How to reduce my screen brightness

Q: How to reduce my screen brightness

Hi all,

My desktop machine is a Windows 7 32-bit. My problem is that when I read a PDF, the brightness of screen bothers me and I want to reduce it. My monitor is a Samsung LCD and only has a button. When I press it one time it turn the screen on/off and when I press and hold it, it just adjusts the wallpaper.

Is there a way to reduce it?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

my laptop is very very bright ,somehow this is one of the simple things i have not yet learned in vista. I even find my screen to bright when it's in cordless mode or power saver mode.

A:how to reduce the screen brightness in vista?

That's usually controlled by two hotkeys on the keyboard, usually using the Fn key and one of the F keys. On my HP, it's Fn+F7 and Fn+F8.
They should have symbols similar to these-
Should be shown in your User Guide, check Start | Help and Support, see if there is a link for User Guides.

You can also set Brightness for AC and Battery mode here:
Control Panel | (Mobile PC) | Power Options
Click the Change plan settings link under the selected plan, there will be two sliders to set screen brightness.

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.

I cannot find the slider of the brightness button when I open the power options in my PC. Not only that I also tried the functional key Fn+F2 to reduce the brightness but it does not works.

I shut down my laptops once every week; they're either in sleep mode or hybernating. My P50 is currenly running Windows 7 Pro with all the drivers installed. I have changed bios settings such that the function keys behave as function keys and only act as media keys (or whatever they're called) when pressed in combination with the Fn key. All hotkeys work as they are intended to.However, resuming from hybernation causes only the reduce brightness key (Fn + F5) to stop performing although all other hotkeys work as they should. Pressing the F5 key by itself works normally; its just the Fn + F5 combination that doesn't work.Anyone experiencing this ?

Im having much difficulty concentrating/reading because my screen brightness is always to bright.

I currently have my screen on the lowest possible brightness and it's no where near what i would find expectable. I don't mind lighted screens i just mind the limited options ,or maybe their is options?

I have no trouble reading a book in the dark and i find it quite unnoticed in till someone tells ask me ''how do you read in the dark''?

I'm also color blind ,i don't know if this is a factor.

Iv been looking around for a sheet of tint to put over the laptop screen ,hopefully i wont have to do this.

Since updating my HP Pavillion 64 bit to Windows 8.1, I have been unable to use an HDMI cable or reduce the computer brightness. I figured it would be a simple fix: restore to before the update, and wait for the bugs to be worked out. However, every time I attempt to access the control panel to perform a system restore, the entire OS freezes. Can someone help me resolve this?

Update: I tried to power on my computer just now to no avail. Stayed on the HP loading screen for 30 min.

A:Cannot Reduce Brightness Use HDMI or Control Panel w/8.1

Sounds like a Hard Drive issue, first things first, try checking your whole hard drive. Download Hiren's Boot CD from my link below, burn it and boot to it. Go into Dos Programs and you'll see Hard Drive Tools, pick the tool for your brand hard drive and run a full scan on the surface. You can also try GWscan, which can do both Seagate and WD drives, look for "read element failure" because that error will cause that 30 minute non-boot in some cases.

Sometimes a bad or corrupted spot on the HD will cause all kinds of other apparently unrelated and insane problems, so check the disk before doing anything else.

If you have an SSD drive in there, then do not do any of this, you will have to use the tool for the drive made by whoever made it, or simply so a CHKDSK, you can do that from Hiren's using Mini XP, it's better to do it from there rather than let Windows 8 do it, especially in the state it is in now.

A:FN keys doesn't work to reduce brightness

Hi michelewjy,

Welcome to Vista Forums.

I recommend you go to the laptop manufacturer's web site and find the drivers, firmware, and/or software appropriate to your graphics card and your monitor and your version of Vista and download them and update your system with the revised versions. Let's see if that helps. This may also be related to the SFC problem in your other thread - so I will check especially for anything that seems to apply to this issue.

I hope this helps. If not, post back and we'll try something different.

Good luck.

Yesterday I turned on my desktop PC and the desktop screen, all the icons and the toolbar was much larger than they have ever been before. I have searched the forums and they all say to change the screen resolution. I have checked this and it is 1024 x 768 and the dpi is 100% at 96. I have tried clicking the desktop and scrolling the mouse back too but nothing has worked. Another forum suggested upgrading the graphics driver which I did but that just made it worse so I uninstalled that. I also did a System Restore and that didn't work either.

Any help or advice please? This is getting very annoying, especially as I don't know what I did to get this problem.

Many thanks.

The monitor horizontal size buttons work, and the ATI screen positioning works, just cant make it small enough. Vertical is okay.

Can someone impart some basic knowledge of where this problem is likely to be?

W7 Ultimate 64bit.

I've just started to play Tomb Raider, Game of The Year edition.

(Yeah, I know it's an antique game but I've always been a late developer)

I don't want to play Tomb Raider full screen on my 24" monitor, so I have it set to display in a window of 1440 x 810.

My question: Is there an app or a shortcut that would give me a black (or whatever color I might choose) background to my windowed screen?

So when my game window opens, I can hit ......(whatever) and see my game on a background of my choosing, instead of my desktop display.

Have I put this right? Can my colleagues on W7 understand the question?

Thanks, guys and girls :-)

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.

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

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.

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.

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... Can anyone help me?

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?

Do you have the win 7 dvd to do a repair install?

See if this may be able to help. If this is for a desktop PC, then you'll need to manually adjust the brightness level on the monitor itself.

hey, i was wondering if there is a simple stand alone program that can make the screen of a computer darker and brighter (so i dont have to use the monitor controls) and also contrast?


Hi there,I wouldnt imagine that there is,but Im intrigued as to why you would want the computer to do it when you already have the controls on the moniter?

I have a problem wtih the screen brightness on my laptop. The problem is that the screen looses brightness whenever I plug-in or plug out the charger. In the display brihtness menu I have set the maximum brightness for every power plan - just in case and in advanced options I have disabled the dimming option. But the screen still looses brightness every time I plu -in or remove the charger. So I have to change the brightness manualy every time. And when I do so, lower the brightness but the brightness actually increases and I am clueless what to do.

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.

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.

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

Please don't use high case letters, they are difficult on the eye, and are considered  as shouting. To your problems did this problem exist from the start, or did it just start to happen recently? When you left click on the task bar icon for your power plan and then choose ''Adjust  Screen Brightness''you say that it doesn't work. the slider there doesn't   function at all? Are your drivers updated? Start laptop in Safe Mode and see if it works there or not! At last resort you could reinstall the software. Let us know how you go.

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

First of all, please specify maker and model of your laptop. Some vendors could have their own third party replacements for some functions.

Also, please go to Control Panel - Power Options - on the right side of your current active power plan select "Change plan settings" - in the next window click "Change ADVANCED power settings" - then navigate to - Display - Display brightness and check percentage.

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?

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.

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?

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