Pro Good for gaming
The UK6300 offers a responsive and lag-free gaming experience. It has low input lag and a good refresh rate.
The TV has one of the lowest input lags in the market – approximately 11.5 ms. The “Game” and “_PC_” picture modes help achieve this. Moreover, the latency increase while gaming in 4K or HDR is extremely tiny and doesn't go past 1 ms.
The TV is great for high-end console gaming. It has a 60Hz native refresh rate and you can game in 4k60Hz if you enable the “HDMI Ultra HD Deep Color” setting.
Pro Good for dynamic content
This TV is a great option for fast-paced content such as sports and video games due to the quick response time. This makes sure the content doesn't appear blurred out due to fast movement on-screen. A full pixel color transition on the TV's panel takes 15 milliseconds.
Pro Strong smart TV platform
The UK6300 runs on LG’s WebOS. The interface is functional and easy to navigate.
LG Content Store has a wide range of apps, including popular media streaming services such as YouTube, Amazon, Netflix, etc., and many other third-party apps, which are all kept up-to-date.
Pro Good viewing angle
The UK6300 is a good TV for rooms with wide seating because it offers a better viewing angle than other TVs at this price-point. The blacks are consistent at any viewpoint, and the color and brightness shifts aren’t too bad – they become noticeable at moderate angles. Colors shift at 22 degrees, whereas brightness shifts at 27 degrees.
Pro Makes an excellent computer monitor

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.

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 Lower color resolution
The picture is less detailed and lower in quality due to the RGBW pixel structure, which means that only 75% of the total panel's pixels can produce colors.
Con Struggles with darkness
The UK6300 can’t reproduce deep blacks and dark room viewing is not too great. This is due to the mediocre contrast ratio, no black uniformity and the lack of local dimming.
The blacks tend to look grey due to the brightness difference between white and black - the native contrast ratio is only 1096:1. Compared to other TVs this is a very low value.
Moreover, the TV has less than ideal black uniformity and no local dimming. The standard deviation for black uniformity is approximately 3%, which, when compared to the much lower percentages of competing TVs, is very disappointing.
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.
