If you notice, the Roku 4 is no longer featured on Roku's site. One of the drawbacks for that model was lack of HDR capabilities. I have the Roku Ultra and it definitely has an option to use HDR onto your HDR capable TV. Note: My TV has HDR set to 'on' so this might be something to take into consideration. The Roku won't magically provide HDR to a 4K TV that doesn't support HDR.
Sorry, there was a problem. Please try again later.Yes it will work. I use it on my Vizio 4K tv and my Roku Ultra and I receive 4K on my Netflix account using my Roku UItra.
Sorry, there was a problem. Please try again later.I've used it! It's one of Roku's top suggestions for 4k viewing when you use their "spotlight on 4k" app! Gorgeous pictures!
Sorry, there was a problem. Please try again later.the ultra will work with VUDU in 4k. it does not however pass bitstream over dd+ so you cannot take advantage of VUDU's dolby atmos broadcasts.
Sorry, there was a problem. Please try again later.I had big problems with Ultra. I still have the previous 4k ROKU that is bigger and better because it does not fail or overheat.
Sorry, there was a problem. Please try again later.
