I have both the DGM (bedroom) and the DELL U2311H (in the lounge). It really depends on what you use your monitor for. The DELL is "ultrasharp" on text. It is the sharpest monitor I have ever seen. However, for colour reproduction (games/movies), the DELL u2311h, doesnt even come close to the images which the DGM can display. The other problem is the 1080p resolution...1200p is vastly more superior. If I was replacing the DGM with the DELL, for me, this would be a downgrade. No question. If you mainly do office work (word processing, spreadsheets, white backgrounds), then the DELL is a better monitor; in everything else, the DGM beats the DELL. PS: the DGM uses about 95W at the wall outlet, while the DELL uses 19W. I measured this using my electricity meter.
