AppleACPIPlatform is not correct for Yosemite. Could be an issue.

Restore to vanilla.
 
only roll back shows 10.9.5 in muiltbeast

Not sure what you're saying. Your AppleACPIPlatform.kext is from Snow Leopard.

Restore to vanilla... means run the Yosemite installer to restore it (because you didn't create a backup before you overwrote it).
 
can i just install the vanilla More AppleACPIPlatform.kext, instead of reinstall it all over again?
 
ok so i did a clean install, and used multibeast. i tried the HDMI again and now when i plug the cable the screen turn black then back to normal again, instead of flicker the other time.

here the output of the of the clean install

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)

Please read post #18 carefully... "in your profile/signature"...

You will need to know chipset (6-series or 7-series).
