My main use is normal office and web stuff, some image editing, nothing too demanding.
However and replacement must be less than 51cm wide (52 at an pinch but preferably not). I also want 1920x1080 resolution. Height adjustment would be nice, though not essential. DVI also a must.
My current thinking is a BenQ G2222HDL 21.5-inch, mainly based on my son's recommendation, he's delighted with it though would have preferred height adjustment.
