I knew it was too good to be true. After having exchanged my last screen due to the contrast buzz issue and an uneven backlight I find that my replacement v2.0 screen also has the dreaded contrast buzz below a contrast setting of 97 Interestingly this is a very different buzz to that on my previous screen which came from the top of the screen and was quite high pitched. The new buzz is much lower in tone and is coming from approx the middle of the right hand side. I will see whether I can live with the noise over the next couple of days as at least this screen has no dead pixels and the backlight is perfect. As someone has already mentioned on the forum its clearly not right that customers paying these sort of prices have to play russian roulette with QC issues!
