Cannot adjust brightness levels

I have an HP Envy 14 Notebook and as of recently, I cannot lower or higher my brightness settings. This laptop has Windows 7 Home Premium installed.
I recently updated my graphics card, or rather, the AMD Catalyst Control Center. Before installing that, the brightness control was working perfectly fine. Afterwards, it just stayed on 100% brightness and its killing my eyes. I tried going in to Control Panel > Device Manager > Monitor > Generic PnP Monitor > Uninstall > Scan for hardware changes, nothing worked. I tried adjusting the brightness level from both AMD CCC and Intel(R) HD Graphics, nothing. I tried booting up in to safe mode, still the brightness settings would not change. As it is right now, because I cannot stand the insanely bright screen I had to go in to CCC > My built-in displays > display color > Contrast to 20. It definitely dimmed the screen by a lot, and I can see a lot better now but my eyes still somewhat hurt from the incredibly bright light. Its a workaround, but I rather have this solved than have a workaround.
And the whole reason why I even updated the graphics card was because I continously have stutter when playing games and during cutscenes, but it seems that problem is still around...

Hi ZeroArmada,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP ENVY 14 Notebook and getting a blank or black screen on startup. Try performing a hard reset. When performing a hard reset please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices. If that does not help try to turn on the computer you start to press F11 repeatedly till the menu opens. You can do a system restore. Here is a link to a document on how to rollback drivers in the device manager.
Thanks.

  • Cannot adjust brightness on win 8.1 x64(i have a WEIRD solution)

    macbook pro 13' with retina display
    win 8.1 x64
    i cannot adjust the screen brightness
    i turned off "adjust my screen brightness automatically".
    i reinstalled boot camp.
    i reinstalled the drivers of intel video card(5100).
    the above solutions help nothing.
    BUT, at last, i found a WEIRD solution to fix this issue:
    1. adjust your screen resolution.
    2. select an option of resolution(whatever you want, select an option casually).
    3. click "Apply"
    4. press ESC(cancel to change screen resolution)
    5. now, adjusting screen brightness is AVAILABLE!
    now, my question is: HOW TO FINALLY FIX THIS ISSUE?

    I had a similar issue when I installed Windows 7 Ultimate 32 bit on my last MacBook Pro. You know how Bootcamp downloads the support drivers for your machine? Those drivers are the instructions for the each component. I messed up a step on installing it and my secondary click wouldn't work, I couldn't adjust the brightness of the screen or keyboard, and I couldn't run games because the drivers didn't install correctly for my machine. You need a USB drive, an iSO Image, a blank DVD or CD with 4GB or more storage, a disk drive with read/write capabilities, and your Mac. If you have a desktop like the iMac or Mac mini, I believe you need a USB mouse and keyboard until the drivers are installed. Follow this video and in it there are two links, one for uTorrent and one for Windows 7 Ultimate 32-bit. If you don't have uTorrent, download it and install from the link. Ignore the link to the Windows 7 32-Bit download. I found a 64-bit version if you'd like or browse the piratebay for windows 8, but I highly suggest a 64-bit version as I believe they can handle more and do more compared to a 32-bit.

  • Cannot adjust brightness in windows 7 64bit

    Hi everyone, thanks for reading!
    I cannot adjust the brightness in windows 7 64bit with my keyboard. I have tried reinstalling the latest bootcamp drivers but it still did not work.
    The brightness of the monitor is just too bright for my eyes...
    Is there anyway I can fix this problem? I really appreciate yr help!
    My computer is an mid 2011 27" iMac. It has a i5 CPU, originally 4GB ram but i added another 16GB ram to it.
    Thanks for your help again!

    is your problem that you can't adjust the brightness from some keyboard shortcut or that you can't adjust it by any means in windows?
    I have the same generation imac just 21" model and the apple support hardware video card driver auto adjust the brightness for me if one don't use the apple driver and let windows install some generic amd video card driver that may not be the case
    check the amd catalyst display settings for more info also about brightness

  • Cannot adjust brightness after display driver update on Satellite L855-118

    Hi.
    I just bought an SATELLITE L855-118 , with ATI graphics today, it was between this and another one, but i know you have problems updating graphic drivers on a Sony-notebooks.
    I made a restore point.
    So i uninstalled the ATI catalyst and then did an driver sweeper, and re-booted and then installed catalyst 12.6 , installed fine, but my screen went to maximum brightness and i cannot adjust it, the brighness osd appears but the screen brightness does not change.
    So i used my restore point.
    This time i overwrote the stock catalyst 8.9 with 12.6, just the same cannot adjust the brightness.
    Does anybody know how to fix this.
    My full spec in the link below.
    Satellite L855-118 - Product Specifications - Toshiba
    Thanks
    John.

    This is not going to help you, but I have details on the internals of brightness control on this machine.
    On other notebooks I've worked with, the hotkeys generated an event that was directly handled by the firmware (ACPI) that changed the brightness; this was done to avoid putting into the AMD video driver any system-dependent code.
    On the L855 the ACPI does not really handle the notification, it just generates another event that is supposed to be handled by the video driver. For more technical details see:
    [http://thread.gmane.org/gmane.comp.video.dri.devel/71255]
    Now this is where it gets ugly: if brightness control is indeed system-dependent (e.g. you have to poke some random GPIO) then the AMD driver will never support it (it would have to know the details of each and every model in circulation).
    The good news - at least for Linux users - is that AMD just published the specification of its ACPI interface:
    [http://thread.gmane.org/gmane.comp.video.dri.devel/71697]
    I've already done some experiments with it, keep an eye on the thread.
    This may (or may not...) lead to a usable brightness control *for Linux*, but the same information *may* be used to create a similar driver for Windows.

  • Probook 4540s- cannot adjust brightness

    after installing windows 7 i cannot adjust my screen brightness.

    You're very welcome.
    There are two graphics drivers for your notebook -- AMD or Intel.
    Whatever one you installed that gave that error, try installing the other one and see if that one works.
    One of them should work.

  • Cannot adjust brightness windows 8

    Hi

    Please help 
    Thank you !

    hi erin654,
    Welcome to the Forums.
    It's possible that one of the updates that got installed changed the display driver that controls the brightness functionality
    Things that you can try:
    1. Press the Windows logo key‌ +R and type devmgmt.msc. On the Device Manager, navigate to the Display Adapter (right click > choose Properties) and on the Driver Tab, check if the Rollback Driver is clickable If it is, do a rollback to restore the previous display driver and try to adjust the brightness
    2. Navigate to the Control Panel > Programs and uninstall the display driver and reboot. Navigate to the D:\Drivers folder and locate the AMD Display driver installer or download and run the file below to re-install the display driver.
     ATI Catalyst Install Manager (Chipset, AHCI, VGA)
           Microsoft Windows 8 (64-bit)
           Version: 8.982.7.1
    After installing the driver, reboot the machine and try to adjust the brightness.
    Alternatively, if you're pressing F11/F12 to adjust the brightness, try to open the ATI Control Manager and adjust the brightness settings there.

  • Cannot adjust brightness on R61 with Windows7

    I installed windows7 build 7100 and then cannot adjust the monitor's brightness. Can some one help? Thanks.

    Had the same issue with the installed driver. I upgraded to nVidia 190.15 (beta - modified by Guru3D ) and now works fine. In case you need WHQL, try the latest stable driver from the same site (modified inf to work on mobile/quadro cards)

  • 27" ACD as second monitor -- cannot adjust brightness

    I've connected a 27" LED ACD to my 27" iMac as a second monitor, but the keyboard commands for adjusting brightness do not affect the cinema display. I understand a common cause for this is that the USB isn't connected, but mine is and I can verify it is working because I have an external HD connected to the USB port of the ACD, and the iMac recognizes that it is connected.
    Also, if I go into Display Preferences then I do see the Brightness slider for the second monitor. This is currently the only way I can adjust the brightness of that monitor.

    True, Unless there's a shortcut for that, the only way to adjust the brightness of the second monitor is by using the display preferences . same here with a MBP / 27" display.

  • MSI 975X with Realtek HD drivers - cannot adjust recordin levels, stereo mix gra

    Called MSI and they could not help me.
    Have XP and 975X Power up board. I know there is a shortcoming in the Realtek software drivers as per what I read on Google. Have not found a fix, wonder if others have.
    Recording Sliders (volume) are grayed out and not move-able (locked) for recording volume for anything except Master Volume.
    Cannot adjust line-in volume or stereo mix for recording.
    Ideas without putting in a 3rd party card?
    Thought I had this working once but perhaps I never did.
    Tried uninstall, reinstall, safe mode install, old drivers, new drivers, blowing away drivers, every checkbox under the sun. Thought I found a registry fix somewhere but I cannot find now.
    Thanks so much
    Peter

    Hello Peter,

    Recording Sliders (volume) are grayed out and not move-able (locked) for recording volume for anything except Master Volume.
    This does not have anything to do with your mainboard.  It is basically a limitation of the Realtek Sound Drivers for Windows XP.  Google "Realtek Mixer XP" and look at the images you find.  No individual recording sliders to be seen, no matter what board. Here is an ASUS Example Screenshot: 
    If you need to adjust microphone input volume, go to the Playback part of the mixer and scroll it to the right using the <> buttons until you find a slider for the jack you microphone is plugged in (compare picture above, I don't have an MSI Screenshot at hand).  You can enable microphone boost here and adjust the input volume.  The same is true for Line-In.
    In case of microphone problems, make sure you microphone is calibrated.  There is an application in the Realtek installation folders called "miccal.exe".  Run it to calibrate your microphone.

  • Cannot Adjust Brightness

    The Fn down and up keys no longer adjust the screen brightness... the brightness icon and bars appear but it has no effect on the actual brightness of the screen. Setting the power management in the Lenovo energy managment screen also has no effect... I've uninstalled and reinstalled the power management software to no avail.
    Any ideas?

    Backup your system and restore to default state - does the problem still remain?

  • Cannot adjust brightness; it's getting weird.

    So for the past day, my 13" Macbook has been acting very strange.  When I first boot it up, the screen is at the brightest setting; however, when I attempt to change it, the little brightness sun thing says that there is no brightness.  When I then shut my computer (not turn it off, just close it) and open it again, everything is dark and it's at zero brightness.  This is getting pretty annoying.  Does anyone have any idea what could be causing this or how I could fix it?  If so I would be very thankful and overjoyed!

    thanks for the reply
    actually it's more than a year, and the warranty already ended.
    some technicians told me it might be the battery. Honestly, i have no idea about the PB's battery. Does it comes with one major battery or dual or so on. 
    Really frustrated now, and wishing a miracle... (

  • Cannot adjust brightness in new Windows 10 Update

    Bravo! This solved the problem with a very dark built-in display and weirdly working brightness F-button on my VAIO VPC Z21 after otherwise smoothly upgrading it to Windows 10 couple of days ago. Thank you!

     
    Hi JacobRocks12!
    BuFan is right about the official drivers and software update for Windows 10 operating System. Currently, Sony is testing Vaio computer to the new updates. It takes time since Sony needs to coordinate with certain vendors to validate those updates.

  • Have Upgrade Graphic Card Driver, But Still Cannot Adjust Screen Brightness and Sleep Button Not Showing After Clean Installation of Windows 8.1

    I have done clean installation of Windows 8.1 on my HP Pavilion G4.
    Then I realize that I cannot put my computer on sleep mode and cannot adjust screen brightness.
    I understand that those problems caused by the graphic card driver.
    My computer is running on AMD Radeon HD 6400 series.
    Thus, I manually search on internet and found a latest graphic card update on microsoft site that is claimed compatible on windows 8.1 (link: http://msdn.microsoft.com/en-us/library/windows/apps/dn344644.aspx).
    I've upgraded it into the latest one. I've check on Device Manager, the driver is running well.
    But my problem did not solved!
    Please give me the solution!

    Hi,
    How about go to Device Manager, then uninstall Graphic driver and restart your computer, system will install its build in graphic drver. You can have a try.
    In addition, access to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Brightness and set its value to 100 for test.
