Video quality on Mosaic player is chrystal clear. In Kodi it's not: it looks like i'm watching a stream in lower qaulity.
I have this issue on two systems:
1) HD monitor, Geforce GTX 1070 card
2) 4K Oled TV, Geforce GTX 1050 card
Both using the same Mosaic server. 

I've been messing around with the video settings, but that doesn't change anything. 

How can i solve it? Or what should i do to examine a solution. Thanks for any help!

Sounds like streams are being transcoded.
This feature allows streaming to devices with low bandwith. Did you check transcoding settings?

/edit sry was assuming tvmosaic client was played locally. Is it?

 I don't use transcoding. It plays on machine 2). So local on 2), remote on 1)
