Dolby Digital Plus passthrough from TV to HT over optical cable


Novice Member

i have read alot of threads online regarding sending 5.1 surround to a Home theatre through optical which seems to be limited to DD .

My situation :

Gaming PC connected to a Hisense 4k TV via HDMI 2.0
Hisense - 43" Class (42.5" Diag.) - LED - 2160p - Smart - 4K Ultra HD TV - Black

Home theatre i want to buy is philips HTB3570/40
Detailed specifications on HTB3570/40

I donot want to use HDMI (ARC) since it introduce lag and the home theatre only support HDMI 1.4

My question :

Since the TV states the it uses Digital Dolby Plus , and The HTS can encode/decode digital dolby plus . does this means that using an optical cable will work and i would get surround from my favorite games ??

Is there a way to force the VGA to sending the audio in DD+ , or is it the TV that does this Conversion automatically ?

thanks in advance

If you want to optimise the audio from your Game PC/Console look for a system which has multiple HDMI Inputs - the TV will not pass DD+ via its ARC or Optical Out.

TV's are not the ideal 'Hub' of a system where you want to optimise audio.
