Hello all,

I would like to share my experience with the MOSHI Mini DP to HDMI for all those who have problems with it, I have a Macbook pro 13" (early 2010) and some weeks ago I purchased one of those MOSHI adapters which as far as I know is the only one that can send audio and video to your external monitor or HD TV (very cool). Well, unfortunately it also stopped working after some days of use so I made my research on internet as many of you with no luck finding a good solution, I found nothing but a lot of people complaining about this same adapter.

I decided then to make my attempt to fix it with my own hands and when I looked closely to my adapter, I realized that some of the small PINS of the Mini DP connector side of the adapter were completely folded all the way through, this happened because the small plastic pieces that holds all the pins in each side of the connector got damaged so a couple of the pins were loose and consequetly got folded all the way through in one of my attempts to connect it back to my macbook.

Fortunately, I was still on time to apply the warranty so I got a new adapter from the store.

My advise for you is that you should be very careful while connecting it to your Macbook, the MIni DP side is very delicate, specially those small plastic pieces that holds the pins inside the connector. If you notice that your adapter has those pins folded then you are screwed and is time to get a new one.

I bought a mini displayport to HDMI cable at MicroCenter about 5 months ago. Unfortunately, I never got around to hooking it up between my MacBook Pro (mid-2009 model) and my Samsung 40" 650 HDTV. When I DID try it tonight, all I get is the wallpaper! Not menu bar across the top, none of the files on the desktop, no Firefox browser, etc. Just wallpaper! Any and all help would be greatly appeciated, and I REALLY hope I don't have to go through that VGA adapter crap! As someone else said, this was an advertised perk for this MacBook Pro model, and I'm seriously bummed that it doesn't work as advertised!

I just wanted to write that after the recent 10.7.2 software update, my non-functioning in OS X but working fine in Windows Mini DisplayPort to HDMI adapter now works great in OS X. All problems resolved. If anyone is having trouble and is running Lion, I'd give upgrading a shot.

I had this exact same problem. But I noticed that my mini display port to HDMI adaptor (the short white cable) was bent. So I gave the HDMI cable some more slack and straightened it out, and it works fine.

So if in doubt, straighten it out.

MacBook Pro mid 2010 & Moshi HDMI adapter worked fine for 12 months then stopped working. Checked cables and TV ports with other appliances, all good so back to the Mac. Tried connecting everything up first then turning on hte Mac, screen started to flash on and off like a frequency mismatch.

Upgrade to Lion, the TV screen briefly blanks then returns to defaul display. Checked using two adapters, two cable and two TVs with different resolutions, still no fix. Straightened cables, no fix. Any help would be welcome.

Is the mini display port to fragile to handle connection and disconnection on portable? What does that mean for Thunderbolt peripherals?

Having the same problem, and I'm running OS X 10.7.2.

Mini display to HDMI worked fine before the upgrade. Now when I plug the HDMI cable to the Mac, the screen blinks blue a couple of times, and then returns as if nothing happened.

Have tried it with 2 different mac's - problem persists. Have tested the HDMI cable, and it's working fine when I using bluray player.

Hi,

I am going to buy a mini display port to hdmi, need advice whether to go for an adaptor and use my hdmi cable i already have, or just go for the cable. I've seen lots on ebay, but thinking the cheaper i buy, the less chance of it working.

Any models/makes you recommend?

The cheap adapter that I bought on ebay worked fine for video but did not support audio. The Moshi was great, HD support, AC3 audio,worked really well until it stopped working. So now I have two adapters failing to work, checked against two different HDMI cables and two different HD TVs, Snow Leopard and Latest Lion. I will have to borrow a mini display or THunderbolt Mac to do a final check but I am suspecting that either the port or the OS is the source of the problem.

I'm not too sure if my macbook pro will support audio through any adapter because i brought it in mid 2009 and i've read that only macbook pro's made from mid 2010 will support audio, is this true? Also when you say it doesn't suport audio, does audio still come from the laptop or is it complety muted?

I may just go for the moshi and if that breaks, go for a cheap one off ebay.

I, too, have a Moshi Mini DisplayPort-to-HDMI adapter that works (er...worked...until last night) with a 13" MacBook Pro (running 10.6.2 Snow Leopard) from May 2010 with my 40" Westinghouse HDTV, connected to a standard HDMI-to-HDMI cord from Walmart.

Last night, we plugged in the Moshi Mini DisplayPort-to-HDMI adapter into a 2008 15" unibody MacBook Pro, running 10.7.2 Lion. We got the blue flash, which was good. Then, we plugged in a different HDMI-to-HDMI cord, the one that came with our Blu-Ray player, in turn into a 22" Samsung flat panel monitor.

No picture on the monitor.

I clicked 'Detect Displays'.

Still nothing.

This monitor has worked for the past 11 months with our DVI-to-HDMI cord, from both our 2003 15" PowerBook G4 and our Early'08 15" MacBook Pro (both running 10.5.8 Leopard) -- using an additional aux cable for audio, but on the newer, non-unibody computer, it worked perfectly in Display Mirroring and 1080i side-by-side arrangement.

I examined the Moshi adapter under fluorescent light -- it looks to me like there is no damage. I read this thread and straightened out the cords, changed the order in which I plugged them in, power-cycled everything, tried every single possible choice of resolution on the Display SysPref pane... nothing. I can't figure out how to change the refresh rate (following a piece of earlier advice) in OS X Lion because the Samsung display does not show up at all.

At first, I thought that the Mini DisplayPort in the unibody MBP was not working. But doesn't the blue flash mean that it is connected and functioning? What do I do next, go out and buy a new cord, new adapter or try the Moshi again with a *different* Snow-Leopard/Lion Apple computer?

Hy Guys,

I jsut bought a HDMI cable and a Mini DisplayPort to HDMI adaptater.

And like everyone when I plug it with Macbook pro 13" ... i got a couple of blue sceen and nothing....!!

Please Apple with need help!!!

Thanks

I think I may have stumbled upon a clue.

I just bought Air Display for $10 in an attempt simul-displaying on my iPad 2, and in turn connecting the iPad to my display with HDMI.

Well, Air Display, in its first screen, displayed this:

In short, if won't work if you upgrade to Lion and have an NVIDIA GeForce 9400M graphics card.

I do have a late 2008 MacBook Pro running Lion (10.7.2) with the NVIDIA GeForce 9400M. That machine did not work with the Moshi adapter connected to my Samsung 22" display.

My older (early 2008, activated May 22) MacBook Pro running Leopard (10.5.8) with the NVIDIA GeForce 8600M GT works with Air Display -- the Desktop perfectly mirrors or provides additional real-estate -- but the iPad mirroring that Mac's Desktop will not display on the big screen.

So am I right in assuming that the update works for users running Lion who have *DIFFERENT* graphics cards than the NVIDIA GeForce?

If you are still having issues connecting your MacBook to a display using a Mini DisplayPort-to-HDMI adapter, LIST YOUR GRAPHICS CARD.

Let's see if we can get this fixed.

This is what worked for me....I plugged incable to computer and my LG 42 inch 1080 HDTV. I aslo received the flickering screens....then I went to Apple icon> System Preferences>Display>Arrangements>Select Mirror displays. This worked great for me Hope this helps!!!!
