Brightness of my screen

The brightness control key on the keyboard of my hp pavillion g6 is not functioning. Earlier it used to work, and I could adjust the brightness of my screen. But now its just not working. Kindly notify me whether it is a driver or software problem. I had upgraded my laptop to the latest windows 8.1 6 months ago and didn't have any problem. Kindly mention the driver or softeware which I need to download to solve this problem.

OK. Then uninstall them all. It won't hurt anything.
The alternative is to perform a factory image recovery. That would seem to be a bit extreme in my estimation.

Brightness of the screen

I have an iMac with latest updates and disc permission always done.
However, whenever I restart the computer the brightness of the screen is almost all the way down. I always have to go to the prefs and crank it up again.
Is there a way to fix this?

See if this helps from the Help Menu.
If the images on your display are too light or too dark, you can adjust the display’s brightness.
To adjust your display’s brightness, try one of the following:
Use the brightness control keys. On portable computers, they’re usually the F1 and F2 function keys. On some computers, they’re the F14 and F15 function keys.
If you have a portable computer with ambient light sensing, select Apple menu > System Preferences, click the Displays icon, and then click the Display tab. Select the option to turn on ambient light sensing.
The display automatically adjusts its brightness to match the current lighting level.
Open the Display pane of Displays preferences
Choose Apple menu > System Preferences, click the Displays icon, and then click the Display tab. Drag the Brightness slider to adjust the brightness of your display.
Check the documentation that came with your display to find out how to control its brightness.
Depending on the type of display connected to your computer, the Display pane of Displays preferences may contain a Contrast slider that you can use to adjust the display’s contrast.

Can't use F5 and F6 keys to adjust brightness of LCD screen

I just bought a new Macbook (first one ever, new to Mac). I can't adjust the brightness of the LCD screen with the Function keys. When I do it, the icon pops up in the middle of the screen showing that it is being adjusted, but it does not change the brightness of the screen. I have turned off the auto adjust based on ambient lighting feature, and still not working right. I can adjust it by going into system prefs, but I would like to be able to adjust it using the function keys... Can anyone help with this? Thanks!

I am an idiot... i was adjusting the brightness on the keyboard backlighting, not the lcd screen.... woops!

Adjusting the sound and brightness of the screen

In SL i could hold down "shift" and "alt" and then adjust the soundvolume and brightness of the screen mucth more accurate. I have tryed the same thing in Lion, but nothing happends. I can adjust normaly, but I can't adjust it quite as accurate.
Anyone know how to fix? Different keybindings in Lion?

If I understand properly, Arrays are in essence an arraylist of arraylists.Arrays are fixed-sized, ordered containers of data (either primitive data or object references).
ArrayList is actually built on arrays.
Regardless, I'm not that familiar with how to work with them.Until you familiarize yourself with them, you won't be able to solve this problem (and many others as well).
As diligently as I've been googling, I cannot find a way to explicitly set the saturation or brightness for an RGB object, possibly because that RGB object is a Color, and if I get you, I can't set the S or B for an already instantiated Color.A Color object represents a Color defined by it's RGB values.
The Color class provides methods to calculate the HSV values for a given set of RGB values and the other way around.
The Color class provides a method to create a new Color object given the RGB values.
Sounds like that's everything you need to solve your problem.

Odd... went to get cuppa coffee, came back my monitor was BRIGHT orange, full screen,, with slight vertical rib pattern, kind of like corrugated cardboard... very slight pattern... what gives.... oh,, everything was frozen, no cursor no keyboard, zip.

Odd... went to get cuppa coffee, came back my monitor was BRIGHT orange, full screen,, with slight vertical rib pattern, kind of like corrugated cardboard... very slight pattern... what gives.... oh, everything was frozen, no cursor no keyboard, zip. Used back off button. Turned it back on, everything normal...
Had lots of sudden closures like this lately... but usually gray, black, deep blue screen... a couple with the same vertical corrugation pattern only in two shades of pale gold, or grays... what good times we have with apple... never know what'going to be looking back at you next. But BRIGHT ORANGE? Help???

Sounds like the graphics card. Run the Hardware Test in extended. Not a great diagnostic, but should pick up something really blatant like this.

Please I need to know what do I have to do.

If you can't enter the passcode then you have to place the iPod in recovery mode and then restore the iPod via iTunes. For ecovery mode see:
iPhone and iPod touch: Unable to update or restore
Note that this requires using the sleep/wake button. If you are not successful then there is nothing else that I know you can do.

Today my mac won't turn on at all...the light at the front is remaining on and at a constant brightness however the screen is still black! I'm not sure what to do next?

If you can log in blindly or using the flashlight method, it is possible your screen brightness somehow got set all the way to nothing. I don't have my Macbook with me right now to test it out but I believe it may not be possible to adjust the brightness at the log-in screen so you have to be able to log in first (though I could be wrong on that).

The screen of my imac always goes to the maximum exposure. Then the light icon on the screen. After reducing the brightness goes my screen after a few minutes back to the maximum intensity with the brightness icon back on my TV screen.

Try resetting the SMC and if that doesn't work then reset the PRAM too.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

MacBook Pro Repeatedly Loads Purple & Teal Stripe, Gray, Light Blue, Bright Blue and Bright Blue Stripe Screens Instead of OS after Optical Drive Replacement by Apple (PICTURES INCLUDED)

17 inch March 26-29 (order date – shipping date) 2011 MacBook Pro, 256GB Solid State Drive, 2.3 GHz Quad-core Intel Core i7, 1 processer, 4 Cores, 256 KB L2 Cache per core, 8 MB L3 Cache, 8 GB Memory (8GB 1333MHZ DDR3 SDRAM - 2X4GB), AMD Radeon HD 6750M Video Card, Intel HD Graphics 3000 with 512 MB total of VRAM. 110 GBs of free/unused disk space remaining.
Full Specs are in subsequent post.
The issues described in the title continue even after I’ve reinstalled the operating system twice (Snow Leopard) and installed Mavericks (which is working fine and even faster). I’ve tried many commands to repair this.
If anyone has experienced any of the symptoms above or below, your advice and response will be much appreciated as well as marked. These are the details:
My Early 2011 MacBook Pro has had the typical blue screens, screen freezes and graphics issues since I bought it about three years ago but nothing like this and NEVER any load issues until about a month ago. That was when my superdrive replacement was put in.
Since then my MacBook Pro will go into hard freezes or kernel panics. Then I’ll have to power it down manually and power it up manually. It’ll then refuse to load the OS until after multiple tries. It started out just 2 or 3, then 4 or 5, then 6-12, then 20. Now it takes over 30 boots to load the OS. These boot issues also occur even if it doesn’t freeze, i.e.: when I shut it down or restart it naturally (via the Apple menu, etc.).
95% of the time it’ll load to a gray screen instead of the OS. 4% of the time it’ll load to a light blue screen. Then there are the others: the first time this happened it loaded to the striped purple and teal screen shown in the picture. This happened the next four times then intermittently for about 5 or so more times.
It also loaded gray flickering screens. Flickering screens also occurred right before it froze and had to be manually powered down and up. Then it began to load regular gray and light blue screens and all flickering screens stopped. And then bright blue screens a couple times intermittently for a few days, sometimes with lines. Sometimes it’ll load to a blank/black screen as well. I’d reset the NVRAM and SMC but it still continued, happening multiple times a day, each time taking more and more hard shut downs and hard power ons to finally load the OS.
Until I installed Mavericks, every time it finally loaded the OS Finder began indexing. After Mavericks this has occurred 95% of the time.
After talking to Apple Support they had me do a NVRAM and SMC reset again over the phone. The MacBook Pro refused to load the entire time we were on the phone. After the call it got worse. It froze over 6 times that day and at worse took over 30 boots to load the OS.
I finally had time to deal with it the next day when it froze again. After over 25 boots it loaded and I put in the Snow Leopard OS dvd and ran Disk Utility. I verified the hard drive and it said it was fine. Repaired the disk anyway and it gave this message at the end:
“Updating boot support partitions for volume required”.
Next I tried to start in safe mode and it just hung up for hours. Then started up in single mode and it loaded the OS. It then loaded normally for three times in a row. I reinstalled Snow Leopard. Everything loaded normally. I waited an hour or so and then I downloaded Mavericks. 5 or so hours later Mavericks was installed. Everything hardware wise was fine for a day and all software issues were easily fixable incompatibilities. My Mac was even faster with Mavericks. However, Photoshop did give a perhaps relevant message:
“Photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements. Check the video card manufacturer’s website for the latest software.
GPU enhancements can be enabled in the Performance panel of Preferences.”
(I have OpenGL enabled in Photoshop and it was already checked when this error occurred).
Two days ago I went to Disk Utility to repair permissions while logged in to a non-admin account. Verified and repaired the disk, then verified permissions. Everything fine. After repairing permissions however, it gave a weird error box:
"Unapproved caller, SecurityAgent may only be invoked by Apple software".
The box stayed “stuck” in the Disk Utility window. My MacBook Pro then failed to do anything. I manually powered it down and up. It loaded to a gray screen with the error message box again: "Unapproved caller, SecurityAgent may only be invoked by Apple software".
It then refused to load anything else but this message box on a gray screen even after rebooting it multiple times in safe, verbose and single modes and after resetting the NVRAM and SMC. I went online with an iPad and entered in the error and got some advice. I tried to run fsck and erase the /var/folders/ via single user mode but it still loaded to a gray screen with the error message. I just decided to skip to the end and Cmd-R loaded into recovery mode and reinstalled Mavericks again. That worked: the message has not appeared since.
Some people have said this error is related to a hard drive cable failure. I know that this cable was tampered with during the optical drive replacement procedures because I watched them do it.
Everything was fine for a day. Then yesterday my MacBook Pro froze while trying to open a VLC file. It took 12 boots to load the OS. I tried single mode once and verbose mode once. 10 times it loaded to gray screens, even in those mode. A Safe boot lead to a bright blue screen. Finally reset the SMC and it loaded on the 12th time.
Just five hours ago the same thing happened except it took over 30 boots to load the OS. Single, verbose and normal boots, NVRAM and SMC resets lead to gray screens. Safe boots lead to bright blue screens with and without lines (see pictures). Finally loaded on a normal boot.
I know I should have tried safe booting, verbose, single and recovery modes, disk utility, fsck and other command methods earlier this month but in the end, these methods have not solved the problem anymore than resetting the NVRAM or SMC.
There seems to be conclusive evidence that it’s a hardware problem, stemming from last month, the FIRST AND ONLY time my MacBook Pro was opened up. Maybe it’s the hard drive cable, but it could also be the graphics card and/or logic board (something that’s always been defective on this MacBook Pro, in my opinion). Many early 2011 MacBook Pro owners have given evidence to the latter possibility online.
The first time it started it seemed to stem from me using iPhoto and Photoshop a lot. I had both running continuously for about two weeks. This is another reason for suspecting the graphics card/logic board is at fault (in addition to three years of screen/graphics glitches). And since the card is soldered to the board and the board connected to the cable...I also have serious battery draining issues, something else that got bad after the Apple Superdrive repair. And the battery is connected to the board...
Also, since downloading Mavericks, windows from every app get blurry/fuzzy when I scroll or zoom in. I have read that this is happening to a lot of folks though for various reasons.
I guess it could always be the hard drive. I just don’t know. I’m taking it in to Apple, but can't right away because it’s not local. I know they’ll be able to run a test on the hard drive. I wanted to see if anyone else has had this problem (especially the purple and teal striped screen) before they start poking around, possibly creating another problem that goes beyond my Apple Care Plan allotment.

How can I reduce the brightness of my screen?

I installed WIndows 7 on my MAC and after installing the boot camp drivers, the screen went really bright.
I reduced the brightness to the lowest setting on my keyboard, but it is still bright.
The problem is not so much on the graphics, its more on the brightness of the white background & black text.

I would adjust the keyboard setting back to midway before calibrating, this way you have some flexibility to use that again.

How to increase "brightness" of Display Screen on ...

Hi I have just up-graded to to a Nokia 5800 XM which seems the "bees knees" to me as I have never had such an all singing and dancing mobile phone before (had a 6230i about 5 years as my up-grades usually went to daughters or not taken but 6230i lost it's life a couple of weeks ago when it toook an accidental dip in the washing up bowl *) )
I like lots about the new phone , especially the QWERTY keyboard - I can actually do texts now as the old way on key pad took me forever! Oh and handwriting tablet is great - can even write texts!
The only down side is the "display screen" seems rather dim in average to bright daylight ( I am not visually impaired not particularly mentally impaired either as a teacher) SO DOES ANYONE KNOW HOW TO MAKE THE SCREEN BRIGHTER?
Thanks Bri

The 'Brightness/Contrast' dialogue screen becomes unexplainably absent in PhotoShop 7.0 on XP

About every year of so the 'Brightness/Contrast' screen becomes unexplainably absent while using my PhotoShop 7.0 in XP. When I click on 'Brightness/Contrast' the eyedropper becomes active as usual but the dialog screen with the two 'sliders' for brightness and contrast is not visible. Where is it? If I uninstall and reinstall it's OK again for a while.

It's not unheard of for dialogs to become lost off screen. It can happen
when you reconfigure your display rez, or rearrange monitors.
Before you re-install (assuming this happens again), try resetting your
prefs by pressing the ctrl-alt-shift keys during startup.

Hi,
Recently my MBP randomly has the lowest brightness after i come back to login after a lock screen... any solutions to this?

Goto
System Preferences> Keyboard>
and make sure "Use all F1, F2, etc. keys as standard function keys" is unchecked
Alternatively you can try pressing the function key on your keyboard in combination with the brightness keys. (fn) lower left.
