The Good: Roku TV delivers the simplest, most comprehensive smart-TV experience on the market. A superb user interface puts its thousands of apps and streaming video on the same plane as regular TV. It's also less expensive than just about any other smart TV. The Bad: Competing entry-level TVs, namely Vizio's E series, deliver better image quality for a similar price. Sparse picture controls and no Ethernet port. The Bottom Line: Despite its "good enough" picture quality, the Sharp Roku TV is one of our favorite entry-level sets, thanks to an awesome smart-TV suite and rock-bottom pricing. Typical smart TV systems aren't any smarter than 5th graders, but Roku is Jeopardy Champion. Those systems offer limited app selection, complex interfaces, extra features you don't need and almost never get updates. Roku offers all apps you could want and then some, plus full customization, menus a child can use, better search and constant updates. \t \t \t \t \tThat's why, if you don't have a Roku TV, we recommend -- like, you know, -- and ignoring the TV's built-in apps altogether. And that's perfectly fine for your main living-room TV, which probably has a device or ten already connected. \t \t \t \t \tTVs with Roku's smarts built-in, like the Sharp LC-LB371U series, are the only TVs to which we don't recommend hooking a separate streamer. Heck, if you cut the cord you might not even have to connect anything to this TV. Thus, it makes a great secondary or bedroom set, or a prime primary TV for people who value streaming and convenience above all else. \t \t \t \t \tOn the other hand this Sharp, and other 2015 Roku TVs I tested from TCL and Insignia, can't match the image quality delivered by the similarly priced . If picture-for-your-dollar is your main priority, then by all means go Vizio (just don't forget to buy that streamer, too). But if a "good enough" picture is good enough for you, and you're in the market for an entry-level TV with genius-level smarts, then it's Roku all the way. \t and alternate model information: I performed a hands-on evaluation of the 43-inch Sharp LC-43LB371U, but this review also applies to the 50-inch Sharp LC-50LB371U. According to Roku the two should have very similar picture quality. This series of Sharp Roku TVs is . \tI also performed hands-on reviews of the and the Roku TVs at the same time. All three brands of Roku TV have very similar performance; see the Picture Quality section for details. Since the design and features are very similar between the three brands as well, they all received the same ratings, and the text of these reviews are largely identical.Design \t \t \t \t \tThe Sharp LC-LB371U we reviewed hands-on looks unassuming to the point of generic, with a thin, glossy black frame and dual (dueling?) Sharp and Roku TV logos. It sits on a pair of legs that, unlike those of the TCL version, aren't splayed that far to either side. For that reason it's a better candidate for narrower tabletops than the TCL. \t \t \t \t \t \tWhere the design of the Roku TV stands out is in its remote and onscreen menus. \t \t \t \t \tThe Roku TV remote is the simplest full-function TV clicker on the market. Patterned after the pint-size remote used on Roku devices, it includes only the trademark purple cursor control, a minimum of other buttons required for menu navigation and video control, and side-mounted volume\/mute. In a slight bit of differentiation from TCL's clicker, the Sharp and Insignia Roku TV remotes have a glossy finish and dedicated buttons for game mode and the sleep timer. \t \t \t \t \t \tThe remote also has four branded app shortcuts. It's great to have one-button access to Netflix and Amazon Instant, but I'd prefer more popular apps like YouTube or Pandora to Rdio and M-Go. \t \t \t \t \tUnless you use the number keys to select channels, you'll likely never miss the buttons Roku's clicker omits. That's because it has the best menu system on the market. It uses plain language and thorough explanations to make using the TV a piece of cake. \t \t \t \t \t \tThoughtful touches are everywhere, starting with initial setup. After signing on to Wi-Fi, it asks you to link the TV to your Roku account at Roku.com. There, on your PC, tablet or phone browser screen, you're presented with a list of apps (Roku calls them "channels") installed by default, and you have the option to immediately remove them or add more. After the link succeeds, the TV updates with the apps you've chosen on the website. If you already have a Roku device and account, Roku also automatically installs those apps on the TV too (you'll still have to sign-in to each one separately, of course). No other smart-TV system has as robust, useful and simple a link to a companion website; you can search for, add, and delete apps there as well as on the TV itself. \t \t \t \t \t \tDevice setup is equally simple. The system first asks you to turn on all your connected devices and plug them into the TV. Beginning with HDMI Input 1, the TV shows what's playing on each and asks you to name them from a list of typical devices, such as Cable Box or PlayStation, and choose "none" for unused inputs. These inputs then appear at the top of the home page, like any other app. You can move them, rename them, or remove them entirely. \t \t \t \t \tAfter everything is set up, the home screen appears, which should be familiar to any Roku veteran. The big app tiles are there, along with easy access to Search, the Channel Store and Settings. The most obvious difference is the presence of extra icons along the top, one for each input device you've set up. Highlight an input and the tile activates to show a live preview of that source; for example the live TV feed from your cable box or the screensaver from your game console. You can also move inputs around on the grid, just like any other app. \t \t \t \t \tDepending on how much you use apps as opposed to watching TV from a traditional source like a cable box, you might either love the app-centric Roku TV home page (I do) or wish for the option to skip it and go directly to an input by default. Happily, Roku TV gives you that option. Under Settings > System > Power > Power On, you can choose to "Always power on to..." the Home screen (the default), the last-used TV input (standard for most TVs), or directly to any input, such as the cable box. \t \t \t \t \tOther helpful additions include the full-screen contextual tips, a helpful intro video, a strong array of closed-caption options, and the nerdy ability to change themes from the default Sharp black. \t \t \t \t \tThe interface isn't flawless, though. No matter which theme you install, the Roku TV can still can appear dated compared with the whiz-bang environments of a Samsung, or Android TV from Sony or Sharp. That's a minor price to pay for great utility in my book, and I'd argue that app-centric phone and tablet interfaces (see: Android and iOS) are also correct to favor the tile approach. It just works. \t \t \t \t \tAnd while Roku doesn't push its own content nearly as much as some platforms (Apple TV, Amazon Fire TV, and to a lesser extent Samsung), there are three prominent menu items I don't love. Movie Store and TV Store go to M-Go's content, while the News option leads to AOL On. (Happily, they can be disabled under Parental Controls.) There's also a prominent ad to the far right of the home page that appears when you begin browsing inputs or channels.Features \t \t \t \t \t \tLet's face it: this is an entry-level TV. No fancy local dimming, high refresh rates or 3D will be found here. \t \t \t \t \tThe TV lacks the awesome headphone-jack-on-remote and voice search features of the Roku 3 boxes, although there is a headphone output on the TV itself, and you can use the Roku app for iOS and Android to search the TV via voice. The clicker is standard infrared, so it requires line of sight to the TV. \t \t \t \t \tIf you're a cord-cutter interested in using the built-in antenna, you'll be disappointed to hear the set lacks a grid-style channel guide, an extra found on Samsung TVs (but not on Vizios, for example). Selecting channels directly is also a bit more time-consuming because the remote lacks a number pad -- instead Roku offers a list of channels you'll have to scroll through. \t \t \t \t \tThe USB port is compatible with videos, photos and music, and the TV itself has DLNA, allowing you to stream those files over a local network as well. Both of those feats are accomplished using the Roku Media Player app. In my tests it worked very well, streaming a variety of files and formats over our network, and via USB, without any major problems. Hardcore file-streamers might still want to use Plex or another similar app. \t \tSmart TV: The TV behaves just like a Roku box, and that's a good thing. It's not quite as snappy as a Roku 2 or Roku 3, but still very quick to navigate and launch apps. Its design is simpler and more intuitive than any other smart TV, including Samsung's 2015 Tizen, LG's Web OS 2.0, Android TV and Vizio. All of those have their strong points, and most look sleeker and more high-tech than Roku, but none are as dead-simple or customizeable. Roku TV's interface allowed me to get to what I want -- streaming videos and TV shows -- with the least amount of fuss. \t \t \t \t \tOther smart TV systems bring butter knives to the app coverage gunfight, while Roku shows up with a nuke. Many of its 2,000-odd app choices are either chaff or so specialized you likely don't care, but none of the big names go missing either, unless you count proprietary content sources like iTunes or Samsung's app store. HBO Now is the biggest no-show, and I expect that to arrive soon as well. \t \t \t \t \t \tNo other smart TV aside from Samsung's gets HBO Go, for example, and even Samsung -- the leader in smart TV app selection -- is missing numerous major apps that Roku has, like Sling TV, Google Play Movies and TV, Showtime Anytime, Watch ESPN, Comedy Central, CBS All Access, Amazon Music, Rdio and literally thousands more. \t \t \t \t \tThe apps themselves are usually the most up-to-date versions, although not always. Roku TVs' versions of Amazon Instant, HBO Go and Showtime Anytime are old-school, with basic thumbnails and blocky text compared to the sleeker versions found on many other systems (they work fine though, and provide access to all the same content). On the other hand, Roku TV does have the latest Netflix (complete with profiles), YouTube, Hulu Plus and Sling apps, among others. Roku also, unlike most smart-TV purveyors, has a history of updating its software regularly, even on older products. \t \t \t \t \t \tCase in point: 2014 Roku TVs got the that added My Feeds as well as app search. The former shows when certain new releases you choose to "follow" arrive on streaming services (complete with pricing), and the latter is just a dedicated search window in Roku's channel store. Both are relatively small additions but nonetheless help improve the overall experience, and of course both are available on 2015 Roku TVs too. \t \t \t \t \tThe Roku platform offers the best cross-platform search anywhere. It hits Netflix, Hulu Plus, Amazon Instant, HBO Go, Vudu, Crackle, M-Go, RedBox Instant, TWC and other sources. One of the big advantages of cross-platform search is that you can save money by using it: if you subscribe to Netflix, Hulu Plus, Amazon Prime, HBO Go and so on, search for a show or movie before you purchase it and you may discover you can get it for "free."
