Windows 7 effect on the brightness of the screen

I just upgrade my Vista to Windows 7 on my Dell Inspiron 1420 laptop.  After installation, the brightness of the screen was significant reduced.  Screen brightness options show that it is on the intensity setting, and I can't increase the level.  It is certainly much less vivid, immediately after installed Windows 7.  Can someone tell me how to increase the brightness or should I uninstall Windows 7?

Sounds like you using the Adaptive brightness.

The screen on a laptop consumes more energy than any other part of the PC. Windows 7 automatically reduces the brightness of the screen if you are inactive for a period of time, just like a cell phone. Windows 7 adapts to your business intelligently. If the screen fades immediately after 30 seconds and you move the mouse to brighten the screen, Windows 7 waits 60 seconds before the display of gradation again.

  • PC/tablet-is there a laboratory touchscreen top that works on windows 7 / 8, where the screen can detach the keyboard to use in the form of tablets, or screen can be reached for keyboard vertically or horizontally?

    Labtop / Tablet question -I'm shopping for a new Labtop.    Is there a laboratory touchscreen top that works on windows 7 / 8, where the screen can detach the keyboard used in the form of tablets and then transformed (with long vertical side) and attached to the keyboard to type a length full page (8.5 x 11 page) and then returned (long horizontal side) one attached to the keyboard (to be used as a stand) for a movie with all the features of present characteristics of a top laboratory such as 4 to 8 GB memory and a 500 GB hard drive (perhaps as part of the screen or connected to / through the keyboard, if it is used as a docking station)?

    It seems with all the technology of the tablet on the market that Microsoft or somebody would do something like that now.  Can someone help me? Thank you

    -Scott M

    PS: My wife has an ASUS transformer where the screen detaches from the keyboard, so it can be used in the form of tablets.  When it is attached to the keyboard, the keyboard acts as a stand to sit on the counter for watching movies.  And then the keyboard and the screen can fold them together, so when it is closed there is a stand-alone case. This, however, runs the Android operating system.  Basically, I want this same design (for the potability in a Briefcase), but with it running Microsoft Windows so it can be used as any other labtop.  It the keyboard could have a number pad are associated with, that would be a bonus.

    Hi pr-e-s,.

    You can check with asus.

  • Pavilion dv7-6163us windows 7 64-bit, the screen brightness will not adjust

    I reinstalled the latest graphics driver, the latest version of the BIOS and I still cannot adjust the brightness of the screens (screen).

    The indicator appears but is grey.

    Thanks for any help, Paul

    Update on the screen brightness controls; went into the BIOS and reset on off action keys.

    Restarted and there was no change.

    I then uninstalled the drivers for the monitor and rebooted and the brightness setting now works again.

    Thank you all, Todd especially for assistance.

    Hello

    It happens after installing the OS from the Toshiba Recovery CD?
    You have installed any additional program?

    I noticed a similar freeze on my laptop. For the most part, it happened because the background process has not closed, and so the laptop could not force the closure downwards. In my case it was an adobe acrobat reader software that could not close.

    I think you should you HDD defragment and use the freeware CCleaner application.
    This program cleans the program errors and corrects registry entries.

    Try it! Maybe it s not a serious problem!

  • Windows jump out of the screen and an external monitor

    I have an external monitor connected to my MacBook Air.  When I turn off the external monitor (MacBook cover is already closed at that time) and return hours later to turn on the monitor, I find most of my windows have been dispersed (jumped) off the screen.  It occurs on multiple applications: terminal, iMail, browser Chrome, Preview, etc...  I usually find the window peeking out of the side of the screen - a small shard of window - and I have to drag it to the center of the screen.  I have to do for almost all windows (again not all windows to do this).  Its very annoying.  Any ideas on what is the cause?

    I am running v10.11.1 El Capitan (B 15, 42) on MacBook Air (13 inch, mid 2013).  External monitor is Dell.

    I forgot to mention.  It happens all of a sudden... eventually after the upgrade to El Capitan?  (but I am not sure).

  • 15 - ax004na: brief ripple effect on the screen - Misty

    Hello

    Initially, noticed that when returning in the Office of my browser, it is a ripple effect very briefly on the screen. It looks like an interference more than anything else that's not office real ripple, its more about the top of the image; foggy lines. I turned off the wireless mouse in case it was there. haven't tried the wifi yet - Im hoping that its not something serious involving the graphics card.

    More noticeable on light background colors even when jumping to a new tab, moving between applications.

    Wonder if theres a problem with the screen or simply a display configuration I can change to try to prevent this.

    New laptop, only a few weeks.

    Graphics card: NVIDIA® GeForce® GTX 950 M (2 GB of dedicated GDDR5 memory)

    Thanks for your help.

    @brutaledilusso

    Welcome to the HP Forums, it's a great place to get help, find answers and advice,
    Thanks for posting your request, I'll be more than happy to help you

    If I understand correctly, the screen is blurred lines and gets an effect of brief training at certain times,

    I recommend that you check whether the same appears on the BIOS screen (restart the computer and press F10 to access BIOS)

    This would confirm if it is a hardware failure or a problem with the graphics card drivers... so we can reinstall and update drivers to resolve the problem.

    If the problem persists on the BIOS as well, please try with another monitor/TV to identify if it's the LCD or the mother/video card failure,

    I would appreciate it if you could try the above steps and let me know so that I can help further.

    Kind regards

  • Windows will not update the screen resolution and the color depth

    Out of the blue today, my Windows XP installation had its color depth and screen resolution back to the lowest setting and whenever I try to update it refuses to put up-to-date.

    I even try to restart my computer and a bubble appears downstairs offering reset the color depth and resolution to my automatically.  When I click, it appears as if he's trying to return to normal, but again once nothing happens - the colors and the screen resolution is still at the lowest setting.

    Can any ideas on how I fix?

    Hello

    Here are some things to try to fix it.

    Change the screen resolution.

    "How the resolution screen on Windows XP"

    http://pcsupport.about.com/od/Videocards/HT/screenres.htm

    You can also right-click on an empty desktop > properties > settings > it the slider bar allows you to increase the resolution > Apply > OK > agree in the next window, etc.

    If that fixed it, have damaged you graphic drivers.

    Access the site on your computer or the manufacturer of the graphics card > look for a driver download Section > search for your model number and operating system > get graphics / video / Chipset Drivers (depending on how it is formulated) > download and install.

    Change the screen resolution.

    You can also try a system restore before all these problems started:

  • Windows blocked to disconnect the screen after trying to stop

    I put in this forum, as the other post was in the wrong forum.
    Windows Vista Home Edition on a HP desktop computer. I try to stop, and the rest of the computer with logging off the screen with the little circle thingy goes round and round. It doesn't go away until I have press and hold the power button for a while then turns off the computer. It will not stop by itself. When I restart it once I get it shut down with the power button, it gives me a screen saying windows was not shut down properly and gives me different choices on how to restart it. I choose start windows normally and windows starts fine, but will not be closed. It gets stuck at logging off the screen. What the heck is wrong?

    I did the boot, but that did not help either. I scanned with Adaware SE, but he found nothing. The computer would leave answering programs as long it has been used. I tried to install the updates for Vista which took forever because he would leave just to install the updates. Finally, after many trials and lots of swearing, I got all the updates that are installed and the HP updates. I installed AVG and it had to scan the computer. He found nothing. It seems that updates could have solved the problem.

    Hi, Mohammad Ali G,.

    (1) since when are you facing this problem?

    (2) remember to make changes?

    (3) what is the complete error message you receive?

    (4) what is the number of brand and model of your computer?

    Step 1: Disconnect all external devices (printers, scanner, USB (universal serial bus) readers, etc...)  Except the keyboard and mouse and then start.

    See the article below


    Windows Vista or Windows 7 unbootable and the Startup Repair tool does not resolve the problem

    You may need to check the documentation that came with the computer to Factory Restore (System Restore) or contact the computer manufacturer.

    Important: It is recommended to make a backup of your data before performing any Installation of Windows.

  • U2715H - Windows automatically resized when the screen turns off then turn it back on

    • Windows 8.1 Pro
    • 1 single monitor connected to the PC
    • native resolution 2650 x 1440 at 60 Hz the value
    • through CDM of the monitor to the RFP the ti EVGA 750 SC (cable Dell)
    • all drivers updated on 28/12/15

    I just bought this monitor and I noticed this strange behavior. Whenever I have turn off the monitor (or it will turn off by itself), if I didn't have a maximized window, all windows (regardless of size) gets automatically resized to fit in the left upper quadrant when the screen turns back on again.  If I had something full screen, this behavior does not occur.

    I find this very annoying. This behavior happened with my previous monitor, which was only 1080 x 1200.

    I was unable to find any setting for the U2715H disable this "feature". This isn't because EasyArrange from Dell. I do not use this feature. And this always happens with Display Manager not installed.

    Is it just a 'feature' of Dell U2715H? Is responsible for Windows? Help, please.

    TIA

    There was no pilot or changes to the hardware of my first post.  BTW, my monitor is a Rev A02.

    A few days after my previous message, another question emerged.  Monitor flash intermittently ON / OFF every few seconds.  I unplugged/replugged the cable CDM - DP and that seems to fix things... until the next day.  This time, I nothing could fix the random rotation power SWITCH of the monitor.  Desperate, I decided to plug an old HDMI cable, I had to hang out.  Flashing problem has been resolved.  Not only this, using HDMI solved my original problem of auto resizing windows.

    The solution to my original problem: use an HDMI cable.  I went to the Dell CDM - DP cable and the problem has been resolved; no more windows resize automatically when the monitor turns off in sleep/towers.  I always get the native resolution at 60 Hz and there is no noticeable disadvantages to the use of the HDMI versus DP interface.  I've been using the HDMI cable for about a week and there is no other issue.

    Just for additional verification, I bought an Accell UltraAV DP - DP 1.2 cable (B142C-007 b-2), one of the few officially approved by VESA (see link below).  Using this cable does NOT my automatic window resizing problem original.  I do not use it long enough to see if they would prevent the random flashing question.

    I still don't know the exact cause of my original question.  I guess it's a driver problem with DisplayPort standard.  But if you do not need DP 1.2 functionality, I suggest that you just use your GPU HDMI output (if she has a).
