Problem-solving with HP2311x and ProBook6455b

Hello

I have a problem-solving with portable HP2311x and ProBook6455b.

Maximum resolution is 1600 X 1200

Current display driver is ATI Mobility Radeon HD 4200

However, my HP monitor supports the 1920 X 1080.

I used only the external monitor without using the laptop monitor and the maximum resolution is always to 1600 x 1200.

I also downloaded the drivers recommended by HP, but it does not solve the issue.

I also tried with the drivers provided by AMD, but I get still more low resolution (1280 x 768) because the driver software detects is ATI Mobility Radeon HD 4250

When I try to use the AMD Vision Engine Control Center stops unexpectedly

I have conteacted
Portrait Displays, Inc..

But they suggested me to contact HP because they were not able to solve my problem.

Any help will be appreciated.

Kind regards.

I understand that you are not able to use the full resolution of the monitor even when the screen of the laptop is out of the question.

Ensure that the system has the right driver for the monitor found here.

You can try the support business forums as it appears that the two components are business models.

  • problem encoding with word and pdf doc - error message - file conversion - Select encoding to make your document readable

    Hi, until an hour ago, I had no problem opening documents adobe, or word documents, however, when I try to open a pdf document is opened correctly, I have to save it, and then open with adobe, when I try to open the Word document of display of the error message - file conversion, select the encoding that makes your document readable? help please how to do everything back to normal?  I think I caused the problem when I tried to open a Word / PDF of my removable flash drive, can someone please tell me how to solve this problem, without a questionable download?

    Can I save as and then open with - and pdf opens the file - but before that I didn't have to do it just opened automatically

    Thank you.

    J

    I just stumbled upon this problem there is, it's an easy solution to calm. If it's a .pdf to locate the file right click and select open with, then choose program select by default, choose the adobe reader software. What it does for each .pdf file it will use adobe reader instead of trying to use the wrong program to open the file. Same thing with .doc and .docx files only instead of adobe reader choose microsoft word

  • I've updated the plan of the photographer and since the download, I had problems nonstop with fluidity and now the bridge is not displayed large previews, a few thumbnails. I restarted and reset the tool, is there anything else I can do or should I cancel

    I've updated the plan of the photographer and since the download, I had problems with non stop with fluidity and now the bridge is not displayed large previews, a few thumbnails. I restarted and reset the tool, is there anything else I can do or do I cancel my subscription to the CC and return to the CS6?

    The problem of fluidity can be the result of a graphics card problem:

    Try to uncheck the box in the preferences > performance > graphics processor use, then by restarting Photoshop. If this solves the problem, check with the manufacturer about a possible update.

    On the bridge: when you select an image and press the space bar, what happens?

  • Problem webcam with Skype and MSN messanger on Satellite A300

    Hello.

    Well. The Australia contacted Toshiba. and got some information.
    Well, the person I spoke to said that he would try to find the drivers on the European site of Toshiba, which he did. And he said to uninstall the software from my camera assist.
    So I did, downloaded the new version, to install it. But I always get problems, saying that windows vista family premium, a USB device, does not work and windows does not recognize it.
    And also, had a driver error, saying: open the driver software or reboot your computer.

    Went on the forums of Toshiba and cast an eye, did show on their, but could not seem to find answers, and done in the last week or two.
    I just want, use Skype and MSN messenger.
    But if I can't get these problems must be solved, then no interest to install, probably does not work and haven't tried this feature yet on my machine.

    One had similar problems with their Toshibas? and where do I go from here.
    Really, which extends from my head and don't know what to do?
    The guys said maybe to make a recovery disk, but really don't want to go that route.

    It would mean having to spend hours to reinstall everything, and I don't really have the time to do at the moment.
    Very busy at the moment. If anyone can offer any other suggestions or where do I go from here?

    Had this problem when I got out of the box and purchased from Harvey Norman, Burnie, Tasmania.
    Marvin has soon.

    PS: If someone help, pourraient they send me an email to [email protected], in Australia, if they have the same problem and how they got around that one. !

    What model Toshiba do you have?

    Are you sure that the USB device is the webcam? Have you checked the Device Manager?

    * Download driver Chicony Webcam set to update from http://203.56.127.6/driver_download/Public//p2_all/ChiconyWebcam_v1.7.175.0123.exe
    * Install the Service Pack 1 of Vista, or Vista Hotfix KB934374: http://support.microsoft.com/kb/934374 (KB934374 is included in SP1)
    * Update your e-mail software (MSN/Yahoo Messenger, etc...)
    * If you have another program that can use the webcam (e.g. Skype), make sure that they are completely closed and not, sitting in the system tray.
    * Try to close the bar Assistant camera on the left side of the office.
    * To stop the Camera Assistant software from running at startup, run Regedit and delete HKLM\Software\Microsoft\Windows\CurrentVersion\Run "Camera Assistant Software".

  • problem installing with C4480 and Time Capsule

    I'm putting in place a new Photosmart C4480 to use with my computer laptop MacBook and my Office PowerPC G4 tower. When I connect the printer directly to the G4 using the USB cable, it works fine. But when I connect to the USB port of my time Capusule the C4480 (which is connected to the G4 by ethernet cable) G4 can't find the printer. However, I can print wireless from the MacBook. This configuration has worked with my previous Epson printer. Is there anything else I need to do? Thanks for any help/suggestions.

    I just answered my own question - I didn't notice the "Hello Printers" in the "printer" drop-down menu. Selecting the C4480 in this option solves the problem. Thanks anyway.

  • Problem-solving with games on windows 7

    I have problems with the games running in mode full-screen. I've always set continental as the lowest for better performance but when I changed the resolution what that it is less than 1366 x 768, I lose about 3-5 inches of space on the screen on both sides. I solved it once (don't know how) but I had to completely reboot my computer everything. Help, please.

    I am runing a TOSHIBA Satellite L455D with an AMD Sempron (TM) TR-42 2.1 GHz

    2.00 GB of ram

    32-bit system

    an ati radeon 3100 series with the latest drivers installed

    Thanks to extensive research and experimentation, I found the solution for ATI cards.

    In order to make the games on a smaller to adapt to the entire screen resolution, you must change the settings in the catlyst control center or CCC for short

    to do this first open CCC making Sure you are under the ADVANCE options

    now, go to desktop properties and change the resolution to one that is less than the native resolution of your screen.

    now go to the screen of desktop computers and screens. Right-click on your MAIN monitor (in case you use 2) and click on configure.

    Now you should see some tabs. go to the tab under what it should be several options avalible who say full-screen centered (or sometimes maintain proportions) the attributes, click on full screen, then click on apply. NOTE: If the options are grayed out always try to go to another lower resolution, if this continues to be gray, consider reinstalling or updating your drivers.

    now reset your resolution to its native and start a game that does not whole screen. your moniter should now be completely 'filled' with the game.

    Please note that some games still does that way because of the programming of the game. Include peggle deluxe, bejewled, bejewled 2, plants vs zombies and other similler arcade-style games.

    I hope this helps.

  • Problem-solving with Windows 8.1

    I just changed my HDD for one SSD and re-downloaded Windows 8.1 and I have problems with my resolution.

    It does give me only 2 options for resolution, 3200 x 1800 and 1024 x 768 (which it says is recommended). When I turn it to 3200 x 1800, everything is tiny.

    Where's my resolution (3840 x 2160)? Why is not just "an option? Any ideas on how to solve this problem?

    Install the chipset drivers first.  Then, restart and install the Intel video driver.  Finally, restart and install the nVidia Driver.

    No, I have not. I didn't know that I should...

    ... If anyone can give me a url where I can download what I need and where to install it, I would be delighted.  As I understand it, I would setup these tools in the machine virtual, right?  Once I realized that I have to install?

    With the virtual machine running, pull down the menu of the Virtual Machine and install VMware Tools, you'll see. Choose that and you should see the virtual machine window "click on install to connect the installation of VMware Tools CD to this virtual machine" and "In the virtual machine, open the application"Install VMware Tools"on"VMware Tools"disk." Installer is built into the merger application so there's nothing extra to get. Request for enforcement "install VMware Tools" and restart the virtual machine and you should get all the resolution choices you could want.

  • Problem with cs6 and alpha channel

    Help

    I upgraded from 5.0 to 6.0 CS cs Production.  I have several commercails with links to AE.mov files with alpha (codec animation million +).  I did this for more than 10 years, so this should be pretty basic.

  • Problems with MCE and G10-100.

    Hi all,

    I have an old G10 from 6 months which was very problematic to say the least.

    The main problem is with MCE and MY TV on the setup and constant of hanging and crashing when it is chosen also when it works sometimes in fact the image and sound just break up.

    I already reinstalled the recovery using CD, but nothing no is all the problems again.

    Any ideas?
    Thanks in advance

    Hi Paul

    One of my friends has laptop Qosmio and I had the opportunity to check this device. Beautiful part of material.

    On his unit, everything works fine. I checked the settings of MCE almost all because I was very interested in this topic. I didn t find something that can be like the issue you described.

    In my opinion if there is a problem after installing the OS using the recovery CD you should contact your local dealer or service partner. I'm sure that your device has a valid warranty and if there is a serious problem the warranty will cover all costs.

  • Acer Aspire S7-391 Windows 8.1 Issus with touchscreen and Trackpad

    Hello. I've just upgraded to 8.1 Windows, everything went well, but I realize now the touch screen is much less reactive than before, and many times I have to touch twice to make the action, something that never happened to me before with Windows 8.

    ¿Any suggestions?

    Another thing is the trackpad, which for example now does not scroll with 2 fingers and other things that did before.

    Thank you

    PROBLEM SOLVED WITH THE TOUCH SCREEN!

    Go to the Device Manager and look at the Human Interface Devices. There will be some USB devices that end up being the touch screen. If you change the options of feed on those so they don't turn off to save power, the problem should be solved.

    Please let me know how it works for you.

    I have an Acer S7 391.

    Greetings Dani56777,

    Thank you for using communities Support from Apple!

    I understand that you run Windows 10 and you must update iTunes to the latest version so that your iPhone will be recognized when connected. I do not know if you receive an error when you try to update iTunes or not.

    If you need information on how to update iTunes, please follow the instructions in the following link.

    Download the latest version of iTunes for Windows - Apple Support

    If you receive an error or alert, you can consider removing iTunes and all of its associated components and then reinstalling fresh iTunes on your computer. That would give you the latest version of iTunes. If you need execute this process, please follow the steps described in the following article.

    Remove iTunes Control Panel and its associated components

    Use the control panel to uninstall iTunes and software components in the following order:

    1. iTunes
    2. Apple Software Update
    3. Apple Mobile Device Support
    4. Hello
    5. Apple Application Support 32-bit
    6. Apple Application Support 64-bit

    On some systems, iTunes can install two versions of the Apple Application Support. What is expected. If both are present, do not forget to uninstall both versions.

    Do these elements in a different order, uninstall or uninstall only some of them. This could have unintended effects. After you uninstall a component, you may be asked to restart your computer. Wait to restart your computer until you finish remove all components.

    Remove and reinstall iTunes and software for Windows 7 and later versions - Apple Support components

    Have a great day!
