Adjusting Brightness in Display Driver

Q: Adjusting Brightness in Display Driver

I recently upgraded from WIN98SE to WINXP. Before the upgrade I used to go into my Display settings to adjust the brightness on my monitor through the video card, but now through XP I cannot find that function. My video card is a Nvidia Riva TNT2 64MB card. I have a brightness adjustment in the monitor settings, but that is already adjusted at 100% and I need to adjust up a little bit more. Does that make sense? Does someone know where I can find this now that I am on XP?

Preferred Solution: Adjusting Brightness in Display Driver

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Adjusting Brightness in Display Driver

Uninstall your NVidia display adapter. Run one of these to be sure all the driver files are removed: Driver Cleaner Professional or Nasty File Remover.

Then, install the most recent driver:


You'll find color, brightness, gamma adjustments in the advanced display properties and a separate adjustment for DirectX overlays, such as video player windows.

I have a NIVIDIA RIVA TNT2 MODEL 64P monitor with Windows XP installed. The brightness, color etc. on the monitor seem to be at the max but all images/pictures/movie files etc are very dark. Is there any other way to adjust the brightness on the monitor?

A:Adjusting Monitor Brightness

I think that's just your video card type. If your monitor is old and this has been gradually getting worse then it could be going. You can usually adjust the brightness with your video card settings.

Right click desktop, choose properties, settings, advanced. You may have to try a few of the tabs to find the controls.

Hi all,

Last tuesday I've received my new laptop / netbook: Asus X205TA. After installing everything I found out that my brightness isn't adjusting. I've tried to:
- Use all different ways to adjust brightness (charms bar, shortcut, power plan settings etc.)
- Windows update
- Update Microsoft Basic Display Adapter drivers (there are no updates available)
- Disable and re-enable the Display Adapter

Yet: it's not working. I've also have a problem booting up games. Even the simplest of games (as the netbook is low-spec) are either not booting up, or they show errors about not being able to access the video card or so. I wonder whether these issues have something to do with the brightness settings.

I'd appreciate any input from you guys


A:New laptop not adjusting brightness

Well issue is that your graphics cards drivers are't installed, nor detected! So you are stuck with Basic Display Adapter Drivers

I had a look at the specs and it says "Integrated Intel? HD Graphics" which isn't helpful as there are different models of the Integrated Intel? HD Graphics

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?

And the second question, if this is a common problem, maybe there are some known settings that would take Windows 7 brightness closer to Windows XP and earlier versions?

A:Adjusting Windows 7 brightness - what's the best way?

If these are new laptops then, yes they will be brighter then older computers. But it has nothing to do with Windows. It has to do with the display themselves. A lot of the new LCDs on modern laptops are brighter quite a bit brighter then previous generations in part, moving to LEDs for the backlight.

Hi there guys,

I have a problem with my dell inspiron m301z laptop,
Whenever there is something dark on my display ( this could be a picture or a website or something else) my brightness automatically adjusts to that environment. So its like the brightness is adjusting automatically depending on the virtual environment. I looked up the forum for similiar problems and tried some things with the power options and stuff but couldnt not fix it..

However this does not happen when the adapter is plugged in, everything stays equal all the time,

Thank you guys.

Hi All,

I have an ASUS S400CA running Windows 8.1 (64 bit) and I am having a major issue. When I click Fn + F5/F6 to increase or decrease the brightness, nothing is happening. The slider is stuck beyond a point and the brightness does not change regardless (it is stuck at the highest setting). I have tried to fix this issue by changing brightness settings in the Control Panel, Battery Options, etc. but nothing is working.

How do I fix this issue? Is this is a driver issue? I have tried to find previous versions of the Intel HD Graphics 4000 Driver on the Asus website but only find the one I am using. What should I do? This is urgent!

Thanks so much!

Hi everyone, I have a pretty weird tech problem.

What happens is, whenever I adjust my monitor's brightness (from its physical buttons) the screen turns black. However the monitor is still on, the LED is still green and the computer is still responsive, the screen just turns black.

I can use the computer just fine, as long as I don't try to adjust anything. If I do want to change something, I have to change the values a little, then restart, change them again, restart until I have the values I want. This problem appeared when I tried to adjust the brightness by keeping the + button pressed down, so it increased quickly.

Is this indicative of a dying monitor ? It is pretty old, it's an LG L1750SQ, 17 inch LCD, it's over 4 years old. Also, I do not believe the video card to the problem, since it stays pretty cool, it has a good heatsink on it.

I just got the HP Pavilion 27xi IPS LED Backlit Monitor at work, working on a computer running Windows 10. I'm pretty tech-saavy, but I cannot figure out how to adjust the brightness! I've tried the F9/F10 function; doesn't work. I then thought it might be an issue with the driver, so I went to Settings -> Displays -> Advanced Display Settings -> Display Adaptor Properties -> Monitor (tab) -> Properties -> Driver (tab) -> Update Driver but got the "The best driver software for your device is already installed" message. Under the Settings -> Displays screen, there's no option for adapting the brightness and I've scoured the forums, but none of the solutions presented are working. Should I manually install an older version of the driver software? Any other potential solutions?

Hey, having some display problems.

I built my tower a few years ago, so everything is custom. Ill list the specs that I know at the bottom.

I got a PCI-e graphics card awhile back and installed it into my computer. It has a S-Video and DVI ports in the back of it. S-Video ran to my TV while the DVI ran to my monitor. Everything ran fine until it stopped recognizing my monitor. After awhile it started to again, then finally stopped.

I was trying to fix it tonight. Rearranging cables, unplugging and replugging the card never helped. I was gonna get my onboard VGA to recognize my monitor and reinstall the graphics card. I ended up going to BIOS and unselecting "PCI-e" (my graphics card) for my display. OOPS!

Now I get no picture - on boot up or while its on. Both screens are pitch black. The computer boots on, I hear windows load, but I can't view anything. I can't get back to my BIOS to enable PCI-e again. Ive unplugged and replugged the graphics card, hoping that made a difference, but nothing. Any suggestions? Thanks in advance!

I have an M1330 with the Intel graphics and the LED backlit display. I'm running Windows Seven RC1. I cannot adjust the brightness of the display at all in Windows Seven - it doesn't matter if I use the FN+Up / FN+Down keys, the brightness option slider bar in Windows, or adjust it in bios. The back light is either at 100% brightness, or it's off completely.
Anybody know of a fix for this?

Best anyone can say for those settings is whatever is the most comfortable and looks best to you. No two monitors will look the same, and what someone else uses can and will in most cases be totally inappropriate for you.

You can make the adjustments using the settings in the CCC, or you can uses the controls built in to the monitor and run through Windows display calibration wizard,

Heyy everyone,

This is my first post on this forum, and it has taken me a while to post this thread since I have been trying to research and figure out my own problem myself by searching many, MANY, other related forums but so far have had not much luck. Also, obviously I couldn't find an individual who had the exact same specs as my computer who had the same issues, so I am going try and get help through this thread specifically for my computer. First I will explain everything that is going or happened and then all the specs are at the end of the thread.

Recently I downloaded a trial of World of Warcraft just to start playing it again for a little bit. I played it for about two days and then after playing it for about an hour or two straight, all of a sudden, the video card craps out, screen flashes, goes black, and then comes back within seconds. Then a message error pops stating 'Display driver igfx stopped responding and has successfully recovered.'.

Within those two days I was playing though, I was doing a lot of updates on my computer since I reformatted my laptop recently. So I thought maybe it had to do with the updates and decided to do a system restore. Of course with my luck, the system restore failed, and failed a couple more times after trying again but at different restoration points/dates. So then I decided so continue with my updates since I still had to install services pack 1, more updates, service pack 2, and more updates.

I have a T500, with the latest updates from Lenovo and Microsoft.  It's running Windows 7 Professional, 64-bit. When I press one of the silver volume buttons above the keyboard (volume up, down, or mute) a black box appears near the bottom of the screen with a speaker icon, and a gray and white bar indicating the level, and white number on the right.  This seems to work correctly, and the buttons make the number go up and down, and white bar grow and shrink as expected.  Similarly, the Brightness (Fn-Home and Fn-End) make a similar box appear, which also seems to work correctly. The problem is that after I've done this, the black box does not go away, and it obscures that area of the screen.  I expect it to stick around a couple seconds after I've pressed the buttons.  But it is still sticking around HOURS after I've pressed the buttons.  If I Lock the computer (using Windows-L) the lock screen does not show the black box, but when I unlock it, the black box is there again.  This seems to happen every time I've used either the volume or brighness buttons.  The only way I've found to make it go away is to restart the computer. This is a new problem, and I suspect related to a recent update.  I've only noticed the problem in the last 2 weeks, and am quite sure I've used the volume keys before without this problem (actually, I seem to remember not a black box, but green bars and a number appearing on the scree...

Hi there, i have just upgraded my Samsung R510 Laptop from vista home premium to windows 7. After i had done this i thought everything was briliant (Alot better than vista). However i realised a few problems had occured. Firstly my mouse had no scroling function which i resolved downloading the Synaptics Touch pad drivers, then the volume indicator wasn't showing, which i have resoved also. however i cannot seem to locate a solution to the brightness display indicator missing.
By this i mean when i attempt to adjust the brightness of the screen by holding FN and Left or Right arrow, nothing happens. Before i updated, an on screen indicator came on the screen showing me if i was decreasing or increasing the brightness, now nothing??? Any ideas. Sorry if this is a noobie mistake. Many thanks in advance for any help you may be able to offer.

Check to make sure you've updated all your drivers to their respective Windows 7-compatible counterparts, so head over to where you originally downloaded the updated drivers for your touchpad (presumably the Samsung website somewhere) and see if there's anything there that can help.

How can I adjust the display brightness in XP? On battery power, the display automatically dims. I want the display to stay at a constant brightness when on battery or on AC power.

When plugged in, my aging laptop's LCD brightens, however it seems as if the power supply cannot handle the increased load, so there is a very annoying flicker; it gets dim, then bright, over and over.
