Can't Properly Adjust Screen Brightness
Dec 29, 2011
So here is my problem. I have an Acer Aspire 4540 laptop that I recently repaired after laying in my closet with a broken display for some time. So I took it to a repair center and got my new 14' LED display installed. Everything on my laptop is working fine, even my screen is working fine. The only issue I've noticed is that when I try to increase or decrease my screen brightness it cycles between the max and min settings rather than dimming or brightening respectively.
Now, I know I've had this issue before but I can't remember if it was already like this before the screen broke. I have tried rolling back, uninstalling and reinstalling my drivers several times yet the issue is still there.
Im running on Windows 7 Ultimate x86 and my graphics card is an ATI Radeon HD4200.
I know this is a small issue but I need to fix it since I spend a lot of time in front of my laptop.

But in the last couple months, once in a blue moon I couldn't change my screen brightness, and now in the last couple days it's gotten a whole lot worse. Usually, I can't change brightness either via my 'fn -/+' hotkeys or via the actual brightness slider in the power panel. A full reboot or simple hibernation then reboot both let me change brightness again. But the last couple days, restarting the computer just puts the brightness on either fully dimmed or fully bright, and I still can't change it.
This is an HP G60 laptop, and I've had windows seven for a year on it. Like I said above it only started a couple months ago then got worse this week, and what I've found on google so far was all for newly-updated-to-seven issues. My drivers all seem to be up to date according to the windows update driver function.

I am using a hp w2207h. I want a software method that easily allows me to adjust the brightness. Currently I have to go through the monitors menu using the physical buttons on the monitor.

im not the best when it comes to knowledge of computers and what not but i'm completely stumped and so is everyone else on the web, it seems. cant find a solution to this for nothing. i also did a search here on screen brightness problems and didnt find anything specific to my problem..basically i just installed windows home 7 ultimate on my hp dv5t after previously having vista on it and i cant find how to adjust the screen brightness.i've googled it and others have had the same problems but i cant find how to fix it. my fn shortcut doesnt work, and when i go to power options and all that, theres no slider or even option to adjust brightness. ive seen where it's supposed to be on windows 7 via Internet videos but it's not there. anyone know what to do, or has anyone heard of this??

I am currently running Windows 7 RC1 and have noticed a behavioral change from XP which I would love to change.
In the NVIDIA control panel, there are 2 sets of settings for brightness:
1) Desktop color settings
2) Video color settings
In Windows XP, these would be completely independent. Thus for example, I could have my desktop dark while the videos could be bright and vivid.
Thus in XP:
Desktop Brightness = Desktop color settings
Video Brightness = Video color settings
In Windows 7, the OS only behaves this way when using Aero Basic. If I'm using the full Aero interface, I get the following behavior:
Desktop Brightness = Desktop color settings
Video Brightness = Desktop color settings + Video color settings
I would really love to have these control act independently on the full Aero interface. Is this possible? NVIDIA settings can obviously still distinguish the video because the video color settings still only apply to video, so I'm not sure why it behaves this way.

well i downloaded Windows 7 and now everything is HUGE. It says the size of my monitor does not meet the requirements to run over 600 resolution. however, i have a monitor well capable of running that.
I have a dell 2300 and the only drivers i can find are for xp on their site. I have been told maybe the graphics card is not strong enough, however, it is only 4 years old. Is it that big of a deal.
I need some help. I am not currently at my computer but i will update with system stats. when i get back.

On my old dell inspiron 8600, after I installed Windows 7 ultimate and update the video driver, I can adjust the highest screen resolution to 1920 x 1200.
but everytime when I restart the laptop, it will go back to 1280 x 1024
I will need to manually adjust that back.
Does anyone know how to fix that problem?
My laptop is using NVIDIA Geforce FX Go5200 card.

Is there an util where I can make the fn key always "pressed" so I don't have to press it when I want to e.g. change the brightness of the screen? My laptop is a Presario CQ70.

On my monitor it seems like everything is too bright, as in places that should be pitch black are a bit too light. For example: on my iPod, even with full brightness settings everything looks normal, but on my PC's monitor it just doesn't look right.I calibrated color and setting gamma way low really helped, but my contrast is set to full, and my brightness is 75.The strange thing: when I ran Crysis 1, it fixed the monitor color! So I know the darn thing is capable, I just don't know how to.When I closed down Crysis it went back to normal.

I have a problem with the screen brightness constantly dimming itself...it doesn`t matter which power setting I try or which route I go down...whenever re-setting,the tab just moves itself back down to the lowest setting...sometimes it stays bright for around an hour and then once again will revert. I have installed a new hard drive and so this is a new installation of windows 7 32 bit...but prior to this new hard drive I had the same problem.

Yesterday I noticed while I was playing Counter Strike, that the colors changed so did the brightness. I thought it was only the game, but I went on the internet and it was brighter than it was before.

I just bought a new Dell N311z I've noticed that when the brightness of my screen is anywhere between maximum and minimum it automatically decreases or increases on will, without me doing anything.
I've also noticed that when the background on the LCD is of a darker colour the brightness decreases and when it's a lighter background the brightness increases itself.
I've tried everything from disabling the ambient light sensor to calling up Dell customer care and after having spent 3 hours on doing what they made me do it still hasn't fixed my problem. I reset the laptop to the factory settings, i reinstalled all the drivers as well.
I have a Dell N311z. Windows 7 Home Premium 64bit.

I installed Windows 7 this week on my notebook Dell XPS M1710.
Everything is good working, except one thing :
When I close the screen, so the notebook go hibernating, and then I reopen it, the notebook leave the hibernating mode, and here the screen goes dark, the brightness is very low, despite the brightness setting is at max. The only solution is to reboot the notebook.
So now I can't use hibernating mode, I have to always shutdown the notebook.
Does anybody have the same problem ?

I just formatted my entire laptop (Samsung RV511) due to a bug that was in the system my antivirus could not detect or the help of system restore would not get rid of either. My previous 2 laptops came with recovery discs but the samsung had only come with the windows 7. I had installed Windows 7 and after doing so, checked everything out. I realized that Samsung has many specific programs and drivers that come with their computers and in the process of formatting, I had deleted everything. My computer is unable to connect to the Internet and I can't even change the brightness of the screen anymore.

I have a duel boot desk top computer. Windows Xp x 32 and Windows 7 x 64. I modified my server load screen and wanted to check it so I hit the print screen key and pasted it to paint and all I get is a back screen instead of the load screen image. Then I took a image of my desk top and the image is fine. Did the same thing on windows xp and everything is fine,the load screen image and the desk are image are coming out just the way there suppose to. Is there a setting that I'm missing on windows 7 that could be causing my problem.

When i am playing a fullscreen game that i cant run at 1920x1080p (my native screen resolution) I turn it to 1280x720p but it makes the picture too wide and really big annoying black borders at the top and bottom. And by "too wide' i mean most of the gui is forced off the screen. I want to know how i can make it fill the screen. I assume that this is even possible because my console makes the picture fit the screen( on the same moniter) at lower resolutions such as 1280x720p.

I have a Philips 220VW 22" 16x10 monitor and till a year ago I had a similar 22" 16x10 Philips monitor(had to replace it since I had some problems with it). After using Windows XP for quite some time I decided to give Windows Vista a try (that was back in 2007). However, every time I boot up or restart Windows, when reaching Windows Vista boot screen (the one with the green blocks, not the log in screen), I had to wait about 10 seconds while the monitor was trying to center the Windows logo without luck since the logo ended up somewhere in the low right corner of the screen.
Unfortunately, this happens on Windows 7. I contacted Philips and they claimed that this is not a hardware issue but a software issue since everything else was fine. I was told that Windows 7 does not have a proper scaled loading screen for this monitor???. This also happens when, by any chance, I end up with the Windows fail options screen (the one with last goon known configuration, normal boot etc - don't know how it is called ). I know I don't spend too much time staring at the loading screen but is there any way to fix this?

I have a
Lenovo Laptop Thinkpad Edge E520
8GB RAM
Intel CPU B960
Pentium Processor 2.2GHZ
Recently when I have powered up my laptop it occasionally doesn't load properly, the screen stays black. You can hear the laptop working fine but you cannot see anything. This happens once or twice a week, I usually hold on the power button for 5 seconds, then reboot and it resumes my hibernate settings as usual. Could this be because I always hibernate my laptop?
