Windows 7 sees my second monitor as "generic non - PnP" and will not let me set the correct resolution


I just installed Windows 7 Professional 64 bit on a new hard drive on my Dell Studio 540. The PC has a graphics card ATI Radeon HD 3450 and has a Samsung 226bw 22 "monitor on the digital output. This works very well, and has the resolution of 1650 x 4050. When I am running Vista (on the previous hard drive), I got a monitor flat 14 "old on the other out, and it worked fine (although at a lower resolution).

I added a monitor AOC F22s + on the other output, expecting to be able to put this to the recommended 1920 x 1080 resolution. Unfortunately, Windows has developed the driver for this monitor "Generic non - PnP" and will not let me set the correct resolution. To the maximum it will allow is 1600 x 1200, (as well as all other resolutions it allows) do not use the monitor at maximum capacity, which is the ratio of evil anyway, so the display seems tense.

I run Windows Update, so have the latest drivers. I tried to install the other drivers, but nothing helped.

I tried to unplug the Samsung monitor and restart the PC, so that the AOC, one was the only monitor it and he always had as 'Generic non - PnP' with the wrong resolution.

Someone at - it ideas? I'm at my wits end. AOC support did not understand and could only suggest that the monitor was faulty, but the place where I bought it insist that it works very well and so no Exchange or get a refund (no restocking fee, which is a RIP-OFF).

I really want to use both screens and would appreciate greatly any help that anyone can give. I hope I gave enough information. If I didn't, please let me know.

Thanks in advance,




It turned out that my VGA cable was wrong and that it was not send the right signal to the computer. The screen worked fine with a VGA monitor, but the PC has not said that the new monitor is a PnP I tried a different cable and it worked fine.

Thanks again to all who have suggested things.

  • Windows 8 will not let me move the AppData\Local folder to new drive


    I wanted to get my user account files from C drive which is a smaller SSD drive at most of my hard drive. I encountered several problems.

    A lot of trial and error, I was able to move each file of folder of the user account to an identical structure on my drive D (a "spinner"). Once I worked on all the kinks, everything worked without problems.

    However, I was unable to move the hidden AppData folder. I discovered there are three subfolders: roaming local and LocalLow. I was able to move LocalLow and roaming without problem. However, Local gave me problems.

    I discovered that the Local had some folders and files under it for which I have no permissions. Once I gained permissions for them, I thought I was on my way. The command to move the folder (using the Properties dialog box) has started working on the transition of 79 000 files. He moved all but 19 of them. He choked on all 12-15 files that have been opened and used by the system and the balance of the 19 had too long of a file name. So, I was disappointed.

    I then decided to create another administrator account and the sign of the current account and connect to the temporary administrator account that I had just created. I thought that I could then move the files because they would not be opened and used by the system. But, when I open the Properties dialog box, the LOCATION tab was gone, so I could not move the files.

    I need answers to two questions:

    • Why Microsoft would give the user a LOCATION tab with a NAVIGATION button, if it was impossible to move the AppData\Local folder?
    • Is there another way that a layman like me can change this setting? Can someone direct me to here? (Such as it is, 2 of the 3 AppData files are on drive D and 1 is always the SSD C drive.)

    Thank you.


    OK, I fixed using a symbolic link. I moved my complete record of users. Here are the steps I used:

    • Create a folder on the "C" drive, called "this_is_c" and create a folder on the disk "D", called "this_is_d" - it is only for identification purposes in the later stages.
    • Boot from the Windows 8 Pro disc. (In other words, will not start hard drive.)
    • Do not choose 'Install now' - choose ' repair you computer.
    • Then choose troubleshooting
    • Choose Advanced Options
    • Then choose command line
    • The player that appears corresponds to the player 'X' - which is the recovery disk.
    • Type "C:" to switch to the 'C' drive
    • Type "Dir" and see if you see the folder "this_is_c".
    • If you do not, continue to change letters until you see this folder.
    • It worked that the 'C' drive during this "repair" was maybe the same as my 'C' drive when I boot normally.
    • Find the "D" drive through the same process - that is, try to find the folder "this_is_d".
    • It worked that the "D" drive during this "repair" was maybe the same as my "D" drive when I boot normally.
    • Type this command: xcopy/e/k/o/h/b c:\Users d:\Users see the next chip
    • First drive name must be the name of the drive as the "repair" attributed to your normal boot drive 'C '. The second disc should be burned as it would be during a normal boot. So, in my case, these conditions were the same. Note: use a capital 'U' for users instead of lowercase 'u' in users.
    • Type "D" when prompted.
    • Type the following command: rd /s c:\Users
    • Type this command: mklink /d c:\Users d:\Users
    • Type this command: exit
    • Continue to start.

    This will create a symbolic link that will redirect all actions to or from users on 'C' folder in the new folder users on "D". In regards to windows system knows, he is still sending the disk of 'C '. It is just redirected.

    This works perfectly for me. I installed apps and run programs without problem.

    It's a sort of understand. But it works for me.

  • Satellite P100 - 194 PSPA6E does not start and will not let me install Windows


    I have a problem with my Satellite phone, witch, I got from my brother. I don't know what he did with it, but he does not know.

    When I start the PXE - E61 "Media test failure, check cable" appears. In the BIOS I put in the directory Boot LAN mode on the last position, but despite this failure E61 appears.

    I tried to reinstall Windows XP. The laptop started from the CD and the blue screen appeared and loaded XP drivers needed. But at the end of it, when you enter normally on the menu to choose where to install windows, the screen is black and in the upper left corner a small beam blinked on and outside and nothing happens plus.
    The same thing happens when I leave the laptop HARD drive and start again from the XP installation CD but this time without the HARD disc logically.
    So I thought that the HARD drive is broken and I put it in my desktop PC to test. I installed XP on the drive HARD Satellite in my PC, which worked without problems in my PC. So, I come to the conclusion that the HARD drive is not broken.
    And my BIOS Satellite detects my HARD drive and displays the name of it.

    But what is the problem with the laptop when it is not the HARD drive and BIOS show the good name of the HARD drive? Can someone help me please?


    The story is very strange boyfriend generally that the PXE error if the laptop tries to boot from LAN. But in the case where starting LAN source in unavailable, the PXE error appears and shows this message.

    Usually, the BIOS passes LAN Boot option because the other options are not active. This means that the CD/DVD drive does not any bootable disk and the HARD disk is dead.

    So, as you can see you hypothesis was right that the HARD drive could be faulty

    In any case, try to access the BIOS and set it to the default settings save changes and then try to reinstall Windows XP.
    You might also try another HARD drive, I know as your fist HDD recognized correctly but it s worth a try to test the 2nd HARD drive.

    What are 10 Windows users supposed to do when they are run this problem?


    As you know, Windows 10 has made it impossible to hide or ignore updates (or so it seems).

    I found this tool from Microsoft that allows you to hide updates that don't work, or mess up your PC if they work, (as a synaptics touchpad update has done on my laptop).

    I saved this tool on my PC for use in the future if necessary.

  • Windows thinks flash drive memory card reader - will not let me import the photos.

    I have Windows XP on my lap top. When I plug my USB memory card reader, Windows thinks that it is a flash drive, and if I try to open it, it just says: "insert in the drive. There is no drivers for the memory card reader - it was designed that way, I think. The memory card reader used to work fine with my laptop, but no more.

    Can someone tell me what's happened and how to fix it? Thank you.

    Just guess... could this be a hardware problem?

    If you have more than one port... try USB to another.

    Maybe you can connect the camera to your laptop via

  • Installation disk hard second - "Uninitialized" says and will not let me format

    In disk management, I see my new drive hard second 1 TB.  It recognizes the 931,51 Go drive, unallocated.  When I walk through the process to configure a partition and format, I get the following error message:
    "The operation cannot be performed because the disk is not initialized."

    I must have missed a step, but reading that I did it is not clear to me what I missed.  Help?

    Thanks in advance.  Branden

    Figured it out.  The player appeared in the red list a small arrow down through the disc.  By right clicking on the arrow pointing down, they gave me the option to "initialize disk".  Now am going forward with the formatting process.  Confused, but hope someone saves some time.

  • virus jumble all my file associations and will not let me reset them... upgrading to windows 7 will overwrite everything on my comp. including viruses?

    The virus is a popup window that said it was a windows xp security 2011.  I tried to end it in task several times Manager, then did a system restore.  After I did a system restore all my file associations were all mixed upward and every sense, I try to change the associations, it won't let me.  It doesn't let me even open system restore or something like that.

    something special I have to do that if it is a laptop?

    I have a dell xps m140

    I expect BugBatter to answer here... but since it's been several hours and it didn't:

    before considering a change/upgrade of the operating system, you can check if you can solve the problem by following the directions/procedure listed here:

    before you say it cannot be done, take note of doing things exactly as specified... in particular, I would like to highlight the following points of special 3 which are:

    (1) If you are unable to download MBAM directly on the infected computer, you should download on another computer and then transfer it (via key) to the infected machine.

    (2) given that .exe files does not work on your computer, you will need to Rename the mbam-setup installation file . exe:

    mbam-setup. com:

    (3) Similarly, after installation of the MMFA, you will need to Rename it to mbam. exe for mbam. com in order to run it.

    Keeping these 3 points in mind, go back and follow, step by step, the procedure in the above link.

    NOTE: If Bugbatter here meets the time wherever you are reading this, then please follow all what she said which differs from my suggestion.
