Although the image quality is just "good enough," the S405 series is still an excellent choice for budget buyers focused on streaming and simplicity.

  • +

    The TCL S405 series are among the least expensive 4K TVs on the market. Roku TV delivers the simplest, most comprehensive smart TV experience on the market. A superb user interface delivers thousands of apps and the most 4K video of any system.

  • -

    Worse picture than competing Vizio TVs. 4K resolution and HDR don't deliver a substantial improvement in image quality.

When not viewed through the lens of its far superior P-Series model, the TCL S-Series of 4K TVs offer capable but unimpressive performance for a very low price.

  • +

    Quite inexpensive. Roku TV features. Decent picture quality.

  • -

    Slightly skewed colors. Roku TV remote doesn't have enhanced features.

The TCL Roku 49S405 is more than just an affordable 4K set; it’s also a great smart TV, with plenty to offer movie lovers, gamers and cord cutters.

  • +

    Decent 4K quality with basic HDR support, Better-than-expected audio quality, Short lag time, Great sub-$500 price

  • -

    Could use more HDMI and USB ports, Backlighting has unwanted shadows

Bought this TV due to its price. I was skeptical at 1st, but now that I have it, I'm happy I bought it. I tested the TV with an Xbox One S and PS4 Pro. Everything looks fantastic !! Having a built in Roku is genius. Right out of the box you have so many apps at your fingertips.

When I turned the tv on for the first time, the remote did not work. The tv was stock on the "Lets get started" page. I called customer support and after 45 minutes of trouble shooting they finally agreed to send me a new remote. I ended up smacking the remote a couple times and it started to work.

Too many video snobs out there! FOR THE MONEY, this is a remarkable TV. Easy setup and the Roku interface works great. Look up the color settings on the RTINGS website and download the Roku app. You can really dial in the color to your own liking.

Great tv and even better with my new Xbox one s ;) if the one X's were less expensive it would have been those but the TV is perfect just makesure you have 50' of space for it and it's not totally flat but it's only a little part of the bottom back that sticks out about an inch to inch and a half...

TV looks and works great thus far. Easy set-up, and I love the built in Rodku functionality! It's easy to access existing music and Rodku set-up, which makes the process that much easier. I was planning to buy a sound bar, but the built in sound is actually pretty good.

Ok so I was looking around for a new 4k TV for gaming and this is what I stumbled upon. No lie this TV is absolutely incredible, great value and the picture is insane. 4k ps4 pro is incredible on this TV well worth the buy!

23 September 2018

The new TV is just awesome; has clarity and huge viewing possibilities; the price was pretty good for a unit this size. Hookup was easy; the only problem I have is the volume control located on the side of the remote. Appears that my hand hits it every time I attempt to use it.

20 May 2018

Seriously, you can't beat the quality for this price. I'm a cord cutter and it was two days before I even realized the TV remote doesn't have numbers for changing channels. Everything I use this for is browsing through apps on the TV. The price is absolutely unbeatable for the quality.

My Niece recommended this tv to me. I saw the tv and all the features included and the price so I figured I would try it. Let me say I am blown away by this tv. The image clarity is astounding I love watching shows and movies in 4K.

Want to like it more but the set up and function is not as intuitive as it should be. Needs to have easier integration with Alexa and other devices. Picture is good but not as good as I was hoping.
