I have the HP ZR2440w now for several weeks now in use and am very satisfied with the services which have fully met my expectations: 1. good IPS panel with factory calibration acceptable and neutral color rendering (my monitor had only a minimal blue shift) 2. excellent illumination (my 2440er has a nearly perfect illumination, only the 'IPS Glow' bothers me a bit, but that's due to the system and a problem of IPS technology) 3. Low power consumption 4. No restrictions while playing with (de) activatable Overdrive (compared to my old TN monitor I have no problems even with fast games) 5. works absolutely noiseless 6. very good ergonomics (height adjustable, rotatable, stable foot, fast operation) In short, I can recommend the monitor for amateur photographers, sophisticated gamblers and office use without restriction. For its price, it offers a very good appearance, a very robust mechanics and a generous warranty.
