>>68431741nta but I say this a lot with her, you should probably adjust your monitor brightness. She's white, yes, but she's not so bright I can't watch her for 3hrs straight. I'm even the type of person to get headaches from looking at a bright monitor for too long.
I usually keep my monitors around 25-30% brightness in a dark room lit by a single lamp. Your phone would auto-adjust to the correct brightness in most cases, though it usually fails to adjust in very low light in my experience.
