One quiet Tuesday morning, the IT helpdesk received a ticket that quickly became the highlight of the week. The user reported that their computer screen was suddenly “unbearably bright,” making it impossible to work. Naturally, the technician thought this was a classic case of the brightness settings being accidentally cranked up or some glitch in the graphics driver.
The user’s description was clear and urgent: “My screen is so bright it’s hurting my eyes. I didn’t change any settings, and it got worse just a few minutes ago.” The tech asked a few routine questions—had the user checked the brightness slider, any recent software changes, or if the display cable might be loose? The user confirmed none of those applied.
After a brief-but-careful troubleshooting session conducted entirely over the phone, the tech decided to ask a simple but crucial question: “Is there any chance something could be reflecting sunlight onto your screen?” The user was silent for a moment, then admitted, “Oh… you mean like the sun? It is really shining right into my office window now.”
It turned out the user’s desk was directly in front of a large window, and the angle of the morning sun had shifted with the season. The sunlight was pouring in so intensely that it was making the screen appear blindingly bright, even though the actual display brightness was perfectly normal. The user had been staring at the screen squinting and assuming the problem was with their computer instead of the weather.
The tech carefully explained how natural light can cause screen glare and suggested repositioning the desk or using blinds to reduce the intensity. The user was both relieved and amused—they had been worried their laptop was possessed by some kind of brightness demon.
This ticket became a favorite reminder at the helpdesk that sometimes the solution isn’t sitting inside the computer at all; sometimes it’s sitting just outside the window.
