Resolution and Decoding: While the native resolution remains physical (often 720p or 1080p supported), the V2.0 software includes better codecs for handling modern file formats via USB. This ensures that high-bitrate .mkv or .mp4 files play without frame drops or audio desync.
Update Bar Doesn't Appear: Ensure the file is named correctly (usually MERGE.bin or similar) and the USB is formatted to FAT32, not NTFS.
