Advertisements I couldn't care less about 4k, but HDR makes a noticeable difference and I've never seen a TV that's HDR and not also 4k, so it is what it is. The next model up of TCLs (6 series) has much better reviews on picture quality and similar. You can find the 55 inch for $600ish ($584.99 with free shipping on Amazon right now), see if you can find one to look at in person if it's more to your liking. If it's going to be a smart TV (and nowadays, that's all you can find) I much prefer a Roku smart TV to anything else. The Samsungs have really nice picture for the price too, but I despise their smart-tv app platform, and I find even just changing the inputs with a different remote (i.e. the Tivo remote) to be annoying. The one I got around Christmas has a stupid metal touch-pad style remote. I leave it behind the TV in case I ever need it but otherwise avoid it as much as possible. If you don't mind juggling two remotes or putting up with the annoyance whenever you want to switch back to the Tivo from an app or another streaming device, then it's fine, but I won't buy another Samsung TV any time soon. Also, don't forget Prime "Day" starts Sunday night depending on your time zone, and there will very likely be TV deals.
