Ranked in these QuestionsQuestion Ranking
Pro Great for HDR content
The VIZIO M50-E1 performs well for HDR content thanks to its black levels, high native contrast ratio (5606:1), and wide color gamut — all three of which are essential to a great HDR experience.
Pro Decent performance in bright environments
The M50-E1’s panel has a semi-gloss finish for diffusing the light across the screen evenly to decrease light intensity. This, along with its ability to get quite bright (practically, it peaks at ~400 nits for HDR and can maintain this level of brightness), means that it is good at handling reflections and performs decently in bright environments.
Pro Great black levels and uniformity
The black levels of a TV affects the viewer’s perception of other colors next to it. If the black levels are not deep enough and doesn’t remain uniform across the screen, the overall picture quality will look “flat” without much depth. The M50-E1 handles this extremely well with only <1% deviation (across the entire screen) from what a pure black screen should be — this results in a significant gain in its native contrast levels, thereby increasing the picture quality.
Pro Great for dark rooms
The M50-E1 is great in dark environments / cinema-like settings. The blacks will look richer and deeper allowing for better reproduction of dark highlights and scenes in movies, which makes it particularly great for movies with many black highlights/scenes (such as Interstellar) where this is immediately noticeable even to undiscerning viewers.
Pro Can be remote-controlled from smartphones/tablets
The M50-E1 runs on Vizio’s SmartCast OS, which has a remote app for iOS & Android capable of controlling the TV.
Pro Great color reproduction
The color gamut of a TV refers to the range of colors the display can reproduce — the wider the color gamut, the more colors it can display, and the better the overall picture quality will be. This is extremely important for HDR content because it requires a much wider color gamut than SDR content. The M50-E1 has a wide color gamut and have no issues with accurately reproducing the colors necessary for true HDR.
Pro Supports both HDR10 and Dolby Vision
There are two different formats for HDR — HDR10 and Dolby Vision. Some TVs support only HDR10 and can't play Dolby Vision content. The M50-E1 supports both HDR10 and Dolby Vision, giving it the ability to play any HDR content in 2017.
Pro Interface is ads-free
The user interface of modern smart TVs can include some advertisements similar to those on the internet or in a mobile app. The M50-E1 does not include any.
Pro Comes with Chromecast built-in
The M50-E1 comes with a built-in Chromecast. You can easily cast media from any device with Chromecast support.
Pro Excellent for watching sports
The Sony X720E has all the bits and pieces needed to deliver the excellent experience of watching sports and other fast-paced content. The TV has good control over its motion blur, excellent color uniformity, and wide viewing angle.
The X720E needs only 7.5 ms for its pixels to change their color; as a result, fast-moving objects don’t leave long trails on the screen, meaning that the motion blur effect is almost negligible.

The maximum color deviation of this TV is below 2.5%, which means that the TV can sustain stable and uniform colors throughout its screen. The X720E has the best color uniformity in its range.
Pro Great for bright rooms
The combination of reasonably high peak brightness and semi-gloss screen finish allows this TV to deal with reflections and glare efficiently. Its 340 nits of brightness are more than what its direct competitors, including The VIZIO M-series and Samsung MU6300 offer. Furthermore, as the X720E diffuses up to 97.6% of ambient light, it does not suffer from reflections.
Pro Excellent viewing angles
The IPS panel of the Sony X720E gives you an extra bit of flexibility when it comes to finding a good viewing spot as its maximum viewing angle is 41 degrees; a double of what the competitors with VA panels can offer.
Pro Ads-free main interface
The main interface of the smart OS does not feature advertisements or sponsored content.
Pro Excellent for upscaling
This TV does a fantastic job when it comes to upscaling low-resolution content. In a nutshell, it can upscale 480p, 720p, and 1080p content to 4K resolution while preserving details and sharp edges. Great for those with a collection of old DVDs or Blu-ray disks.
Pro Well-rounded inputs
Regarding connectivity, this TV is has everything you'd currently want. It has three HDCP 2.2 compliant HDMI 2.0 ports, digital and analog audio output ports, and an Ethernet port. Additionally, as the TV has a composite input interface, you can enjoy playing your retro consoles, such as Nintendo or Sega without having to go through the hassle of signal conversion. HDMI, USB, and analog coaxial ports are situated on the side of the TV so you won’t have any problem accessing them even if it’s mounted on a wall.
Pro No problems with image retention
Unlike the majority of OLED panels, this LED TV does not suffer from image retention problems. You can leave the TV on for long periods without having to worry about pixel damage.
Pro Suitable for viewing up-front
The reasonably small panel size of 43-inch means you can still be comfortable looking at the screen up close. Therefore, you can conveniently use this TV as a computer monitor and sit as close as 2.2 feet away from it.
Pro The stand does not take up too much space
The 43-inch model of Sony X720E does not take up too much space on a work desk as the TV comes with a compact, 9.4-inch by 21.9-inch stand.
Pro Makes an excellent computer monitor
The Sony X720E makes an excellent computer monitor because it can smoothly display sharp and crisp images since the TV has full 4:4:4 color support, short input lag, and well-handled motion blur.
The full 4:4:4 color support allows the X720E to process non-compressed, computer-generated video inputs. Therefore, the TV can display sharp and crisp images, without any detail loss. This is especially noticeable while working with text and other vector graphics.
Additionally, the TV’s input lag of 19.7 ms ensures that it takes less than 20 ms for a TV to display an image change after you press a button. Such delay is almost unnoticeable to a human's eye.
Pro Excellent for console gaming
The combination of handled motion blur and low input lag makes this 4K60 TV a great companion to the latest generation consoles, like the Xbox One X, PS4 Pro, and Wii U. Additionally, the TV’s full HDR support allows you to fully experience HDR-enhanced games such as World of Tanks, FIFA 18, etc.
Con Local dimming is lackluster
Local dimming is the TV's ability to dim areas of the screen for deeper black levels and better contrast — they are separated into different dimming zones, where each zone can be individually dimmed as needed. While the M50-E1 has local dimming, the benefits of it is rather lackluster, offering only an ~200 increase in contrast ratio when turned on (5606:1 native contrast, 5861:1 with local dimming turned on). This is enough to make a noticeable difference to the discerning viewer in dark environments, but doesn’t do much in brighter environments.
Con Mediocre sound quality
The sound quality on this TV is mediocre and curved towards the lower frequencies, causing it to sound too bassy to some people. Because of this, its soundstage isn’t very wide either. There is also noticeable distortion that gets worse at higher volumes. An external audio setup — such as a soundbar — is highly recommended in order to get the most out of this TV.
Con Interface can be sluggish and slow
The interface of VIZIO’s SmartCast OS can sometimes be sluggish; some users have reported experiencing choppy animations, frame drops when browsing through the menu, and slow response to input/selection.
Con Poor viewing angles
The picture quality suffers from some degradation when viewing from an angle, as typical of a VA panel.
Con Lacks TV tuner
The M50-E1, along with several of VIZIO’s latest TV lineups, does not have a TV tuner built-in. If you plan to watch local over-the-air broadcasts, you will need to purchase a TV tuner separately.
Con Dark scenes look shallow
Due to the really low native contrast ratio of 907:1, dark scenes look washed out if the TV is placed in a dark environment.
Con Requires an external power brick
Both the 43-inch and 49-inch models of the Sony X720E have large and bulky external power bricks. Bulky PSUs can be a hassle to deal with especially if you’re mounting your TV on a wall.
Con Lacks Dolby Vision support
When it comes to HDR content, the X720E cannot display Dolby Vision-compliant media as it is only limited to HDR10 content.
Con Can’t fight judder in 60 Hz signal
The Sony X720E can't handle judder in 24p content sourced from the 60p/60i devices, like a cable or satellite box, or Apple TV. Such content contains so-called '2:3 judder' which means that the frame distribution among the timeline is inconsistent.
Con Not suitable for competitive gaming
While this TV has noticeably smaller input lag than the overwhelming majority of TVs on the market, it still can not compete with rapid TN monitors when it comes to fast and competitive computer gaming.
Con Can’t unleash full potential of HDR content
Even though this TV does support HDR10 media, the low HDR peak brightness, poor native contrast, lack of local dimming, and lack of wide color gamut severely limit the quality of HDR playback. Even some lower tier TVs will produce higher quality HDR images.
Con Built-in speakers don’t sound right
The X720E comes with an integrated 20W 2.0 stereo speaker system. While it can get pretty loud, peaking at the sound pressure level of 100 dB, the quality of sound is very weak, especially when it comes to bass. The speakers sound unclear and muddy.
Con Non-intuitive smart OS
Unlike other Sony TVs, the X720E has a custom, Linux based operating system which runs the Opera TV application store. The OS is unintuitive and confusing to use.
