Seeing this post about laptop repairs reminded me how often I’ve needed to check my screen for issues before deciding on repairs. I recently used an online screen test https://allcolorscreen.com/windows-update to diagnose some flickering on my laptop display. It was really helpful because I could pinpoint that the problem was with the screen itself and not the graphics card. This made my conversation with the repair center much smoother, and I felt more confident about getting the right fix without unnecessary costs.
