Hi, I have a problem. I had this monitor for 2 months now and used it with my laptop and it worked fine. I bought it though to attach it to a pc. I did that yesterday via Displayport and it said that it entered powersave mode. I tried method with unplugging and plugging cables and also tried to clean and even rearrenge (different slots) RAM. PC does't have any OS for now as I cannot put it without monitor, it should just display BIOS. By the way with the laptop after all this it still works fine. Thanks in advance
