Resolution with HP2311x and HP ProBook6455b series laptop monitor configuration problem

Hello

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

Maximum resolution is 1024 x 768

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 1024 x 768.

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..
http://support.portrait.com

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.

  • IDT Audio Codec time Sound speakers but not with headphones on ENVY DV7 series laptop

    I bought my laptop not more than two months ago. Its perfectly played through my helmet literally the day before yesterday.

    Only two changes have occurred since then, first of all I accidentally plugged my headphones into the external microphone jack, then I updated the 'Music' for Windows 8 PC application.

    After my sound stopped working. I restored my PC to a restore point dated before its no longer works in my helmet, however resonates once again that in my speakers (when my headphones are disconnected). When I plug my headphones, sound no longer plays in my speakers but no sound from my headphones either.

    How can I get audio to play through my headphones?

    Product name and number: Envy of HP dv7 Notebook PC C2h74UAR #ABA

    Operating system: 64-bit Windows 8

    Error message: None

    Changes: 1) update "music" app for Windows 8

    (2) accidentally plugged in headphones and external microphone jack

    Hello

    Try the following.

    First of all, download and reinstall the Chipset driver at the following link.

    Chipset Driver - Windows 8

    When reinstalling, restart the laptop.

    When windows has reloaded, download IDT Audio Installer on the link below and save it in your downloads folder.

    IDT Audio Installer - Windows 8.

    One time finished, open windows control panel, open Device Manager and open sound, video and game controllers.  Right click on the IDT device and select uninstall - also, you should get a command prompt to delete the current driver, check the box allow this and then proceed to uninstall.

    When you're done, shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

    Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

    Allow Windows to fully - charge it will automatically load an audio driver, but let just this complete.  Then open your download folder, right-click on the IDT Installer and select "Run as Administrator" to launch the installation.  Once this done, do a right-click the speaker icon in the taskbar and select playback devices.  'Speakers and headphones' left click once to highlight, and then click the Set Default button - check if you now audio with headphones.

    Kind regards

  • Image automatically changing the resolution with HDR and Photomerge in CS4

    I am trying to create HDR images and Hi Res Panoramas using Photoshop CS4. It seems that the resulting image is a much weaker than expected resolution (that is, the image has been reduced by 50% and changed at 240 dpi). I can do the thing smame on my laptop without problem, but may not know why it does not work on my desktop.

    Is there a preference that I missed?

    I use DNG images processed in lightroom.

  • Problem with Latitude E7440, dock E-series & external monitors

    Hello

    I just upgraded to a to an E7440 E6410. I have two Dell 2007FP monitors connected via DVI on a docking station E-series E-Port Plus. These monitors native resolution is 1600 x 1200 @ 60 Hz and my old E6410 was able to run this very well. The new E7440 refuses however to note that 1600 x 1200 is available and that there is an upper limit of 1280 x 1024 @ 60 and 75 Hz. The Intel graphics properties app shows 1600 x 1200 @ 60 Hz is a mode of the monitor support in the Information Center section, but it won't let me select it in the Display Options section.

    Anyone know if it is a fundamental limitation of the docking on the new connector 7000 series or if I just have something wrong set somewhere? All the drivers are up to date for what is the Dell support site is... The computer is running Windows 7 64 bit if that makes a difference.

    Thanks & best regards,

    Martin

    Sorry - should have come back earlier than my IT guy at work found the "fix." There is a updated driver that is for the E7440 but doesn't show up if you are looking for updates of E7440 (?). In any case, I had the drivers are required to:

    While the link is E5540 area, the driver is for the GPU Intel HD4400 located in the E7440 as well. This has fixed the problem on all the E7440s that we have here.

  • When I go on some websites (such as cricinfo), I am redirected to a page of 123 find. I don't have this problem with IE, and when I re - install firefox, the problem reappears

    If I quit firefox and then restart your computer and access the page, I can go to the web site. Then very quickly, the 123 find program takes over.
    This happens at home, I have all the info here.

    Finally, the problem is solved by running malwarebytes. I've deleted and reinstalled firfox and the problem reappears. This occurred because the Trojan horse was in the plugins folder that was not deleted when firefox has been removed.
    After that the Trojan horse has been deleted by malwarebytes, the problem is not happening yet.

  • Since the installation of Mac Mavericks all my friends with Macs and I have problems with the cursor disappears, that in Firefox, Safari is very good...

    I stopped using Firefox as nothing I've done has corrected this problem. I tried to close Firefox and restart it, I erased all my Add-ons and then added adblock back (it's the only one), but it still does not work. I deleted files so that I have more space - I can't think of anything that works. I talked to four of my friends with Macs and they are all having the same problem with Firefox since the Mavericks.

    Cursor disappears huh? It's quite strange. All of the compatibility of the Mavericks can be followed in [Bug 883824]

    Try this work around:

    1. Go to Firefox > Preferences > advanced > general
    2. Always check "use the cursor keys to navigate through the pages.
    3. Press OK.

    Or try the Mac preferences noted here: https://discussions.apple.com/message/23542890#24471966

  • Why some functions of "click on" does not work with Firefox and Ebay and my mailbox?

    When you go to my mail (especially Yahoo mail) I can't click on the boxes that allow me to delete or anything else. In addition, I can't hardly use Firefox at all with Ebay and other sites because of a similar problem. For example, the cursor will not change even a 'hand' on 'Sign In' on Ebay, or it will allow me to change the page number, if I have multiple items to sell or buy. I had to change all my Bill pay sites for IE for this same reason. You have any ideas? I am currently using Firefox 17.0.1.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

    • Do not click on the reset button on the start safe mode window or make changes.

  • Problem with T400 and external monitor (1920 x 1200 resolution)

    Hello

    My laptop:

    ThinkPad T400 2767-C99 * (graphics: ATI Mobility Radeon HD 3470 256 MB / X4500MHD (Switchable Graphics)), OS is Windows XP

    I just installed the latest video driver from lenovo page (which also installs "ATI catalyst")

    Externale monitor:

    I just bought a Samsung SyncMaster 2443FW, 24 "TFT monitor with a maximum resolution of 1920 x 1200

    Problem:

    Monitor works fine with my new T400s and my old Acer laptop. However, with my T400 (described above), I can't do the monitor uses the 1920 x 1200 resolution. However, all the other ugly resolutions so I need it to work with 1920 x 120

    -If I change the resolution of right on the desktop of Windows XP (and then properties-online settings) and set the screen on 1920 x 1200 resolution, then my monitor used only a lower meanless (1440 x 900) and effect of scrolling as I move my pointer on the screen

    -If I use the ATI catalyst software to set the resolution, I can only chose smaller resolutions (he not go 1920 x 1200)

    Questions

    Is it a hardware (maybe the graphics card does not support 1920 x 1200) or a software problem (maybe a problem with the driver) or just a matter of adjustment?

    What can I do?

    Help would be much appreciated!

    * Original description: 2767-2JG base: T9550(2.66GHz), 4 GB of RAM, HD 250 GB at 5400 RPM, 14.1 LCD in 1440 x 900, 256 MB ATI Radeon 3470HD, CD-RW/DVD-RW, Intel 802.11agn wireless, Bluetooth, Modem, 1 GB ether, UltraNav, chip dry, RPF, camera, 9 c Li - ion, BACK license

    Problem solved:

    I was using my old monitor vga cable that doesn't use 14 pins (worked fine with my T400s and Acer laptop - but not with the T400).

    => When I switched to cable 15-pin that came with the monitor, the problem was gone!

  • PSE 8 and high resolution with W7 compatibility

    I just upgraded from PSE 5 to 8.  I'm running on a laptop with W7 and screen resolution 1920 x 1200.  In order to make the menus and readable text, the system is fixed at 150% in the control panel.  It seems to work correctly with Office applications and other programs.  Unfortunately, even if the Organizer page is ok too, the menus page editor and fast editor are reduced to the right.  The menus and icons are so small, it is difficult to navigate and wierdly the cursor appears as three identical features images.  I tried to reduce the 150 to 125% but then the Organizer is affected and there is little improvement to the editor except that the cursor normally shows.  I had encountered the same problem in PSE5 but thought it was a thing of W7 and that the upgrade would be sorting.  Feeling poorer and not further forward.  Well, any help would be appretiated.

    There is no work around for the symptoms you see.  Adobe refuses to follow the standard Windows to allow larger values for the display DPI (dots per inch).  Apparently, Adobe doesn't care enough about usability, especially for those of us with eyes of aging and high resolution displays.   See this FAQ for more than a few details:
