Settings for monitor using thunderbolt to vga cable

Have an HDTV  Bought a cable for thunderbolt port on macbook pro to vga. Hooked it into vga port on tv, and got backgound screen saver, but no icons or menus on tv. What settings do I need to change?

None. Just drag windows off one edge or another of your built-in screen to move them onto the TV set.
The TV is in Extended Desktop mode, meaning it serves as an extension of your built-in screen's workspace. In that mode, the TV and the built-in display can each operate at its full native resolution and you can have different stuff on each of them. In the alternative mode, Mirrored, the TV will be limited to the maximum resolution of the built-in display, which is lower than the TV's unless you have a 17" MBP, and both screens will always display exactly the same stuff. Because the TV will have to operate at less than its full resolution in Mirrored mode, it will always be blurry in that mode.

  • Strange issue with external monitor, only working when external speakers plugged in (using Thunderbolt to VGA adaptor)

    Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
    I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
    To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
    What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
    Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source.  What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
    Some other information:
    - Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
    - If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
    - The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
    Any information would be great – am I missing something here, or is this genuinely weird?

    Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
    Here's what I did to test:
    Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured.  I transferred onto their machines, hooked up my Sony D8, and attempted to play the video.  It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop).  I even tried changing each machine's firewire driver to the legacy one and same results.  I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
    I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver.  Very annoying.  I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
    I have 2 other things I can try:
    1.  Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
    2.  Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/).  I can't do it with my Home edition apparantly.
    Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

  • HT2494 Reboot my Macbook Pro when using external monitor w Thunderbolt to VGA adapter

    I have a Macbook Pro running 10.9.2 OS X (MacBookPro8,1). I never had any problem w that but yesterday i bought an external monitor (kind of old model from LG - L1900E). Well, i was trying to extend my Macbook Pro display through a Thunderbolt to VGA adapter. It worked at first but it started rebooting my Mac. I just disconnected that and the reboot stopped.
    It sounds to me like a Software related BUG regarding connection or something strange.....
    I would like to have some help on how to proceed w that ? Is there a specific SW i need to install to use that ?
    I am kind of disapointed because i heard that one of the major items the new OS X was about external displays.....
    Looking forward a help from an apple specialist, Tks !

  • Settings for monitoring Solaris CPU and memory using ATS serverstats

    Hi,
    I need to set up some monitors for a Solaris 10 server (hosting Web server for Application Under test) using OLT. Can someone please advise as to what set up I will need to access the Solaris CPU/Memory/vmstat data during the performance tests?
    Do I need to install something on the server side? What user priviledge will I need to access this monitor on the Server and what ports should I open?
    Regards

    Hello
    Nothing to install. It's completely remote using ssh or telnet. (so standard ports to consider).
    You need to setup what we call a "virtual agent".
    Create a "monitor" using "Virtual Agent" as a data source.
    Then you need to setup your remote system and particularly to configure the prompt returned when logging in with the given user (try manually with plink first).
    Then you can try predefined metrics which are not so good in my opinion. So better to create your own metrics. (find the proper unix command line to retrieve the information needed and use regular expression to get the value out of the output.
    Pls first, you should update plink.exe in the c:\oracleats dir (don't remember where) by downloading a newer version on internet.
    I'm sure it's not all clear, but with the documentation, google & some effort, you should find the solution.
    Cheers

  • How to connect imac to tv using thunderbolt to hdmi cable

    I'm trying to connect my mid 2011 iMac to my tv. I have a thunderbolt to hdmi cable that I purchased. I connected the thunderbolt port to the iMac and connected the hdmi port to the tv. I turned on both devices and the tv is not getting the signal. What am I doing wrong? Any help would be greatly appreciated!

    If you open the Displays preferences and do not see an Arrangement tab (or there is an Arrangement tab that shows only a single monitor) then there is something physically wrong with your connection.
    Although I don't have thunderbolt, since you can plug mini-displayport into a TB socket, then like mini-displayport, they a a little sneaky in that you need to make sure the plug is fully seated in the socket.
    If you do have an Arrangement tab, and it shows two screens, then click detect displays.  Then click Gather Windows to bring the TV's Displays preferences on to your main screen.  Set the proper resolution (probably 720p, 1080i, or 1080p).  Set the refresh rate (probably 60Hz).  You should see a picture at this point.
    You may have to play the underscan/overscan settings on your TV and the displays prefs for the TV if the picture is too small or larger for the TV screen.
    Also, you need to set your Sound preferences to output to the HDMI connection.

  • Settings for optimum use for MBP / Dell 27"

    I recently purchased a Dell 27" monitor (which is lush to use for my MBP main display and xbox360 etc.
    The MBP display is 1680x1050 but the dell display is 1920x1200 meaning i have to down-rate my display otherwise i have a big blue band around two side of the dell display.
    Therefore im not using the display at its optimum settings.
    Can anyone over any advice or should i look at purchasing a new laptop capable of displaying the 1920x1200?

    Hi Phil: With the external monitor connected, go to System Preferences > Displays >Arrangement Tab. You will no have 2 separate windows for monitor settings. On the one with the "Arrangement" tab uncheck the Mirror Displays box. You will be able to set each monitor to their native resolution. To utilize the external monitor, just drag any open program/application to the external.
    Hope this helps

  • How do I restore the settings for apps using Time Machine?

    I believe there are problems with items within the Library Folder inside the System Folder.  For example, there are two "Frameworks" Folders, but one has "(from old Mac)" after its name.  I dare not try to remove or even move either.
    Back in the day of OS 9, you could modify something, then search for it by "Last Modified" Date, and find where Apple has hidden itscontents.  It's not so easy in OS X.  I've had some success using Pondini's Time Machine FAQ's, though.  Here is how I got to this problem:
    Our family MacBook died.  After getting a repair estimate of $500 to $700 "if it's the Logic Board," we decided to replace it.  We purchased a MacBook Pro running Lion.  (Later, we brought it to an Apple Store and were quoted $435 in house or $280, but they would have to send it out.  Incredible repair: Logic Board, Top & Bottom Case, Super Drive, Battery, all for $280.  No wonder they're #1).  I pulled the Hard Dive out, erased it, and installed an older operating system, but during the repair they installed 10.6.
    Restored the MBP from the TM backup of the MacBook. OK
    The Macbook is repaired and the store showed me how to restore the data from the TM backup.
    Restart and the passwords do not work due to restoring a 10.6 machine from a 10.7 backup.
    Tech support guides me through resetting an admin password using the password utility on the install DVD.
    changed the other passwords inside of Accounts in System Preferences.  Then changed the password or the other Admin.
    Restart, get a circle with a line through it.
    Tech support guides me through fixing this.
    Restart, half my Apps do not work.
    Tech support says to re-install 10.6.
    I did but I thought it would erase and install but it just re-installed 10.6.
    Most Apps work, except iPhoto.  Mail is OK sending but only receives on one of 3 accounts.
    Is there a fix for iPhoto & Mail?  If not, I would plan to erase and use the finder to drag the user folders from TM to the MacBook.  Can I just drag the Apps too?  How about all of the settings for those Apps?

    If you don't keep a backup, you can't restore your machine to any state except the state in which you received it, brand new, with none of your own stuff on it. That makes a pretty convincing argument for backing up, doesn't it?

  • I can not connect to projector using Thunderbolt to VGA adapter

  • How do I access my raw settings for further use?

    I opened a jpg in CR, made some changes, opened the image, then saved (from within PS) and closed it.
    Later I needed to create a duplicate of this image and apply the same CR settings I'd used, but I can't find them. When I open the original jpg, all of the CR settings are set to zero.
    Is there any way I can access the CR settings I entered? I want to see what they are, not delete them, not get back to the pre-CR-edit stage.
    If this is not possible, what could I have done otherwise to retain access to my CR settings? Should I have saved the image from within CR? If so, how would the CR settings be availalbe for tweaking or copying?
    Is there an automatic xmp file that would have this info, and if yes, where would i find it?
    Finally, how do I save CR settings in the future for subsequent access?
    Many thanks!

    The xmp data is written into the original jpeg file, not a sidecar file.
    Here's the drill (I'm doing it as I write this msg):
    1. Select a jpeg in Bridge.
    2. Right click on the image and select Open in Camera Raw...
    3. Perform an edit (I did a drastic exposure reduction to make the edits obvious).
    4. Click on Open Image, comes up in Photoshop with edits.
    5. Shutdown PS and Bridge.
    6. Re-open Bridge, select and open same image.  Opens in Camera Raw automatically, shows edits, and new CR settings.
    As I stated in my earlier post, the only way to "de-Camera Raw" the jpeg image is to clear settings from within Bridge.  Again, the jpeg is being re-written with the edits within the file as exif data.  And no, there is no message that such a re-write is occurring.

    Absolutely. The system just won't be taking advantage of the speed that the Gigabit adapter is capable.

  • Best settings for what used to be HDV, became M2V?

    I have some concert footage I shot in HDV60i (on a Canon HV40). I only exported it to DVD and not to an HDV file, so all I have now is an M2V file and an audio file (AAC). Now I need to upload it to youtube, but I have to do some editing in FCP6 first. What is the best sequence settings for me to use in FCP? My second question would be how should I export it for best viewing on youtube (since it's no longer a true HDV file), but that question may be better served for the Compressor forum...any info would be appreciated though!

    hi,
    well a lot depends on the footage you might be using. Use the setting that matches that. Or if its graphics based use the biggest baddest HD setting you can. Of course if the finished thing is getting burnt to a DVD to be shown its all going to be compressed then and lose quality at that stage.
