The HDMI cord is too short for streaming player to sit directly in front of tv thus I have to get up and go closer to TV for remote to work. Will any HDMI cable work? Does Roku make a longer one? Would probably go with a different streaming device because of this.
What device and what kind of TV? If it's a 4k capable device connected to a 4k TV then you'll need a high speed cable. If either of those isn't true, then pretty much any cable will work. For what it's worth, I get my cables at the dollar store and I've never had a problem, but I don't need 4k. You will have fewer problems if you use the shortest cable that you can.
