Q: LG ultra wide monitor at end of TB chain flickers

I have problems getting my LG ultra wide monitor to work at the end of my Thunderbolt chain.

There is a Datatale thunderbolt raid enclosure with 4 drives and a Universal Audio Apollo audio interface with thunderbolt option card installed. From there I have a mini-displayport to displayport cable to my LG ultrawide screen.

The screen flickers from time to time, or turns off completely, accompanied by big spikes in the audio sometimes.

It's very frustrating and an unworkable situation for me at the moment.

Is anyone else experiencing these problems and/or has anyone found a solution?

MacBook Pro, OS X Mavericks (10.9.1)

    Yes I have the same issue. I'm daisychaining an Apollo Quad to my display using the Thunderbolt expansion and my Macbook Pro. LG UltraWide doesn't work in any configuration and I've tried another monitor which works fine.

     

    Did you find a solution?

     

    Maybe the LG needs more bandwidth than the Apollo can give when daisychained? I dunno I'm just guessing.

     

    I'm talking with UAD Support but I bet I have to get another monitor to use TB

    Hi there. Did either of you find a solution?

     

    I have just invested in a couple of Thunderbolt-cascaded apollos. My rig is wired as follows:

    Mac Mini- > Apollo1 -> Apollo 2 -> Samsung 27" DP Monitor

     

    With this set up I too suffer from flickering and cut outs. If I remove the cascaded apollo, all is fine. If I remove both Apollos, all is fine. UA support were incredibly fast in getting back to me, but said I should contact Apple & Samsung, as it SHOULD work. However, I doubt either of those two will give a hoot as they already have my money.

     

    Any workable solutions?

     

    Cheers
