Information on Energy Star’s website indicates that Dell is developing a 25″ monitor with 2560 x 1440 resolution. The U2515H appeared in a filing on the website and apparently uses a TN panel. However, TFT Central claims that the monitor is based on an IPS panel from LG Display called the LM250WQ, which entered mass-production last month.
LG’s panel has a 14ms grey-to-grey response time; 1,000:1 contrast ratio; 178 deg viewing angles; 350 cd/m
