“What's the difference in the Sony dh750 and the dh770? They are almost identical”

• This one has more power and it is HDCP2.2 compliant, which will let you watch protected 4k content. The 750 is not for 4k. Some commenters are saying it is, even ones from Sony Talks, but Sony support as well as other sites say no.
