Initially problematic

the first thing I'm really excited about this screen. However, I currently have a few problems, which is why I forgive only 3 star (should find a solution, I will still update).

Problem number 1:
I had the first screen connected via HDMI to my HD 6950 Radeon. When listening to music much to me then that the mute and volume up / down functions Roccat Kave 5.1 my and my Logitech G19 no longer work.
It does not matter which medium I hear sound if. On the screen boxes, via the headset or via the system The service 'access to input devices "was / is started, because it is so ever not.
A connection via DVI or DisplayPort has brought nothing.
So far, no solution is in sight.

Problem number 2:
Sometimes it happens that the screen is not detected when I connected it via DisplayPort. A switching to DisplayPort 1.2 On / Off then creates here remedy (but annoying just the switch each time you start the PC).
If I turn off the screen in PC mode and then switch on again, it may happen that me all open windows are set to 1/3 of the screen width. 1 time raised the resolution to 640x480 to ...

Problem Nummer3:
The Split software arises every time you restart the PC to restore. I want the automatic window splitting not use permanently, but only when needed.

Quick Note:
I rev01 and I do not rule out that fault on my side may be (am not a professional in the field)
Therefore, please only constructive comments;)
Keep working on solutions

--- Update 03/18/2014 ---
Forgot after my last update directly to change here the review again.
The problem no. 1 occurs, the LG own software Screen Split on if I have (no matter if connected via DVI, HDMI or DP).
This circumstance I emailed already LG itself and only got the question how do I get it and after my description only an info that the problem of the department has been forwarded ...
Until that is resolved, I find are in the price range 4 stars justice

--- Addendum ---
I forgot to post the answer of LG here.
".... After consultation with our development we could understand no problem.
It is always possible that drivers from different manufacturers interfere with each other.
Possibly more current drivers for the used accessories available to resolve the problems described. "

I find that more than poor, I think hardly that a test has been carried out, but that's pure speculation)
Because the price is now sunk again it stays at 4 stars. However, I would not buy this model because "my" Soft / Hardwarediskrepanzen again!
