CalDigit Thunderbolt Station

[chrfr]

Your answer indicates that since the Caldigit is a DOCK it therefore is fundamentally not able to operate in this manner. Correct?

P.S. Not being testy, just wanting to dig down to the facts.

thanks,

Correct. The dock needs to be powered.

I now have the dock and can note:

1. The whine some people have is removed for me if I turn off the power (just an electronic switch) on the monitor that the DP-DVI adapter is connected to.

2. Using a 2012 MBA with HD 5000 graphics I now have triple head:

1. Internal panel
2. LG 34UM95 at 3440 x 1440 using Thunderbolt
3. BenQ panel at 1920 x 1200 using DP to DVI adapter off the Caldigit (connected after LG monitor)

a small miracle! Going to try and use the BenQ with HDMI to see if performance improves or gets worse. Might only be able to get 1920 x 1080 out of it. Will try some tricks later with EDID spoofing, etc..

My replacement unit is mostly working as it should for the past months.
Now one additional issue for me is with external USB HDD.

I have a WD USB3 external drive connected to the dock. Scheduled CCC to clone my OS drive to the external drive everyday.
Now when the MBP sleeps, it doesn't handle the drive properly. Often I wake up my MBP I get a message saying the drive was not ejected properly.

After few months my USB drive is now dead.

Noise @ 6.73[kHz] and 13.46[kHz]

My station sometimes also made noise (I sold it).

I captured the noise spectrum with a measurement microphone through a preamplifier connected to an oscilloscope (with FFT).

Conclusion: a whine @ 6.73[kHz] and the second harmonic @ 13.46[kHz].
It's a pretty irritating noise for young persons.

Help me here, as I'm finding my thunderbolt station less and less useful.

Late '13 rMBP. I just bought a Samsung U28D590D (4K), and it´s a delight to use with OS X. Now I have a 28" retina display.

I know TB station can't power 4K displays, it would need TB 2 / DP 1.2 for that. However, I'm trying to power a 2nd external display (an old 17" 1280x1024 LCD) via HDMI, and I find it impossible to power both displays at the same time when HDMI cable is connected to thunderbolt station HDMI port. However, it does work fine when connected to the rMBP HDMI port!

Is this normal?

I already have to connect 2 cables (displayport for 4K monitor) and thunderbolt for TB station, I really could use TB station HDMI port for the 2nd monitor...

You can't use the HDMI port on the thunderbolt station with another HDMI/displayport monitor off the other thunderbolt port of the caldigit -- you have to hook one directly to the laptop as you observed. This used to be on the caldigit FAQ somewhere...

You might be able to run 2 off the same thunderbolt port if one was a thunderbolt monitor.
