I come from a professional Iiyama 19 "CRT monitor Have I struggled with finding a replacement CRTs are of the image quality simply super, but consume a lot of electricity, and radiation especially not a little:.. Spend hours in front of such a radiation source is unhealthy, makes headaches and burning eyes ... In the DELL I have come through various more reviews: The power consumption targets are given as 72W, but various tests show that it absorbs just over 30W, and is thus on a par with other modern monitors. The whistling in brightness change (the other recessions describe) has not delivered my Amazon device. The problems of inter-polarization I also can not see. Even in films, I find no problems. I have had both the U2312M and the U2412M since: In the 23 "picture was better, the 24" is more for office and games. Honestly, I consider myself already for critical, but there is a difference to be found for my use hard !! Both monitors are super. Since `s nothing to mekeln. The price difference is large, and if the 2cm for the small purse worth, has to decide each self. I am fully satisfied with the device.
