Sony X720E 43" (KD43X720E) vs TCL S517 65" (65S517)

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.

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.

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.

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.

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.

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.

The main interface of the smart OS does not feature advertisements or sponsored 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.

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.

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.

In terms of picture quality, the S517 is comparable to high-end TVs. It displays remarkably deep blacks due to its great contrast and reproduces details in color very well due to its good color gradient.

The 6000:1 native contrast ratio allows the TV to reproduce dark scenes particularly well. It is easily one of the best in this price range – it’s often compared to high-end counterparts.

The S517 has superb black uniformity and contrast that create pleasant, deep blacks. They are much better than those of the similarly-priced competitors. The maximum deviation sits at around 1.02% .

The TV is good at capturing small differences in color such as skin tones, green colors in nature, details in shadows, etc. This is because of the color gradient, which is on par with other options of the same price. There is almost no banding and the standard deviation of color doesn't go past 0,11%.

The S517 is a much better fit for HDR content and HDR gaming than its competitors due to the wide color gamut, decent color depth, and high contrast.

The TV can display a lot more colors than its similarly-priced counterparts. The coverage of the Digital Cinema P3 color space is very good - 90%.

The color depth is on par with competing options. The S517 has 10-bit color depth, which means that it can display approximately 1.07 billion colors in total. This is important for HDR content because HDR media takes advantage of 10-bit.

The S517 can display deep blacks in the HDR mode because of its high native contrast ratio of 6000:1, which is easily one of the best in the given price range.

The TV can also play all HDR content because it supports both standard formats of HDR - HDR10 and Dolby Vision. They enhance the viewing experience by editing the metadata, that is, the extra information that tells the TV how to display HDR. The formats differ in the way they deal with it, however - Dolby Vision edits the picture on a per scene basis, whereas HDR10 edits everything at the start of the video.

The TCL S517 is a decent option for pretty much everything, be it gaming, movies, sports, or HDR content. It has noteworthy picture quality, good all-around responsiveness, decent smart features, nice motion handling, and, most importantly, a great price.

The S517 does a reasonably good job with upscaling most content to 4K quality, be it 480p DVDs, HDTV or full HD Blu-rays.

The S517 offers the possibility to represent motion in videos smoother, also known as the "soap opera effect". This is done by making the TV take two frames and try to guess what would a frame in between of those look like, also known as motion interpolation. The frame rate can interpolate up to 60 frames per second.

All of the inputs are conveniently placed on the side of the S517, so you won't have to worry about leaving space between a wall and the TV.

The S517 offers a pleasant PC monitor experience not only due to the good responsiveness but also because of the video signal's compression.

The TV won't make text appear blurry while connected to a PC because the signal has no compression and transports color data and luminance fully. This is also known as chroma 4:4:4, and the “Computer” and “Game” modes display it properly at 60Hz.

The picture quality when you first open the TV up is quite decent. The only settings that could potentially require tweaking are grey inaccuracy and color inaccuracy. Either way, these are things that most people won't even notice.

The S517 is fit for all gamers because it offers a clear, lag-free experience. The TV is very responsive - it has struck a good balance between decent refresh rate, solid input lag, and good response time.

The TV is an ideal choice for console gaming in terms of its native refresh rate. It caps at 60Hz, which is perfect since most games won't benefit from anything higher than this.

The S517 is fast. An action shows on the screen in around 18 milliseconds, which can make the difference between managing to get a frag or waiting for a respawn. The time doesn't substantially increase when gaming in HDR or 4K either - it goes up to roughly 20.5 milliseconds. The only thing to remember is to keep "Game" mode enabled for the lowest possible input lag.

The TCL S517 also handles motion and fast-paced content quite well, it has a good response time. This makes sure you can keep up with fast-moving objects and a lot of action without it all appearing blurry. A full pixel color transition takes only 15.8 milliseconds.

The S517 comes with the Roku TV smart platform, which provides a comfortable interface and a big app selection.
