This is not a typo. Standard 4K UHD is 3840 x 2160 (often shortened to 2160p). The number 772160p implies a variable or slightly unusual resolution scaling, but in the context of the "Project 4K77" and "4K80" fan restoration community, it refers to the native scan resolution of the original 35mm film print.

These projects started by scanning actual 35mm release prints at 4K resolution. The "772" is often a hash or file identifier used by private trackers to denote the specific DNR or No-DNR version of the file.

The availability of "Star Wars: Episode IV - A New Hope" in 4K UHD (3840 x 2160 pixels) represents a significant leap forward in visual fidelity. This resolution offers four times the pixel density of 1080p Full HD, resulting in crisper details, more vibrant colors, and a more immersive viewing experience. When combined with HDR (High Dynamic Range) support, which was not explicitly mentioned but often accompanies 4K UHD releases, viewers can enjoy a wider range of colors and contrast levels, bringing the galaxy far, far away to life in a more realistic and engaging way.

When Disney released the "Originals" on 4K Blu-ray and Disney+, fans were horrified. Despite the resolution increase, the studio applied:

The "Star Wars 4K772160p UHD DNR 35 mm x265 V10" release serves a different purpose. It is archival. It showcases the heavy, delicious grain of Kodak stock. The "V10" denotes that the encoder went through nine previous failures to perfect the bitrate allocation: assigning more data to the thermal exhaust port explosion, and less to the static backdrop of Tatooine.
