If you want a great HDTV, you don’t have to rob a bank. It’s true that they are expensive sets, but 51-inch HDTVs within $500 with superb picture quality, good connectivity, and other great features are available.

• TCL Roku TV 50FS3800
  People who need a feature-laden smart 51-inch TV within budget, this can be a fair choice with decent screen size. The 1080p display and 120 Hz refresh rates make it a good option with the Roku platform. The Roku Set-top box is pre-packaged, making a separate purchase of another set-top box irrelevant. A smartphone or laptop can also regulate the TV while using the Roku Mobile applications. The price is around $480, and the smaller versions are also there for those who need even cheaper models. Three HDMI ports, a USB port, and connectivity for devices from the home screen are available. Switching between connected devices, swapping channels, searching for series and movies or streaming media is possible with the help of only a few buttons. A simple panel with two-leg stand design and a slim 51-inch screen look nice and sober.
• Vizio E50-C1 Smart TV LED HDTV
  This 51-inch model is available at around $528 online and at even about $400 with some added discounts. It comes with a 1080p display and 120 Hz rate, along with three HDMI ports and one USB port for external devices and storages. This TV is also well suited for wall mounting. One of the best features is the local dimming that makes the contrast ratio much better than that of other models in this range. Auto-adjustable brightness, streaming media applications, and built-in WiFi compatibility are some of this model’s benefits. In this price, this particular model provides superior picture quality with great color accuracy and slim panels. The minimal-looking legs and tiny bezel make it a sleek design for small and simple space.
• Vizio e500i-A1 Smart TV LED HDTV
  An older but still relevant version for bargain-friendly costs (about $399). The 51-inch, 120 Hz LED panel with 1080p resolution is sober and provides user-friendly streaming media applications like Netflix, Hulu, Amazon prime video, Pandora, and Spotify. The LED zones can be activated as per the requirements, which comes with the auto-adjustable screen to compete with room brightness. The app launcher is helpful to bring you back to the place where you need to be while switching on the television set. This model has four HDMI ports and a USB port for external storage and devices. Besides, this is not as readily available as the former models as it’s an older version, and Vizio E50-C1 has arrived in the market as its replacement.
