So I am going to get the Lenovo y50 with the 4k display, and I am wondering if I don't want my computer to waste battery or gpu clock cycles on displaying 4k, could I set it to a lower resolution with the same multiple so the pixels are bigger, the screen display does not change, and there is less stress on my gpu and battery? An example would be going from 3,840x2400 to 1920x1200 without my screen width or image changing and my fps increasing. Is this possible?
