I bought a Evnia 27M2N8500 and has been having issues too with the Pixel cleaning, sometimes i turn it on and it says its been 4 hours, or simply never show it the whole day... I'm not brave enough to brick the 700 euros monitor :( for the rest of the things i own i pretty much did the same as most of the OG software is just bloat, 1gb to just control pc fans is evil.
