How to watch 4K Ultra HD(UHD) Blu-ray?
You need three things: an Ultra HD(UHD) Blu-ray player, an Ultra HD TV and some 4K UHD discs.
First, you’ll need to make sure your TV supports HDMI 2.0 standard or above. Most of TVs released from last year to now have supported HDMI 2.0, but the old models released before 2014 might not support. Check your TV manual or Google the model number to find out – the even newer HDMI 2.1 standard should be fine.
Also, only the newest TVs released after 2016 support HDR technology. That’s because HDR requires TVs that can display more colours and have a higher peak brightness.
You can still enjoy Ultra HD Blu-ray without an HDR-ready TV, but you will not enjoy the benefits of HDR.
Finally, there are only a few Ultra HD(UHD) players for purchase in market – The still impressive Panasonic DMP-UB900. The newer, equally excellent Panasonic DMP-UB700. The slightly cheaper, but still very good, Samsung UBD-K8500.
Have the 4K video content in Ultra HD(UHD) Blu-ray been encrypted?
Yes, 4K Ultra HD(UHD) Blu-ray uses newer AACS 2.0 encryption method than before.
