Question: Will this drive 2 monitors ?   E.g. One via TB-display port and one on HDMI ?   Mirrored or split?
Document: The dock seems to get a bit warm, but not super hot while in use. I am watching this, but I assume all of the docks get this way.2. I wish there was 3 thunderbolt ports and 3 USB ports on the back.3. I also wish the audio input port was on the back. It seems weird to have it on the front next to the headphone jack.Things to NOTE:1. This will not support dual monitors with the HDMI port in use.
This thunderbolt dock works really well with Mac OS Mavericks on my MacBook Air through the Thunderbolt port and it even provided the powered USB port. But here are the downsides to this Thunderbolt dock.1. There is only on Thunderbolt port, so unless your Thunderbolt device has multiple daisy chain ports, you cannot plug more than one Thunderbolt device.2. Works very erratically with Bootcamp on Windows 8.1, particularly the Thunderbolt display.
I am using the display port on my monitor to thunderbolt on the back of the dock.I will follow this review up in a few weeks with additional use, but this people is the one, so don't even waste your time looking at the other guys. Elgato hit it out of the park with this dock.
Elgato then sent a replacement, and the "... Slot 2" device now appeared but the device does not get an IP address (DHCP) from the router. I've even tried manual configuration to no avail. As mentioned above, the Apple Ethernet to Thunderbolt dongle with the same router etc works without problem, so I must be doing something right.The Elgato support (pretty responsive BTW) never gave me any feedback on what was wrong. E.g.
Thunderbolt displays and USB devices connected to the dock work fine.However, I never got the Ethernet working (and am not sure the other reviewers have tried) - so if you need this you may want to consider a different device. E.g. I am using the Apple Ethernet to Thunderbolt dongle without issues.Per Elgato tech support, a device called "... Slot 2" shows up in Network Preferences when the dock is connected to the mac.
Excellent option to provide a pass though thunderbolt port and HDMI for a mac mini.
I've been using this dock for about a week and it is doing exactly what I'd hoped. Despite previous reviews indicating otherwise, the ethernet port is working just fine for me. And with my MacBook Pro I'm able to get full 4k resolution at 3840x2160 right out of the box using the Elgato HDMI port. Likewise, the thunderbolt connection to my 1TB LaCie RAID is working flawlessly, as is the USB connection to my Samsung BluRay burner.
(2) It runs quite warm. Even my 1G 8-port Linksys router runs much cooler than the Elgato dock.
I had no clue that they recently released a thunderbolt dock, so initially I was skeptical and figured they would have the same drawbacks as the other manufactures. This was completed wrong. The dock is easily the best one on the market currently.Things I LOVE:1. The dock is extremely small and light and had a great sleek aluminum outer shell. It blends in with my desk and hides nicely.2. This thing is QUICK!
Most likely a software issue (the Ethernet PHY was detected e.g. by the router) - despite my questions I never received an answer if the difference was a firmware update. I've also mentioned that I was running VMWare fusion, thinking this might interfere with the network drivers. Elgato had nothing useful to say about this.In short, while their support is responsive, they do not appear to be too savvy dealing with this type of issue.
Answer: You can connect an HDMI monitor and an Apple Thunderbolt Display to Elgato Thunderbolt Dock, if you Mac is powerful enough to support two displays of that type.Please see this exhaustive article for more details about when you can (and can't) use multiple displays with Elgato Thunderbolt Dock.http://help.elgato.com/customer/portal/articles/1491132-how-many-displays-can-be-used-with-elgato-thunderbolt%E2%84%A2-dock-Note that using a DisplayPort monitor or adapter may limit your options.Whether the displays are mirrored or split will depend on the graphics system and settings of your computer, and not Elgato Thunderbolt Dock.  If your computer is powerful enough, then a split configuration will work as expected.
