Sony demonstrated a projector that can do 4.5K. This resolution has as many as 7680x4320 pixels. This is at least four times better than the current 1080P that has 1920x1080 resolutions only.

The new format is four times as wide and four times as high (for a total of 16 times the pixel resolution) as existing HDTV, which has a maximum resolution of 1920 × 1080 pixels. Because this format is highly experimental, NHK researchers had to build their own prototype from scratch. In the system demonstrated in September 2003 they used an array of 16 HDTV recorders to capture the 18-minute-long test footage. The camera itself was built with four 2.5 inch (64 mm) CCDs.

18 minutes of uncompressed UHDV footage consumes 3.5 terabytes of data and 1 minute of footage consumes 194 gigabytes. If 1920×1080p60 high definition video has a bitrate of 60 Mbit/s using current MPEG-4 compression technologies, then 4 times the width and 4 times the height will roughly require 16 times the bitrate. That would translate to 100 GB for 18 minute of UHDV, or 6 GB per minute. This would mean that a 12cm Holographic Versatile Disc at 3 micrometer separation of different colored tracks (with a capacity of 3.9TB) would be able to store roughly "11 hours of MPEG-4" compressed UHDV, compared to the 18 and a half minutes of uncompressed UHDV. Additionally, an eight layer Blu-ray disc (with a capacity of 200GB) would be able to store approximately 36 minutes of MPEG-4 compressed UHDV, compared to the 1 minute of uncompressed UHDV.

Like to see that tech on blu-ray even transferred slightly to fit if its to much info that mpeg-4 holds
I'm just tired of SD DVDS

no doubt can't wait to see if they develop hvd further.
