I have the Apple 30" Cinema Display plugged into my 15" Macbook Pro with just the regular Mini DisplayPort-DVI adapter that is $19 at Apple. I am able to use both screens and drive the full resolution. Is there another reason to use the Dual link? I am consfused as to why you would need this?

I have a Samsung 36 inch TV(series 6 610/640). It's an LCD flatscreen. 1080i hi def, the works. I was planning on using it as my monitor, so naturally I asked the "genious" at the apple store about how to run the computer image to the TV. He said to use the mini display to DVI converter, than run a DVI to HDMI adapter cord to the TV. Blam.... OK I figured it was ok because I have an apple hi-def 30" display at my other place of work that I plug the same computer into, and in that case, I use a mini display to DVI adapter, then simply plug the DVI cord of my apple display into that. It works beautifully. But... but.. I get home, and get ready to plug this thing into the TV with the DVI to HDMI cord into a HDMI input in the back of the TV. So, the propriatary "Samsung" window comes up giving me the different resolutions I can choose from, and I found one that fit, but the image on the screen was grainy, and crappy.. I tried every possible permutation, between the TV's settings and the different resolutions offered on the Mac for the monitor. It did not work, crappy image, and the reaction time on the mouse was sluggish. It is like the adapter combination caused a problem with how the pixels are translated. Soo.... what I did was this.. I drove back to the Apple store (NY 5th Ave store open 24/7) and asked for a mini display to VGA adapter.. Yes the TV has a VGA input in the back.. And to the "genious" shagrin, he gave me the adapter while saying that the picture I would get would be worse using a VGA input than using a HDMI.. (mind you, before I made this second trip to the apple store, I searched many blogs where people were having the exact same problem as me, and saw this as a suggestion, after having considered it myself, but i figured, heh, I should get HDMI, the cream of the crop!!) Well... let me tell you.. I finally got home, I plugged in the mini display to VGA adapter, and I plugged in an old VGA cord I had laying around into the adapter at one end, and into the TV at the other. I simply had to keep the laptop open simultaneously as I had it plugged in to the TV. I opened the system prefrences "displays" window. Then I set the mode of the display to "mirror" my laptop screen. I then set it to 1920 x 1080 resolution. I closed the laptop to put it into clamshell mode. The computer goes to sleep, & I get a no signal message on the TV screen. Then I simply push a button on my external keyboard or mouse, and the computer wakes up with... voila!! a superb image of my desktop on the TV.. I tested it out.. Really it is a true to form Hi Def image. This is using VGA now folks. It is a PC designed port. I am sure that a HDMI is a step up from VGA for sure,.. theoretically.. if it actually worked with snow leopard in combo with the adapters, but it does not, and the VGA really offers a extremely rich and detailed image. I am very happy. So dont go for platinum, just shoot for the gold and youll be happy. Get the mini display to VGA adapter if you want to run your snow leopard macbook pro to a TV that has a VGA.

I had flickering issues after sleep until switching to the USB hub method mentioned in the original post. As long as the converter (firmware 1.02) is powered by the USB hub and not the Mac itself, it works perfectly with my 30" HP LP3065. Thanks for the tip! I've tried it with both a MBP 13" and Mac mini (both early 2009). No problems so far. My converter just arrived this morning.

When I have my brand new macbook pro 15" plugged in with the mini displayport to dvi OR hdmi OR MDP->dvi->hdmi - I get intermittent problems as follows. After the computer goes to sleep and wakes up there are a variety of problems. Sometimes it recovers, sometimes it freezes and wont wake even after disconnecting the external monitor. Sometimes it cycles through black, blue and dithered looking screen in what looks like an attempt to match the display but it will do this endlessly. I may have finally gotten some success by using a mini displayport to vga. But what is the point of having all this fancy and expensive hardware if we are back in analog VGA/RGB land? Another possibly related problem - when I have an external monitor plugged in AND the audio jack plugged into my stereo - I get terrible noise on the audio line which ruins any movie watching experience. So basically this brand new MBP is useless for watching movies on my home entertainment system. Which is a real drag. Ive been reading about problems similar to the 1st one but have yet to hear of the second one. Ive been trying every combination of adaptor and plug and power setting i can think of to troubleshoot this problem. I even have a 2 year old MBP with the older full dvi slot and it has none of these symptoms using the same external hardware and adaptors (excepting the mini displayport adaptor which obviously would not work with my older MBP) Apple needs to step up to the plate and find a solution because external monitors are a must for many mac users. I have a full Apple Care plan along with my laptop all purchased only a month ago so im hoping that working with my local apple store will resolve these issues. I'm having a possibly related problem.
