Main Monitor Brightness Turned Down For No Reason
May 30, 2011
I have two monitors on my system (win 7) and from time to time the main monitor gets turned down in brightness. The other monitor is just find but something ( a virus, malware or program) is turning the brightness down for no reason. I have run malware and virus protection and found nothing.. Sometime is will be in the middle of a session and other times it will be on boot. It's not the monitor I'm sure (turning it on and off does not work) and it's always the same monitor that is effected.

I have a three monitor set up. Whenever I open up a browser, either internet explorer or google chrome on monitors 2 and 3, after a few seconds it automatically drags my browser into my main monitor(monitor 1, where my start button and status bar is located)

I have a setup with 6 monitors. Today my main monitor broke and I couldn't find a way to shut the PC down since I couldn't access the main desktop to get to the Start menu.Is there a way to change which monitor is the main monitor without having access to the current main monitor?

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.

I just accidentally changed my settings on my grapics card so that I can no longer see my desktop on the monitor connected to my HTPC. My HTPC has a monitor attached to it and it also has an HDMI out from the graphics card going to an LED TV in another room. I accidentally switched it so that the desktop can only be seen on the other TV in the other room.
All I can see on the monitor is the blank Windows 7 logo (no desktop icons) and I cannot navigate back to my AMD control page to undo this. I tried rebooting but this does not work. This is an issue as I don't have a bluetooth keyboard/mouse that I can use in the other room to control the desktop. How do I reset this? I am using a AMD HD 6750 graphics card.

CRT 21/750 Formac (SonyGDM) / point of view 8500GT / Windows 7-64
xfx 680i LT / 4 gB ram / Q6600 / latest XFX BIOS
(My first PCIExpress card - be gentle ;-) Here's what I've been doing
for what seems like the best part of two days -
1 Boot in safe mode, disable 8500. Reboot.
2 Drivesweeper'd nVidia display drivers in safe mode. Reboot.
3 Restart in safe mode to verify drivers gone, but 7 just goes ahead
and renistalls 195.62 anyway (A moderator on the nVidia boards says
that these latest drivers should NOT be installed in safe mode.) & asks
for a reboot.
4 Reboot as instructed, then screen blanks after entering password;
pretty much what I've gotten from day 1.
> Now, just today I tried something I saw somewhere here (?) where
A I reboot the PC (after 1,2,3 above) with my monitor OFF
B Enter my password 'blind'
C I finally get to a proper desktop which appears to be using the
correct drivers (Refresh rate looks much better) but I can't verify
graphics card changes, as this causes a blank screen again.
Monitor is the only device plugged into the GF card.
Where have I screwed up?

My monitor is an HP S2031. The computer is a Compac Presario CQ5814 PC, Processor is an AMD Dual Core Processor E-350. Running Windows 7 Home Premium 64 Bit. Bought in 2011. Running Chrome Browser most of the time. Shockwave crashes on me quite often but seems to "fix" itself. This had happened shortly before the monitor turned red. I had turned off the computer and when it was turned back on the screen was red. I restarted it a couple of times and it finally returned to normal.

When I switch on the computer, on the monitor, I just see the start window and green dots running, then the monitor screen went black and say 'no signal', I can't even switch off the computer unless holding the switch button for a while.

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.

i recently got an update from microsoft on win 7, and immediately after it had finished updating i had no sound in any application (aim, skype, chrome, firefox, Internet, etc.). this has happened before, and i ran microsoft's sound problems wizard and it always said that an option had been clicked off and that it had restored it.this time when i ran the wizard it says it detects no problems. i am sure it is the software, as it happens a lot with ms updates. will downloadi can't go back to a previous configuration, i don't have one to go to

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?

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.

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?

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 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.

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 have a dell latitude d620 and one day the up and left keys magically stopped working.. later on I had the brightest idea to see whats the lowest level of brightness possible, now I'm pretty much screwed because I cannot get the brightness back up to normal (which is a pain in the rear end) using the FN+UP combination.

I have a Elitebook HP 8530p, and it has a issue with the screen brightness. When put 100% (energy properties are at : high profile) the screen dims, but the % remains 100, however when manually setting to a lower then to max again the screen is bright (as it should be) This happens while i'm activly using the computer. (mouse/ keyboard interaction)I disabled every possible auto-dim feature I found. This happens at random moments but every 1-5 min it happens.
