To determine the correct for your device:
Older TVs, universal compatibility, small files.
| Your TV Age | Best USB Format | Why | | :--- | :--- | :--- | | | exFAT | Supports 4K files, fast mounting, no 4GB limit. | | 2015–2019 | exFAT or NTFS | Test both. exFAT is safer; NTFS works on high-end models. | | Pre-2015 | FAT32 | The only guaranteed option. Compress or split large files. |
Selected chips (e.g., RTL2832U) support direct I/Q sampling.
