4K is the current mastering standard for the giant screen. Mastering in 2K or HD and upscaling to 4K in the media block of the projector is considered unacceptable for true GS content.
When possible, wedge tests should be mastered at 4K and viewed on a 4K 3D digital system; if not, left and right eyes should be viewed separately in 2D at 4K.
The level of detail seen in 4K is markedly different from 2K or HD. (4K has four times the resolution of 2K.) A shot that may have acceptable sharpness in HD/2K can look soft in 4K. Similarly, the on-camera sound recordist who was invisible in the low-resolution HD/2K version will jump off the screen in 4K!
