Thank you all for your input. Unfortunately it hardly narrows down the range of monitors. One statement confirms my idea and that is the negative image of Acer but that leaves me a lot of other brands with whole series of types. I am convinced that several brands have types which are good value for money but I don't think I can make a founded decision without knowing why one brand can sell monitors of, say 120 Euro's and, at the same time, types up to 400 Euro's. The buyers must have a reason, I suppose....
