The high-resolution displays in sizes 7 "(17.78 cm), 10.1" (25.65 cm) and 17 "(46.18 cm) replay the pictures and videos in the 16:9 format, have a contrast rat This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 5310-00-033-3101, indicating validated use in U.S. government and defense logistics supply chains.
