Is any 2017 US LG 4K tv upgradable to ASTC 3.0 in 2018 ?

Asked by: RobxS
The LG SUPER UHD 4K HDR Smart LED TV - 75" Class (74.5" Diag), Model # 75SJ8570 and other 2017 models cannot be upgraded to ATSC 3.0 which is set to replace the current ATSC 1.0.Version 2.0 was intended to be backward compatible update but was eventually canceled in favor of the more significant 3.0 update which is planned to be an IP-based (internet protocol system). It's still an Over-the-Air system but built on the same protocols as most internet technology. IT is not compatible with with old systems and will require you to get new tuners to receive signals. The new chairman of the FCC presented a proposal that would allow for broadcasters to begin using ATSC 3.0 but still require them to offer an ATSC 1.0 version of their channels to ensure that legacy devices are not left behind. As ATSC 3.0 comes into use, the current DTV/HDTV broadcast system will continue to be used for transmissions for a period ot time so that your current TV will not become obsolete for a while. You just won't be able to access the advanced features offered by ATSC 3.0, however, once it is deemed that there are enough TVs in use that incorporate built-in ATSC 3.0 tuners, a fixed date will be set where only ATSC 3.0 Standards will be in use and that might not happen until 2020. Once the cut-off date has is reached, owners of remaining analog, HD and any non-ATSC 3.0 enabled ULtra HD TVs still in use at that time will need to have external tuners in order to receive network and local TV programming over-the-air. You will probably see a slow roll-out of ATSC 3.0 in both TV stations and TVs beginning late in 2017 if all goes well, however, as to when the current ATSC system will switch over entirely to ATSC 3.0 to be formally set is anyone's guess...^IFV
