About 40% of my older programs do not scale. Not a big problem since I am familiar with them.
Should also have mentioned that I wear glasses and my eyes are app 12" away from the screen in order to focus. So for my setup a monitor larger than 24" would not do.
I waited to get a 4K monitor until HDMI 2.0 became available by View Sonic so that it is compatible with our UHD 70" TV set. The monitor is very reasonably priced.
GPU card is a GTX960, only one having HDMI 2.0 connections and HEVC 4K encoders and decoders for video editing.
Paul, I too found 250% to be optimum.
