Disappointed with Samsung

I bought a brand new Samsung 24" computer monitor on the 23th January 2016, and exactly two years later, the screen is showing an ugly dark green colour. I have never known a PC monitor to have such a short life. I have now bought a second hand Dell Monitor which I am sure will last longer than the Samsung. The only reason I gave the rating 2 and not 1 is because their TVs seem to be quite good, but as far as their computer monitors are concerned, I would steer clear and look for any other make. I had a Proline monitor for about 4-5 years, and gave that away to a friend when I needed a bigger size, and that Proline is STILL working for another 4-5 years down the line. Monitors are supposed to last, and Samsung has failed miserably on this front. NOT a happy customer!
