X680 HDMI port display information, according to the test:
#CM4 without eMMC (simpler, but you need a 32GB or 64GB micro sd)
#CM4 with eMMC 16GB or 32GB (requires additional steps)<span class="tb_red">CM4 with eMMC '''8GB''' is not supported, because the PIKVM V3 OS image file requires at least 9GB of space after decompression, 8GB cannot be flashed into OS to eMMC. For example: CM4004008 (RAM is 4GB, eMMC is 8GB) cannot be used with X680!)</span>
