Connecting mid-2007 iMac to LG TV via mini dvi to HDMI

I am trying to connect my mid-2007 iMac to my 42" LG HDTV to no avail. I am running iOS 10.6 Snow Leopard. I bought the mini dvi to HDMI adapter and plugged the iMac into the TV. I went to the display tab in the system settings and see that the iMac recognizes the tv. I went to the arrangements section and it recognizes the tv. When I click on gather windows it even calls it the LG TV. However, there is nothing showing on my TV. It says no input detected. When I move my mouse to the right side of the screen it disappears like it is going to a second monitor.
Any thoughts?

Hey Corinthone, did you ever figure it out? I have a mid2007 iMac running snow leopard & a 120hz LGTV 42". I was having the same issues as you(yes Frankie, I made sure I was selecting the correct hdmi input). Now with the same setup, my LG recognizes the HDMI input from my iMac. It says connecting but then 'no signal' on the screen. The hdmi2 is still showing a connection in 'inputs' just no picture on TV. I started changed the setting via my mac but still nada. The lg is 120hz. Does that have anything to do with it? Thanks

Connect Mid-2009 Macbook Pro to HDTV via Mini Displayport to HDMI adapter

Hello,
I'm trying to connect my Mac to my HDTV via a Mini Displayport to HDMI converter I bought at the Apple Store. I have tried on three different HDTVs, none of which allow me to output video. I have tried adjusting the resolution to every available resolution under system preferences. Any advice as to how to resolve this problem would be very much appreciated.
Thank you,
Jordan

I'm having the same problem, also with a 2009 13" MBP and a Mini DisplayPort to HDMI adapter. Does anyone out there have a solution? Do we need a different kind of adapter? My tv is a Samsung 720p. My boyfriend can connect his PC laptop with an HDMI cable with no issues.

IMac (mid 2007) to LG 32LH20 via mini-DVI to HDMI

Seems like this is a fairly common problem from what I've read, but I'm having some issues connecting my mid-2007 iMac to my LG 32LH20 HDTV via a mini-DVI to HDMI adapter and an HDMI to HDMI cable. The adapter and cable were purchased off of Amazon (product links here and here), but the Mac and TV don't seem to be recognizing each other - the TV registers no signal when the HDMI input is selected, and the Mac doesn't register a second display under the Display PrefPane. I'm assuming there's something wrong with the cable, but I've also read that it may be an issue with driver compatability in OSX 10.6.7. Any ideas?

Cannot Connect Imac 24" via mini dvi to HDMi adapter cable to Sony Bravia 3

Hello Everyone,
I'm having the worst time in trying to connect the following:
1. Imac 24" 3.06 dual with dvi connection
2. Mini dvi to HDMI adapter (this mac with this connection was produced only for a short while!).
3. 10' (foor) HDMI wire
3. Sony Bravia 32" model KDL32L-5000 with 3 HDML connections
i.When I wire everything up, I keep getting"no signal" on my Sony Bravia TV.
ii. It doesn't matter whether I connect the HDMI wire to HDMI 1,2, or 3 on my Sony
iii. On my Imac Hard Drive>>Applications>>System Preferences>>Displays
all I get is a list of different resolutions. There is no mention or mirrors etc.
Nothing happens when I press "Gather Windows" or Detect Displays"
Can someone out there please help!!!!!
Can you also give any solution in very simple and small detailed steps!
Thanks,

Majortrout, there is a major disconnect going on here.
1. You are showing an Ebay link with a mini-DVI to HDMI adapter.
2. You report that you have an Early '09 24" iMac.
3. That iMac does not have a mini-DVI port. That iMac has a mini-DispayPort.
4. You need a mini-DisplayPort to HDMI adapter.
It is physically impossible to attach the adapter to which you link at Ebay to your iMac. So you need to take a step back and figure out what you really have; which iMac, which adapter, etc.

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.

MacBook to TV via mini-DVI to HDMI?

I bought these items to connect my macbook to my Sharp Aquos 52" LC52D85U 120Hz 1080p LCD HDTV:

I have it plugged into input 6, but it doesn't appear to be working. Do I need to adjust the settings? have some type of software? what am I missing here?
thanks!
update: my background screen from the computer is now on the TV, but not the movie that I am playing.

I just hooked my macbook up to my sony xbr6 tv via mini-dv to hdmi. I had to go into system preferences, then displays. A sony display window appeared, then I went to arrangements, and clicked on mirror displays, and it appeared....I'm still trying to figure out how to get the sound through my tv...I thought I might get sound thru the hdmi cable, but I think I might have to use an rca cable...

Connecting to a Samsung TX-R3079WH HDTV w/Mini-DVI to HDMI

Greetings, I have a Samsung TX-R3079WH 30" HDTV that has an HDMI input (which works just fine via cable box input), and I have a Rev C Powerbook G4 12" 1.33 GHz with an nVIDIA GeForce FX Go5200 64 MB AGP graphics card with the mini-DVI output (which works with the converter to a 17" CRT via VGA).
I recently purchased a 4 m Radio Shack DVI to HDMI cable to connect the PowerBook to the Samsung TV. I am connecting the DVI cable through the DVI to Mini-DVI converter from Apple to the PowerBook.
At first, when I had the Mini-DVI/DVI connector attached to the laptop, I had the TV turned off and plugged in the HDMI cable to the TV. I turned on the TV, and my computer's display definitely recognized the external display. The problem initially was probably a refresh rate/resolution problem I guess, since the TV was reporting "No Signal" but the laptop definitely recognized an external display, which had its own icon in the System Preferences Displays panel (running at what looked like 640 x 480, definitely smaller than the native res 1024 x 768 of my primary display).
Anyhow, I didn't recognize what the problem was then, but now when I try and connect the DVI/Mini-DVI to the HDMI, all I get is incessant flashing from my primary display as it tries to decide whether or not there's something attached.
Any suggestions on getting this setup to work? Thanks in advance.

never mind found the mirror display function.

I have a 32in 1080p Sony Bravia. and a early 2009 iMac 20in. i bought a mini Dvi to HDMI adaptor. And i have the HDMI cable. but every time i connect my iMac with my Tv my iMac screen turns blue then back to the desktop.

i also click on detect displays and nothing happens.

You have the display set in Extended Desktop mode. In System Preferences>Display there should be an Arrangement tab when you have the TV hooked up to the MacBook and both screens working. 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 make the second monitor your main screen. When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.

Will Airplay via Mountain Lion work on 2 GHz Intel Core 2 Duo (mid 2007) iMac

One of the main reasons I would purchase OS X Moutain Lion is for its AirPlay feature, in particular to stream Hulu from my iMac to my Apple TV 2. In reading some of the preliminary reviews of Moutain Lion, AirPlay is not supported on older MacBook Pro's. Will it work on my mid 2007 iMac (model identifier: iMac7,1) running a 2 GHz Intel Core 2 Duo with 4 GB 667 MHz DDR2 SDRAM?
I'm currently running Mac OS X Lion 10.7.4 (11E53).
Any help is appreciated. Thanks!

AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer).

I recently updated my Mid 2007 iMac with the latest OS 10.8.5 now my external hard drives will not show up. They show up when I boot them up on a machine running and earlier OS. Is there a fix for this?

I recently updated my 20-inch, Mid 2007 iMac with the latest OS 10.8.5 now my external hard drives will not show up. They show up when I boot them up on a machine running and earlier OS. Is there a fix for this?

Can you see them in Disk Utility?
If so, can you select and Mount them?
If not, disconnect them, reset the iMac's SMC and then reconnect them.
Intel-based Macs: Resetting the System Management Controller (SMC)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
If you still can not see them, connect them back up to the iMac running the older OS, open Disk Utility and look to see how they are partitioned and formatted.

Mid 2007 iMac SSD in optical bay - cannot write to last block of device

Hi All,
I've just replaced my optical drive in my 20" mid 2007 iMac (Dual core, 2.4 Ghz, 2 Gb RAM running Mavericks) with a solid state drive (Crucial MX100). The plan is to transfer my boot disk to this drive while keeping my 1 Tb HDD for media and such.
I followed the ifixit guide and it all went smoothly, however when I try to partition or erase the new SSD using Disk Utility, it tells me "Operation failed - cannot write to last block of the device". After googling, I found some answers here that suggested the optical bay cable may be faulty, so I bought a replacement and swapped it in, but no such luck, same problem. I also saw some threads suggesting that the boot disk should be in the original hard drive spot, but since this isn't the boot disk (yet) this shouldn't be the issue.
My computer recognizes the new SSD but won't allow me to partition it. Any suggestions on how to proceed?
Thanks!

3. The new disk is just bad.
OK. If that's the case, I'll just get another disk.
Lots of problems with that hybrid drives on Mac's on these forums, get another one that's 7,200 RPM and from Western Digital, not Seagate.
With a 7,200 RPM you get more performance across the entire drive, not just what's cached in the small flash portion of the hybrid.
https://discussions.apple.com/community/notebooks/macbook_pro?view=documents#/
1. Hybrid drives: I'm on number 8 in 6 different machines, no problems at all, what happens when you try?
2. The OP is not using a Hybrid.
3. Lot's of problems with WD drives not booting on these forums though.

Recently I bought a mini DVI to HDMI converter from eBay for my iMac 21.5 Mid 2011, but only later I realised that it does not have the mini DVI port in that. How can I connect my iMac to a LG smart TV through a HDMI cable?

This is the picture of all the ports from my iMac
This is the mini DVI to HDMI converter which I bought from ebay. And I have the HDMI cable to connect it to my TV
Could anyone please suggest me a solution how I could connect my iMac to the LG smart TV? Also I need to know if this transmits the audio as well to the smart TV?
Suggestions are welcomed. I really appreciate and thank you for your time

I would suggest looking into a Thunderbolt to HDMI connector. In this case, you may be able to use the TV as an external monitor. For this option, please confirm through additional research. I have not tested it personally.
You can also use an Apple TV, which connects with HDMI. In this case, you can use Airplay Mirroring. Not all Macs support Airplay Mirroring, so you need to check first. I have a Mid-2011 27" iMac, and it supports Airplay Mirroring. I don't use it often because my TV is in another room, but I just tried it and it worked. It had to change the screen resolution to work well, so I don't know if I would want to use it as my day to day monitor. http://support.apple.com/kb/ht5404

How do I get my projector to recognize a mini DVI to s-video connection? (2007 iMac)

I purchased an adapter to display my (mid-2007) iMac screen through a projector. With the adapter attached to the mini DVI port, and an S-video cable attached to the projector, I get nothing (the projector says "no source found"). I tried "system preferences--->displays--->detect displays" and nothing happened (the only other option in that window is "gather windows" which also does nothing). I guess it's possible I could have gotten a defective adapter. I know the s-video cable is good since it works from my DVD player to projector. I'm trying to play a movie file on the iMac and project in onto a screen through a projector. Any thoughts? Thanks.

hey, thanks for those links! But, do you really it's a defective adapter?
You are welcome..! It most likely is incompatible.
I'd be bummed out if the OEM one didn't work either.
That is the problem with needing or having to buy outdated hardware that no one makes or supports.
What if it's the DVI port that's the problem?
The only way to find out is to test it with one of the following Mini DVI Adapters.
The Mini DVI to DVI adapter, a DVI cable and a DVI monitor.
The Mini DVI to VGA adapter, a VGA cable and a VGA monitor or VGA projector.
The Mini DVI to Video adapter, an S-Video or composite cable and an old TV or projector.
Several posts suggest selecting "mirroring" in the displays section, but that option doesn't show up)
The Extended Desktop and Mirroring options only work if a second monitor or projector is detected by the display preferences.
