The solution – (Again, for dual monitoring Mac mini users only) Use the mini-DVI output for your main display, and the mini display port for the secondary display. That way - disconnecting the second display (mini display port) will not affect the output on the main display (mini-DVI). This will not be an issue if you are using two monitors - and are not disconnecting your mini-DVI adapter.
Questions and Answers
1) Problems waking from sleep, and
2) That the adapter consumes one of the precious USB connections in addition to the mini display port.
Note that the Apple-branded adapter has many reviews with the same complaints, so I think this is more of a design issue rather than a quality issue. Although some say the newest Apple version with firmware 1.0.3 is better.
I think I have come up with a work around that addresses both of these issues. The USB connector on the adapter appears to be for supplying power only. It also explains why the adapter freaks out when the computer wakes up: it is trying to both establish the video connection while at the same time, power is just becoming available through the USB connection.
I simply connected the USB cable from the adapter to a spare Apple iPhone USB power supply. Now the adapter has continuous power and seems to wake from sleep without issue. Doing this also freed up the USB port on my MacBook Pro previously used by the adapter.
I just did this today, but so far, so good. I'll update this review if things change.
PROS: Connects a 30-inch cinema display to the new MacBook Pros at native resolution.
CONS: 1. Does not wake from sleep well
2. Consumes a USB port as well as the mini display port
3. Runs a bit hot
PROS: Works perfectly and gives 120hz option without DisplayLink Failure. Cables are long enough for any setup.
However, it does mostly work.
PROS: Allows a Minidisplayport or a Thunderbolt port to attach to a Dual Link DVI monitor.
Much less expensive than Apple's adapter, and I think smaller.
CONS: Seems to have issues with waking from sleep.
Seems to have issues with Single Link Displays.
Sadly, there are several situations where it doesn't work. I'm using it with a 27 inch iMac and a Dell 3007WFP. If I tell the iMac to "detect displays", or put it to sleep, or reboot, the adapter loses all communication between the computer and the Dell screen, and won't come back until I unplug the adapter from the iMac, wait a few seconds and plug it back in.
There's an almost identical setup here in the office using the Apple adapter with no such problems (although I've seen plenty of negative reviews about the Apple model too).
PROS: When it works, it works well, and it's cheaper than the Apple version
CONS: Connection to the monitor disappears frequently
I hate to think what the Apple's product is like, given the poor quality of this unit. Maybe, I have a dud? I have not had a chance to call Monoprice's tech support.
PROS: Cheaper than the Apple product
CONS: Lots of flicker and shadows
PROS: Easty to set up and is an active mini DisplayPort adapter
PROS: works as advertised
PROS: * allows for high-resolution display on 27" and 30" monitors.
* much cheaper than Apple's version.
CONS: * ties up a USB port for power (so does the Apple version).
I have two of these, and i have 2 DVI and 1 HDMI Sharp Aquos hooked into my Mac Pro now - zero configuration problems.
You might want to spend $5 on a POWERED USB hub to power them instead of using up your USB ports on your Mac.
PROS: Its $40 cheaper than Apple's adaptor which seems to not work very well per the reviews. And it works.
