Tom wants to know how much better 4K Blu-Ray is over standard blu-ray. Should he upgrade? Leo says that 4K is 4 times more resolution than standard Blu-ray, but the big difference is the higher dynamic range (HDR). The colors are bolder, the blacks are blacker, and viewers can see more detail in extreme brightness and low light. But everything in the chain has to support 4K. The TV, the cables, the player. But Leo believes we're finally at the end of the road for physical media. So if anyone wants to upgrade to 4K for one last copy, do it because they want the HDR upgrade.
Jeff has a 10-year-old HD TV and he's thinking of upgrading to 4K. A TCL 65" with Roku built in. A good buy? Leo says he'll likely need a decoder box to work with the cable subscription. But will he get 4K? Well, that depends on his cable. And even then, no live channels really broadcast in 4K anyway. He can stream it through Netflix and others, but it requires a faster internet connection. One thing he can do is get a 4K Bluray player.
Isaac has a nice Sony home theater system. But with 4K, he wants to know if the difference in quality is worth rebuilding it in 4K. Leo says that Blu-ray is not only 4 times the resolution as 1080p, it also has the high dynamic range and that's more important. If his home theater supports HDR, then there's no problem. If not, he may want to think about it. Moving forward, he can start picking up UHD HDR Blu-rays for his collection. Billy Lynn, Master and Commander, the BBC Earth series — all are excellent.
Ron wants to know if it's worth the money buying a 4K Blu-ray player. Leo says only if he's planning on buying a 4K TV and only if he's planning on getting one over 55" in size. Then he'll want not only a UHD Blu-ray player, but also a 4K TV that supports HDR.
Leo bought the XBox One S with a 4K Blu-ray player, but it meant that he had to buy a 4K TV. So he bought the 65" LG B6 OLED 4K TV. Leo says it's stunning how thin the TV is. But then he had to buy the Denon 910 because the UHD signal couldn't pass through his old AV receiver. That also meant he had to buy cables. Scott says that Leo didn't have to buy new HDMI cables unless they were really old ones. Any HDMI cable from the last few years should be able to handle the 18GB connection required. The real key is the ports on the AV Receiver.
