Dammit ....
urge to buy increasing ....
Yes, it powers on fine. Does the asus logo start up animation. Blank screen. Only a mini DP cable in the box so I had to manually select mini DP input in the options. Then the monitor goes into disco/epilepsy-inducing mode.

What type of cable were you using on your old monitor? HDMI? If so try it on the Asus to rule out a bad mini dp cable.
And ..... its been pulled ?

EDIT : any comments from OCUK or ASUS ?
Strange that OcUK allowed them to be sold when clearly Asus have arranged for all the units to be shipped back to them due to faults. I have found at least 6 websites that have stated this some more than 2 weeks ago.
Asus requested we pull them, they say the firmware has a fault that causes problems with 144Hz. They are removing all our stock and updating the firmware to fix the issue.
No idea on turn around time at the moment.
If it only comes with a mini DP cable is it best to get a standard cable when you buy it as my GFX card only has full size DP on the back of it
Looks like it comes with both according to the manual so you should be ok.

Mine came with only a fullsize-to-mini DP and a fullsize HDMI.
