I started using ultrabook Asus Zenbook with QHD (3200x1800) screen. After week I realized that nowadays are still more problems than benefits with High-DPI screen on Windows. Some application ignores scaling to 225% and every time, when I connect external FullHD monitor, I need logout and login again to update scaling.
I decided to downgrade resolution from 3200x1800 to 1600x900 which is enought for me. Problem is that some text becomes blur. I thought that it's good idea to divide resolution by 2, because 1 logical pixel is now exactly 4 physical pixels on screen. What can be a problem that some text is blur?
