I have recently bought Lenovo Flex 4, which has windows 10 pre-installed on it. But unfortunately some programs have a very small interface and the text is barely readable (like in KMPlayer in the picture below). I've tried the "change size of text,apps and other items" tool from display settings but nothing changed. Is there a solution for this ?

It's worth noting that the problem isn't limited to KMPlayer,it exists in some other programs like Windows Media Player.
