Hello:

You have installed the graphics drivers?

To install the graphics drivers in your model, you need to:

1. install the Intel chipset installation and restart utility.  The second listed file is the auto install file.

https://Downloadcenter.Intel.com/download/20775/Intel-chipset-device-software-INF-Update-utility-

2. install the Intel HD graphics driver and restart. The first file listed is the automatic installation file.

https://Downloadcenter.Intel.com/download/24870/Intel-IRIS-and-HD-graphics-driver-for-Windows-7-8-8-1-64-bit

3. install the Nvidia HD graphic driver and restart.

File name: sp66512.exe

If the graphics drivers are not installed, the brightness of the screen is blocked to the maximum, you can not change the resolution of the screen, or put the PC in "sleep".

  • Photos of airPlay on Apple TV look too bright

    Folds in salvation,

    While all the video content crosses very well on my screen of 4 K TV, photos are coming across too bright, no matter what camera I use as a source (iMac, iPhone and iPad). No recommendation for this problem?

    Thank you.

    You have not specified what generation TV you use, but it is not really important. I'm not aware of any solution that allows for "by app" brightness adjustment. The only source that you do not list iCloud photo library, but I doubt it would make a difference.

    You might just find an acceptable compromise, or use one of the TV set pre-series (movies, sports, etc.) to switch to displaying photos.

  • Adjust the brightness of the keyboard of the computer instead of the keyboard?

    Yesterday, I spilled some coffee on my keyboard and the computer works well, but my keyboard does not work.  I bought a wireless keyboard to use and it works perfectly, except that the keyboard of my laptop backlight is always on.  I can't figure out how to turn off without using the f5 and f6, keys that don't work on the laptop, so how can I disable this light without using the keyboard?  F5 and f6 don't work on the original keyboard at all, and on the outside, they do not work to adjust the brightness.

    Try this:

    Go to system-> keyboard Preferences, and in the keyboard tab, disable(uncheck) automatically "illuminate the keyboard in the dark.

  • How to stop or reduce the brightness of the display on a calendar

    Hi people,

    I have a Pro iPad with iOS 9.3.3 which I intend to use for a limit on a store.

    The store is open from 10:00 to 21:00, if of course, I would like to set up the iPad to go to sleep, turn off screen or totally to reduce brightness from 21:00 until 10:00, is it possible?

    I tried the Night Shift option with "Warmer", but it is not really dark.

    Thoughts?

    Thank you

    Hello... You can do this with the standard IOS. The only thing you can not put any password so that customers can open a release at any time and set the brightness to AUTO.

  • 36 Firefox changes on ALL too bright and saturated colors.

    Now I have 28, 33 and 36. All previous versions were the same and more accurate color. But, 36 makes all too bright and saturated. All pages. Even the icons of bookmark. Everything.

    Something has changed. Could have changed at 34 or 35, I skipped those. but here in 36 is definitely a problem.

    There is a new parameter, that I missed?

    Appreciate your answers. It's hard to see.

    You can attach a screenshot?

    • Use a type of compressed as PNG or JPG image to save the screenshot
    • Make sure you do not exceed the maximum size of 1 MB

    This may be due to a problem with the profile for your monitor screen colors or color profiles embedded in images.
    Try disabling color management to test whether it is caused by a problem with color management.
    You can set the pref gfx.color_management.mode to 0 on the topic: configuration page to disable color management.
    You have to close and restart Firefox for the changes to take effect.

  • Reduce consumption of battery motion and automatic brightness

    Hi, I would like to know some things.

    First: activation reduce motion put on iPhone save the battery life since perspective wallpapers are being turned off when the low power Mode is on?

    Second: Automatic Rotation of the brightness to the wide and holding the brightness at Midway to consume less energy than to have automatic brightness, allowing the iPhone to constantly check our environment and adjust the brightness?

    Thank you!

    To the first question, while I can't tell you with certainty, yes reducing motion should keep a battery life.

    To the second question, it depends. If automatic brightness is to keep the phone on a higher setting to half way then it would be. If A - B fits between a minimum and a high level, then probably not. I keep A - B on all the time and I have no problem with the battery life, but if I'm outside it would be a trade off between being able to read the screen and save battery.

  • iMac darkens when in display mode using target (TDM) and the lack of brightness slider!

    Hi all

    I use a MacBook Pro (13 "to end 2011) and iMac (27", by the end of 2012). Both are up to date, running El Capitan 10.11.5. They are connected with a thunderbolt cable in order to use the iMac as a second screen (TDM).

    Now, when I press CMD + F2 to the iMac, iMac gets used as second screen as expected, but it goes really dark! He's not black, you can still see the desktop but on a sunny day, it's really hard to see anything. Now, it's pretty embarrassing, but the second part of the question makes it a pain in the *. When the iMac is dark, I always go to the system preferences and open the settings for the display. I can see a window with the parameters for the iMac, but there is no cursor for the brightness! There is no way to make it brighter!

    The only solution is to disable the target (CMD + F2) just display mode to enable it again after a few seconds. Sometimes I have to activate the TDM twice but sometimes it takes 4 or 5 loops toggle just to see the brightness slider!

    Here is a screenshot of the settings without the cursor window

    And that's what it looks like after a few loops, and then I can adjust the brightness.

    Any ideas why this happens? Any advice on a possible solution? Why - what is darkening the iMac? Why is the cursor missing?

    Best,

    Stephan

    There are other topics on this issue, like the one below. One of the workarounds suggested is to use shades free app: http://www.charcoaldesign.co.uk/shades

  • Iwatch brightness changes automatically

    The problem I have is that I can adjust the brightness of the brightness using my iPhone or the iwatch, and to keep the battery turned it down, but the Watch has a tendency to change the brightness for a setting much brighter I put randomly.

    Is - it so the watch should work, or I do something wrong or is this a problem with the Iwatch?

    Hi TheWeav, the article you mentioned is for the new phones of filed. Is your question about one of those or Firefox on your Windows XP system?

    Versions of Firefox for desktop computers do not have a brightness adjustment. You can adjust the brightness of your display using the global setting for Windows, which may include some special on your keyboard function keys or a Windows Control Panel.

    If you want only to adjust the brightness of the pages in Firefox - to moderate the white backgrounds, for example - you could try an add-on.
