Had the monitor return ....

I bought the monitor connected to the beginning of April and a HD7870 via DP.
After what felt like ten minutes I had edited the standard profile via the monitor menu and graphics card settings and especially after shut by Vivid pixels, had a really good picture (without frosting) at 40% brightness ..

The processing, the pedestal and the image are just for the price, very good and there is nothing to complain about ...
All AMVA + diseases, such as the lack of black level at certain angles, were known to me before purchase. But I also do not sit n meters next to the monitor, but in front of it.

There is also no PWM fibrillation, for a PWM bleeping which is so loud that I can hear it myself on two meters.
Although I read that he whimpers, but from ~ 30 cm distance no longer hear it.
As I sit away about 60-70 cm from the monitor, I thought it was not a problem ... None ...
Effective work is thus not possible for me, after a few minutes I'm the bleeping extremely on the cookie ...
Remedy managed only
a) 100% brightness (which to me then is too bright)
b) music at low volume or
c) tear open the office windows and the street noise listening ..
What are also no options for me and therefore a no go for this monitor.

For those who are not as sensitive to noise, this is a good monitor.
The price for a very good picture delivers ...
