Compatible For IMac， A1418 21.5'' 4K LM215UH1 Control Drive Board SDA1/SDB1/SPA2 4096 * 2304 Mid 2017 MNE02 MNDY2 2015 MK45 LCD Screen Display

Core chip: Select the compatibility main control chip to ensure accurate signal resolution, adapt to different resolutions and refresh rates, and avoid picture lag. Interface design: It should cover mainstream interfaces such as HDMI, DP, USB, etc., and the interface protocol should match the latest standards to ensure stable data transmission and reduce signal loss. Power supply module: Designed with voltage regulator circuit, it provides stable voltage output to prevent voltage fluctuations from causing control board failures or display black or flashing screens. Keystroke. Touch response: The touch model needs to optimize the recognition algorithm to ensure instant feedback on brightness, color temperature and other adjustment operations without delay. Heat dissipation performance: The layout of the control board reserves heat dissipation space, and key components are equipped with heat sinks to avoid performance degradation or component burnout caused by long-term high-temperature operation.
