When comparing Samsung KU6300 vs Sony X720E (KD43X720E), the Slant community recommends Sony X720E (KD43X720E) for most people. In the question“What are the best 4K TVs to use as a computer monitor?” Sony X720E (KD43X720E) is ranked 2nd while Samsung KU6300 is ranked 3rd. The most important reason people chose Sony X720E (KD43X720E) is:
The Sony X720E makes an excellent computer monitor because of the TV’s short input lag, full 4:4:4 color support, and well-handled motion blur. The TV has enough processing power to keep its input lag and response time to a bare minimum. Its input lag is 19.7 ms, which ensures that it takes less than 1/50th of a second for the X720E to process an input signal generated by, let's say, a click of a button and display a corresponding image change. Furthermore, the X720E is a very responsive TV. It takes only 7.5 ms for its pixels to switch 80% to the next color; As a result, fast-moving objects don’t leave long trails on a screen which almost cancels out all the motion blur effects. The full 4:4:4 color support allows the X720E to process native computer-generated video input. As a result, the TV can display sharp and crisp image, without any detail loss. This is especially noticeable while viewing vector graphics such as text.
Ranked in these QuestionsQuestion Ranking
Pro Multiple resolutions and input modes
The set supports all the popular resolutions up to 4K at 60Hz refresh rate. The input lag for FullHD and 4K resolution, is surprisingly low even when receiving HDR signals, making this a great gaming monitor. In addition, chroma 4:4:4 sub-sampling rate is supported as well, meaning that the monitor will not show any artifacts or blurred out details when editing documents, pictures or browsing the web.
Pro Sharp, clear text in PC mode
Chroma 4:4:4 input is recognized in PC mode, so text will look sharp and clear.
Pro Picture specifications can live up to premium standards
Compared to other sets in this price range, this TV offers fantastic picture quality. Its high contrast ratio and black levels is comparable to TVs twice as expensive, making it great for movie watching. Color banding is not a problem as the panel offers great gradation. Brightness is even and enough for watching in bright conditions like sunlit rooms. Motion is handled well, thanks to the fast pixel response time and image processing.
Pro Multiple sizes versions exist
There are several sizes available to suit various needs and budgets.
Pro Good input access
Since the TV has all the inputs ordered neatly in one side, they can be reached easily even when the TV is mounted to a wall.
Pro Good for bright viewing conditions
The maximum brightness of the set is 420 nits, which is good for bright viewing conditions or for bright scenes on screen. Since the TV does not have proper HDR support, HDR content does not take advantage of this, however.
Pro Very dark blacks
A pure black screen measures just 0.024 cd/m², which means that when black colours or loading screens appear, they will truly look black (instead of the dark purplish glow which lower quality screens produce when displaying black colours). The deviation of black level across the TV is great as well - at half a percent the screen will appear extremely uniform with no bright spots.
This helps it achieve a very good contrast ratio of 4500:1.
Pro Good viewing angles
With 20° of viewing with no colour distortion, this is a good TV to use as a computer monitor. Because you'll be sitting close to it, the angle when looking at the far edges of the display are much more angled than when looking dead-on at the middle of the display. This means you'll notice much less colour shifting than other TVs with poorer viewing angles.

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.
Con Problems displaying HDR content
While HDR content is supported by the TV, it lacks the ability to properly display it. The KU6300 will display HDR content with less highlights and without the extra color data found in HDR compared to a standard signal. So although it can read and display HDR signals, you won’t be able to take full advantage of it.
Con Thick design
The bezel of the TV is made out of glossy plastic and it's 1.6 cm thick. The thickness of the TV itself is 6.2 cm, so it will stick out from the wall a bit.
Con Large footprint
The stand is made of plastic and t’s quite wide and reaches far towards the back, so this TV has a large footprint.
Con Noticeable distortion at high volumes
Harmonic distortion is minimal at low volumes, but the sound gets significant distortion at high volumes.
Con Good sound for its price
Low end frequency response cutoff is at a decent 90Hz, but there is a drop between 10-15 kHz at low volumes. Overall the response is average, but better than almost any budget TV.
Con There may be a need for an external sound system
The TV is loud, with a maximum volume of 89dB. However, since the sound distorts at high volumes, it is advisable buy an external sound system for larger rooms.
Con No support for signals above 60 Hz
The TV supports signals up to 4K resolution and 60Hz with HDR support, meaning that most formats are supported except for 1080p at 120Hz.
Con Color distortion and brightness loss at higher viewing angles
The monitor is best viewed directly as the viewing angle of the screen is really shallow and colors start to get distorted at 35 degrees. There is a noticeable brightness loss at 31 degrees.
Con Reflections are noticeable
The semi-glossy screen does not handle reflections well. Although direct reflections are seen clearly, ambient lightning reflections aren’t too noticeable.
Con Wide color gamut not supported
The TV has a 10-bit panel but it does not support a wide color gamut, so there won’t be a visible difference when it comes to HDR content.
Con No display port
Display port is a port used to deliver high amounts of data, and more favourable than HDMI for very high resolution high fps gaming.
Con Frame rates limited at 60Hz - poor for gaming
Gaming in 120Hz allows the TV to show more frames each second, delivering more up-to-date graphics than 60Hz TVs. 120Hz TVs will show refreshed screens twice as much, letting the gamer see their enemy up to a whole frame quicker. While not a con for the average gamer, high intensity FPS (first person shooter) gamers require extremely high refresh rates.
Con High response time means longer delays
Gamers require the fastest response possible so they aren't even a frame behind their opponents. The response time on this TV is 18.7. For comparison, computer monitors geared towards gaming often offer 5ms or lower response time. 16ms is commonly thrown around as the total delay before it can become noticeable. This 18.7ms delay plus mouse delay will be considerably over the 16ms threshold.
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.
