The specifications say that it can do 1080p @ 60fps and 4k @ 30fps. So no chance of a high speed full HD video output from GH4.

see carefully - that sensor (it might be a mod of it specifically for GH4 though - that is why it is "MN34230PL" and not simply "MN34230") can do "4k2k movie mode (30fps)"

also that sensor is 1.9 crop

Actual imaging area dimensions 17.6472 (H) mm x 13.3228 (V) mm (active pixel area) = 4656 (H) x 3518 (V)

and as "Number of effective pixels" = 4644 (H) x 3506 (V), we have :

((17.6472 * 13.3228) / (4656*3518)) * (4644*3506) = 233.7 mm^2

E-M1 has 4608 x 3456, so it is unfortunately does not reach 1.9 though, but rather 1.944 crop (228.6 mm^2)
