Mini-DVI to HDMI has poor quality on the TV

I am trying to watch TV On-line on my Samsung HD TV. I have purchased a mini-DVI to HDMI converter to connect my iMac to my TV. It's working, but the display quality is very poor. I have tried to Mirror the display and not and that's the same. The Display Settings for screen resolution and color only seem to make a difference on the iMac side. Is there something I'm missing. Any suggestions would be helpful. My TV has just about every kind of input available, so if mini-DVI to HDMI isn't the ideal I could have alternatives.
Thanks for your help.

The best option is an appointment at an Apple store genius bar. The evaluation will be for FREE!
Ciao.

MacBook 2007 black 13" would a mini-DVI to HDMI cable send audio to the TV?

I attached my macbook (2007 black 13") to my TV with a mini-DVI to VGA; would a mini-DVI to HDMI cable allow my audio to play through the TV? Wanted to ask before I purchased it. Thanks.

No. The black MacBooks don't send audio through HDMI, so you'd need to connect the audio separately.

VGA vs Mini-DVI to HDMI adapter

I'm about to buy an external monitor to use with my MacBook Pro late 2008. I do understand HDMI (digital) looks much better than VGA (analog), so I'm thinking about buying a Mini-DVI to HDMI adapter. My questions are:
Does the Mini-DVI to HDMI adapter decrease video quality? Is it noticeable?
Is it worth buying the adapter? If so, are there any known issues with third-party adapters?
Thanks in advance for your time!

If your macbook has mini-DVI then HDMI or no HDMI you will not get any audio passed through the HDMI connection because DVI does not pass audio. You would need to pass the audio separately via analog stereo line out.
But what difference does it make anyhow? You intend to use this as a monitor as opposed to hooking it up to a HDTV.
So long as you use a digitial interface HDMI, DVI, mini-displayport, etc. you are not going to loose any quality. It's digital. It either works or it doesn't. VGA, being analog, will of course be less quality.
I don't even know why you care about converting to HDMI when you could just convert mini-DVI to standard DVI and use a monitor that accepts standard DVI. They're plenty of those around.
Another consideration with a DVI interface is that if the monitor has a resolution greater than 1920 x 1200 you need a dual link DVI adapter as opposed to a single link DVI adapter.

"Mini DVI to HDMI" or "Mini DVI to VGA" to go to Samsung LN32B460 HDTV?

I recently purchased a "DOA"/defective "Mini DVI to HDMI" converter off of ebay, and the company is making me spend the $10 to return it to China - which I'm not doing (I only paid $10 for it in the first place).
I am wondering if I should buy another one, from a more reliable seller of course, or if I should buy the "Mini DVI to VGA" instead?
I don't play games, so it would be mainly for playing movies and browsing the web. My display is a 32" Samsung 720p (Model LN32B460). It is has a native resolution of 1360x768, 60Hz refresh.
Will I see a quality difference for the basic stuff that I am doing that I should get the "Mini DVI to HDMI" or will the "Mini DVI to VGA" be enough?
Thanks!

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.

After-market Mini DVI to HDMI adaptor

Has anyone tried an after market MINI-DVI to HDMI adaptors to run a video signal from the iMac to a TV?
http://www.monoprice.com/products/product.asp?cid=104&cp_id=10419&cs_id=1041912&pid=4852&seq=1&format=6#faq
I know Apple wants us to purchase their products...and in this case we'd have to purchase 2 adaptors/Cables (mini DVI to DVI & DVI to HDMI).....seems like a waste as each cable runs around $20 each when I could just easily buy one adaptor for $10 on monoprice.
For what it's worth, monoprice.com is very reliable, has great prices, fast shipping and very nice products. I use them for all my cable, wire, adaptor needs (and no, i do not work for them either). I used to be very particular about my cables and would fork up tons of money buying monster cables be it of the xbox, home theatre, cable box, HDTV etc all to realise that a cable is a cable, they all pretty much spit out that same quality image or sound regardless. So check 'em out!

Short ago I bought this adaptor to connect an iMac with my beamer (Mitsubishi HC 1100) and the outcome is - better than ever. Clearly you can say that one adapter is better than two. I can't believe that it took so long until this adaptor was developed. I had been looking for it already one year ago

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,
Stacey Bindman

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.

Mini-DVI to HDMI adapter or Mini-DVI to DVI cable?

I know Apple has a couple different Mini-DVI adapters for their Powerbook and MacBook computers. I don't especially like adapters and was wondering if anyone knows of a Mini-DVI to DVI cable.
Also, with the gaining popularity of HDMI, do you think we will ever see a Mini-DVI to HDMI adapter or cable?

Hi,
I know it is changing the subject, but I've been long frustrated by Apple's penchant for odd connectors, especially video connectors. Remember old quadras with 13 pin D connectors, powerbooks with square connectors, 7100s with I-don't-know-what connectors? All the while, ye olde VGA 15-pin D-sub connector was on just about everything else - even gas chromatographs.
We also got that funny mini-dix (Digital-Intel-Xerox) Ethernet connector on powerbooks when PCs were outfitted with familiar RJ-45 jacks. I did see one other machine that had the mini-dix: a government spec Zenith notebook.
I'm surprised Apple didn't use a VGA connector on the Macbook, given its above average exposure in the educational environment and greater than average odds of being hooked up to a lectern in a distance learning room. Pretty much to a tee, every distance learning setup I've seen has a VGA cable at the presenter's lectern. I worked in a university IT department, and it was pretty common for our loaner laptops to come back missing just about any ancillary goodie that could be misplaced. It isn't so bad to have to routinely stuff a new $2.00 cat-5 cable in the bag, but a $20.00 video dongle - not so good!
If Apple just couldn't countenance the idea of a VGA connector, I wonder how hard it would have been to have a normal size DVI connector? At least DVI-to-VGA connectors are easier to find, and better, aren't so expensive.

My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. It was working fine now I cant get it to output to the Tv. Any ideas?

My Macbook pro no longer outputs to my vizio led tv. It was working fine now I cant get any picture. It just says no signal. It is not the hdmi or the adapter because it works fine with my other tv. Any ideas on how to resolve this would be greatly appreciated. Please be as specific as possible. Thanks. BTW--I am using the mini dvi to hdmi adapter in case that was unclear.

Since you say that the same connectors work on your other TV is suggests that the fault is not in the connectors but your Vizio TV. I would check the settings on the Vizio TV. Verify that is is set to receive HDMI input. Perhaps you or some one else has inadvertently changed them. Pressing the wrong buttons on a remote control device can do that. (I am assuming no changes were made in SYSTEM PREFERENCES>DISPLAYS)
Ciao.

I have a late 2008 white macbook. I have a mini dvi to hdmi adapter, and a hdmi cord. My cannot get my MB to detect an external monitor. Nothing happens when plugged in. Also, my display settings does not have an option for mirroring or arrangment tab

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 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.

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.

Mini dvi to hdmi

I just purchased an adapter to connect my imac (intel core duo) to my lcd hdtv. I am using a mini dvi to hdmi adapter. When i plugged it into my imac and macbook it recognized my tv right away as another display. Is this the best way to get video to my tv? Is there another way to achieve better video quality?

That is the best way.
Is there another way to achieve better video quality?
Are you asking because the quality is not acceptable? It should be digital all the way, you can't get any better. If the HDTV is capable of 1080p, make sure the resolution setting in System Preferences Displays pane is set to 1920x1080. Also, make sure you are NOT using the Mirror setting; you want the two screen in extended desktop mode, using the optimum resolution for each screen.

Mini dvi to hdmi cable??where

i want to view the itunes visualizer on my 52" hd lcd sony bravia3. i would like to stay in the digital domain, thus use the hdmi connection. I searched everywhere. where can i get a mini dvi to hdmi cable. i saw mini dvi to dvi, is this the same connection minus the wire inside for audio?
imac G5 1.8mhz, and macbook intel core 2duo Mac OS X (10.4.9) wireless keyboard and mouse

what you want to do is get the apple mini div to dvi convertor and a dvi to hdmi cable from a good electical shop.
doing it this way for the video the screen shows the macbook as a box in the screen area, as in there will be a black box around the screen. this does this on my girlfriends lcd tv just a 27inch lg. though the tv only has auto detect for screen res. in my plasma, pioneer 46inch i get full screen but the top menu bar is only half showing, i havenot played with the settings on that yet.
for true digital or surround sound you are better to use an optical cable via the headphone jack. no point if u dont have a digital sound amp though

Mini DVI to HDMI cables- Will I get audio on TV

If I hook up a mini DVI to HDMI adapter to an HDMI cable and run it from my MacBook to my plasma TV, can I get video & audio without using the optical digital audio port?

stedman1 wrote:
Hi ypw: Good question indeed. I checked my Plasma (LG) there doesn't appear to be a separate audio input associated with the HDMI inputs. I seem to recall some posts on here pointing to the separate audio solution, but had never tried to verify.
I might try with my Samsung plasma TV at home.
I thought that the general idea of using the DVI to HDMI converter was just to use it like one would use a typical monitor without audio. Since HDMI already has digital audio and typically comes from sources (tuners, converter boxes, video players) with audio, I don't think there would generally be an option to use analog audio, although it shouldn't be hard to include that option.
I've seen a few things like converters that take component video and analog audio as inputs, with a single HDMI output. I don't know if anyone anticipated blending a different audio source when the source is already HDMI.
