What are 32k and 64k in projector?

The difference between the projector 32K and 64K is in the level of resolution and the number of pixels, 32K resolution is 30720*17820 pixels, while 64K resolution corresponds to 61440*35640, 64K resolution is actually four times the pixels of 32K, so the picture will be clearer and the details more prominent. However, the maximum resolution of the current projector is only 4K, and larger pixel images need to be projected jointly by multiple projection devices.
