Contrast adjusts constantly itself - really annoying

I have recently upgraded to Windows 8 on my laptop serial Windows 7 Vaio S (SVS151190S). This computer has the hybrid common graphic to Vaio Laptops, with a nVidia GeForce GT 640 M THE and Intel HD 4000.

My question is this - whenever the display shows something dark (examples: movies, screen, pop up UAC start), after a second the screen allows you to set the contrast. Everything seems ridiculously faded, dark TV shows I watch turn crazy and I don't see anything because the shadows are so dark and icons and graphics that were not changed when the display shows something dark become illegible. It is terrible and I can't seem to find a solution to this.

I disabled all parameters Adaptive brightness that I can find, including the VAIO Control center application and contrast "Adaptive" in the Intel Graphics Control Panel. This problem has occurred in Windows 7, but is CONSTANTLY happening in Windows 8 that's why I'm here. It of really, really annoying and completely ruins the experience. I looked for answers online, but they all seem to be describing a fix for the Adaptive brightness.

If anyone has AN idea of what is happening and how to fix it, any input would be GREATLY appreciated.

Hi William,.

I suggest that you use the graphics card, one at a time and then check the issue. Disable a graphics card and check the issue with another enabled graphics card.

Make sure you have the latest driver of the two graphics cards. You can use the link given here and find NVidea driver.

http://www.nvidia.com/download/index.aspx?lang=en-us

Follow the steps here to turn off the graphics card.

(a) press the Windows key + X.
(b) select the peripheral Manager.
(c) expand display adapter . Right-click and select sand DI.
(d) to restart your computer.

Look for the question. Repeat the same steps for the other graphics card and check once more the question.

Note: it is not necessary that two suitable graphics will be presented under the graphics card. Look under sound, video, and game controller.

Write to us with the status. We will help.

  • The functions of the left and right of my mouse buttons keep swapping without doing me anything, and it's really annoying!

    For some reason any the left and right buttons on my mouse keep turn on their own without me doing anything. Once this happens, I go into the properties of the mouse, apply the default and then that's fine. That lasts anywhere from 3 hours to 3 days.

    Hi there from Hamburg/Germany. Since the last two updates of the CC, Photoshop crashes 95% when I work with masks. This gets really annoying when you know that I have about 120 photos to retouch to a customer. Any ideas what's happening here? Never had this problem before. Now, every time I create a layer mask, or try to work on a Photoshop freezes completely, forcing me to restart and (most of the time unless I have record EACH step) start of a scratch. Which is pretty much annoying... any suggestions?

    I use upstream, that allowed color spaces are CMYK. When I place a RGB file, preflight reports an error (very good). But when I add the Fx (effect) does not forward flight "Bevel and Emboss", report an error, which is really annoying. How can I fix? I like to have 'The transparency blend space' on "Document CMYK" and in the preflight profile "Fusion of transparent space" required: "CMYK".

    Interestingly, if I copy and paste your images into a new doc 2 points scored.

    I think that the solution is to assign the CMYK printer profile in the document. In this case, you no longer control upstream for RGB color, because by default it is converted to CMYK space correct on export or print output.

  • on-screen keyboard automatically appears when you edit Word documents on touchscreens - really annoying!

    Hello, I just write my feelings because I really hope that Windows 8 will succeed, but it is disappointing at some point in terms of user experience. I apologize if my word is a bit harsh (since this is a forum for Microsoft), but I hope to see this problem resolved to do. I just get pissed off and frustrated on a simple function that could greatly improve the user experience, but isn't here.

    It's Windows 8 does not pass to laptop mode (i.e. turn off the on-screen keyboard) automatically when it is docked/connected with the keyboard. This totally screw up the initiative of Windows 8 is a flawless, all around solution.

    It is a serious problem for the 8 touch screen windows convertibles. Although I don't know who to blame, Microsoft or OEM. Microsoft being more responsible on the software side, I think that Microsoft should fix this. It is both a problem of Windows 8 and a problem of office or Microsoft even secretly to optimize the software for their own hardware to compete with manufacturers, which I'll explain below. I have a RT Surface and an Asus enrich your life, so I know clearly how Surface has an advantage on its same family competing software wise. These hybrid computers usually have a keyboard dock. When the keyboard dock is connected, the computer must have the ability to automatically disable the screen keyboard on. The usual scenario is when I work with a Word document on my keyboard dock, I use my hand to select text and insert the cursor (which is the thing to do if you have a touch screen). But unfortunately on hybrid OEM, Word appears the keyboard screen on every time I touch the text box, which not only blocks my view but also shifts my text view (taking into account the space for the touch keyboard). But this does not happen on the Surface! Makes you wonder what game is playing on Microsoft's OEM partners. We can say that it is Asus responsibility to add this feature. But shouldn't Microsoft do this universal of the functionality and benefits the entire ecosystem? Especially in this case MS designs software and they can't be cela an advantage over their own material. It is particularly bad experience on OEM hybrids (seen on ThinkPad tablet 2, Samsung ATIV Smart PC, Asus enrich your life,...). I've seen many users complain about this on the Internet with their computer of tactile hybrid of Windows 8 (you can search this forum for similar complaints). The only available for OEM hybrid solution is to disable services touch keyboard and writing, which is stupid and laborious. PowerPoint has also that annoying problem of pop-up auto keypad. I do not understand how Windows 8 will be successful if Microsoft plays this unfair game to its partners. (I hope not, but MS seem to care)

    It is a problem of Windows 8 (except the Surface) because it does not automatically neutralize on whenever screen keyboard that an external keyboard is plugged. If the computer is still in tablet mode, even if it is converted into a laptop, which is laughable, given that Windows 8 is supposed to pass without fault between two modes. The fact that I have to manually stop the service of keyboard on screen (which requires administrative privileges) to switch the mode is particularly annoying.

    It is a problem of office because it is on the Windows desktop, the only way to trigger the screen keyboard on is to touch the icon in the taskbar keyboard, even if you touch the area such as Notepad or address bar in Explorer text editing. This is logical since people will use the mouse and keyboard to work on traditional workstations. However, the only exception is the office, that triggers the keyboard screen on every time you touch a text edit box. Do not ask me to switch the touch mode and mode mouse in the office - no difference. The keyboard is displayed. When you change a word document and need to go through the pain of imagery seen the keyboard popping up every time when you select a word or insert a cursor!

    It is a problem with Microsoft because Microsoft has an advantage over OEMS in the configuration of their software to give the best user experience. But their own material does not respect promises. I am pleased that OEMS have developed options better, but disappointed about how MS software a secrete advantage on their own material (Surface).

    There may be a solution I don't know. I would be very happy if someone can shed some light on me.

  • My address bar search has changed and it's really annoying.

    Hello.
    Today, my firefox has changed something in the address bar search system.
    Now the first link it provides is for "popular sites" or your partners no idea but it's boring as hell.
    He destroyed all my combinations of site search...
    When I wrote normally shortcuts like 'pwn' 'kol' 'da' for my sites now the first link provided to ask me "want to pwn/kol/da search in google? Dailymotion? »
    No ffs I don't want that. If I wanted to, I would use the search bar.
    I tried to fix it but can't find it in the normal options and won't play with the config of my own.
    Where I can it turn off? I can't stand it.

    You can set browser.urlbar.unifiedcomplete to false to remove the suggestion to visit the location bar page menu drop-down.
    Note that the sound is not really new, but it has now enabled by default in Firefox 43.

    You can open the topic: config page via the address bar.
    You can accept the warning and click on "I'll be careful" to continue.

  • Although I loaded Adobe 13 (SEVERAL TIMES), it says "vulnerable." Really annoying! What can I do for this? Nothing? "

    I have windows7, essential security and all others is ok in my laptop. I keep up to date. Now, the only problem is when I try to check out it's plug-ins to date, all the other plug ins are but Adobe flash is not. He said vulnerable in red color. When proceed now updated, installed fine, but if after I double check if all plug-ins is up-to-date, there are once AGAIN this red sign: "vulnerable". I'm ready to change my browser to another, if this annoying problem seems to be fixed.

    Disregard my last post. I see that you use Firefox 30.0 (Beta) that contains a bug in the Flash plug-in detection.

    Related bug (read the Bugzilla Etiquette before you comment in the bug reports):

    • Bug 1011824 - Plugin check page displays the version of the plugin as vulnerable Flash even if the latest version is installed at Beta30b4, Aurora31.0a2 and Nightly32.0a1
  • Please could prevent you Firefox bringing existing windows more on top of my current Firefox window. It's REALLY annoying.

    Ok. I opened firefox with an initial of the window. I have to open another window separate from Firefox. Then I navigate to (of) some sites in the second window. The first window appears on top of the second window.

    I'm not the only person to have been annoyed by this "feature".

    One of the possible reasons are that the last window used Flash and precedents do not have. History and solutions are in this thread: opening of new windows and Shockwave Flash.

    A few more recent pages on turning off the protected mode feature:

    Flash must offload completely from memory (Firefox restart might help) before it comes into force.

  • Firefox is to remember the passwords that I said not to do so. browser reopens after computer restart and I still can't connect. It's really annoying.

    I'm not stupid. I know how to enable or disable password remembering thing in options, but it simply doesn't. He remembers the passwords and logins from sites that I decide to do not. I can restart my computer and Open firefox and go straight into my email online account. It is very annoying.

    Note that Firefox stores cookies of tabs open as session data in the sessionstore.js file, so if you leave tabs open when you close Firefox then you can always be connected the next time.

    You can set the browser.sessionstore.privacy_level pref 2 (never) or 1 (not HTTPS) on the topic: config page to disable the registration of cookies via session restore.

    The browser.sessionstore.privacy_level_deferred pref is used when you do not reopen last session automatically via "show my windows and tabs from last time" and use the same values.
