Hi, Some TV's are handling differently media files playback from their USB and some times there is a mismatch with the playback that they accept from it's HDMI Inputs.
BTW Some TV's are disabling a lot of advanced calibration controls in USB Mode.
For the correct calibration way, you have to calibrate using as a source your actual movie content device (Media Player/Blu-Ray Player).
If you still want to use the USB of your TV as a pattern source, you have to test to see if it matches your player.
The best thing is to take some measurements (Grayscale/Saturation) from your Blu-Ray player and then use the same patterns to measure them from your USB..... Check the reports to see if the measurements from the both inputs are matching closely under meter repeatability tolerance.
Check also Contrast/Brightness/Sharpness/Clipping patterns using your Player HDMI vs. USB to see if they are matching also.
If you see that the levels/measurements are matching (count the meter repeatability also), then you will be able to use your TV's USB for displaying patterns from Media Files (MP4/MKV) instead of your actual player and later copy the settings you used at USB Input to the HDMI input your player is connected.
If you use only your USB port for movie playback then you don't need to run all these tests.
