I have come to seriously dislike Samsung. Seriously. I used to always get Samsung monitors for my PC and the last three I got all had issues with screen quality. I know it wasn't a fluke as I got two of one exact monitor and another one later and they all had intermittent issues.
I got a Samsung Galaxy S and returned it the next day I just really hated the phone and the screen protector didn't work.
My last two Samsung TVs were soooooooo slow to use their interface to stream from apps and the display a random stupid floating image on the screen when you mute rendering the mute button useless to me and I have to hold down volume buttons instead.
But I LOVE their direct competitor LG. I switched everything LG and phone and monitors are all great.
