I like the download version because he keeps updating it and you get new patterns constantly. You just have to have a way and source of playing the files on the USB drive you use. I have used the 4K FireTV box, NVidia Shield and Panasonic UB900 successfully with a USB thumb drive with these files loaded on it.Do you think it matters which version you get? the download version vs the Ultra Bluray Is the downloaded version going to give you 4k video? Or is this just patterns with no video reference?
Yes, the files are full 4K with HDR and BT2020 WCG.
