When I'm working from home, I have the curtains in the room closed because my OLED is a curved monitor and any light from the windows reflecting on it creates glare on the sides due to the curve. For light I have two bulbs in the ceiling, each is rated for 900nits. I have my monitor set to 100nits brightness and also I have the windows blue light filter turned on and set to 30%. Anything over 120nits or less than 30% blue light filter is too bright for me
