Kanex iAdapt Mini DisplayPort / Thunderbolt to HDMI Adapter with Audio Support for Apple MacBook, iMac, Mac mini, Microsoft Surface Pro3

There are some minor limitations that may be important to anyone who intends to use this with Hulu or ESPN3. I use it to connect my 2010 vintage 27" iMac in my home office to my 55" 1080P Panasonic Plasma in the living room (via a 30' HDMI cable). First, the picture and sound are terrific. But the picture is not "perfect". Here's what it's like using this device...I start by opening a browser and going to whatever show I want to watch. Then, I move the browser window to the upper left portion of the display. When I first plug the device into the port on the back of my iMac, the iMac's screen goes light blue for a few seconds, then the display reappears, reduced in resolution to fit the 1080 resolution of the Panasonic. Because the browser is already in the upper left portion of the screen, it is still nicely in view. Then I usually click on the Full Screen button on whatever browser I'm using.Note: if you want to preserve the size of your other application windows to fit when the device is later unplugged from the back of the iMac, at the screen's full resolution, then be sure to minimize those windows (using the window's upper left Yellow button) BEFORE you plug in the device. That way, when you retrieve them later they will be the full size you expect and desire. Otherwise, all windows showing on the iMac's display are reduced in size automatically to fit the reduced resolution that happens when the device is plugged in.When I go into the living room to switch the TV's input to the HDMI cable from the iMac, the TV's screen goes that same light blue, then shows ALMOST the same image as the iMac. "ALMOST" here means that the image on the iMac is slightly larger in coverage than the image that is displayed on the TV... the TV image is missing the very bottom of the iMac image, and perhaps a little of the sides too. Not much is missing, but enough to be important for controlling Hulu or ESPN3 (and possibly others). I use the "loop pointer in-air mouse" (which may not presently be available from Amazon) which uses a USB dongle (plugged into the back of my iMac) to control the pointer on the iMac from the living room. Other remote mouse pointers presumably will work as well.The point here is that the controls for pausing and changing position within a playback are often placed at the very bottom of the full-screen display. But the device has cut off (some of) that portion of the display, making it quite difficult to maneuver the pointer to make the desired changes from the living room with my remote mouse pointer device. (My remote mouse pointer lacks a way to remotely trigger the Esc key, which would take the display out of Full Screen mode, and thus make it easier to finely control playback.)There is one slight advantage to this with ESPN3. When replaying a previously recorded game, ESPN3 puts markers on the bottom of the display, showing where in the playback are the "important" plays. This is NOT desirable, since it takes away from the fun of being surprised. This is where I'm GLAD that the device cuts off the bottom ever so slightly, because those markers don't appear on my TV as I watch the game.I wish the device allowed control of what is cut off, but I'm still glad I got it. Hope this helps.

*Updated*This item works as stated! If you have a Macbook pro all you do is connect it to the computer's mini display port, connect a hdmi cable (separate cable that you must buy in order to use this) and then plug the hdmi cable into your tv's hdmi input port. The macbook should automatically start sending video and audio feed (Plug and Play!). If there is no audio, simply go to the system settings menu, select "sound" then choose your tv as the sound output device and that should fix the problem! If you cant see your computer screen on the tv, don't panic! because if you see your laptops background it works. In order to see your open windows and other applications, drag the application task pane to the right of your macbook screen until you go off the page, you should then see the window being dragged onto your tv. This is a really cool feature that lets you multitask with two screens. This is called a mirrored feature. If you would like to see your dock for full emulation, then in "displays", select "arrangement" on the top and select the checkbox for "mirror displays". If part of your screen is cut off, go to the "displays" in system settings and on the right there is a slider control called under scan. Manipulate it to your liking and it will adjust the screen size. In the same displays menu, you can choose your output resolution all the way up to 1080p but you can play around with the resolution to see which one suits your liking. You can also have a video playing on the tv that you dragged over there while you check your email on your actual macbook pro's screen. With this device you can also decrease your laptops brightness to fully black and the video output's visibility will be unaffected so you can save your computer's energy. Overall, this device is definitely worth it. Great Product and I hope this review helps!

The Kanex iAdapt works reasonably well with my MacBook Air (late 2010 version w/January firmware upgrade), but only in extended desktop mode. With my 37" AOC HDTV/monitor, when I set the screen display option to "mirror" mode, in order to see the same picture on both the MacBook and the external monitor, the MacBook freaks out, repeatedly trying to re-sync the video in a non-stop loop. Rebooting doesn't solve the problem, so you have to hover over the computer's trackpad and try to get the MacBook out of mirroring mode in the few seconds you have here and there between re-sync attempts. Very tricky! Interestingly, when I plug the MacBook it into my Pioneer A/V receiver using the iAdapt, this problem does not occur. I am able to use mirroring mode with no problem. So just be aware this may be an issue with some computer & monitor combinations. My AOC is a few years old, so might not be up to the latest HDMI specifications.Regarding the picture quality, there's a tiny bit of rainbowing on fine lines at 720p and the picture is a little too magnified when displayed on my 37" monitor. The 1080i setting produces a more natural picture size and the rainbowing is gone, but the picture's slightly jittery on this setting. Those were the best two settings for me, since my monitor does not support 1080p. (A few other resolutions are available via the MacBook's screen display preferences, too.)The HDMI audio works just fine, as long as the computer's audio is set for HDMI output. Also something to note: I found the iAdapt itself to be a little lightweight and plasticky. Not bad, but not as hefty as an Apple-branded adaptor, which is not yet available in this configuration.

Works Great

Horrible; la caja venía abierta y al abrirlo se veía que el cable estaba usado (tiene incluso un pequeño piquete en la carcasa). Para colmo, el cable NO funciona en absoluto. Probado en 3 televisiones (LG, Samsung y Toshiba) y con dos portátiles (HP con Windows 7 y MacBook Pro con Yosemite). Hay que tener en cuenta que tengo otro cable que si funciona con estas televisiones y portátiles. Asi que no se, se suponía que era un producto PREMIUM, pues vaya estafa...

Cumple perfectamente con su cometido y es económico.Funciona correctamente en mi MacBook Pro 13 pulgadas de mitad del 2012.En dicho portatil dispongo de Thunderbolt (en lugar de Mini DisplayPort) y es compatible y funciona bien, que es la principal duda que tenía al comprarlo.La única configuración que tienes que hacer es la primera vez que lo conectas seleccionar la salida del audio en System Preferences/Sound/(Y seleccionas la salida de TV que te saldrá tras conectar el adaptador).Recomendable!

Si quieres conectar un portátil Mac a la tele probablemente la mejor opción que hay, con una relación calidad/precio muy buena. Recomiendo al 100%, me va de vicio, cuando otros me dieron problemas.

El original de Apple es muy caro y da la misma calidad que este.El acabado de los materiales es muy bueno y lo bueno es que es ademas es compatible con Thunderbolt. Sin duda una muy buenas compra.
