Q: Windows 7 screen brightness

Laptop, Tosh R945,Win 7 Home Premium

The computer changes the "on battery" brightness to full periodically. I cannot figure out the common theme to this....

I set it to 70% to save battery

sometime later it is 100% again

nobody uses the computer except me
I am not changing it

I'm not sure but after 25+ years as an RN and at your given age of 81 yrs young and the symptom of "very dim on the right side' of both the mail and the C:\ area I'm wondering if you may have an advanced cataract in the right eye. Just try covering your right eye and viewing the areas you mentioned in your post and let us know. I believe you can see the "Folders" clearly as they are located on the left side of the screen and you use your left eye to view that side.

I have a HP Spectre x360 - 13-4009na  and have just upgraded to Windows 10. The problem is I cannot alter the screen brightness using any of the usual methods. - The fn buttons do not work- There is no brightness control displayed on the Control panel - Power Options- The Calibrate Display Colour method fails with an error while "... preparing to calibrate ..." - "Unspecified error". So my display is set to high brightness and I cannot change it. Please can someone help? Thanks, Paul.

Hey, I never really noticed it before, but today when I was trying to save some battery on my laptop, I was trying to change the brightness down and it wouldn't work. I even tried using the hotkeys, which were also unresponsive to my commands. If anyone knows a fix to this, please tell me. Thanks!

I've installed Windows 7 on my Qosmio G30-140 but I'm having trouble adjusting the brightness settings.
Instead of allowing me to set the slider to any position I want I'm stuck with only 3 steps from which to choose from.
The last one is way to bright and my eyes keep tearing up from having to deal with this insane amount of white, especially on white backgrounds.
The other two are very, very dark.
What's going on? I've installed the correct Nvidia drivers.
Also I can't seem to set the brightness by using the FN keys on my keyboard. They simply produce no result at all.

Help appreciated, I can't work like this.

Thank you!

i just installed Windows 7 Enterprise x64bit today
and i can not adjust the screen brightness
-before i installed the driver pack, it didnt even show this option

and after i installed the driver packs the option is there but its useless
i have put the screen brightness on minimum but the brightness is still maximum and my eyes are about to pop right now

somehow i don't have this problem on the x32bit version.

is there any driver that i have to install or any way to fix this ?

A:Windows 7 Enterprise x64bit [ Cant adjust screen brightness ]

What driver pack? Win7 is a driver-complete OS after you enable Automatically deliver drivers via Windows Update (Step 3) then run all rounds of Impotant and Optional Windows Updates until no more are offered when doing a Check for Updates after reboot.

Any drivers then missing should be imported from the HP Support Downloads webpage for your exact model.

If you have an HP then don't reimport any of the HP bloatware but sometimes a piece of software is required to make the hotkeys function correctly. You'll need to study the software posted for your model to see which is required. If you tell us the exact model and link us to the webpage we can often spot it for you if you need help.

Hopefully you followed the other steps for a perfect Clean Reinstall - Factory OEM Windows 7 because you will get and keep a perfect install to the exact extent you stick with the tools and methods given.

If you forced a bunch of old drivers into an OS which provides its own drivers then you will have problems.

I have a new Toshiba laptop and everytime I reboot the brightness goes to the highest setting

I turn it down using Fn+F6 but then when I restart it goes back to full brightness.

Is there somewhere else I can change this setting?

Also, I've noticed that while I'm browsing and opening new tabs or instances of IE... there comes a point where I can't launch a new window or tab. Clicking on a link does nothing. Right clicking on a link does nothing. Ctrl+N does nothing.

Is this IE 7 specific or a machine issue?

Hi, I observed a problem on my new pc with windows 7.

When I try to adjust the screen brightness, the adjustment slider is always in minimum in Control panel>Hardware and Sound>Power Option, as shown in this picture

but once I go to the "Edit Plan Settings", the slider is in maximum position, as shown in this picture

I can adjust the brightness under the "Edit Plan Settings" but not in the "Power option". Something must be wrong here, does anyone know how to fix this? Many thanks!

A:Problem on screen brightness adjustment(Windows 7 Ultimate 64bit)

Hmmm... That slider doesn't even show on my PC until I edit plan settings.

Is this a laptop? Is your screen dark?

If you can't adjust the slider on the Power Option window it likely isn't doing anything anyway. It might not be anything to worry about if your screen is operating normally. I know of no fix for it, but others might.

A:Screen brightness changes on its own?

Your computer's got an ambient light sensor to detect and automatically adjust screen brightness based on surrounding lighting. You'll have to disable the setting. Lenovo has their own energy management program that has a setting for it, but I'd imagine there's something in the Control Panel (maybe Power Options?) that allows you to turn the setting off.

I've noticed this happen twice. All of a sudden the screen flickered for just a second and the colors on the screen got brighter. By brighter I mean the the actual color changed (ex. my blue taskbar looked grayish). Both times my laptop was plugged in and the second time it happened I simply unplugged the computer and it changed back. After plugging the adapter back in the screen went to plugged in settings, but did not change the colors. The two times were separated by about two weeks.

I'm curious what might be causing this. It's probably just some little bug with a driver but I wanted to know what you guys thought.

Hey guys

I have a very small problem here. I had a recent format to my laptop. Assume now that I am working on the battery. Whenever I plug in the AC, screen brightness increases perfectly. No problem here. Now imagine, I put the laptop to sleep or hibernate and I plug in the AC. Whenever the laptop comes from sleep or hibernate, screen brightness stays dimmed. I need to adjust it manually every time.

Did any of you experienced something similar to this one? I checked other posts but most of them are related with not being able to change the brightness manually. Nothing like my problem.

I appreciate any suggestion

since a reboot fixes it (at least temp.) it is probably not hardware but software. Do you have a backup from before the problem started getting worse?

I like my Toshiba Portege M300 because of compact size, etc. Recently I needed a new hard disk and my repairer loaded W7. I used XP previously and Toshiba do not recommend W7 for this notebook due to age. However, all is working well apart from the screen brightness adjustment. This was previously done by the Fn+F6/F7 hotkeys and there was a driver for this.

In W7 Screen Resolution there is supposed to be a brightness slider but this is not present on my W7 system (I gather that this not an uncommon feature)

How can I adjust the setting sin my notebook to fix a brightness as I am resigned to the fact that the old brightness adjustment will not apply now that I am using W7? Is there a change in the Bios that might help?

A:Screen Resolution Brightness.

I didn't think that the brightness settings of Fn+F6/F7 were affected by the OS but I've been wrong about stuff like that before

In the BIOS, there should be some kind of power or battery settings section that may have some LCD brightness settings that you can try tweaking.

I have looked every post to see if this has been answered before and the solutions but for some reason none of these solutions are available on my windows 8.

i really dont know whats going on here... every option that is on a forum just doesnt seem to exist on my system. My monitor is a samsung 21.5 inch. Please help me because my eyes hurt from the brightness

A:cant adjust screen brightness

Hi, I too have a Samsung Monitor (T220) which possibly - like yours - does NOT have the necessary software to link with the 'auto adjust brightness' system within the Charms Menu. You should however be able to adjust brightness (and anything else) via the controls which will I expect be built into the side (or along the base) of your screen.If you haven't already got a copy of your manual you can download a PDF from Samsung which will show how to make the adjustments you require.

Hi -
Do you have any buttons on the lower part of your Monitor ??
If you do, one of these usually has a Menu included, and options to adjust Bright / Contrast Etc -

I would assume that the Fn keys relate to accessability options and they come from emachines. what driver upgrade have you done so far?

So I have read a lot of diffrent ways to solve this problem and I have searched for hours looking for a solution, yet nothing i've tried has worked for me. Whenever i press the fn key and try to adjust brightness then it does't, it does pop up the slider at the corner but it only moves upwards and downwards only one level yet the brightness wont change even that much. I only found one other person that had this problem and he got it solved, but he had an Asus laptop and he got it fixed with some Asus drivers but i have a Dell Vostro laptop. One of the biggest suggestions i have found that has worked for people has been to install some older display drivers, but that hasn't worked for me either.

alright, can someone tell me all the 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).

WinKey+I and then in the lower right near the power button is the brightness adjustment.

Most laptops have function keys to adjust brightness as well, but you usually have to install a driver.

Hello, after updating to Anniversary built my screen brightness automatically brightens n lowers., despite brightness setting LOW.. One more issue with regards to Wi-Fi is tat it automatically getting ON without manually doing anything.. Please guide me

A:Screen brightness and Wifi

The brightness issue could be due to a faulty sensor, but it could also just be a result of the upgrade.
Try a few soft resets and if needed a hard reset.
Just adding this, sometimes it can take the phone (sensor) a second or two to "remember" which brightness setting was selected

I was very grateful to forum members for their response to my first question here, and I'd like to ask another, on a different matter.

I run 8.1 on a Dell laptop. The screen is extremely bright and glaring, very hard on the eyes. When I turn down the brightness to an acceptable level, text loses definition. So I've tried new themes, both Windows and also Firefox add-ons. But then I find photographic images from news sites such as Yahoo disappear - not all of them, but some. Is there any way of preventing this?

Thanks for any help.

First of all: lowering brightness does not help, I tried it.

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.

Hi, i've upgraded to windows 7 recently on my laptop and i think that it's really great compared to vista.

I have no problem with most of the things except for the ability to adjust brightness.
I could not change brightness the way i used to by using the FN + left/right key, nor the slider in power options menu.

The screen seems to be at the maximum brightness,which in turn causing my eye to hurt after some time of usage.

Any idea why? I need some help here.
Btw i am using Aspire 6935G.

it's likely you will need to install a utility for that control to work

Ok did some searching , goto the acer website\ support and pick > notebook > aspire > 6935G > then pick your Operating System and make sure you have all the drivers and applications they list

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.

What do I do?

Contact the shop that did the replacement, and ask them why it doesn't work now.

I want to reduce brightness of screen. NOT whole screen but only white pixels of screen.

Or a software that can force the graphic card to show grey or light grey or any other color instead of white. And all those pixels in screen that has other color remains unchanged. Is there any software available for such purpose? Or is it impossible to make such software? so i stop searching

I have windows 7, 32 bit

A:Reduce brightness of Screen (Not whole screen)

White is created by every component colour (i.e. Red, Green & Blue) being displayed at maximum brightness.

If you reduce the brightness of White, every other colour will (by definition) be less bright.

It could make sense at lowest level, but it occurs at 63% screen brightness and lower.

Is it due to my monitor malfunctioning or graphics card?

Is it because I never install upgrades of geforce?

Virus's /spyware can't affect your monitor's OSD from popping up. That is controlled purely by the monitor. Probably, wither the OSD button is stuck pressed and comes up every once in a while, or there is some dirt in the button, producing the same effect.

It seems to be intact. I am really wondering why these two buttons are not functioning though it was working fine earlier.

Hi guys, mine is a very unusual predicament, 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'd really appreciate your reply.

Thanks in advance.

A:Automatically changing screen brightness

I've heard of screens that adjust the backlight brightness depending on the content of the screen - the idea is to "fake" a greater contrast range with whiter whites and (particularly) blacker blacks.
I suspect that your screen is doing exactly this and it isn't a software issue at all...I don't know your machine but wonder if there might be a BIOS setting to disable this feature, maybe...
