Dirty screen effect (DSE) and mura are terms for panel unevenness, creating faint clouds, streaks, or patches on your monitor. This guide explains why it happens on solid colors, what causes it in LCD and OLED panels, and how to test for it without overreacting.
IPS motion clarity is often better than spec sheets suggest. Real-world performance depends on refresh rate, overdrive tuning, and frame persistence, not just a GtG number.
Visible PWM flicker at high frequencies is a real issue. The Hz rating isn't the whole story; pulse depth, duty cycle, and panel type create noticeable shimmer.
Panel pixel fill factor is the percentage of a pixel that emits light, directly impacting perceived sharpness. A higher fill factor creates a smoother, denser image.
Aggressive pixel transitions on some IPS panels create a sharper look but can cause overshoot and inverse ghosting. This happens due to stronger overdrive, faster voltage changes, and tight refresh timing. Get details on how panel generation and settings affect motion clarity.
Lowering your refresh rate gives pixels more time to transition, which can reduce motion blur. However, this change can cause inverse ghosting if your overdrive is set too high. The key is balancing refresh rate, FPS, and overdrive for the cleanest motion.
