Cant change win 8.1 screen brightness level

Hi I just upgraded to Win 8.1 from windows 8 pro adn my screen brightness is stuck at the absolte highest.I can only use my pc for a very short while before my eyes start to strain . Any Ideas?
I use a HP envy 14 1195ea Beatsedition. 

The driver to control your brightness on Windows 8.1 does not exist yet, as the previous link demonstrates. For now, the only solution I can offer is to do a System Restore, which will eliminate 8.1, and leave you with functional drivers. You can always re-update 8.1 at any time. Here is information on how to do a System Restore: http://windows.microsoft.com/en-CA/windows7/produc​ts/features/system-restore

  • Feature Change: Remove useless adjust screen brightness button.

    Remove useless button for screen brightness.
    both buttons serve same function.

    Oh - that explains it better.
    You do know that not every computer using Windows 10 has a key available to adjust screen brightness though, right?  Or, as in the case of the Surface, if you don't have a keyboard, the only way to adjust the brightness is only the software one? 
    For you it might not make sense, but include ~1 billion more people, and I think they should just leave both. 

  • Lenovo S400 screen brightness darker on Win 7?

    So I recently bought a Lenovo S400 that came with Windows 8 for someone.  However, he didn't like Windows 8 so I installed Windows 7 on it.  After installing all the driver, the screen for some reason got darker.  It seems like the lowerst the screen brightness can go and the hightest the screen brightness can go got lowered.  I thought it may have been a driver issues so I uninstalled and reinstalled all of the driver without any luck.  So I just formmated the computer again but still no luck.
    Does anybody have any solutions for this?

    ***UPDATE***
    Ok so the problem is confirmed! As soon as I restored Win 8, the screen brightness was set at 65%, I was quickly able to turn it up to 100% and the screen is as bright as ever. So it is now definitely not a hardware issue but an issue with Win 7 drivers Lenovo provides.
    Now, I will try getting all the drivers off the hidden partition and try restoring my Win 7 back and trying that Win 8 driver. If that works, I will upload the Win 8 driver for everyone and post a link.
    But, I definitely discovered the cause. It's drivers!
    PS
    In fact, I will post the driver if I find it now, so you guys can try it out before I do the Win 7 restore again.
    Hmm, the only problem now is I can't seem to see the drive with the drivers on it. I know I had it before, but I can't see it now, I recreated all the partitions Lenovo came with, keeping exact sizes, but I can't seem to assign a letter to any of them through standard disk management app.
    Ok tried viewing the hidden partitions.... I just remembered that I was stupid and didn't backup the D drive, which is where the regular OneKey Backups go and the drivers were in that folder as well.....
    So if anyone has Win 8, please upload it somewhere, preferably dropbox or mediafire, so I can test it.
    Because it'll be a long time before we get it from Lenovo and I really hate Win 8!

  • Spasming brightness level

    Every now and then, this thing happens on my W701ds, where I open the lid (I have it set so that it does nothing on closing the lid...so it's not coming out of sleep or anything) and the screen brightness level starts twitching back and forth between two settings (like between 10 and 11). The only way to get it to stop, is to hold down one of the brightness Fn keys to push the level all the way to the min or max.
    Has anyone else seen this? I searched and couldn't find anything, but maybe it's been described differently. It's fairly spectacular, so I have to imagine someone else has posted about it.
    I'm not even sure what to target as being responsible for this. It does seem like it normally adjusts its brightness to the abient light level, I assume using the same sensor as for color calibration. Is it HueyPro that does this or some other system component?
    This may be unrelated, but occasionally when I open the lid it comes up with an odd colored cast to it for a second or so, as if it is adjusting the colors, though I didn't think that was supposed to be happening automatically.
    If anyone can give me any clues about how this stuff works / is supposed to work, I'd appreciate it.
    Thanks,
    Eric

    This also happens without lifting the lid...if the monitor gets shutoff to save power if I have not touched it in a little while, it sometimes goes into spasm mode when I move the mouse and it turns the monitor back on. Which brings me to theorize a cause:
    I suspect that the power manager which adjust the brightness level according to your power scheme (such as to turn the monitor on or off or adjust brightness differently for powered vs battery) ends up "fighting" with the component (HueyPro, I believe) that is changing the brightness level for room light compensation. I think it happens when the room light level has changed between when powermanager turned off the monitor, and when it turned it back on.
    If so, its not clear which of these components is at fault or if it is something at a deeper system level that should be coordinating between them.

  • Adjust Screen Brightness in Energy Saver modes?

    Can I set a custom screen brightness level in both Battery and Power Adapter modes? The Mac seems to always default to a certain level, but can this be changed?

    Nope - on my wife's MB (i.e. 13" MacBook, unibody/late 2008), there's no 'custom setting' or 'Details' when clicking on the menu bar battery icon. There is a shortcut to the Energy Saver preference pane, but no option to control brightness in that preference pane other than the checkbox I mentioned above. You can set timers for display sleep, etc., of course.
    So, what I see on my MBP, what I see on my wife's MB, and what you're seeing on your MBP seem to be the same. If you have access to a MacBook, check again - if you find the setting your thinking of, post a screenshot...

  • Q10 screen brightness is very dim in dark environmen​t

    In a dark environment the screen dims so much that reading text on a white background is terrible.  Is there a going to be an update to stop the auto brightness feature?

    You're not the only one. This is a severe issue that will hamper sales for sure. The BlackBerry Q10's maximum brightness is the DIMMEST out of every other phone on the market today.
    IN FACT, the maximum brightness on the Q10 is 22% the maximum brightness of the iPhone 5 (in lumens): http://www.computerbase.de/artikel/handys/2013/bla​ckberry-q10-im-test/3/
    BlackBerry is already getting a ton of flak for this issue, as many, MANY users are furious. See this comparison with the Bold 9930: http://forums.crackberry.com/blackberry-q10-f272/v​ery-dull-screen-brightness-level-q10-808915/index5​...
    There is also a few news articles circulating: http://www.newstimeafrica.com/archives/31992
    I will be returning my BlackBerry Q10 tomorrow to Verizon Wireless for a full refund. Back to the Bold 9930 until a PROFESSIONAL product is released. I don't even mind straying away from BlackBerry at this point. Not making brightness control available to the consumer is a violation of trust.

  • New iMac brightness level keeps changing (auto adjust NOT checked)

    Just got a new 27 inch iMac and keep on having to change the brightness level back to the brightness I prefer.
    I do not have auto adjust checked, I put the brightness slider up to the level I like and after a while the brightness dims to what seems like the default level as its always down to the same spot on the slider...what gives? i just want it to stay where I want it...
    Help.

    I have same problem, of autobrightness being unchecked and my brightness going from full to about 3/4 bright
    all by itself. I had that problem, then flickering of my screen also was taking place. I didn't bring my unit into Apple
    because this autobrightness thing plus flickering would not happen on command,, and I wouldn't be able to show them properly. Well , finally my left side of the screen dimmed,, and that was the go ahead to bring it in to them
    to show the left side of screen. I also told them about the flickering,, and the autobrightness, which I figured played a role into the final left side dimming. They replaced the backlight and the display LCD on warranty.
    I have had it for about 5 days. The screen is equally lit (as should be), however, I discovered that my same old
    problem of autobrightness, is slipping back to 3/4.  So most of you have autobrightness problem in a sort of different way. I set mine to "torch" because my downstairs bedroom is dim (with one overhead light), but sometimes, just plain dark,, so I want to sometimes keep it at torch,, however, it still slips back. You would
    almost think that if my surronding was dim or dark, that it would stay on torch if the autobrightness was really working properly. Go figure. I just tried SMC a short while ago,, I had tried, before my repair doing PRAM and the other one (I think VRAM).  I also will unhook my second monitor to see if that is having an impact on things.
    Do any of you in this post have a second monitor attached,, and have you tried unhooking it to see if the problem
    is resolved?

  • Brightness levels change while using Apple TV

    The brightness levels change on my TV screen every few minutes while I'm watching my Apple TV. It happens with "Internet" sources (like Netflix and Vimeo) and "Computer" sources like iPhoto for sure. Maybe the other sources as well. Any clues?

    Welcome to the Apple Community.
    Check that the HDMI cable is correctly seated at both ends.
    Try disconnecting the cable and connecting it again.
    Try another HDMI cable.
    Try the Apple TV with another TV

  • Cant install win.8.1 on a older samsung NetBook w. 11" screen

    when going to windows store for a free upgrade it gives error message" screen resolution to low."
    and I cant take installation further then it stops and I cant change screen resolution  of course then its low.  The netbook its a 11" 

    Hi,
    According to your description, I would suggest you check the video card driver, please make sure to install the latest version, you can manually find the latest driver from the manufacture website, then change the resloution again.
    Or you can contact the vender, check whether this model of PC fully supports Windows 8.1, it's always recommended to run Upgrade Assistant before you upgrade to Windows 8.1

  • [FIXED] after upgrade ACPI can no longer change my screen brightness

    EDIT: never mind, it seems to of gone away now...i have no idea what happened, it stopped working randomly then started working just as randomly.....whatever...
    Just yesterday i was using my laptop with arch linux with the brightness turned all the way down, as of course it saves battery
    but now i turn it on today and the screen is at maximum brightness, and every time i try to change it it just says (in kernel.log) :
    Sep  8 10:28:46 Polygon kernel: ACPI: Failed to switch the brightness
    Sep  8 10:28:46 Polygon kernel: ACPI: Failed to switch the brightness
    so...what got upgraded that broke this? does anyone else have this problem?
    here is the past few days of my pacman.log: (it has some entries for kernel-my, a custom compiled kernel, but i get no screen brightness control on my custom compiled kernel, or the default arch one)

    Do you happen to know what package broke this? I had this issue a couple weeks ago, and just recently it reappeared.

    I am unable to change my screen brightness using the fn+F2/fn+F3 keys. I understand that it can still be adjusted differently but I want this way to work. Also whenever I change my volume using the fn+F7/fn+F8/fn+F9 keys, the little on-screen display doesn't pop-up any more. I would like to fix this and any help would be greatly appreciated.

  • Strobing Screen on MBA (all brightness levels)

    I seem to have gotten a Mac with all of the above.
    Losing WiFi connection, and not being able to turn WiFi back on.
    Screen randomly going black after sleep
    And now the new addition to the list:
    Screen flickering at approx 25 frames per second on all brightness levels on both battery and. Restarting randomly fixes the problem, randomly does nothing. I have reset the SMC / PRAM. Seems this otherwise beautiful baby is going back .
    Add yourself to the thread if you're experiencing the strobing effect.

    I have the same strobbing or pulsing back light problem. I really regret getting this new MBA. The 2010 model had none of these issues. My laptop doesn't wake from sleep randomly, when it does it takes forever to actually resume and now this black screen with the flashing backlight. Apple needs to address all these issues ASAP or I'm going to ask to return this thing for a refund!
