JT Panzer campaign Graphics counters/maps

[dice4wargame]

Hello, I heard about JT Panzer Campaign games and I'm interested in them. I tried the Minus '43 demo but I noticed that when I zoom in in 2D mod, the counters/icon become pixelated. 

here, map in post #1 looks  good, but in post #4 the icons are pixelated.

In minus'43 i tried to set up small tanks/infantry icons on counters and they look good at zoom out level but when I zoom in, they become pixelated. It looks like the graphic .png is too small and when you zoom in, it becomes larger and loses resolution. I use 4K monitor and screen is large bur I do not think it is the origin of the problem since the posts I referred to, are from different users.

However, this problem does not exist in JT Panzer Battle games, for example in the following link:

The reason is that Panzer Battles are newer than Panzer Campaings games?
is there a way to avoid/solve this?

Thank you in advance.
