Maintenance :: Screen Just Went Dim - Windows Can't Adjust Brightness On Display
Aug 31, 2013
I just reset my PC. I was installing things back onto it (firefox, Spotify etc) and all of the sudden the screen went dim. I went to settings and it says "Windows can't adjust the brightness on this display" . Restarting the computer does nothing.
So, a few days ago the battery of my laptop died and when I charged it and power it up again I found that I can't change the brightness of my screen which I was able to few minutes before. I tried fixing it by going onto control panel>hardware and sound>power option, but it didn't work. It's just stuck. What can I do? Is my laptop broken?
I have a new computer , HP recline 23 . OS is Windows 8.1 . It came out of the box with Windows 8 , so I had MS store update to 8.1. The screen is set very bright , OK for day use but too bright for night use .
My problem is that I can't adjust the screen brightness. After clicking on the charms menu and clicking on settings , the brightness icon is greyed out . It says windows cannot adjust brightness on this computer. I tried the various locations where the brightness slider may be but all the relevant screens show no brightness slider.
I don't know whether win 8 had the brightness control before upgrading to 8.1 ( I mention this because several people complain that after upgrading to 8.1 , they loss brightness control amd regained it by rolling back the driver )
I tried the update driver option but it says my driver is already updated. The roll back option is greyed out ...
BTW the display adapter shows two adapters : Intel 4600 and Gforce GT730 . How do I check which one is being used?
I have a Windows 8.1 Toshiba Satellite L875D-S7332, with a AMD A6-4400M APU processor with integrated graphics. My display adapter, according to device manager, is a AMD Radeon HD 7520G.
Now, my problem is that I'm unable to adjust the screen brightness of my laptop. I haven't made any recent changes, and I noticed this about a week or so ago(I don't typically change my laptop brightness, so this could have been happening for longer). In the mean time, I've tried rolling back my display drivers, with no success, and also updating to the latest driver set, which has also not worked?
Well I've had my laptop for almost 5 months now, however I did break it and got a screen replacement yesterday. Ever since then my screen seems dim. I've altered all the settings (as explained on other threads) but I still can't get to the centre of the problem. I had no trouble altering my brightness before my screen replacement so I do presume that the screen that the shop fitted wasn't the correct one and therefore a cheap option.
I went and bought a new laptop since my old one was starting to die on me and stuff. It's a Samsung ATIV Book 4, and it's really nice. This is the first hick up I've had with it so far, and I noticed it happening today. I noticed my screen was really dim today as I was using it, so naturally, I use the Fn key to turn it up, but nothing happens. Up in the top left of the screen, it shows a little brightness meter going up and down as I turn it up and down, but nothing changes. I went to the power options menu and tried to adjust it there, and alas, nothing happened. I even tried disabling the display driver and restarting it, but that didn't do anything.
the screen on my lenovo ideapad Z500 touch has dimmed and i can't adjust it back. i've tried the all the brightness settings i can find adn even updated the drivers but this hasn't worked,
since I updated to Windows 8.1. My screen is stuck on dim. It's not dim enough to be unusable, but it's dim enough that I wish I could turn the brightness up. If I use the hardkeys on my keyboard to turn it up or down, the bar will go up and down, but the brightness won't change. Same goes for using the settings charm brightness bar and adjusting via control panel. I've tried updating my display and video drivers, and messing around with the battery "power plan" settings, but after all that it still won't change.
I've noticed that whenever I unplug my charger my brightness dims down to a point where I know its on, but I can't use it. Usually I have to put my computer to sleep and turn it back on to get it to fix. Also, the brightness wont adjust in anyway when its on. I've tried the function keys and the setting in the side bar. I have a toshiba laptop running windows 8.1 . I also have recently completely wiped it thinking it was a virus of some sorta with no change.
I just installed the windows 8 pro on my dell inspiron 1564 but there are ceratin problems that im facing, like when I increase or decrease the brightness of my screen my laptop reboots and when I remove the power adapter it reboots
a message comes on the screen saying your laptop ran into some problem and needs to restart
I know that the display driver is the main culprit here but where to get a newer driver?as dell is not upgrading the drivers.
2 month ago i had this problem so i searched for a solution here (get back to the basic display adapter ) and it worked fine and no problem appeared . but now whenever i want to play a game like begone or heroes and generals my cpu usage become 100% and i get 20 fps usually 100 also i cant play i all drivers are updated : and if i want to play games i have to install the latest driver but i cant adjust brightness
I have a Lenovo Flex 14 - win 8.1 (64 bit).I have restored my pc and after the recovery the option to adjust the display brightness has "disappeared". The option is no longer in place in the charms bar or in Power Option and the adjustment keys (F11 and F12) are not working either.
Each time I start the computer is is necessary for me to adjust the screen resolution to cause the screen tiles to appear when clicking "start" on the right side of the screen. What am I not doing? When I open the computer the next time I adjust the screen resolution back to a different setting and the tiles come up.
Also (I'm obviously a newcomer to W. 8), I get a dialogue box each time which refers to to: "RUNDll". Something about an issue with opening something???? I click "OK" and it goes away. Appears every time I start up.
I just yesterday finished my new computer (16Gb RAM, i5-4470k, GTX 770, Win 8.1, etc.) and I just today realized that I cannot change the screen brightness. The button is grayed out and says "Unavailable" which I know cannot be possible.
Now, i have done my research and people say that the fix is to update your drivers through the Device Manager, and I have tried that to no avail. I have tried all possible combinations of "Display Adapters" and "Monitors" drivers. None work. I have been restarting my computer after every change .
One thing that I might add is that a lot of people remedy this problem by reverting their Intel Integrated drives back to an older version, but I do not have an option to change it's drivers. It shows up nowhere in the Device manager.
My eyes are burning as I am typing this and I would even go for a third-party brightness program (if that even exists).
I have: Turned off adaptive brightness, told it to never dim the screen at any time for any reason under any battery plan, and still, right-on-the-dot, at exactly 1 minute, my screen turns off.
I have a Sony VAIO VPCS11X9E and my screen brightness is at the lowest setting for some reason. Also, my FN keys for the brightness setting won't work. Any means of changing the brightness does not work, this does include the brightness bar when you go into settings.
I have tried so many driver installs, checked for any missing drivers or out of date drivers, but the only one that seems out of date is my Intel HD graphics which I HAVE updated, yet the Intel driver update checker says otherwise.
I have disabled AND enabled (just in case) the adaptive brightness, but it does NOT work.
I did have Windows 7 Ultimate running on before but decided to upgrade to Windows 8. Windows 7 never had any issues with brightness. Also when I load up, even thought I have replaced Windows 7 with Windows 8, it still loads up the dual boot screen asking me which OS I want to boot with. Booting with Windows 7 will blackout a few times then it will take me to the VAIO repair system. Windows 8 obviously takes me to Windows 8.
When the laptop boots up, the large letters or 'VAIO' are bright and normal and sometimes, but not always, when it gets to the dual boot screen, the brightness is normal. However, when this does happen, as soon as I move the mouse or click a button, the brightness immediately goes back down to very dim.
When it loads up into any other system or boot program the brightness is fine. For example when I go into Sony VAIO's recovery center, the brightness is ok. Also, if I boot into something like miniXP or a separate OS on a bootable disk or USB, the brightness is fine as well.
I have tried many driver fixes, but NONE of them work!! I have tried booting up into safe mode and trying to manually install certain drivers because that apparently works, but it does not make any difference at all.
Well, I have installed Windows 8 on my laptop, but was wondering if there is a way to lock the screen brightness.
The reason being is that family members constantly mess with the brightness and sometimes leave it at 100% when using the battery. I basically want to extend the life of the battery if it is possible by disabling or locking the screen brightness at a certain level.
I have gone into the control panel and tried changing the screen brightness but nothing seems to work. I am the system administer so I should be able to set all changes.
When I upgraded to win 8.1 my screen brightness went up and i can't control it. i tried re-installing the graphic drivers but it's not working. Also my battery backup has decreased from 3.5 hrs to 2 hrs only. What do i Do?
I have tried to change my screen brightness for the first time since downloading windows 8.1(about a month ago) and it is stuck a the lowest level. I have used the keys, the settings, and even the "Adjust screen brightness" button after clicking on the battery in bottom right of screen. I looked at my drivers and checked if my "Display adapters" needed to be updated, it didn't.
i have a smal probleem with My new Acer tablet. The brightness of the screen randomly changes. i did some googling and i learned the tablet is able to auto adjust the beightness. I found a sensor on My tablet and did some testing by shining on it with a pocket torch and saw with more light the brightness increased. How i want it off. I Tried switching off the adaptive settings bit it didn' t work..
possible ways to adjust one's screen brightness within windows 8 on a laptop?
for some odd reason the laptop only adjusts the brightness when on the battery and it does that intelligent adjustment crap(tried to find a more polite word....failed).
I have gone into the control panel and tried changing the screen brightness but nothing seems to work. I am the system administer so I should be able to set all changes.
I've only recently noticed this, but the brightness on my Vaio is stuck.
FN+F5/6 does nothing at all.
Changing the slider on both Win+C - Settings - Brightness and also through the Control Panel display options both do nothing either. How to get around this?
I bought Dell 5521 2weeks ago (8gb ram 1tb hdd i5 1.70ghz). Whatever, now, i can't use my FN+F4/F5 keys. I can't control/change my screen brightness. Other Fn keys are normal. I can use them but just i can't use my brightness. What should i do? A person said me that "download the Fn key's driver" but i don't know which driver is.
So I upgraded to Windows 8 today and finally finished all the installations only to find that using a 1920x1080 resolution means that the display is too big for my screen (a 32" Samsung full HD TV). The screen is cropped by about a half a CM all the way around. I had to revert to a 1776x1000 resolution for the display to fit properly on the screen but would much rather use the highest possible setting but I cannot seem to fix the problem.
I am running 64-bit and have updated all display drivers and completed windows updates. My GPU is an ATI Radeon HD 5800 series.
I have a HP envy m6 notebook and when im viewing websites the brightness will keep randomly changing. Why is this and how do I stop it? I've gone into the settings and turned off the 'enable adaptive brightness' but it still seems to keep happening.
I have Lenovo G580 running 8.1 with intel HD4000 and Nvidia Geforce 610 & Intel CoreI5 3210 2.5GHZ 3rd generation the problem occurs after few days from updating the Intel video card which is simply i can't change the screen brightness whether using the [function+uparrow ] or control panel, it works well when i roll back the driver so am I stuck with the old driver which i can't update or what?
