Screen Brightness Constantly Dimming
Nov 16, 2012
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.

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.

alright so just recently my screen has been dimming when i stream videos(south park studios, Internet). i have my laptop screen set to dim after three minutes of being inactive, but i thought watching videos was an active process. after five minutes my laptop screen turns off, which is how i have it set for inactive use.
i'm using an hp dv7t laptop with windows 7 ultimate 64-bit installed.
maybe this isn't a problem with windows, but a problem with the browser i am using? i'm using the latest version of firefox.

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.

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.

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.

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.

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.

My PC's display just went off while I was surfing the net...first I thought it was the screen, so I plugged in another screen, windows booted and same happened after a few minutes after startup...screen just goes off...Now to my knowledge it can be 2 things:
1. graphics card
2. RAM. Notes: I do not get any beep errors...
I would like to know, what are the best software available for testing RAM issues? Also, I am using AMI BIOS(american megatrends v7.4, 2009), how do I do the startup memory diagnostics? I know there is a shortcut for it...
Also, I'm typing on the PC now that is giving me issues, don't know how long until display goes again...

I have a brand new dm3t series laptop. There are two issues that I'm having with the laptop that no one can seem to figure out. I literally had an HP tech remote access my laptop and spend an hour trying to figure out what was wrong.
I have tried system restore, recovery, re installation of drivers and really everything else they've asked me to do. I turn to the forum to see if anyone is can help, thanks much.
1) First issue is very annoying. When I awake my computer from sleep the mouse is very sluggish and doesn't hardly respond to the track pad. Furthermore, the mouse is a magnify glass and when I do try to move the mouse via track pad it just zooms in and out. Oddly enough, after a few minutes of sitting there the mouse starts to work again. It's almost like the mouse has to warm up. It is very frustrating.
2) Second issue is the display on battery power. When on battery power the screen CONSTANTLY is dimming and brightening itself. For instance as I'm typing this thread the screen is brightening and dimming for no apparant reason. I'm not sure why and i'm sure it is wasting my battery. I've tried all sorts of power management tips/ticks and still nothing.
Any help would be appreciated, should I just return it? What can I do?

Every day or two, Windows 7 is REVERSE dimming on me and I can only fix it with a reboot.What I mean is, suddenly when the AC Adapter is PLUGGED IN, the screen will be DIM (Even though control panel shows it as max brightness on the slider). But then once I UNPLUG the adapter, the screen is bright like its supposed to be..For the life of me I can't figure it out, but it's driving me to the point of insanity because I keep having to reboot so often.

I'm having some trouble with my home built computer, with Windows 7 home premium OS. When my computer reaches the the windows 7 logo screen, after a couple seconds a blue screen flashes for about half a second and then my computer resets constantly. I have had issues with starting up the computer in the past but now it's really bad. I tryed to do a system restore but an error comes up with the numbers 0x80070057 on it. I would give you the blue screen number buts it's litterally impossible to see.I have tryed unplugging all usb devices.Unplugging cd drive, extra hard drivesTaking out extra ram (from 8gb to 4gb)I havn't had any problems with my self built computer for about a year until now. It works great, just has trouble starting. I have tryed many basic soultions to try to fix it and nothing worked! I am completely clueless

I understand how to turn down the level of brightness through backlight control but how do I decrease the level even further? The slider in the brightness bar is all the way down (left) yet at nights the light from backlights are too bright.

When using it, after a while (10 or 15 minutes perhaps) in which I haven't touched the keyboard, the brightness is suddenly reduced. Hitting any key, but not moving the mouse, brings the brightness back up again. After a while it does it again, and again seemingly at more frequent intervals. Eventually it comes to the point where even when I press a key the brightness stays low. I then have to right click on the desktop, choose Graphics Properties which brings up the Intel Graphics & Media Control Panel and reset the brightness from 0 to say 50%. It is usually OK after that for some time.There's nothing wrong with the monitor - when using it as an additional monitor with a laptop with Win XP its brightness remains unchanged for hours.

I use Pangobright because the brightness of my Toshiba laptop doesn't go as low as I want it to be, when I'm using the laptop in complete darkness. But Pangobright also doesn't seem to go as low as possible, and when I dim it too low, I can't see a part of the screen unless I'm looking down at the screen. Is there a better screen dimming software?

So I noticed that every time Windows 7 loads and I'm using my battery then plug into my AC adapter the brightness won't get brighter, I have to manually go into power options and drag the little indicator bar. I want it when on the AC adapter to have a full bright screen and when on the battery 50%. Well Windows 7 doesn't want to seem to remember that because after every boot both the battery and ac adapter will have brightness settings at 50%.
This is a Windows 7 problem and I was wondering if anyone has a solution.

I've recently got a new computer laptop with Windows 7 and the first thing I noticed that the screen is much brighter (and maybe more saturated) than my previous laptop (with Windows XP). First I thought it was my laptop, but then I saw an other computer with Windows 7, and the screen there is very bright too. I searched the net and I see that there are more people complaining about the brightness on Windows 7.I understand that I can set the screen brightness, but it seems like a fact that the "default" brightness on Windows 7 is way brighter than on Windows XP. Some people are probably accustomed to this, but to me it's too much. I can decrease the brightness with the laptopl's controls on the keyboard, but I think that's not the way to go - I think I should look at the Windows 7 configuration. I could go to the ATI Catalyst, but is there an other way? Is the Calibration tool the only option?
