What new tv sets are you all buying to pair with your Roamio? I kinda realize that I dont need a smart tv and will probably not use that feature but 99% of them have it built in now. Id like a 50 to 55 inch to replace my 40" thats over 10 years old. Is 4k and HDR worth getting? I know the TiVo can only output 1080 and I dont have an ultraHD blue ray player yet.
