For some reason, my U2711 runs by 59HZ, see ill. Below (in Danish, sorry). If I changes it to 60HZ, it just changes it back.

I use the dell-driver (date 24-07-2009) and a NVIDIA GeForce GTX 285. Windows7.

According to “the monitor” (Menu\display settings\display info), the resolution is 2560z1440@60HZ and the “main Source” is DVI-D1.

Thank you in advance
