Mini display port to HDMI problem

I have a MacBook and for the second time trying to connect a belkin hdmi USB adapter to my TV it doesn't recognize it. I also have verizon fios cable box and once I connect the hdmi to computer the cable box ends up not working. Anyone else with this issue?

I pressumed this would not work, but in desperation, when no cable would work I went ahead and tried it any way and sure enough it did the trick!

Using iMac 7,2 lg26le5300 and snow leopard. Thanks for sharing your creative fix. Still blown away you must have 2 sets of wires to trick the iMac into communicating with an external display...

I am having similar problems, my cable is plugged into my computer and TV, it goes blue as though it is going to work and but then nothing happens. I go into my System preferences and go to Displays and it doesn't show that the cable is there? Even though the screen went blue like it was registering it?

Cable worked not that long ago? Is this a MAC software problem? Cos I can't find anything that works Someone PLEASE help me. or MAC please correct the software cos it worked perfectly before.

Cable is fine and a MAC one, so isn't the hardware.

PLEASE HELP ME!

Blue screen generally means No Signal, not Display Detected.

Holy bells, that actually worked (leaving the adapter plugged into the laptop, turning on the tv, and then plugging the HDMI cable from the tv to the apapter in the laptop). I didn't expect it to work, but it did.

Thank you Ponponhead!

Hi, I have plugged in my hdmi cord through the white cord and then in the mac, it has worked before on TV, then I used the cord of my brother's TV and now that I will be testing at home again it will not work. Do you know what setting i need to change or whats the problem? Thanks in advance!

Spoke too soon - worked once and that was it. The macbook sees it, but nothing is displayed on the Samsung. Very frustrating!

I should mention that it worked great until I purposefully disconnected to make sure the process worked.

I did see someone was unplugging their dell monitor and seemed to have good results, so I resorted to unplugging the adapter, power cycling the samsung display (using the switch at the plug - not just powering it off). Once the display powered up, I plugged the adapter back in and switched to the hdmi source - and it worked! I have now duplicated this twice... not sure I want to try any further, but this is progress???

Okay, so as I have mentioned before: I have been going through the same problem as everyone here. I tried out a number of methods, and a few of them worked (turning on the TV, and then plugging the HDMI cable from the TV into the HDMI > Thunderbold converter). This all worked for about a week, after my converter began gving trouble.

Now, however, it doesn't work AT ALL. Similar to many responses on this thread, when I turn on my TV, a blue screen blonks twice on my MacBook, but nothing happens.

I have been reading a number of other threads & complaints about this exact issue, and basically, it comes down to the fact that there is no specific way to get it to work. Basically, the Apple product (the converter) is a joke, and most of them die out anywhere between 3 to 6 months. If yours has worked for longer, you are one of the few lucky.

Time to go out and buy a cheaper, non-apple made converter.

I have 40 something inch Sony bravia TV with bunch of HDMI slots and a macbook pro with mini DVI adapter and hdmi cable plugged into TV from my laptop but sometimes it works sometimes it does not. It started recently and I am really bummed about all this.

What can I do to make this POS equipment work so I can enjoy my movies?

thanks!

The short (and unhelpful) answer is to buy something other than an apple laptop. There are 52 pages (4 years worth) and counting of those of us with issues relating to the simple act of connecting a laptop to a non-apple external display. I can't say I've read every page but I don't recall ever seeing an offical apple response that addresses this issue. Do 'they' not read or respond here?

Hi everyone, from time to time I check back here and find people having this problem. I had this issue a year ago and tried everything, and i mean everything. What worked for me was throwing the bloody adapters away and getting a hdmi to minidisplay port cable from Neet. I have had no **** issues since then. Connecting from mac to samsung monitors/TVs, optoma projectors, and dell monitors. To all of you, please try this.

Guys... Just go to an apple store and buy an apple Hdmi cable.. If you can give 1000 bucks to buy a mac, it wont be a problem to spend 30 more. I spent much more to other cables and combination, until i got one a year ago and everything works fine.

I can't agree with Vic-zx more! I was having the exact same problem--bought a mini display port adapter with an HDMI converter with a separate hdmi cable and it did not work. As soon as I took the converter out of the equation and bought a minidisplay port to hdmi CABLE it worked immediately after I plugged it in. All I had to do was change my sound settings and this cable does both video and audio. It has been working great since I got it. I purchased a simple off-brand product off of Amazon for about $7. Can't beat that.

dear vic, gio and hg

Please read part 4 of my post on page 41 (probably the last post on that page). I have reiterated the point in page 46 and page 50.

So the solution is there in the forum but you need to read through the stuff patiently.

Welcome to the long list of people who could get it to work by ditching the adaptor and embracing the cable.

why doesnt this POS equipment work? I have 2010 macbook pro, new cable from castco, and the moshi moshi adapter. it works sometimes but sometimes it does not, why? is this an eminal or a freaking computer? it should either work or not, whats this crazy behavior? ******* HATE this ****. I spend money on good **** and I expect it to work, if I have to come to this site and this all this JUNK it isnt worth it for me man. You guys figure it out and then post it right here in capitol letters why dors this **** works when it wants to.
