Help with UI size

Hello, I hope I’m not posting in the wrong place, please forgive me if so. I’m new to Parrot, and I have installed it on an external drive to use. I like it so far, but I’m having two issues. My first issue is that the UI is entirely way too small. It’s tiny, and I see no option to resize it. I’m running a 4k monitor. I resized the text and that helped slightly, but when I open terminal, it’s really tiny. I can hardly see my text when using it. Also, I’ve got an RTX 2080 video card, and for some reason, I’m getting no sound through it. I imagine that I should get the drivers, then see how that works. My main concern is the UI being too small, and all apps that I open being too small. Any help?

you can change resolution that will make your display bigger

Did you try increase dpi in mate-tweak?
