An excellent monitor especially if you can find one under £100!
I bought this as an upgrade from a 24" LG monitor which was 1920x1080 max.
It is very sharp but my p^() Matrox card which would go to 2560x1440 would not do so with this monitor. As a result I had to buy another graphics card an NVIDIA GeForce GT710. This gave me the higher resolution but not Matrox's gorgeous colours so I am now looking for a Matrox card that will give me 2560x1440 with this card.
This is not the fault of the Dell but I'm just warning of the pits one can fall into.
The Dell is very solidly engineered and overall I am very pleased with it. If I can only find which Matrox card that isn't designed to drive 4 monitors and doesn't cost me £500 plus I will be in nerd heaven.
