Does anyone know why Samsung would specifically recommend a CAT 7 cable for this & similar TVs?
I would assume that the internet service into most homes would be CAT 6 or lower.
I just don't see how adding a CAT 7 cable at the end of that internet service (between the Router & the TV) would add any benefit - unless the cables before it are all also CAT 7
And no one would replace all of their existing cables just because a TV requires CAT 7
LG TVs say this too, but they're using ethernet adapters that only do 100Mb like Samsung. CAT7 was made to support 10Gb over 100m distances and isn't even needed for 10Gb since 6 supports it for 55m and 6a supports it for 100m (and most people don't run 10Gb links across their house).
The only thing I can think of is that they're assuming in-wall runs very close to AC power lines and the extra shielding might be beneficial. CAT 5e is sufficient for gigabit and 2.5G and once again, these TVs all use stone age adapters so a ripped up CAT5e cable with exposed copper probably won't show any speed drop.
