A:AnswerYes, you need some sort of internet connection to connect the tv to Roku and the other apps.
We connected ours through WiFi, but there is an Ethernet input on the back of the tv.
A:AnswerHello, thank you for your interest in this TV. The TV has one HDMI 3/ARC jack.
It also has an optical digital audio and a headphone audio out, so you can choose any of these options to connect your Soundbar.

A:AnswerIt was reported here that the Insignia NS-55DR620NA18 does not support 24p. Here are my findings after thorough research:
1. I called Insignia twice different times to avoid the same representative.
2. Both representatives stated unequivocally the Insignia NS-55DR620NA18 4K UHD TV indeed displays 24p.
3. I am including two photos of my Insignia NS-55DR620NA18 showing 24 p from two different blu ray players, 4K and conventional non 4K.
4. The one from the 4K in the upper left hand corner shows 4K/24p with HDR below it. The player is Sony UBP-X700 currently sold by Best Buy.
5. The second one from the non 4K player in the lower right hand corner shows 23.796. The player is a video/audiophile once a top of the line from a very well known high competitive brand.
Thanks
