A:Answer I'm not sure what you mean when you asked about multi system.
As a owner of this TV I can say you this:-
*This TV has 4K resolution (i.e four times the resolution of 1080P),
*It has video upscaling technology so even 720P or 1080P video looks much better on the screen with vivid colors and deep contrast ratio,
*Is capable of 3D and comes with 2 sony 3D glasses,
*Comes with couple of HDMI ports and a USB port for media input,
*Has wireless built in and some great apps (eg: netflix, youtube, hulu etc),
*Has a built in camera for skyping,
*Added speakers on either sides delivers perfect sound quality.
From my experience so far I would rate this TV 5/5.
Hope I answered your question.
