A Mesc original - Making The Impossible Possible Get new release alerts and connect: https://mescoriginals.com/ Notes: I highly recommend a direct HDMI connection from the GPU to an 8K TV/Screen/Projector for the best playback experience. If you don't have access to an 8K screen, use Plex; it will downscale to your screen's max resolution on the fly. The default audio is 5.1 DTS-MA. The original 2.0 FLAC audio, a 2.0 Dolby Digital commentary track, and multiple subtitle options are also included. All stills were taken from an 8K HDR screen. Before (left) and after (right) stills are not full frame. Enjoy.
