help my hud is super small

[twisted shape]

i was killing zombies like a pro and someone turned on a tv thats connected to the pc , both screens went black for a while and when they came back on my hud was really small and i dont know how to fix it
screen configuration on windows is set on show on display 1 (monitor) its a 4k monitor , resolution is correct in the game options

Maybe try restarting the game after changing it to windowed mode? The game probably tried to match the TV's screen resolution

4k Displays have a small HUD at the moment due to how the scaling works.
I recommend reading through this guide:
