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.
Glen wants to know how much resolution a DVD really has compared to a Blu-ray. Scott says DVDs are standard definition which is 720x480. Blu-ray can be 1920x1080 and above. How will it upscale? Scott says the newer his tv, the more it will upscale. If he buys a 4K TV, it will be about 10 times the resolution. The more upscaling it does, the more problems can happen. Scott says he may consider streaming from PBS. It may be in HD, rather than SD.
Scott joins us to talk about streaming in 4K and how it isn't really 4K quality. You would need a 4K TV, but it barely reaches Blu-ray quality. So you end up spending extra money for the same quality you have from your Blu-ray player. Samsung, though, has a new line of 4K TVs that offer high dynamic range (HDR) quality. The problem is, there are five different standards for 4K HDR, including a standard by SMPTE and 4 proprietary standards like Dolby Vision. So Scott says it's still not time to buy 4K. But soon you won't have much of a choice.
