you then turn on the both sides of the interface, the switch port and esxcfg-NICS allows you to change the duplex, etc.

    (2) passwords for root are not related to the network unless you have also run esxcfg-auth authentication remote.  The only time I saw what you have here is when the system is configured to try to authenticate remote and not locally.

    The two problems are fixable by booting into single-user mode, set the duplex and reset the password.

  • TS140 will not be released in the second monitor

    I recently bought a TS140 intended for a workstation. I recently purcahsed two computer monitors, the two Gateway 22 "LCD (model KX2153). The computer is running on Windows 7. I have a montitor plugged into the VGA port, and the other is plugged into one of the ports screen using a DVI - D to display active adapter port.

    The computer recognizes the two screens, but there is no signal on the screen connected to the display port. The two works through the VGA, both port do not work by the display port. When you use only the display port, it gets still no signal. The monitor can tell when it has been disconnected from the display port.

    I was wondering if anyone had any advice. In the meantime, I ordered another card (this a VGA displayport) to see if the adapter is the problem.

    Too bad, the new displayport adapter worked!

    Hello

    Take the battery out of a set because they can interfere with each other. On the basis of each mouse
    should be a little button that you can push with a pen point or a trombone (small white button near the battery

  • hang the second monitor for slimline t3600

    Hello

    I am trying to connect the second monitor and upgrade to 3 GB RAM to 4 GB.

    Please let me know what King of the video card and the RAM will be I need?

    Thank you

    Here are the details of my pc.

    -Integrated 5.1 audio channels with front audio ports

    Here are the specifications of your HP Pavilion Slimline s3600t desktop. According to specifications, your system has a 180 Watt power supply. This power is very unlikely to support a low profile retail graphics card. You can buy a card personalized with reduced HP power but it is very expensive. This leaves the eVGA USB - VGA adapter. About $ 40 - $50, it's a bargain compared to your other choices.

    ==================================

    You may need to update your display and video driver

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded: run DriverView - define the VIEW
    for the drivers Microsoft hide - updated those without drain in their names. (Also updated
    the BIOS and chipset drivers.)

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
    video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
    cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
    This will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
    own the software and drivers and all other main drivers that you have.

    Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
    (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
    updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

    Always check in the Device Manager - tab drivers version you install actually shows up. This
    because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
    pilot - reboot - check that it is installed and repeat if necessary.

    Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    Updates, this leaves ONE of Windows updates, but it will not install the drivers who will be generally
    be older and cause problems. If updates offers a new driver and then HIDE it (right click on it) and
    Then, get new ones manually if you wish.

  • not able to connect to the database users

    Hello


    OS Oracle Solaris on SPARC (64-bit)
    database version 10.2.0.2



    There was a problem, one of the database, most of the applications were unable to connect, only 1 or 2 managed applications to connect, which totalled around 4 to 6 hours. Once the database has been recycle everything was ok, so what could be the reason? I have too many words from sr oracle, oracle specified as there was a sql with 13000 executions, also as 2 users have tried to update the same row in the table, so that users must commit frequently, just read the lines highlighted. My question is if there is a conflict of line, that would restrict other applications to connect to the database. And after reboot, everything was normal. I m wondering as is the resource_limit or max execeeded processes at this time this is why not able to sign in as user applications oracle unable to generate new processes.

    As I mentioned in the SR #, users could not establish connection to recycling of the database at all. So what is the root cause?

    Not so sure. Is this connection to database, or application? The OP wrote "+ one of the basis of most of the applications were not able to connect, only 1 or 2 applications has managed to connect +", don't know what that means exactly, depends on how the application manage the connection. It can start with the search/update of this table where the problem may come from.
