I tried increasing to 350 percent image still small if I enlarge by using pinch to spread screen I cannot do anything on the screen for input it jumps everywhere. I have the mentioned video card don't know if this is my problem because if I look on their page I see all downloads detected or my card only for windows7 and 8.1 I have windows 10. Seems to have gotten worse since I enlarged and I returned to the recommended setting now all screens miniscule. I am not a tech person so talking about IGUi's or whatever will mean nothing hoping you can explain in laymens terms something I can try.
