1. The monitor was not handled properly and has been sitting on the wrong foot. Deviation to the side 1.5 cm height left side vs. right side. That bothered me massively and one mind neither LG nor the merchants my problem. You can not adjust itself as 4 screws pretend on the back of the monitor the position firmly.
2. For my usage with 4 split screen, so Outlook open browser open and 2 work programs are the windows just too small. At the end I had to change everything again on Screen 2 Split use.
Conclusion: I'll wait until the model as 40-42 inches is available and then get myself that for the office.
Until then, now I'm working with the cheaper little brother of this LG, the monitor is also available without height adjustment and without Curve and costs 500 EUR.
