Mini DVI to HDMI problems...

Hey guys, I hope you can solve my problem. My late 2008 MacBook...
Model Name: MacBook
Model Identifier: MacBook4,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.4 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB
Memory: 2 GB
Bus Speed: 800 MHz
Boot ROM Version: MB41.00C1.B00
SMC Version (system): 1.31f1
...I am having trouble connecting it to my 42" Panasonic Plasma 720p. I purchased a mini dvi - hdmi adapter and plugged everything in and just got a blue screen on the macbook and nothing on the tv. I am sure that the right input was used on the TV. I also tried using the same setup on my other 32" lcd, but had the same problem with the macbook. What am i doing wrong. Should I try a mini dvi to s-video and use that or would the picture suffer. Since my tv has the hdmi, I would really like to use it...I called apple, but the referred me to the forum or pay them $50 to try and figure out the problem. The tv has 2 hdmi inputs and I tried both of them. It also has s-video and component inputs, but no vga...Please Help...

I am having an identical problem. Unfortunately, I cannot quite follow the syntax of the response to the original post. I have a Macbook 2.1 and I am trying to hook up to an LG 32LH20 TV. I got the Mini DVI to HDMI adapter and an HDMI cable at eh Apple store. Connected the HDMI cable to the HDMI IN jack on the back of the TV. They also sold me an audio cable with the 3.5mm jack on one end and the red/white AV plugs on the other end.
Once all of the cables are hooked up, it doesn't work...exactly. If I switch the TV input to 'Component', I can get the audio of whatever is running on the Macbook, like from a Netflix movie. As for video, the only thing I get is when I switch the TV input to 'HDMI'. Then, all I get is the generic Apple purple sky. The only things that I can get in the screen of the TV that also shows up on the Macbook are when I open up things like the System Preferences menu. No browsers or other apps.
Can somebody please help me further?
Thanks
PS - yes - I am a newbie to Macs, being a PC person since '96.

  • Mini-DVI to HDMI Problem

    Hi, I bought a Mini-DVI to HDMI adapter like this one: http://www.hdtvsupply.com/mini-dvi-to-hdmi.html to be able to hook up my macbook (2007 white version) to my HDTV. However, since HDMI is traditionally for both video AND audio, the HDMI channel on the TV can only output audio coming in through the HDMI cable. There is no sound, because I am only feeding video through that channel.
    To solve the issue, I purchased the following 6ft 3.5mm Stereo Plug/2 RCA Plug Cable: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10218&cs_id=1021804 &p_id=665&seq=1&format=1#largeimage. The problem is, that I am only able to play sound from my laptop on my HDTV on one channel, and video from the Mini-DVI to HDMI adapter on another, but not both audio and video at the same time. What is the SIMPLEST way to fix this? I wouldn't want to purchase any additional cables if possible
    Many thanks for your help in advance!!!

    Thanks for that. I have a Y adapter (3.5mm stereo headphone jack to RCA sound just like you said). Under input options on my TV, I can select either HDMI1 input (which gives me video only) or AV1/S input (which gives me audio only) - not both at once...Could you explain how I can get stereo audio on my TV?

  • Mini Dvi to hdmi problem, the mini dvi doesn't even plug in all the way?

    hi,
    i have a mid 2007 macbook, i just bought a mini dvi to hdmi cable, i tried to plug it in and it doesn't even plug on all the way, 1/3 of the conector is still hanging out, and it doesnt display anything anyways, nothing is detected on the macbook or the TV.

  • MacBook Pro Mini-DVI to HDMI problems - not consistent

    I have a MacBook Pro and I'm trying to hook my LG LCD up from the Mini-DVI to HDMI cable.  Sometimes the TV is recognized no problem, but sometimes the TV doesn't receive the signal, any thoughts on how to make sure the TV is always recognized?
    I saw a post once about having the macbook boot connected to the TV to recognize it, and it worked, but I think I'm missing something again because I can't seem to do it again!  I'm looking for the post but can't find it!

    Just to add, i think the cables are all in working order as when i plug in the adapter to the macbook the screen temporarily goes blue then back to normal desktop. This only happens if the cables are plugged into the back of the TV. However they two still wont recognise each other.

  • Mini DVI to HDMI problems with 46" Samsung TV

    I bought a cable with mini DVI to HDMI at the Apple store. My new TV works great with a PC laptop, but my MBA (13") doesn't seem to be sending all the info to the TV. I get some windows, but not all of the window. I think I'm dead in the water here. Any ideas?

    Hey redhead,
    I have the same setup. Try messing around with the cable, it might not be properly connecting. Mine is pretty finicky and can lose connection if it's not sitting "just right". Also, just in case, click on "gather windows" on the bottom of the display settings dialog box. Then check to see if the Toshiba settings dialog box shows up. If it does, that means the TV is actually connected but the resolution settings have not be properly set yet. So if "gathering windows" gets you your TV's settings window, change the resolution to "1080p" if it offers that. If it doesn't, just go through all of the resolutions until you find one that works/works best.

  • Mini dvi to hdmi problems - displaying my screen on my TV

    so I have an Toshiba LCD TV with an HDMI port and I'd like to be able to play videos from the internet on my TV. I have a Macbook with a mini-dvi port so I bought a mini-dvi to HDMI adapter from Amazon and an HDMI cable from Best Buy. I also have an RCA cable for audio (which works fine). After hooking up the laptop to the TV using a multitude of combinations and restarts, all I get is a flickering blue screen on my laptop when I change the TV's input to HDMI. Nothing happens on my TV screen. Any ideas on what I should do to get video? I've read I need to mirror the display but the Arrangements tab doesn't show up on the Display menu so that option doesn't seem to be available. I've messed with resolution and numerous other things and have hit a wall.
    Help please!

  • Baffled by mini-DVI to HDMI problem

    My Macbook is plugged into a LG lcd TV through mini dvi to HDMI. The Mac screen appears on the TV but without any of the icons that are on my desktop and does not change when I play a DVD or bring up photos on the Macbook. The mouse appears, but only when I move it off the Macbook screen. Anyone know if there is some easy trick I'm missing to set this up or is this as weird as it seems? Thanks.

    From Mac Help:
    To connect multiple displays or a projector:
    Turn off the displays and the computer.
    For each display you want to use, connect a video cable (and adapter, if necessary) from the video output port on your computer or graphics card to the video input port on the display. Make sure the cables are securely connected or you may not be able to see an image on the display.
    Turn on the displays and computer.
    When you connect multiple displays, they show the same image (called “mirroring”). With some computers, you can also set your displays to extend the desktop, so a different section of your desktop is shown on each display. You can change this setting in the Arrangement pane of Displays preferences.

  • Mini DVI to HDMI problem, won't play DVD movie full screen on TV

    I use a mini-DVI port adapter with a DVI to HDMI cable to a 32" 1080p TV. When I play the DVD player screen on the TV and select full screen mode, the screen shifts back to macbook and displays full screen on the mac and the TV displays a black looking background. This issue only started after installing Lion.

    Thanks for that. I have a Y adapter (3.5mm stereo headphone jack to RCA sound just like you said). Under input options on my TV, I can select either HDMI1 input (which gives me video only) or AV1/S input (which gives me audio only) - not both at once...Could you explain how I can get stereo audio on my TV?

    Not sure that I have selected the correct forum.  Hope my questions are clearly stated.
    Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter.  TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices).   It does not show Mail or Safari menus.  System preferences'  display "gathered" the Samsung and chose its resolution.  I did not find a way to select the Samsung as my display.
    In addition to having old hardware, we have Verizon FIOS providing internet and TV access.  Is there any way to make this work for us?  We would like to stream video (Netflix) and view shows from the Web.  Do we need Apple TV to do this?  Or is it not possible with our old iMac?  My husband thinks that our Airport could be a factor. 
    Thank you

    Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
    There are, actually, many alternatives to choose from than just from a Mac.
    You need to have or invest in a WiFi capable router for all of these examples.
    Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
    If you have a older Mac, like I have noticed many users do, then you have other options.
    If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time,  you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
    These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
    Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
    Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.

  • Mini DVI to HDMI Cable problems

    So I bought the mini dvi to HDMI adapter off of Amazon so that I could connect my Macbook to my HDTV. I have seen other posts that said that this cable works but when I tried to connect my computer to my TV nothing came up. I tried restarting it and reconnecting all the cables but it still didn't work. The one time time it worked, just a blue background came up but nothing else showed up. Is it something wrong with the cable or is do I have to configure something with my computer?

    My TV is a Samsung DLP Model # HL-85887W. I do know that it does allow a computer to be connected to it because I can connect an iBook to it. The iBook doesn't have a mini DVI port and has just a normal DVI one and I use a DVI to VGA adapter to connect it to the TV. Is it possible that the TV is programmed to the iBook and I have to do something with the computer and/or TV? Or is my mini DVI to HDMI adapter faulty?
    Thanks!

  • Having a problem with mini dvi to hdmi.  Can see the background, but must move all screens all the way to the right to see on tv.  Any solutions?

    I'm having an issue with setting up mini dvi to hdmi.  I can connect and see the background picture from my macbook (approx 4 years old) but in order to see any screens or video, I have to move the screen almost all the way off the macbook display to the right.  Any ideas why this would happen?  Also, there is no audio, although when I bought the adapter and cable at the Mac store, they assured me it would handle both.

    You have the display set in Extended Desktop mode. In System Preferences>Displays on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will makethe second monitor your main screen. You can now use your MacBook in ClamshellMode with a wired or Bluetooth keyboard and mouse.  http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
    Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box.
    No Mini-DVI adapter can carry audio. The only MacBook that sends audio is the Mid 2010 model 7,1 through a Mini DisplayPort.
    If you connect the MacBook using a Mini-DVI to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo system for audio if your TV doesn't have separate RCA input plugs for audio with the HDMI plug. The Mini-DVI to HDMI doesn't carry audio and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.

    Yeah, I'm having the same exact problem - It seems that the thunderbolt minidisplay port is only able to output the analog VGA signal, not the digital signal to support DVI and HDMI. This is a bug that came up after installing 10.7.1. I bought my macbook air with 10.7 on it, upgraded it to 10.7.1 as soon as I got it, so I have never been able to use hdmi or dvi with my macbook air. This is an extremely frustrating problem for me, I used HDMI on a daily basis with my PC. I have spent many hours at the genius bar running diagnostic tests so Apple can get as much information as possible to create a fix for this problem. I have been emailing tech support for 3 or so weeks now, they keep saying that they are working on a fix and it should be out soon, but 10.7.2 has come and gone and I still have no HDMI functionality with my MacBook Air!

  • HDTV won't  display as mirror or extra display via mini-dvi to HDMI

    Hi
    I have a MacBook running 10.5.7 connected to a 1080P-capable Toshishba TV (model 42XV555). I also tried this with 10.5.6 with same results.
    They are connected via a "shuttlez" mini-dvi to hdmi dongle and then via a "wegi" hdmi to hmdi cable.
    The TV has three HDMI inputs, one designated for computer input via HDMI with a separate input for analogue sound.
    THE MB recognizes the TV and displays a separate Toshiba-specific control panel with display control panel is up. It defaults to 1600x90 and 60Hz. The Macbook adjusts every time the tv is connected - there is communication - flashing screen, MB screen re-adjusts.
    S-video works fine, via mini-dvi to s-video donglr, then svideo cable.
    It has worked twice with the MB and connected with HDMI - just twice. I have spent hour after hour tweaking resolutions, re-booting, changing cables, HDMI ports on the TV etc! When it worked I could mirror and use the screen as a separate, larger display. It worked in clam-shell mode too.
    My question is - are there any know problems getting this combination to work (ie MB, mini-dvi to HDMI)? It can work but I am missing some knowledge on the exact combination required.
    What are the optimum settings to have this TV display HD from the MB, or come to that any HD 1080p-capable TV??

    I'm attempting to connect my MB to a plasma 50 inch Panasonic TV, and am about to purchase the necessary cables from www.monoprice.com.
    I've discovered so far that the HDMI connection directly between the MB and the TV (using the appropriate mini DVI adapter of course - product # 4852 at monochrome.com and an Apple HDMI cable which I'll return to get a better price at monochrome) transmits only video/pictures but not audio.
    So far, an old, short RCA (red/white) 2-way audio test cable (again using the appropriate adapter to connect to the headphone jack on the MB) does not transmit audio directly to the TV.
    1) Could audio be transmitted from the MB to the TV using a "Coax (RCA) to Optical Toslink Digital Audio Converter" (product ID # 2947 at www.monochrome.com) to connect directly to the TV (in which case, what digital audio cable would I need to connect the converter to the TV)? And if so, would it be stereo or mono?
    OR...
    2) Should I wait until I get my Onkyo surround sound system (later this week) to see if the RCA cable will transmit directly from the MB to the sound system?
    Thanks.

  • My Mini-DVI to HDMI to TV connection stopped working - tried everything

    I have been using a generic mini-dvi to hdmi dongle plus a HDMI cable to connect my white intel imac to my television. It has worked great and flawlessly until very recently. Now the TV says "no signal". Screen still flashes blue when dongle is plugged in/out. Flashes blue when TV turned on/off. Nothing was changed in my setup. I have tested the mini-dvi port with the Apple Mini-DVI to S-video/video dongle (worked), tried a new minidvi-hdmi dongle (fail), tested the HDMI cable (good), and tested other ports on the TV, as well as resetting the TV to defaults. Still not working.
    At this point, I was assuming it was a software problem, even though starting from a restore disk or in safe mode did not solve this. Could this be a software issue? Is my video card only doing analog signals? My TV is less than 6 months old, so I doubt its that. Any advice would be greatly appreciated. I usually can solve these things myself, but this time it's vexing me. Thanks.
