Erratic track pad behaviour when connected with lcd tv thru hdmi

hello all..
i have a 3 week old mbp with lion preinstalled. i tried connecting my JVC LCD tv to it using HDMI. as soon as i get the projection of my desktop
on the tv, the trackpad starts its erratic behaviour. it just starts jumping around and sometimes randomly my mission control page comes.
but, as soon as i disconnect the hdmi, every thing comes back to normal..!! i tried smc reset and voila !! hdmi works perfectly...
this was yesterday... today i have the same probl all over again...i cant reset the smc every now and then to connect my tv thru hdmi ?
please help thanx

It's bluetooth interference from the monitor as described here:

  • X1 Track Pad issue when used with ultraslim powersuppl​y

    This is a really strange issue,  Anyone else having it?
    X1 I5 160Gb SSD 8Gb Ram  Mix it with a Ultra slim PSU (41R4538) and the track pad starts playing up intermittently.  Unplug the PSU and it works fine.  Use the native PSU and it works fine.       Do you think I have a faulty PSU ?
    Best regards

    Well I got a replacment ultra slim power supply and I have exactly the same issue.

  • Please, i bought a new track pad for my imac. it is working well when my imac is on. But, anytime i off my imac and wish to on it again, My track pad will be connected but it doesn't click i will need a mouse to log in my password first . Any help?

    To be specific. I have the imac late 2013 model, and i just bought the trackpad this October 2014. I have been using magic mouse without any problem. I just want to have a new experience with the trackpad.  Any time i on my imac, i will have a normal screen with my picture and a guest column at the center. I need to click either my picture or the guest in order to have the space where i can key in my password with the keyboard. But unfortunately, my trackpad will show that it is connected and the cursor will be moving in front of the screen if i touch the trackpad, but if i try to click, i will get no response. I have to put back batteries inside my magic mouse and then click on my picture if i want to log in with my id or i click on the guest image if i want to log in as a guest. it is only after this that my trackpad will start responding.
    i want to use only trackpad for now so as to be more efficient with it. I don't want to be putting back batteries inside the magic mouse only to on my imac. I need a solution please.
    Thanks.

    It sounds like you have assigned the primary click on the trackpad to something else, perhaps a gesture.
    Use your mouse, login and then open the Trackpad preference pane and see how you have the interface configured.
    Oh and you can have both the Magic Mouse and Magic Trackpad powered up and working at the same time. No need to keep moving batteries around.

  • My iPhone 5 got problem when connect with lighting cable, this will keep pop up message "this accessory may not be supported"

    My iPhone 5 got problem when connect with lighting cable, this will keep pop up message "this accessory may not be supported", I can't charge or sync at all. I tried plug and unplug many time, still can't detect/charge my iPhone5, but sometime will 'lucky' that can connect to my iTunes and charge battery…
    This message will auto pop up also when I don't have plug anything in my iPhone 5, It is very annoying…
    The lighting cable is original and now i'm using OS 7.0.4 / iTunes is 11.1.3
    What I can do to fix this problem? Thank you.

    I would try using another cable you can likely borrow one to test from somebody
    if it's the same then likely the connector in your iphone have been damaged

    my samsung says video out from i pad is not supported. i am connecting with apple dock using hdmi. I do get the audio  any suggestions?

    Jeffrey-
    If the HDMI input to the Samsung is not compatible, does it have a VGA or composite input?  I have both the HDMI and VGA adapters for the iPad, which work with the small Vizio HDTV I tried.  I understand a composite video adapter is also available.

  • Why can't I zoom in on text with my track-pad like I can with other browsers? I have a MacBook Pro. I used to be able to pinch and expand pages but now I can't.

    Why can't I zoom in on text with my track-pad like I can with other browsers? I have a MacBook Pro. I used to be able to pinch and expand pages but now I can't. I have bad eye-sight and really enjoy and NEED this feature to be able to read most sites.

    Hi dwightfontenot-
    Some gestures have been removed in Firefox 4 and later.
    You can restore the zoom feature by changing the values of the related prefs on the about:config page.
    browser.gesture.pinch.in -> cmd_fullZoomReduce
    browser.gesture.pinch.in.shift -> cmd_fullZoomReset
    browser.gesture.pinch.out -> cmd_fullZoomEnlarge
    browser.gesture.pinch.out.shift -> cmd_fullZoomReset
    browser.gesture.pinch.latched -> false
    To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
    If you see a warning then you can confirm that you want to access that page.
    Use the Filter bar at to top of the about:config page to locate a preference more easily.
    Preferences that have been modified show as bold(user set).
    Preferences can be reset to the default or changed via the right-click context menu.

  • When connecting with FaceTime, I see other people then they hang up.

    When connecting with FaceTime, I see other people then they hang up.  Has anyone one else encountered this?
    Usually, my wife contacts me with facetime, I try to accept connection and she sees other people form another country that quickly hang up.
    This happens often.
    Thanks

    This seems to happen with the Iphone 5s if I am not mistaken

  • Can't open app store in itunes when connected with ipad

    Hi. Could anybody tell me how I can use app store in itunes when connected with ipad 2? When I click app store, it just gives no response at all. Thanks a lot!

    Welcome to the Apple Community.
    Do you have the power cable in, it won't show up with the power cable in.
    Additionally, there have been some issues with the update servers, it's possible you won't be able to complete the update procedure anyway.

  • Why isn't my iPad2 charging its battery when connected with my iMac?

    Why isn't my iPad2 charging its battery when connected with my iMac?

    A lot of computers, especially older ones (I don't know how old yours is), don't provide enough power through their USB ports in order to charge the iPad - it may still be charging, but at a low rate (it may charge quicker if the iPad's screen is off). If you want to charge it at a reasonable rate then the wall charger is better.

    Hi!
    It looks like there might be some security settings or software on your laptop that's preventing the restore process from working.
    Check out this article in Apple's support. It shows you the steps you can take to try to get around error 1611.
    Like diesel vdub said, a DFU-mode restore might give you success where a regular restore might not, so maybe you can try that.
    What you need to do is put your phone into DFU mode, which is a low-level mode that helps the restore process get a little more done, or it can help iTunes get around certain roadblocks (hopefully like the one you're experiencing!). Your computer will install special DFU-iPhone drivers for it, and then iTunes will see it as a phone that needs restoring.
    To get your phone into DFU mode:
    Plug your phone into your laptop.
    Turn the phone off.
    Press and hold the power/lock button. Keep it held in, even after the display turns on and you see something on the screen. As soon as you see something on the screen, start holding the home button as well as the power button, so that they're being pressed together.
    Keep both buttons pressed down for 10 seconds.
    After 10 seconds, release the power button, but keep holding home until the laptop sees a new USB device. Once you see that, you're in DFU mode, and you can let go of buttons. Your iPhone screen will be blank during it all, even though it's actually on, in DFU mode.
    Now your restore should work!
    If your phone shows the Apple logo or anything else while you're trying to get it into DFU mode, then something went wrong. Try the steps again. If it suddenly starts up normally again, try reducing the time to a bit less than 10 seconds--try reducing it by about a second at a time. It should work!

  • Since upgrading the IOS 8 on my IPad 2 I can longer get a full screen on my TV when connected with an HDMI cable. anything I should change in my settings? Right now my iPad is mirrored on the TV with a black box all around the edge

    I have reached the same conclusion in the mean time. I have done a bit of investgation in to other grahics cards and am seeing some that show SPDIF connections from the card to the mother board. I was not familar with SPDIF but it did a little bit of sluething. It is of course a digitally enconded voice. I am guessing that in that case the mother board ( assuming it supports this hardware option) would use this output and be able to translate that digital audio to its other audio outputs. That is a lot of guessing of course. I think my "solution" might  be a whole new desktop - a rather drastic course of action! I was in the proceess of getting ready to upgrade this machine anyway with a new graphics card (which I will now return), go to Win 7, and maybe even a new digital TV reciever,  and I don't want to throw good money after bad anyway.
    Thanks for your comments

  • Will not recognize the Lucid LG when connected with USB

    My Dell  will not recognize the Lucid LG when connected with USB. Both the computer and phone gives a split second prompt that they are connected but then goes away immediately.  After reconnecting it several times however it will finally recognize the mass storage. How can I get away from the hassle of multiple re-connections before it finally recognizes that connection?

        That's some helpful information about your issue samrmusso! Some recommendations that I have for you is to try a different USB port on the computer to see if it isn't an issue with that specific USB port.  Are you using the cable that came with the device (recommended) or a 3rd party cable (may not support data transfering properly)? You can also try restarting both the device and computer and retest. It's possible that there's a driver conflict on your Dell. Here's how to check for these types of conflicts: http://goo.gl/qH4m5 
    Keep us posted on any additional information/details about your issue.
