Technical answers to common hardware, refresh rate, and browser diagnostic questions.
Backlight bleed is a hardware defect where physical light escapes from the edges or corners of the monitor bezel due to improper panel sealing. IPS glow is a natural optical characteristic of all IPS panels where corners appear slightly luminous when viewed from off-axis angles.
Yes, stuck sub-pixels (showing pure red, green, or blue) can often be unstuck using rapid RGB color cycling algorithms (like our Dead Pixel Fixer) or gentle physical pressure. True dead pixels (permanently black or unpowered transistors) cannot be repaired with software.
Frame skipping occurs when an overclocked or bandwidth-limited monitor drops incoming video frames instead of displaying them, creating micro-stutters despite high reported refresh rates.
