Sorry to see that. Mine was in the centre. Sucks.
I've received mine and touch wood, it seems to be all good. I am working from home today so I only had time to connect it up, run the eizo monitor tests and set up g-sync but so far so good. Didn't notice any pixels on the colour tests but I am yet to give it a proper try. SQL studio and visual studio do look good on it though! It is also surprising how noticeable 144hz is even on the desktop vs. my ancient 60hz samsung LCD I had before.
Coding in SSMS etc looks pretty good on it. I connected my work laptop and gaming rig to it at the same time - used the "Picture in Picture" function to have Sky news, netflix or whatever playing in the corner while using the rest of the screen for work. Pretty cool on an ultrawide.
Found "Picture by Picture" didn't work to great for me at two different resolutions but I still need to tinker with that.
