Screen on Touchsmart suddenly half as bright

I have a Touchsmart 600-1100t MFG # AZ225AV. OS is Windows 7 Tablet PC 64 Bit.
I have had it for several years and love it. Last night while playing a CD in Windows Media Player the Display just suddenly went dim. It is not that I can't see what I am working on...but it is only about half as bright as normal. I have tried re-starting several times and nothing has changed. I checked the display settings in the Control Panel and I can find nothing that deals with screen brightness. I have gone through the manual and looked at all the buttons and find none that deals with the screen brightness.
Any suggestions?

Hello michaelfram.  I understand you're wondering how to change your screen's brightness.
Have you tried adjusting the manual brightness/contrast settings that are in the menu on the front of the monitor?
There are also a few settings within Windows which may be helpful for you.  Take a look at the two articles I linked to and let me know if they help.
Adjust your monitor's brightness and contrast.
Calibrate your display.
I will keep an eye out for your response so that I'll know whether this helped resolve your issue.  I hope you have a great weekend!

  • After screen replacement, top half of screen starts by looking normal but then fades to black while bottom half stays bright but with images blury. What might went wrong?

    A friend recently gave me their old Macbook pro 15 because they broke the screen and the Apple store quoted them $500-600 to fix it. I looked online and bought a screen of ebay for $170 in hopes of fixing it myself. After getting the screen I hooked it up using the steps I found online. Sadly when I turned it on, the top half of the screen was working apparently normally, but then it faded to black. The bottom half stayed bright with color the whole time but the images were always blurred. When I close the screen with it on, then open it after turning the computer on, the top half lights up with my desktop images as if it is working fine but then fades to black. The bottom is still blurred the whole time. What all could be wrong? Display cable, Inverter cable, not registering the screen or something, the screen is bad? I don't now a ton about all this and I have learned most of what I know from online research. I am not sure if I should send the screen back or if there is another issue. I just want to fix this thing.

    Unfortunately, you don't even know the lower half of the computer is working properly, because you didn't have it until after it had been abused. So forget the attached screen for the moment. Connect an external monitor to it, fire it up, and see whether you can get a usable image on the external screen. If you can, send the defective "new" screen back for a refund, or replace the LVDS video cable first to make sure that's not where the problem lies, and if it isn't, then resort to sending the screen back. If you can't get a good image on the external, give the junk machine back to your friend and walk away.

    Wow!  I think I had this same issue just last night.
    I was cleaning my macbook pro retina on the outside.  Then I opened it up and was wiping dust off the monitor and I can't pinpoint exactly when, but the colors changed suddenly.  It looked super strange, it was like green halo's and it looked worse when looking at it at an angle.  Of course I took no pictures!!!  I was freaking out that my 2 grand laptop was busted and I somehow removed a protective film or something.
    But I digress...  The image looked very green and spacey, it was almost a neat effect.  After about 5 minutes it started to look a little more digital though.  There were straight lines of this halo effect on the edges and top.  After about 10 minutes it turned into a predominate issue with the blacks on screen.  I could open a web browser and it was unnoticable on a white background.  After about 15 minutes, you could only barely see the green cloud effect if you looked at the monitor from an extreme angle.  After about 20 minutes, it was completely back to normal, I almost feel paranoid like I see a halo or something strange.  But I believe that might be all in my head now.
    So yerp, lemme know what you guys figure out.

  • Images in Bridge have suddenly become much brighter than when I call them into Photoshop CS6.

    Images in Bridge have suddenly become much brighter then when I call them into Photoshop CS6. My monitor is calbrated.

    First go the Bridge / Camera Raw preferences.
    Inhere under 'default image settings' are 4 options to put a checkmark in front.
    If there is a checkmark in front of "apply auto tone adjustments' deselect it and try again.
    Otherwise select one problem file and with right mouse click menu choose 'purge cache for selection'. If this works then go to menu tools / cache/ purge cache for folder.
    If still in trouble could you provide more details about versions and OS and preferable a screenshot to clarify the problem more?

  • Why is my Apple Mail's initial screen sometimes changed to half it's regular size?size

    why is my Apple Mail's initial screen sometimes changed to half it's regular size? I'm using an iMac PowerPC G4 with OS/X 10.5.8 and Mail 3.6 (936).

    It could be remembering where it was when you last quit the program.    The Green button in the upper left forces the window to the last adjusted size.

  • My screen is only show half of the application what resolution should i use

    My screen is only showing half of the application, what resolutions should I use.
    MacBook Air. December 2010

    It depends on which model you have:
    13" - 1440x900
    11" - 1366x768
    This of course assumes you are talking about your internal display.

  • Video size during full screen show up as half the size

    I was watching a south park episode and wanted to close it. The option to get out of full screen wasn't working so I right clicked the screen which brought up a menu. Choices were Half screen through full screen and i clicked half screen. Now whenever I try to full screen it always shows up with a really small screen and i cannot change it.
    I have gone through all the options and nothing lets you control the size of the full screen so i am guessing this is a bug. Any help would be great

    Just press CTRL + 3 while in Fullscreen "mode" to enable the video size to "Fit To Screen".
    You probably pressed CTRL + 0 at some point, reducing the video size to half size while in fullscreen mode.
    Cheers!

  • HT1430 My new iPAD3 has uneven brightness on screen. Left half is brighter than right half. Any suggestions how to fix it?

    My new iPAD has uneven brightness on screen. Left half is much brighter than right half. Any suggetions to fix it or shall I go for warranty replacement?

    If restarting or rebooting doesn't resolve the issue and the device is new, I would contact Apple or wherever you bought the iPad, show it to them and if they can't figure out, ask for a replacement.
    Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

  • Screen suddenly black when brightness is dimmed

    Hello everybody,
    I encountered a very strage behaviour yesterday at my iMac (27" 2,8GHz, 8GB, mid 2010).
    Since 10 month I had the brightness of the display to maximum and no problems. Yesterday I tried to dim it to 2/3 of maximum.
    I heard a very silent tone with a high frequency (like your dimmer in the livingroom for your lights), but it was not disturbing so much.
    After some minutes the display got black _while_ i was working and moving the mouse.
    I could reactivate it by
    - going to sleep mode and waking up again or
    - moving the mouse to one of my active corners (which has the function to swich off the screen) and moving it again to the middle of the screen
    It is not predictable, but the display goes off when it is dimmed to much.
    Had somebody of you the same issue?
    Kind regards
    Reinhard

    Something i should add:
    After a call to Apple I tried PRAM and SMC reset already but this did not solve the issue.
