If you can't quite afford the amazing TCL 6-series TV (on sale at Best Buy for $550 to $800), stepping down the TCL line will save you money -- albeit with compromises on picture quality. This 49-incher gets its smarts by way of Roku TV and includes 4K and HDR. CNET called it "an excellent choice for budget buyers focused on streaming and simplicity."

This entry-level Samsung LED TV serves up a 50-inch screen with 4K and HDR.
