  • Premiere Pro CC - program monitor displays only a black screen

    Hi all

    I hope there, can someone help me (and I'm sure many others) with this problem.

    I used the first Pro CS6 and was at Midway through a project when I upgraded to first Pro CC. It was very good and I finished the project, however shortly after this when I re-entered Premiere Pro CC to make some final adjustments and settings, the program monitor seems to be black. I see nothing but black on the monitor of the program window. When I play the project, the sound works fine, but I don't see anything in the program monitor.

    Please see the discussion linked here (http://forums.adobe.com/message/5487954) for more information on this issue. I'm hoping to turn the heat on it and get answers for everyone having this problem. She made my first Pro useless right now. I can't yet start new projects because it has the same problem.

    NOTE: I tried to roll back the CS6, but it does not work and I discovered this forum that roll back versions has never been possible. I also tried to reinstall CC PP but that does not solve the problem.

    I hope someone can help here.

    Thank you!

    I hope never auto-updates for nothing! I went to Nvidia.com and found a driver for your 5200M last month, try this - http://www.nvidia.com/object/quadro-notebook-win8-win7-64bit-320.49-whql-driver.html

  • Dell Inspiron M5030 black screen when installing Windows 8.1 on 'Get Ready devices.

    Dell Inspiron M5030

    I had Windows 7 installed and works perfectly, but I wanted to install Windows 8.1, I tried a new install first (also tried to upgrade to windows 7). Everything installs fine but when it restarts for the first time the windows logo appears and 'Getting devices % ready' then the screen goes black.

    Ive tried:
    -For let sits for awhile to see if it comes back, and I get nothing after hours
    -J' plugged a monitor without response (also tried to close the cover put to sleep and go to bed)
    -J' quit and tried to start in Safe Mode, but it says that Windows cannot boot mode safe because windows setup has not finished

    I can start on my windows repair and go to the recovery prompt but don't know what to do. It looks like a video driver issue, the laptop has an AMD Radeon HD 4200. If thers any why to install the driver before implementation ready devices? Help, please!

    I had the same problem and did this and it worked without problems... The idea is to integrate the drivers updated in the ISO/DVD. The drivers supplied with the W8.1 DVD do not work as well as I was getting the BSOD with the installation.

    1. download Winreducer and install all the 3rd party software that it requires.  Look in the howto.pdf

    2. download the latest AMD Catalyst drivers from AMD website (not beta).  Drivers Windows 8, I think that the list.

    3. extract the files to temp dir.

    4 copy files and drivers since the temp (packages\drivers\display\w86a_inf) directory and the sub (B149756) to the dir dir drivers winreducer (work\integrate\drivers\x64).  In the x 64 dir, you should have cats, msi, INF and the b149756 files.

    5. run winreducer.  Make sure you have practice an iso to DVD Windows 8.1.

    6. Once you mount your iso, you will spend for options and features screen.  You can see the presets, appearance, features... on top.   Let alone all the options EXCEPT the location of the drivers under System.  Change this to x\WORK\INTEGRATE\DRIVERS\x64.  Don't forget to change the x to your location.

    7. click on finish.  Save as an iso. Apply.  It will save the iso changed in the winreducer folder.

    8 burn and install.

    9. After you are done installing, install the driver package that you downloaded in step 2 by running setup.exe in the main dir.

    10 thank me LOL

    It worked for me on an Inspiron M5030.  I hope that my answer is detailed enough.

  • Canon G12_I cannot take a picture. Purple lines fade in and out, then black screen.

    Uploaded a few photos off the G12 and then charged the battery and when I reinstalled the battery I could see pictures, but when I switch them to camera mode I have brief purple lines then black. And I'm not able to take pictures. Help!

    Uh oh, sounds like the processor or sensor could have retired. I have to assume that you can not access the menu to do a complete reset of the system, so I remove the battery and try to keep about an hour. With the battery, press the power button and hold for about 10 seconds. Then, reinstall the battery and see if it does the same thing. If so, you may need to contact Canon on a repair, but that could be very expensive. It could have been a static load that occurred when you changed the battery, otherwise the processor or the sensor has reached the end of the line.

    I feel your anxiety that I have a PowerShot G12 and this is my favorite camera. It is used there, and some refurbished, to replace it. I hope you can get it running again.

  • monitor gets black screen

    My monitor guard rethink a black screen when I turn on my computer, basically when I turn it on I see start for half a second, then I get the black screen while my monitor is always on

    Now, I recently built a computer, put it a few days ago the same thing happens, I didn't install anything don't not even windows 7 yet, but when I turn on the computer I get the black screen again, I can not install windows

    My brother and his friend think it is the graphics card, but when I built my new computer black screen continued to occur. If I turn my screen I can see my screen for half a second, and then it just goes black again.

    So I was wondering... What is the cause of the problem? my brother think that theres something wrong with the new parts, I think it's the monitor that is causing the black screen and I have to buy another... What is it?

    Hello

    Since the monitor displays the same black screen after connecting to a laptop, this might be a problem with the monitor. Contact the manufacturer of the monitor on this issue.

    This is a pic of many others like this and I don't know why, if the monitor can work very well most of the time and open this own photos minimize mode just do not touch the edge of the screen

    Once it not closed, that's what's going on cause the problem.

    What's causing this problem?

    (function (id) {var v = document.getElementById (id), isSafari = navigator.userAgent.indexOf ('Safari')! = - 1 & navigator.userAgent.indexOf ('Chrome') ==-1; var op = v.style.position, ol = v.style.left, or = v.style.right, fe = []; var nodeLimit = 50; checkVideo = function() {if (! v.canPlayType | v.error) {var bound = 0; while (v.childNodes.length > 0 & bound 0 & linked A.parentnode.removechild (fe) ;}} else {window.setTimeout (checkVideoRendered, 249) ;}} if (navigator.userAgent.indexOf ('iPad') ==-1 & navigator.userAgent.indexOf ('iPhone') ==-1 & navigator.userAgent.indexOf ('iPod') ==-1) {window.setTimeout (checkVideo, 249) ;}})}})}}}) ("v_5a7bac2671f94699a46e104042386e5f");

  • Application of monitor Dell DDM with U2515H and U2412M dual screen setup and USB drive menu

    Hello

    I have U2515H and U2412M independently connected with DP cable to GTX960 video card.

    Two questions;

    1.

    I have the latest driver display and the last Application of monitor Dell DDM.  It detects U2515H OK but not U2412M.   necessary on the menu OSD is activated but still no go.    Is - this known issue?

    2.

    Also with U2515H, curiously section USB tab energy on screen Menu (the one who press the button) is grayed out.  Can not choose how the power of USB hub behave when the screen goes into sleep mode?    What cause this menu to be grayed out?    Factory reset has no effect on this menu item.

    Be aware that U2515H has been replaced by Dell last Friday with monitor construction January because the one originally, I got a defect on the bezel mounting, but this USB menu was selectable.   It was built in April/205.

    Thanks for the research.

    (Updated the model type edition only)

    There is no U2414M. Do you mean the U2412M? If so, the U2412M is not supported. It was an error in the web. DDM requires a year of Dell 2013 model year or newer.

    There is no U25125H or U2525H. Do you mean the U2515H? From the U2515H Manual page 41 =
    USB
    Allows you to enable or disable the USB function standby monitor.

    NOTE: USB power standby mode is available only when the USB upstream cable is disconnected. This option will be grayed out when the USB cable upstream traffic in.

  • Why my laptop screen is too dark? I have a Dell Inspiron.

    Why my laptop screen is too dark? I have a Dell Inspiron. How can I brighten it?  It is 2-3 years and is connected to the power supply. He has suddenly dimmed. I can hardly read.

    At startup, the power of type in the box above.  Choose power options.  Check the brightness settings here.  On the battery, they should be lower.

    There are also keys to the top of your keyboard, which can affect the brightness.

    If there is no problem, you probably have a hardware problem, which may not be easy or cheap to repair.

    Read the installation instructions on the Web site where you get the drivers.

    To find out what hardware is in your computer:

    1. read all documentation that you got when you purchased the computer.
    2. If the computer is OEM, access the site Web of the OEM for your specific model machine and look at the specs (you'll be there to get the drivers anyway)
    3. download, install and run a program of inventory of the free system like Belarc Advisor or System Information for Windows.
