Resolution/DPI Scaling in Linux

Is there a program or setting to be able to scale down? I am using an HDMI connection and it is cutting off a bit of all sides. I am also using a 40 inch TV that to the best of my knowledge does not have a setting for overscale. I had to resize in windows. Any help would be great, would love to get this to fit the screen correctly.

Never mind. I just enabled my Nvidia card instead of the x server default it had. It downloaded it, I restarted and won’t even startup now. Kwin crashes and KDE environment and everything else. This was a wrong choice of a distro for the laptop. Thanks.

Did you install the nvidia driver with the provided driver manager or manually?

I used the one that was listed and said recommended in software sources. I ended up installing ubuntu studio and did the same exact thing and it booted up fine afterward. Thanks.
