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

  Hello.

  I just bought a SATELLITE L855-118, with ATI graphics card today, it was between this and another of them, but I know that you have problems updating graphics drivers on a portable Sony.

  I did a restore point.

  So I uninstalled the ATI catalyst graphics card and then did a sweeper driver and rebooted and then installed catalyst 12.6, installed fine, but my screen went to the maximum brightness and I can't adjust, BRIGHTNESS osd is displayed but the brightness of the screen does not change.

  So I used my restore point.

  This time I crushed the catalyst 8.9 with 12.6 stock, still cannot adjust the brightness.

  Someone knows how to solve this problem.

  My spec full in the link below.

  You mean that you can not use the Fn or Fn + F6, F7 button combination?
  Do other combination works properly?

• Cannot run the screen saver because it requires a newer video card or one that is compataible with Direct3D.

  Hello

  I recently rebooted my computer; (Packard Bell) and now cannot run games or screen savers because it does not start. I think my problem has something to do with a Direct3D card? When I run screensavers, I get this message:

  Cannot run the screen saver because it requires a newer video card or one that is compataible with Direct3D.

  I have the impression that sound when I run the 3D games, such as minecraft or GMOD.

  I run on Windows Vista Edition Home Premium and does not do anything but re - install my computer because it wouldn't start.

  It is not as if the graphics card is not there, so I'm really confused!

  Please help me, like playing games is my favorite thing. ;)

  I also ran minecraft to double check and I got this error code:

  Bad video card drivers!

  -----------------------

  Minecraft could not start because it did not find an accelerated OpenGL mode.

  Generally, this can be corrected by updating the video card drivers.

• XPS 14 cannot adjust the brightness

  Hi all

  I have 10 windows and I can't adjust the brightness with the latest video drivers (Dell and Intel\Nvidia also).

  Can you help me with this problem?

  I found another thread on this issue which solved my problem. 'en.community.dell.com/.../19526400'.

  I have Intel UMA graphics card and had to update a record.

  I needed to change only the first line in the registry: [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\ {4d36e968-e325-11ce-bfc1-08002be10318} \0000] "FeatureTestControl" = dword:0000ffff

  Here's a good page to Microsoft on how to change your registry file. Be sure to follow the steps to back up your registry first.

• 15 - r254nu:. Cannot adjust the brightness on Windows 8.1

  So I tried different ways to resolve this issue, but again the light cannot be turned on/off. Help, please!

  

  Hello:

  There are two Intel driver links to the choices on your laptop support page.

  I explored the folder of the driver of this driver file to support your laptop and driver page, and it is suitable to use driver.

  This package provides the driver that allows graphics Intel high definition (HD) in the notebook models that are running an operating system supported. If the video output high-definition multimedia interface (HDMI) is supported, this package also installs the HDMI Audio Driver.

  File name: sp69589.exe

  The hardware ID for the Intel graphics card in your laptop must be one of these...

  ;=====================================================================
  ;    Windows 8.1 install
  ;=====================================================================
  [IntelGfx.NTamd64.6.3]

  % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_220F103C
  % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2213103C
  % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2210103C
  % iVLVGMT0% = iVLV2M_w81, PCI VEN_8086 & DEV_0F31 & SUBSYS_2214103C

  You should see a device from Intel HD graphics instead of the graphics card base of Microsoft, and unless you can get the graphics driver to install you will not be able to adjust the brightness of the screen.

  Is the above driver do not install the Intel graphics card automatically, try to install the driver manually by navigating to the folder of the driver that is created after running the above file.

  Confirm that the hardware for the Intel graphics card ID matches one of the above since the driver installation information file that I posted.

  To find the ID of the hardware, Device Manager, click the graphics card Microsoft Basic.

  Then click on the Details tab in the upper part of the window Microsoft Basic graphics card.

  Now you should see a drop-down list of property and it is set by default to the Description of the unit.

  On this list and select the 3rd point (Hardware ID).

  Confirm that the hardware ID, you see there is one of those listed that I posted.

• Cannot adjust the brightness after installing Windows 10

  Hello. I have a Dell XPS 15 L521X.   Recently updated to Windows 10 and I can adjust is no longer my brightness upwards or downwards.

  Now the screen is quite low.  I'd say about 30-40% brightness.  10 widows I found about 5 different places to adjust your brightness and I made sure all of them have been set to 100%.  I have my power plan to high performance and I went into advanced settings and turned off Adaptive brightness and made sure that the brightness of the screen the two Dim brightness set to 100% on battery & are plugged.  Rebooted and still dim.

  My question is, on Dell laptops, Windows has full access to the brightness control?  Or Dell replaces Windows with their software customized for the display settings?   When I bought this laptop in 2012, the software, at the time, was called Dell QuickSet.  What is the responsible application of brightness of the screen control?  And is it necessary?

  Thank you

  Mike

  I am also having this same problem. My brightness has been set at max after update and it hurts my eyes. I did it... Control Panel > Device Manager > graphics cards > Intel HD Graphics 4000 > pilot > Update Driver > Browse my computer > let me pick. Choose Microsoft Basic graphics card.

  After doing this, my problem was solved, and I was able to adjust the brightness of my screen again. BUT if you play games on your laptop, it will cause display problems in your game.
