Low quality Logo in Mobile View (blurry)

I have a PRO extension to megamax menu, and I use logo as a replacement, as it is reccomended in documentation. But the problem with logo is that I have it in high quality, and on desktop verison it looks very good, but when I use this logo in mobile view in megamax menu, then it seems little bit blurry, and loose quality. I tried to change resolution of image, change its height/width, but nothing helped unfortunately.
Maybe You have some advice what to do ?

Here is desktop version: https://ibb.co/WxhjdBp
Here is mobile version: https://ibb.co/BrJ1nR0

You can see the differences.

Hope you will help, best regards !
