Lack of brightness slider

• iMac darkens when in display mode using target (TDM) and the lack of brightness slider!

  Hi all

  I use a MacBook Pro (13 "to end 2011) and iMac (27", by the end of 2012). Both are up to date, running El Capitan 10.11.5. They are connected with a thunderbolt cable in order to use the iMac as a second screen (TDM).

  Now, when I press CMD + F2 to the iMac, iMac gets used as second screen as expected, but it goes really dark! He's not black, you can still see the desktop but on a sunny day, it's really hard to see anything. Now, it's pretty embarrassing, but the second part of the question makes it a pain in the *. When the iMac is dark, I always go to the system preferences and open the settings for the display. I can see a window with the parameters for the iMac, but there is no cursor for the brightness! There is no way to make it brighter!

  The only solution is to disable the target (CMD + F2) just display mode to enable it again after a few seconds. Sometimes I have to activate the TDM twice but sometimes it takes 4 or 5 loops toggle just to see the brightness slider!

  Here is a screenshot of the settings without the cursor window

  

  And that's what it looks like after a few loops, and then I can adjust the brightness.

  

  Any ideas why this happens? Any advice on a possible solution? Why - what is darkening the iMac? Why is the cursor missing?

  Best,

  Stephan

• Satellite A350-13D - brightness slider suddenly disappeared

  Hello

  I got a toshiba satellite a350-13d, with windows 7, installed long ago worked perfectly out of the FN keys work. However it was not my problem, that I could change the brightness of the screen with the cursor provided by windows...

  But... All of a sudden, my brightness slider is over. I had not installed the new drivers, windows stopped showing me the ability to change the brightness of the screen (by clicking on the battery status icon in the traybar what he used to say 'change the brightness of the screen', and if I click on 'other options', he went too). Does anyone have a solution for this?

  I have already installed all the drivers from the toshiba site, so this isn't the problem.

  Thank you

  Hello

  Strange may this problem s registry or something like that

  You can change the brightness of the screen here:

  Panel of-> all items in Control Panel-> display-> brightness control (left)

  Otherwise, you might try to get the FN buttons work.
  To do this, you must earn 7 Vientiane (value package) and utility Toshiba Flash Cards for Win 7.

  I found the Toshiba Flash Cards for Win 7 utility on the European driver Toshiba page areas to download Satellite L500

• Print area setting of the printer - brightness slider module

  When I send my photos to the lab for printing, in order to obtain the final print to match the exposure on my screen, I have to increase the exposure in the develop module before rendering my last image to send to the lab.  In general, I add environ.4 to any exposure setting I already put in the develop module.  This usually gives me a perfect exhibition match.  Thereafter, I must then remember to adjust the exposure back on all my photos that I send to the lab.  Otherwise, I do sometimes exposure increase on a virtual copy, but then I have a ton of virtual copies extra clutter things.

  I recently learned in the print module, can I increase the brightness with the brightness slider.  If I print to jpg in the print module and use the brightness slider, I could produce my lab files and eliminate 'cleansing' operations mentioned above.  However, I don't really know how the brightness setting printer slider relates to exposure of the develop module slider.  That is, what each cursor movements are considered as equivalent - if I normally increase exposure de.4 in the develop module, how can I increase the brightness slider worms in order to match that?  I would increase the brightness of 10, 15, 20 slider... ???   I have no idea!   How these two cursor relate?

  Any help would be appreciated!

  Thank you!

  PS. because I know someone will ask, YES, I have corrected my monitor color.  However, my screen is VERY bright and I worked with the CC seller to lower the brightness of my screen and 90 lumens, but it's still too light and we cannot safely he set lower without risking damage to the screen.  That's why I regret to make the manual exposure increase.

  Rather than having to remember to reset the brightness, you can use the soft proof feature and create a virtual copy and reduce the brightness on the virtual copy. Then you can decide when / if to remove the virtual copies.

• Jumpy brightness slider

  II have undergone a strange behavior with my iPad pro. When I go to the brightness level by using the slider in the control at the bottom of the screen Center (the white one you access when you pull up), the cursor will be often "jump" away when I take my finger and find themselves either slightly higher or slightly lower than what I wanted. This happens about 75% of the time and I can't reproduce it in the display and light settings pane; It only occurs when you use the control panel. Everyone knows something similar?

  Thank you

  Yes.

  The same questions also happens with the volume slider in the rollout Control Center!

  Frustrating.

• Qosmio X 300-12 H - replacement for display a lack of brightness

  A toshiba authorized repair center replaced the original display of my laptop Qosmio X 300-12 H with one compatible that I encrypted 312 euros (540 euro for the LCD original as they say).
  I agreed for a compatible (instead of the original one) monitor because they said there is no difference between the views except the Toshiba brand!

  The problem is that the display is no brilliant way, his performance looks like if the battery was completely exhausted (although it current alternative).
  I just thought that maybe they just forgot to remove the protective film from the LCD display. But someone on yahoo answers said it is almost impossible because "these plastics films are almost impossible to forget that they usually overlap the Panel and also may contain trapped air pockets which are very visible".

  Also, when I try to increase the brightness decreases and when I decrease - increase!

  What would be the problem, guys, in your opinion: cheap, poor quality, wrong compatible display I paid 312 euros for, or poorly executed repair service and can be false connection LCD?

  I would even be willing to pay 200 euro of the difference to the original display, but I fear that they do not accept that this one already installed argumenting that they aren't resellers but just a service center!

  What should I do?

  Hi Zavarzin

  I m sorry to hear that buddy but I think that no one here can tell you the exact reason of this and if it behavior normal s for a compatible screen or not. I think this should be verified professional people (authorized service provider).

  Have you already contacted the guy again? If this isn't the case, you should do it.
  Explain the detailed situation and why you are not satisfied with the new view. I m that you can clarify this issue with the technicians if you talk with them a little bit. Normally, guys are always the best and from my own experience, I've never had a problem.

  I'm sure guys can solve this problem get in touch with them. Good luck! :)

• lack of brightness control

  When I upgrade from vista to windows 7 missing control brightness and when my laptop battery light don't overtemperature and brightness in power option is missing and I can not increase or decrease the brightness of function "fn" my laptop is sony vgn series.
  How can I control the brightness?

  Read the article: How to adjust the brightness and contrast of your monitor . You will find a section how adjust brightness automatically using Adaptive brightness.

  You will also need to go to your laptop manufacturer website and search for a drivers. It may be necessary if you want to use the keys on your keyboard to increase/decrease brightness.

  Depends on what graphics card you have, go to the manufacturer site and see is there any software for the control of your graphics card. This kind of software can automatically adjust the brightness when you unplug your laptop. It could be ATI Catalyst Control Center... but it depends on what graphics card you have, you need to find the website of the manufacturer of graphics cards.

• "Not available" brightness - can't change the brightness level

  I can't control the brightness in the settings - brightness icon bed: not available

  No error message

  Setting of power doesn't have the brightness slider

  Reinstalled the Intel drivers from the HP site with administrator installation and reboot.

  Thanks for any help

  I had this same problem on a spectrum One and it was driving me crazy! Windows wouldn't let me change the brightness no matter how, I went to this topic, and I saw that you get the message "Not available". Finally, I stumbled across the "HP My Display" program and was able to adjust the brightness in there. What is loaded on your PC? So far, it's the only way I found to change the brightness on this machine.

  After the update the BIOS to version 1.6, as even the lowest setting of the screen is bright when using the device in a dark environment (e.g. reading in bed). Before the update, I simply set the brightness slider Windows at the lowest level and everything was fine but now it is so brilliant that he hurt the eyes.

  Anyone else with this problem? Is there a solution?

• Portege R930 brightness increases when the shiny things are displayed

  I use a Portege R930 with the 2nd lowest brightness. I noticed that when something bright is displayed, the overall screen brightness adjusted upwards by about 5 tiny slices to speed increment of 1 / second.

  Increments of brightness are not nearly as pronounced as the steps in the brightness slider, but it's there. And very annoying.
  I can't find any mention of this 'feature' online. Is it possible to disable it?

  Hello

  I put t know if your laptop was equipped with the graphics card AMD but the problem, you take it all sounds a bit like a future provided by AMD GPU called: AMD vari-bright.
  Vari-bright save energy consumption by optimising contrast image on the internal LCD screen AMD computers.

  This feature can be used if the computer is running in battery mode, using the internal LCD only or PowerPlay settings under mode battery is set to maximize autonomy.

  The Vari-Bright feature can be turned on and off in CCC.

• Impossible to add an external monitor or adjust the brightness of the screen: Pavilion dv7-4031TX (Windows 7)

  Hello

  I recently replaced both hard drives of HDD2K12, which meant I had to re-enstall Windows 7. Since that time, I have no options more in using an external monitor or even the brightness of the screen. The computer does not recognize the monitor when I Plug and all my drivers are up to date.

  Can you make suggestions that could help to solve these two problems?

  Kind regards

  Peter

  Thanks to find the links but I could not find the drivers I need for a Pavilion dv7-4031TX.

  However I finally managed to fix the problem. Let me summarize what has been my problem.

  (1) I could not adjust the brightness of the screen by using the function keys f2 and f3.

  (2) I couldn't find the brightness slider if it was generally... i.e. (control Panel\Hardware and Options of Sound\Power)

  (3) my laptop would not recognize an external monitor.

  How I solved the problem:

  1 > pass.

  http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-95107-1 & CC = in the & DLC = in & LC = on & os = 4063 & Product = 4253423 & sw_lang =

  and go to the graphics driver and download the graphics driver and follow the directions. At the end of the installation you will be asked to restart the computer.

  0nce you have restarted your computer, you should be able to adjust the brightness of the screen using the fn keys or the brightness slider in the window 'power Option '.

  2 > Activting 2nd monitor

  Click on Device Manager... At start-> right click on 'Computer' and click 'properties '. Click on "Device Manager". Now click on "monitors".

  Now connect the exernal monitor to your laptop while watching where the monitor icon appears under "monitors". It should appear as 'Generic PNP monitor'.

  Now, right-click on it and select "update driver software... "then search automatically for updated drivers. Install the new drivers. You should see the generic 'PNP monitor' name change to another name.

  3 > restart your computer. You should find that after doing all this, you should be back to normal.

• AT200 - drop in brightness problems

  Hello world!

  Recently, I noticed that there is a problem with the brightness of my Tablet (AT200-100).
  When I use it for a while, the brightness begins to fall down by itself.
  Not because of the 'auto' function, because the ambient light continues to be the same.

  The problem is that the "brightness" that I can select continues to fall down, until it reaches approximately 10%! After that, I can not select again more than 10%, the brightness slider does just not go right, so I can only choose from 0% to 10%.

  As I saw that, I saw in the 'quick-settings-clock-menu"how the brightness slider was falling down and down, without being able to restore it to its original position.

  After a while (a long time) with the suspended shelf, I can choose the brightness once again without any problem...

  Moreover, recently the Tablet starts to become much warmer before, or at least that is my impression. Maybe the heat is the cause of the problem?

  Everyone is having this problem?
  I'll try to start to uninstall apps, just in case one of them is the problem.

  Any idea oder?
  Thanks in advance!

  Hello

  Unfortunately, I m not AT200 owner therefore cannot share my experience with this device, but it would be interesting to know if one of the installed app causes this problem
  Would be interesting to know if factory reset would solve this
