• HP Pavilion 15z Touch: screen brightness will not change

  When I use the keyboard commands to adjust the brightness of the screen, it does not work. When I go into the control panel to set the brightness of the screen remains the same. The adjustment bar will move from dim to bright but the brightness of the display will not change. How can I fix it? I've only had this computer for 4 days, so everything is still at the factory.

  Hello @KayLeeM,

  Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff.

  I came across your post about the brightness of the display and wanted to help!

  Try searching for the Device Manager in the Start Menu.  Then expand the monitors section and see if you have an option for Generic PnP monitor.  If so, do a right-click on him and generic PnP monitor enable, if not already.  Now, check to see if you can adjust the brightness.  If you're still having problems, then try to see the following resource and let me know how it goes:

• Dell XPS 14 brightness will not change / "Painting as" Image

  I just got a Dell XPS 14 Core i5 and the GeForce 630 M. I found that the brightness of the display does not change even if pressing the keys on the keyboard or adjust the slider on the screen the toggle to retouch the brightness comes. Thus, the keys work. I have updated the drivers for the 630M, chipset and Intel 4000 card. Also, I flashed the BIOS with the latest version. The Dell representative I talked to said that updating the drivers may solve the problem - it didn t. Then, through remote connection it did for me. No luck. So, what's the problem? Also, I have a weird and potentially related problem. All the images on the screen (bottom of screen, images in the browser, photo gallery, YouTube, etc.) have a look "painted" their. The videos are unstable and the images are very washed-out. Once again, after update, the problem persists. For me it is a hardware problem. Help someone!

  Thank you

  Type of system: XPS 14 L421X detailed description of the problem:

  The display is of poor quality with graphs, images, videos and texts appearing pixelated and grainy. The problem is particularly notable for graphics online / on the internet. The contrast is also apparently, make images appear as less detailed, almost like a screen 256 older colors. The problem persists when the video output is connected to an external monitor via a HDMI cable.

  The issue is subtle and may not be obvious to new users; Is why it can easily be neglected if not carefully read. I would recommend comparing the simultaneous side-by-side display of the same image on your computer and another computer files. In addition, display images at actual size of 100% in the comparison will help identify the problem. You should be able to see obvious color with gradients almost "oil painting" as artifact.

  After months of wasted effort with XPS support replace the LCD screen, install a new copy of Windows and video drivers, shipping my computer for the installation of Dell for 'analysis of expert' and even replaced all of the device, the problem has not been solved.

  A few days after updating my Windows to 8.1, I found the problem. Here is the solution: right click on the new button start click on "Mobility Center", under 'Color of the default' select generic color instead of splendid color. This will fix the problem.

  Hi @weiwei17,
   
  Thank you for visiting the HP Forums! A place where you can find solutions for your problems with the help of the community!

  I stumbled upon your post on the laptop and wanted to help you! I looked in your question about your computer laptop 14-ac014tx HP and questions with your upgrade to Windows 10. Try to use the Windows Update Troubleshooter to fix the problem.

  Here is a document that shows how update the drivers that do not work correctly with Windows 10.

  HP has worked closely with Microsoft on developing for Windows 10. Currently there is no driver available for your system. You can try and check at a later date, because I see new drivers all the time.

  Here is a link to the HP Support Assistant, if you need it. Simply download and run the application and it will help with the software and drivers on your system that may need updating.

  Thank you.

  I deleted the uploaded image independent of photos and the lock screen still shows the wallpaper I'm changing.

• G70 screen resolution will not change

  HP G70 - 257CL running Windows Vista Home Premium SP2

  Mobile Intel 4 Series Express Chipset Family

  Have this second hand with a broken screen. Until I could get a new screen, I used the HARD drive in another notebook successfully. Now reinstalled in the G70, have everything works fine except the screen resolution.

  Reports adapter Device Manager works correctly. I uninstalled and reinstalled, updated the drivers. But no matter what resolution to choose for the screen, it remains the same.  I've currently set to 1440 X 900, 32-bit color, refresh rate of 60 Hz. But what I get is closer to 800 X 600. And it stays that way, no matter what I put it to.

  To the best of my knowledge, I uninstalled all drivers associated with the other laptop, so there should not be anything interfere. Thanks for any help, that all the world can offer.

  Hi Barnaby,.

  It doesn't sound like an exorcism is necessary. From all I have seen and know the computers that he shouldn't do that. Before you call the Ghostbusters or a priest try connecting an external monitor to see if you have the same problems.

• Windows 7 splash screen will not change after the vista update

  After updating vista 32 bit to windows 7 32 bits, the splash screen will not change and he showed the vista boot. I read a lot of forum and the web page, but this solution:

  «.. . the dummies and bad start screen for Windows 7 is due to the locale entry in the startup folder, which could not be set when editing or rebuilding the BCD. When the locale is not found, Windows boot loader doesn't know what local startup folder to look for the animated bootscreen. Thus, in order to fix the boot screen so that the splash screen can be re-established, restored or reset to original animated Windows 7 boot screen, just run one of the following commands at the prompt with administrator rights:

  or

  BCDboot % WinDir % / l en
