  • Rated 5 out of 5 stars

    Wonderful

    It's wonderful. Let me start by clarifying, I have 10 TVs. They are a combination of Sony, Samsung, LG, and TCL. This is my first Roku branded TV. As someone with several streaming subscriptions, I fell for the Roku platform years ago when individual brands struggled with licensing of the various services for their own platform. This TV was replacing a TCL TV that had the Roku platform. I have Roku sticks or other Roku devices connected to my other TVs. I'm pleasantly surprised by the audio quality. The bass levels are deeper and the audio clearer than what I would expect from a slim form TV. This was great for me, since it will be located in the bedroom where I won't end up adding a soundbar. The picture is bright and vibrant. The details are crisp and clear. I was expecting this considering the class of the TV. The menu system is snappy and quick and easy to navigate. There are many adjustable picture and audio settings. I specifically love the ease of getting to the Sleep function. Installation on the wall was easy and it fit my existing slim VESA wall mount. I will probably buy the Roku Pro wall mount just so it sits even more flush to the wall. The cable routing was thoughtfully designed and allows for a recessed outlet behind the TV or routing the cable down to a regular height outlet. I also have a Samsung Frame TV, which also sits flush to the wall, but that TV includes a large control box attached to the TV by a thin cable. This TV does not require such an additional box, so all control functions are built into the TV. The remote is great. The buttons light up when the remote is moved, which again, is great for the bedroom or dimly lit areas. The buttons are also soft press. This replaces the clicky-buttoned remote that came with the TCL. The remote is also chargeable, so no more looking for replacement batteries. The only con I can see is the price. Currently listed at $899 for a 55 inch TV, there are other well-known brand options. But the picture, audio, and software platform make it worth the price.

    4.5+ Stars

    This Roku Pro Series 55 inch has a beautiful bright picture. Even without upgrading Netflix to 4k the picture quality is enhanced. If you are using the television speakers the sound quality is also impressive. Setup is fast and easy, I was able to do so by myself quickly. I sometimes use Bose Quiet Comfort headphones and once connected/paired the television will automatically switch off sound and send only to the headphones. The reason I say 4.5+ stars is because the one drawback was the remote will not control my Polk Audio soundbar. The Roku 4k stream sticks would but this television is meant to work with other Roku products. You can connect other soundbars/sound systems, however you will be using the other remote. If the television is updated to pair with other sound systems this television becomes an automatic 5 star.

    Great looking with well thought-out features

    Picture quality is great with very dark black levels and very bright screen reduces glare from ambient light sources. I hung mine on the wall using the official Roku hinge mount and that worked very well in spite of my wall not being super flat. I used a DirectConnect wall box to mount the power outlet and store cables. At minimum you'll need a recessed power outlet for this type of install. There are cable management channels with built-in velcro straps. I had it on legs for a week and those are very sturdy as well. All in all you can tell a lot of thought and industrial design went into putting this series on the market. The built-in speakers sound great. The only disappointment is that the V2 remote has no headphone jack, but I just bought an extra V1 remote and it paired up with no problem. Highly recommend!
