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 almost double than what its direct competitor, the TCL S405, offers. Furthermore, the X720E diffuses up to 97.6% of ambient light; thus the TV does not suffer from reflections.
Pro Excellent for console gaming
The Sony X720E is a great companion to latest gen consoles, like the Xbox One X, PS4 Pro, and Wii U because of its 4K60 support, low input lag, and motion blur candling capabilities.
Furthermore, the TV’s full HDR support allows you to fully experience HDR-enhanced games such as World of Tanks, FIFA 18, etc.
Pro Excellent for upscaling content
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 Ads-free main interface
The main interface of the smart OS does not feature advertisements or sponsored content.
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 the Nintendo and 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. 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. In comparison, the TCL S405 takes up almost 30% more table space.
Pro Excellent viewing angles
The X720E has excellent viewing angles because of its IPS panel, which gives you greater freedom than VA panels when it comes to finding a good viewing spot. In fact, you will only notice a minor color shift if your viewing angle is greater than 41 degrees.
Pro Exceptional picture quality
The X940E is the best LED TV of 2017, outperforming the Sony X930E and X900E in nearly every aspect. Its picture quality is top-notch for any kind of content and it can handle all sorts of use cases really well.
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 X940E has no issues with accurately reproducing the colors necessary for true HDR because its color gamut is one of the widest and only bested by some OLEDs.
Pro Virtually no reflections
The X940E's panel has a glossy finish, unlike the X930E which has a semi-gloss finish. This, along with its ability to get very bright, means that this TV is excellent at handling reflections — even in a bright room, the picture quality will remain more or less the same.
Pro Perfect TV for movies and HDR content
The X940E's performance can be considered on par with the OLEDs in this price range. It has everything necessary for true HDR: high native contrast (4941:1, can go up to 11634:1 with local dimming enabled), wide color gamut, great black levels and uniformity. Beyond all that, its panel is one of the best in the market — even in a bright room, this TV can still really shine because of how bright it can get.
Pro Great for dark rooms
The X940E shines in dark environments — it is great at reproducing dark scenes, making it suitable for enjoying media in a cinema-like setting. It performs extremely well in movies with many black highlights/scenes where this is immediately noticeable even to undiscerning viewers (e.g. Interstellar).
Pro Does not suffer from image retention
Unlike the OLED panels in this price range, the X940E has a VA panel and thus it does not suffer from image retention issues.
Pro Great ecosystem of third-party apps
The X940E runs on Android TV — normal Android apps from the Google Play Store (or other app stores) will work on it.
Pro Excellent performance in bright environments
The X940E has a practical peak brightness of ~1,100nits for both SDR and HDR content — this is by far the second brightest ever in a VA panel, only bested by the X930E. It can sustain this level of brightness when playing content and it will not have any issues with fighting light in bright environments thanks to its virtually reflection-less panel.
Pro Excellent 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 X940E handles this extremely well with one of the lowest deviation (<0.6%) ever in a non-OLED panel. This is measured across the entire screen from what a pure black screen should be, giving it significant gains in its native contrast levels thereby increasing the picture quality by a ton.
Pro Dark scenes looks great
The X940E can handle dark scenes very well thanks to its high native contrast levels, which clocks in at 4941:1 native, and it can go up to 11634:1 with local dimming enabled. This, along with excellent black levels and uniformity, gives the TV the ability to achieve great representations of dark scenes beyond most expectations.
Pro Local dimming is excellent
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. The local dimming on the X940E is the best in LED TVs of 2017 — it is capable of doubling the contrast ratios from 4941:1 to 11634:1. The only other LED TV with this capability is the VIZIO P65-E1, but its contrast with local dimming enabled is lower than the X940E's (at ~9.3k:1).
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 X940E does not include any, and it also has a feature for limiting ads in third-party applications.
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 Not compatible with Dolby Vision
When it comes to HDR content, the X720E cannot display Dolby Vision-compliant content as it is only limited to HDR10 content. Even though HDR10 has more available content, multiple services require Dolby Vision for HDR playback.
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 (around 100 dB), the quality of sound is very weak, especially when it comes to bass. The speakers sound unclear and muddy.
Con Dark scenes look shallow
Because of the really low native contrast ratio of 907:1, dark scenes look washed out if the TV is placed in a dark environment.
Con Not suitable for competitive gaming
While the TV's input lag of 19.7 ms is noticeably smaller than the overwhelming majority of TVs on the market, it still can not compete with rapid TN gaming monitors when it comes to fast and competitive gaming. The input lag of such panels can go all the way down to 3 ms.
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 Non-intuitive smart OS
Unlike other Sony TVs, the X720E has a custom, Linux based operating system which runs the Opera TV application store. OS is unintuitive and confusing to use.
Con Poor viewing angles
The picture quality on the X940E suffers from some degradation when viewing from an angle, as typical of a VA panel. The colors shift with even just a little deviation in the viewing angle, and the blacks become less apparent with it turning grey-ish.
Con Lacks support for Dolby Vision
The X940E can currently only play HDR10 content. It does not support Dolby Vision.
