Hi guys,

Recently, i have been struggling with a thing...i have a desktop and 2 monitors. The second one was bought recently as its purpose is to be the extended one. So, my problem is that even both displays are connected to the motherboard's ports, there is not the extended option in Screen Resolution settings. I am wondering if this is happening as i use 1 graphic card. Both have no the same resolution but if i set them to HD resolution range then are mirroring as expected. Could this be the case?

Thanks in advance
