Good reviews at Amazon: https://www.amazon.com/Hisense-55H7B2-55-Inch-Ultra-Smart/dp/B00XMUU4QK and it’s a good price for a refurbished product. However, from what I read you get a 4 year warranty if you sign up within 3 months of your purchase. That’s a huge selling point to purchase a new item, if true.
Guessing this doesn’t support the HDR of the new Xbox One S?
Probably not. TVs with HDR will be called out as having that technology.
They should tell you if it has HDCP 2.2 if not it isnt even worth buying unless you just want a TV for a spare room. I see someone asked about HDR - No 2.2 = No HDR.
Regarding HDCP from the Amazon website:
Two inputs are HDMI version 2.0 with HDCP version 2.2 supporting 4K content up to a full 60 frames per second, firmware update needed. The other two inputs are HDMI version 1.4a with HDCP version 2.0 supporting 4K content up to 30 frames per second.
