ANX1120 Display Interface IC

The ANX1120 is a display interface IC from Analogix Semiconductor, developed for high-speed video signal transmission in laptop, desktop, and embedded motherboard designs. This IC is commonly used in DisplayPort (DP) and Embedded DisplayPort (eDP) circuits, enabling stable communication between the GPU and the display panel.

ANX1120 plays a key role in maintaining clear display output, correct resolution handling, and reliable signal integrity. It is usually located near the display connector or GPU output section on the motherboard. When faulty, typical symptoms include no display, flickering screen, distorted image, or resolution problems. Due to board-specific implementation, exact replacement is recommended during professional motherboard repair.
