Ranked in these QuestionsQuestion Ranking
Pro Excellent value for money
The S405 strikes a nice balance between picture quality, screen size, and input lag, all for an affordable price of below $500. It's a great choice for watching and gaming casually without breaking the bank.
Compared to its direct competitors, it offers decent picture quality that is a tad below them, bigger screen size, and lower input lag.
Content looks decent enough for most casual viewers - the black levels are sufficiently deep, colors are vivid, and it gets bright enough for most types of content in a dark room.
The size difference is pretty huge as options with similar size of 49", or even smaller, cost fairly more than the S405.
Its low input lag of ~15ms contributes to a more responsive gaming experience. It's barely noticeable, and it’s also one of the lowest among 4K TVs, which is an impressive feat in this price bracket.
Pro Works well as a computer monitor
The S405 works well as a computer monitor thanks to its low input lag, barely noticeable motion blur, and full 4:4:4 color support. The 43" model can even be used up close due to its small minimal viewing distance.
The low input lag and low motion blur of ~15ms makes it highly responsive to input and gives it the ability to handle dynamic content well.
It also has full 4:4:4 color support, so text or shapes with hard edges on the screen won't be blurry.
Pro Decent for watching sports
The S405 is a good pick for watching sports thanks to its low motion blur and reasonably consistent color uniformity.
Fast-moving objects, like footballs, won't leave any visible trails on the screen due to the low motion blur of ~15ms. While there are slight uniformity inconsistencies in the edges of the panel when displaying large, uniform objects on the screen, like football fields, the issues generally go unnoticed by most.
Pro Intuitive and smooth user interface
The S405 runs on the Roku TV smart platform, touted for its simple, straightforward, and lag-free UI.
It’s easy for anyone to grasp how navigation works, thanks to its two-column design with the menu on the left and options on the right.
There’s also no noticeable lag during navigation or menu selection.
Pro Excellent for gaming
The S405 is excellent for gaming - the overall experience will be very responsive and fluid, thanks to the really low input lag and barely noticeable motion blur.
It has an input lag of ~15ms that makes the TV highly responsive to user input - gamers will have no issues keeping their actions in sync with what's on the display. The panel can fully change its pixels color in under 15ms, resulting in fast-moving objects not leaving any trails on the screen, eliminating virtually all motion blur.
It's also suitable for HDR gaming because there is no increased input lag for HDR, and it has full 4K support @ 60 FPS, which makes it suitable for all new 4K games.
Pro Main interface has no ads
The S405 has no ads on its main interface, although there can be ads in third-party applications. Third-party ads can't be blocked, but the tracking and personalization can be limited through the TV's settings.
Pro Colors are accurate even without calibration
The S405 is excellent at reproducing colors accurately out of the box.
Even without calibration, the colors are spot-on - they're very close to what the source signal demands and any inaccuracies are generally considered imperceptible to most end users.
The overall average difference between the source signal and the panel's reproduction of the color is measured in Delta-E, where lower means better accuracy. The S405 has a Delta-E of below 2.0, and anything below 3.0 is generally considered accurate for most end users.
Pro Decent picture quality
The S405 looks decent with adequately deep black levels, above-average color accuracy, and sufficient peak brightness levels for most content.
It’s especially great at reproducing dark scenes thanks to the panel’s contrast ratio of about 4000:1, which means blacks can get really dark at about 4000 times darker than the brightest white it can produce.
Colors are spot-on even without calibration, and the panel can get bright enough with a peak brightness level of ~200 nits to make them pop in dark environments.
The best viewing experience will be in a dark environment where the panel won’t have to compete with light. The S405’s screen can’t really get bright enough to perform as well in bright environments.
Pro Well-balanced side inputs
Even when the S405 is mounted on a wall, you'll still have access to all essential inputs and outputs which are situated on the side of the unit.
Pro Highly versatile
The S405 is versatile enough to be used as a general-purpose display.
The picture quality is decent for movies and TV shows, and it checks all the boxes that make a TV suitable for gaming, sports, and as a computer monitor: low input lag, low motion blur, good screen uniformity, and full 4:4:4 color support.
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.
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 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 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 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 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 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 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 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.
Good color uniformity is another parameter that really makes a difference when watching sports. It allows the TV to display beautiful and uniform sports fields and pitches, without any unwanted artifacts. 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.
Con Can't fight glare very well
The S405 can deal with low amounts of light, such as sunlight through curtains, but it won't be able to deal with a significantly bright light.
Apart from being unable to get bright enough, its reflection handling is only average. The panel has a semi-gloss finish which helps in reducing reflections a little, but its peak brightness level of ~200 nits is not enough for fighting glare.
Con HDR support is basic
The S405 can't reproduce HDR pictures very well because it lacks various important features.
HDR won't look much different from SDR due to the lack of wide color gamut and low peak brightness. It can't reproduce the full range of colors necessary for HDR, and the brightness level of only ~200 nits is barely enough for HDR content to stand out.
The black levels are also insufficient for highlights to stand out, and it won't be as dynamic as one would expect for HDR due to the lack of local dimming.
Con Poor sound quality
The speakers on the S405 are too bassy, so distortion becomes a huge problem at high volumes. A relatively cheap speaker system or a soundbar will make a huge difference in sound quality.
Con Remote lacks functionality
The S405 has a basic remote that is only capable of navigation, playback control, and volume control. It doesn't have fancy stuff like voice command found in remotes of other TVs.
Con Lacks support for Dolby Vision
The S405 only supports the HDR10 format for HDR content.
Con Not suitable for group watching
The S405 has a narrow viewing angle that makes it unsuitable for watching with groups.
People sitting away from the center of the screen will not experience the same picture as those sitting in the center because the picture quality starts to deteriorate significantly when viewing from just ≥30° away from the screen's center.
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 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.
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 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 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 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 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 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.
