Problem with TV Screen Bounds

Hello, I am not sure if this is the correct category, feel free to correct me if so. But I have an issue where my Laptop is connected to my TV, and my TVs has incorrect screen bounds (The TV was given to me without a remote and has no way of changing in Menu tab). Is there a way for me to zoom my entire desktop out to fit my TV? Currently I can’t have anything full screen due to being unable to see the corners/edges.
