Failure of Shades, DarkAdapted and Brightness Control

My iMac display is too bright even at it's lowest setting.
A new profile in Display Preferences can't deal with this and the contrast control in Universal Access also doesn't help.
I've tried 3rd party software. Brightness Control continually loses it's setting when the screensaver starts. Shades doesn't work for me because it leaves the pointer undimmed and that small too bright area is right where I need to look. And DarkAdapted is limited by the same screensaver problem as Brightness Control.
I sure wish Apple displays could dim adequately as in the past.
Any suggestions appreciated.

I have DarkAdapted Pro, with registered version, it load your profile at mac os login, and darkadapted its a real bright control, not like brightcontrol (deform colours)...
One question, do you have bright gradient left to right on your mac 24 alu?.. more bright at left side of your monitor, to view this, move one window at the left, and then move it at the right, if you see one variation of white values then the gradient is there!... ok it is my problem and a lot of people are at the same situation like me... not sure if it is a general problem...
Ok see you bye!

Volume and Brightness controls

So I was installing Lenovo Drivers on my laptop after I nuked the hard drive and to repartition. However, somehow, I have TWO volume and brightness controls. Any ideas anyone?

Hi ychen428,
I saw your other post over here . Is your audio working properly now with the exception of having two volume controls?
Seeing as how the hotkeys are incorporated into Energy Management, could it be that there are two versions of Energy Management installed? The on screen displays look like an older version and a new version.

Windows 8.1 update and brightness control

I have a DELL XPS L521X with Windows 8.1 (I had windows 8 some days ago) and I have had two problems:
1) I did not allow Windows to upgrade to 8.1 and it forced me to do it. It gave me 15 minutes to save progress and do it. I was watching the NBA finals on my computer and it was the only thing I had to watch the game. The installation lasted the whole second
half the game and I WAS NOT ABLE TO WATCH IT DUE TO THIS, YOU CAN IMAGINE HOW I AM FEELING ABOUT NOT USING WINDOWS EVER AGAIN... How can I prevent it from ever upgrading anything without my consent? I had already turned off updates from Control Panel\System
and Security\Windows Update but it didn't help.
2) My brightness control became broken after the 8.1 update. I had to manually pick the older Intel HD 4000 driver to have it working again or else my eyes would stop functioning after such a bright display. I had to switch to the 9.17 driver version from
September 2012. Where can I get the lastest WORKING version of the driver?
Please stop making me loose days fixing Windows issues...

Hi,
We have set the GP to disable Windows 8.1 update in Windows store, you can check it here:

For your second issue, it's not only related to Windows, but also the driver provider. Microsoft is working together with the device manufacturers and partners to deliver update package and try the best to solve the compatible issue and bring a great improvement
on user experience. But you know, it will take some time.
Thanks for your understanding.

Keyboard: audio and Brightness control keys not working with or without fn

The Keys for controling Audio and Brightness (F1-F5) do not work.
Also combined with pressing the "fn" key the keys do not work.
So i only control audio with the remote control or the slider in the menubar.
Making a reboot with deleting pram didn't help.
I'm running the up to date version of leopard on a macbook pro (core2duo).
I also searched in the forum for this problem.
I oten read about "sytem control"-"keyboard and mouse"-"keyboard" and the F1, F2, etc. to use as...
but switching this button on or off doesn't change anything.

problem solved:
the couse was the software update 1.1 for macbook pro, because there i had the problem like in this thread: http://discussions.apple.com/thread.jspa?messageID=6142512&#6142512
and did the solution like that, but there i maybe made some mistakes with renaming and copying, so i rinstalled the update and renamed it a copied to plugins, and now all works as it should.
thanks for help

No TrackPoint Scroll and Brightness Control After Resume

Hello All,
I'm having an issue with my new x120e where after a couple suspend/resume cycles both the Trackpoint scroll function and the ability to adjust screen brightness no longer work. Using the Trackpoint only yields results as a pointing device, and trying to use the brightness controls does nothing--no on-screen brightness level display. I've searched the forums but couldn't find these exact issues, and I'm using the latest versions of the UltraNav driver and Utility.
Thanks!

hey cbolos,
check via http://support.lenovo.com and see that your Power Management software is at its latest version. If not, download and install.
if it is the latest, uninstall all UltraNav drivers+Utilities and the Power Management.
let window install its generic drivers. Test and see if it happens again

Qosmio F55 - Replaced LCD and brightness controls are backwards reversed

Hi,
the LCD for my Qosmio F55-Q502 cracked and I ordered the same part and when I installed it, everything works nice and all but the brightness up and down are reversed. Like Fn+F6 makes it brighter while Fn+F7 makes it darker? The original that came with it was a lp154wp1 (tl) (e1) but one I got is a lp154wp1 (tl) d1).
Does anyone think that bit of a variation of the model can make it reverse the controls? Even on Windows when you slider the brighness to the right it will dim and to the left it brightens. Also for anyone else that needs info on their Qosmio F55, the original is a lp154wp1 (tl) (e1) and its also known as lp154wp1 (tl) (a3) that is written on the lcd board.The replacement lp154wp1 (tl) (d1) is also known as a lp154wp1 (tl) (a2) also written on the lcd board
Any suggestions or help would be appreciated!

Hi hulkster,
Where you have ordered the new display and is it an original Toshiba spare part?
If yes I would contact an authorized service provider or the shop where you purchased it. In my opinion the screen is not 100% compatible to your model. This would also explain the different part numbers that you posted

Windows 7 "Dim the display" and brightness controls missing

Is this another driver problem? I would think the Nvidia drivers would support this new feature in Windows 7.
http://www.technospot.net/blogs/windows-7-automatically-dim-display-screen/

I suspect you need another driver (not the video card driver) since these function require control of the backlight. It seems Apple does not provide a standard driver that can be used by Windows as the display brightness can only be controlled through Apple's bootcamp drivers in the bootcamp control panel or using the keyboard shortcuts.
Even in Vista, if you go to the Windows mobility centre (Win+X)there should be a panel for display brightness. This panel is missing in bootcamp, suggesting the necessary drivers are missing. This is a shame, but I wouldn't hold my breath for Apple to ever provide these. Then again, I didn't think Apple would ever fix the touchpad drivers for Windows, but they seem to have finally done so in the Bootcamp 3.0 beta drivers, so maybe someday...
Windows 7 also supports automatic brightness changes based on an ambient light sensor, but again, no appropriate driver supplied by Apple...

4K Rendering, DPX Files, and Brightness Control

First off- when will Premiere Pro CC allow for 4K rendering? This is a new standard and currently the program won't support exporting to 4K compressed files. The reason I want this is because I use 4K and want to keep it in its native format, and also because I want to save it to a 4K Blu Ray when 4K Blu Rays will be announced late this year.
Also when will Premiere Pro allow for odd frame rates when importing DPX files? Currently it only adds a few options for frame rates, so I have to use After Effects to set my frame rate to 18fps, and then load that into Premiere Pro. It seems stupid to have to use one program to set for one thing, and then use Premiere Pro to do the work needed.
Also I have some files that need brightness correction. Without using Auto settings, how can I manually adjust the brightness of the video to where I want it set? I don't see any option in Premiere to correct for brightness, without using an auto setting. I tried auto contrast and some of my video was still too dark. And I really don't want to have to use another program just to correct for this, as this should be an option in Premiere for the price you pay to use the program.

OK, let's address the current issues first.
There are a few different frame sizes that lay claim to the "4K" name. 4K resolution - Wikipedia, the free encyclopedia
What is the exact frame size you want to export?
The most commonly used export format nowadays seems to be H.264. When 4K Blu-Ray To export to H.264 I use the following settings, although actually not quite 4K - it was the size I was asked for with this project example. It was a talking head so I was able to get away with a reasonable bitrate. You can change it around to suite your needs.
The next topic seems to be the Brightness and Contrast effect. I found it on the Effects tab in the Video Effects/Color Correction section.
As for importing your image sequence, feel free to import it at 24fps, then interpret it the way you want it. I suggest that you import at 24, then create the sequence from the imported clip.
Then right click on the video clip in the Project Panel and interpret it to 18fps. Then drop the 18fps on to the 24fps sequence. It will play at 24fps by duplicating some of the frames. There is no way to really get around that other than play it back at 18fps. Not a great option.
Now, I highly suggest that if you are going to use Premiere Pro, that you take some lessons. The best are from Lynda.com but there are free ones for CS6 that still apply to CC at CreativeCOW
There are many ways in Premiere Pro to achieve the same goals and there is so much to learn. You might want to start with How to create a video story with Premiere Pro | Adobe Premiere Pro CC tutorials
Good luck, and let us know if you have any more questions.

IDEACENTRE A720 serious problem with noisy hdmi in and brightness control

First of all, excuse my English. (And after initial posting i recognized that i have selected the false category for this post, should be in "ideacentre"....)
A few days before i buyed a used VBT1YGE from Amazon Warehouse Deals. It was important to me to use the A720 as a external monitor for my Lenovo Notebook and my MacBook.
As soon as i connected the Notebook or MacBook with a HDMI-Cable (tried four different cables!) plugged in to HDMI in, there was an annoying noise.
Furthermore, if i adjust the brightness with plugged in HDMI-Cable, there was a new loud noise, it becomes louder by decreasing brightness. Sound works fine from the Lenovo Notebook through HDMI but there is always a noise and if i decrease brightness this results in louder noise.
If i use the VBT1YGE only as AIO PC, everything works fine, no noises.
As i said the VBT1YGE was used, so i thought it has a defect and i sent it back to Amazon.
Now i have buyed a new VDT2DGE from Lenovo Shop and i have exactly the same problems.
Please, is there any solution for this problem? If not, i will sent the VDT2DGE back in a few days...

I am running Windows 8, which came with the system. I decided to "Remove everything and reinstall Windows" and this is the specs that I see now. Windows 8, Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz 2.50 GHz, 6.00 GB RAM, 64-bit Operating System, x64-based processor.
By chance I found out that if I force my screen to sit up right, by pushing the backbone of the screen backwards, the noise becomes smaller. I also now changed my refresh rate to 50Hz to make the noise a little bit lower in tone. I was hoping that this is fixable with an update with graphics card or with a lenovo diagnostic software, but I could not find anything online similar to it. The problem still exists, although now it is more acceptable. Still hope that it can be solved.
Thank you very much for replying!

MBP early 2007 model having issues with volume and brightness control keys (f1-f9)

My MBP, early 2007 (came with tiger 10.4 in the box) and now running Snow Leopard 10.6.8 is having some weird problems with its f1-f9 keys.
For about 2 weeks now I have noticed that I cannot change the brightness and volume (especially) using these keys.
The layout of the keys on my MBP are as attached:
I tried to google the problem and tried a few diy fix-its, however nothing seems to work... and there seems to be no clear answer either. One day, during these two weeks it suddenly worked for about 2 minutes then stopped again and hasn't worked since.
Anyone experienced any similar problems? or have any idea what I can do to fix it?
As a last resort, I would eventually get a wireless keyboard to use with the MBP.

Thanks tjk, I tried that but it did not help. However over these last 2 days I noticed something more.

The next time I shut down and restart my computer, the key problem is back again. And again I do the same procedure above to fix it and so on...
Hmmm, it sounds like a corrupt preference.
Open Console and let's see if there's anything in there to help us.

How do I remove the on-screen volume and brightness displays?

The on screen displays for volume and brightness controls on my ProBook 455 really lag behind pressing the buttons and aren't terribly helpful anyway. Can I remove them? I've seen people ask in the past and they are told about something called an "HP On Screen Display" or a "MediaSmart Menu." But my notebook doesn't have either. Does someone know another name for the thing I need to remove in order to get rid of this useless display?
Thanks.

My screen gets dim and the brightness control buttons don't work

My screen is frequently dim. The brightness control buttons display that they are working, but the brightness doesn't actually change. Any ideas why and what I can do?

Thanks for the suggestion. Actually, I had tried that but still had to go into preferences any time I wanted it brighter. After I posted, I found a thread using some different keywords and found that people were having the same problem with OS versions up to 10.7.2 but solved it with the latest update (10.7.3). I just installed it and now seem to be able to adjust the brightness with my keyboard no problem. I appreciate your reply anyway!

Brightness and volume control keys not working with windows 7?

brightness, volume control and some other keys keys are not working with windows 7 with macbook pro retina. Can I fix it?

Welcome to the Apple Support Communities
Have you installed Boot Camp drivers? You need them to make your computer work properly on Windows, and to use your function keys as Play or Pause, volume and brightness keys.
To install them, follow these steps:
1. Press the X key while your Mac is starting to start into OS X.
2. Open Boot Camp Assistant and tick only the option to download Windows support software.
3. Windows support software will be downloaded and Boot Camp Assistant will ask you to burn it into a DVD or USB drive, so do it.
4. Start into Windows, insert the DVD or USB drive and install Boot Camp drivers. Your Mac and your volume and brightness keys will be working after installing the drivers

IMac G5 (iSight) with 10.4.11: Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever. Brightness controls work normally under this circunstance. Please help !!!

iMac G5 (iSight) with 10.4.11: Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever. Brightness controls work normally under this circunstance. Please help !!!
Please don't tell me to adjust anything on the preferences, since I have tried all. I think it may be anoter kind of problem, maybe hardware related or anything.
I ran the Hardware repair DVD and everything was ok, but when the imac restarted the screen was very lit again, but when it went sleep, when it went awake again the screen got dimmed again. Because of that I think that the problem could be software related, but who knows. Excuse my english.

I can't see another possible answer - the longer your machine is up, the more the power supply is stressed, it protects itself by dimming the screen to lower the draw on it.

Photoshop's brightness and exposure controls?

Can anyone explain the difference(s) between Photoshop's brightness control and its exposure control?
Thanks,
Mark

Did it ever occur to you to consult the documentation, Mark. Say, the User Guide and/or the Help files?
Exposure command
Adjusts tonality by performing calculations in a linear color space. Exposure is primarily for use in HDR images. See Adjust Exposure for HDR image.
Adjust Exposure for HDR images
Comments (0)
The Exposure adjustment is designed for making tonal adjustments to HDR images, but it works with 8‑bit and 16‑bit images. Exposure works by performing calculations in a linear color space (gamma 1.0) rather than the current color space.
1. Do one of the following:
Click the Exposure icon or an Exposure preset in the Adjustments panel.
Choose Layer > New Adjustment Layer > Exposure.
Note: You can also choose Image > Adjustments > Exposure. But keep in mind that this method makes direct adjustments to the image layer and discards image information. Adjustment layers for 32-bit images are available in Photoshop Extended only.
2. In the Adjustments panel, set any of the following options:
Exposure
Adjusts the highlight end of the tonal scale with minimal effect in the extreme shadows.
Offset
Darkens the shadows and midtones with minimal effect on the highlights.
Gamma
Adjusts the image gamma, using a simple power function. Negative values are mirrored around zero (that is, they remain negative but still get adjusted as if they are positive).
The eyedroppers adjust the luminance values of images (unlike the Levels eyedroppers that affect all color channels).
The Set Black Point eyedropper sets the Offset, shifting the pixel you click to zero.
The Set White Point eyedropper sets the Exposure, shifting the point you click to white (1.0 for HDR images).
The Midtone eyedropper sets the Exposure, making the value you click middle gray.
=== === ===
Apply the Brightness/Contrast adjustment
Comments (0)
The Brightness/Contrast adjustment lets you make simple adjustments to the tonal range of an image. Moving the brightness slider to the right increases tonal values and expands image highlights, to the left decreases values and expands shadows. The contrast slider expands or shrinks the overall range of tonal values in the image.
In normal mode, Brightness/Contrast applies proportionate (nonlinear) adjustments to image layer, as with Levels and Curves adjustments. When Use Legacy is selected, Brightness/Contrast simply shifts all pixel values higher or lower when adjusting brightness. Since this can cause clipping or loss of image detail in highlight or shadow areas, using Brightness/Contrast in Legacy mode is not recommended for photographic images (but can be useful for editing masks or scientific imagery).
Note: Use Legacy is automatically selected when editing Brightness/Contrast adjustment layers created with previous versions of Photoshop.
1. Do one of the following:
Click the Brightness/Contrast icon in the Adjustments panel.
Choose Layer > New Adjustment Layer > Brightness/Contrast. Click OK in the New Layer dialog box.
Note: You can also choose Image > Adjustments > Brightness/Contrast. But keep in mind that this method makes direct adjustments to the image layer and discards image information.
2. In the Adjustments panel, drag the sliders to adjust the brightness and contrast.
Dragging to the left decreases the level, and dragging to the right increases it. The number at the right of each slider reflects the brightness or contrast value. Values can range from ‑150 to +150 for Brightness, ‑50 to +100 for Contrast.
