HDMI audio still works but only my TV displays the desktop instead of what's on my computer moniter.
Hello
Hope someone can help with this mystery. I've been watching Netflix fine until yesterday, when all of a sudden the HDMI signal has stopped working. I can put a movie and hear through television, but the TV shows a picture of my office, even if the Office does not appear on the computer, the film shows. How is that even possible? Tried turning off and unplugging everything. With the help of windows 8 (and is it to be terribly frustrating)
Hello Randy,
Thank you for giving us the opportunity to help you.
I would be grateful if you can provide us with the following information to help us better understand the issue.
- What is the brand and model of the computer?
- Did you try to connect to a different HDMI port and check if it works?
According to the description of the signal problem HDMI has stopped working. You also mentioned that you can put a movie and hear through television, but the TV shows a picture of your desktop, even if the Office does not appear on the computer.
HDMI cables are supported, but not all, audio signals compatible HDMI video audio support cards. If your TV has an audio input, you might be able to connect an audio cable separated from the sound card of your computer directly to the TV. Otherwise, you need to connect the different audio signal to an output device, such as external speakers or your stereo. Follow these methods and check if that helps:
Method 1:
I suggest to disconnect the HDMI cable and try to connect it buy, follow these steps.
a. turn off your computer and place it near your TV. Unplug the monitor, but leave the mouse and keyboard connected.
b. connect the video cable from your computer's output to your TV.
c. turn on your TV and set it to the input that matches the output on your computer. You may need to refer to the supplied with your television user's guide for instructions on how to do it.
d. turn on your computer.
e. you should see windows displayed on your TV. If the screen looks stretched, or part of the screen seems cut off, you will probably have to adjust the screen resolution in Windows.
f. If Windows will appear on your TV, you will need to reconnect the computer to your monitor and adjust the screen resolution before connect you to your TV.
To set screen resolution follow this procedure:
a. right click on the screen, and then select the Screen Resolution.
b. check if the resolution is set to 1024 x 768.
c. If this isn't the case, then set it to 1024 x 768.
If the problem persists, go to method 2.
Method 2
According to your description, it seems the question could be linked to the display drivers and try again the steps to uninstall graphics card in Device Manager, uninstall the drivers of device from the list of programs, and then download the latest drivers from the manufacturer's website.
Step 1:
Uninstall the device from Device Manager
- Open the Device Manager
- Expand the section of the graphics card .
- Find the Display card Driver.
- Graphics Driver right click and choose Uninstall.
- Select the check box delete the driver for this device.
- Restart the computer after the uninstall is complete.
Step 2:
Uninstall the drivers of device from the list of programs in the control panel
- Click Start, select Control Panel
- Now, click on programs and select programs and features.
- Find the Display card Driver.
- Display driver card click right and select Uninstall.
- Restart the computer once the uninstallation is completed
Step 3:
Download and install the latest drivers for the graphics card on the manufacturer's Web site
For more details you can see the wire supplied below which deals with the very issue that you are facing.
Hope it would help. If problem persists always post back with the current state of your computer and the result of the proposed suggestion, we will be happy to help you.
Kind regards

Research of a window does not work (but only when the folder is indexed).
As the title suggests, I can look perfectly fine and find EVERYTHING in a folder with even the most detailed search operators, but only if I index the file. I had the same problem with Windows 7 as well and I don't know how to get around this problem. I think it may have something to do with the case in question is on an external drive but I still don't understand why this is the case. Indexing is supposed to make the search faster for a specific folder, but no matter what I do, Indexing always brings Vista only returning "no matches" for each search query. If I was of the same type in one letter, he found nothing.
Assistance would be greatly appreciated.

My internet does not work correctly. I use an ethernet cable to connect my laptop (using windows 7) to the internet. However the connection is very bad. Sometimes it works but only for 30 minutes max, and other times it does not at all, connect saying that the cable is disconnected. I tried 3 different cables to 2 different ports, then maybe the problem comes from my laptop. It connects to the wifi networks fine but not with the cable. Does anyone have any suggestions as to what could be the problem and how can I solve this problem?
Hello

Here's the preview of this weird problem. (BTW, I use after effects CC 2014 on Mac OS 10.9.5.)
Step 1: Download this clip stock in the new model.
Step 2: Time reverse the clip, since that's the shot I'm looking for.
Step 3: Apply '3D Camera Tracker' and wait for analysis and camera to solve.
Step 4: Confirm a good track and choose an area target between 3 points
Step5: right click and select 'create text and Camera '.
-SO FAR SO GOOD, BUT THEN... -
Text element appears in a bad position (elsewhere in the model, many pixels away) and is not properly locked to background images, but rather floats above him like a normal 2D layer. However, if I change my display in the window of the model of "Caméra Active" now available "3D Tracker camera" view, everything looks good. I can then add other elements (text, sound, models 3D using the plugin video clip of the first officer, etc.) and they work all as expected- but only when you view the view model 'camera Tracker 3D. " Of course, if I try to, it makes on what sees the camera activates, which seems wrong.
This is the strange thing. Analysis, camera fix, etc. all seem to work well. But if I can only display it correctly in the view 'camera 3D Tracker' and not 'Active camera', then I am not able to make out successfully. I tried different tutorials on the subject and able to successfully replicate for example this one, without running into the weirdness of the Active camera. On my computer, it's a different story. Thanks for your suggestions.
Thanks again, Todd. I have found a workaround and Walter Soyka simultaneously ID had the problem - set up, they seem to be a bug in AE when followed 3D clips time-reversed. Easy enough to fix once identified and hopefully fixable in future app updates. Details here:
3D Camera Tracker works, but only in 'view camera 3D Tracker' not 'view Active': Adobe After Effects
Thank you.

autoexpanding a tree works - but only once
Heya ADF-community :)
I ran across a strange behavior in the adf (latest version) and I do not know how to debug/fix it. I put a tree on initiallyExpanded = 'true' and it works, but only once.
My scenario:
I have a splitter-split page, with a tree in the left (navigation) and 'details' separator in the right. The details are inside the same page, a blender decides which section to display. (More details )
Then. Navigate in my navigation tree, access to a node and the 'details_1' section opens and shows a part of entry fields and trees (another). This tree has the value initiallyExpanded = "true" and is initially developed.
Then, I chose another node in the navigation tree, which also highlights the "details_1" (just for another record). Iterators are defined (input fields contains the correct values) but the tree is not developed. This is the same section if the tree is the same, very, very, like work one :)
After opening some leafes and switching back and forth between the two records details the tree keeps the last State.
My tree:
I found a blogpost by Frank Nimphius, but she came back in 2007, so I don't know if this is even necessary, or an option.<af:tree value="#{bindings.MagMagTree.treeModel}" var="node" selectionListener="#{bindings.MagMagTree.treeModel.makeCurrent}" rowSelection="single" id="mag_parenttree" initiallyExpanded="true" partialTriggers="::save_mag"> <f:facet name="nodeStamp"> <af:outputText value="#{node.Name}" id="ot9"/> </f:facet> </af:tree>
Any reference to what could be wrong? A misunderstanding by myself? An error in my logic behind this? A bug?Hello
documentation of the component:
+ "If during the initial rendering, the current subtree under the path of target line should be expanded. A RowDisclosureEvent is broadcast from the encoding start component so that listeners are correctly informed of the disclosure. » +
So, if not you unload/reload the instance of the tree but simply refresh the tree, it is not considered as initial rendering. In this case, I think you have to programmatically set the dislosure line key on the path of the selected tree

I created show and hide features in InDesign I want to export to interactive PDF format. These functions work when seen in Acrobat on the desktop, but not on iPad/Tablet - why?
Why? Most likely because the PDF Viewer on the Tablet is too stupid to deal with show/hide functionality.
You could try PDF Expert of Readdle on qpdf Notes Pro on Android and iOS devices.
Depending on how the show/hide was created during the export of InDesign, it can work in viewers. Otherwise, you will need to open PDF files in Acrobat and edit features show/hide something more digests of PDF device viewers.
BTW, you will encounter the same issues with the PDF display components in web browsers.
I hope this can help.

I can't find the FF in 10 Windows anywhere... I downloaded, refreshed, etc... but no visible icon on the desktop, the icon taskbar, dosen't show at "all apps".
See if there is a Mozilla Firefox directory in C:\Program Files (x 86). If so and there are files in this directory, you should be able to reinstall Firefox without losing your preferences.
Also, you should be able to run it by typing "Firefox" at a DOS command prompt. If it is running, then just create icons yourself.
