my laptop has a bigger problem as it is running at Full HD on a 13" screen. The text is horribly small but I dont dare run it at higher than 125% DPI.

Not that this has any relevance to the problem, I altered the WiFi in our house today and changed the settings on my Son's laptop. I checked the resolution on his screen - it's full HD 1920x1050 and really nice. The text is small but very readable. So the difference between a 13" and 15" screen is going to be a big factor in readability.
