Pro Excellent at handling glare
The MU9000's panel has a glossy finish that reduces reflections significantly. This makes it excellent at fighting glare, along with its adequate brightness levels of ~400 nits for SDR & ~450 nits for HDR.
Pro Capable of smooth 24p content playback
The MU9000 is great at dealing with 24p content, such as Blu-rays or media sourced from a cable or satellite box. It can detect and eliminate the judder effect present in these content, where images displayed can appear jittery.
Pro Inputs are very accessible
The MU9000 comes with a OneConnect box which moves all the hard-to-access rear inputs away from the TV. Thanks to this, you’ll always have full access to all inputs and outputs of the TV even if it’s wall-mounted. The OneConnect box can also be used as a USB charging hub.
Pro Intuitive user interface
The MU9000 runs on the Tizen smart platform, known for its simplicity and intuitiveness.
It’s easy to navigate and access all the functions of features of the TV - the whole menu of the Tizen OS is organized around a menu known as the “Smart Hub” which contains everything: apps, settings, input switching, etc.
It also has a section for quick access to frequently used items.
Pro Great at upscaling low-res content
The MU9000 can upscale 480p, 720p, and 1080p content to 4K quite well. The upscaled content has almost no noticeable artifacts, and all the details are preserved.
Pro Suitable for gaming and watching sports
The MU9000 is pretty versatile. On top of its great picture quality, it has features that makes it perform quite well for gaming and sports.
It offers a responsive and fluid gaming experience - players will have no issues keeping their actions in sync with what’s on the display, and fast-moving objects won’t leave any trails on the screen. That is thanks to the low input lag of ~25ms and the panel’s quick response time of ~15ms, which results in virtually no motion blur.
It’s also great for watching sports because of the virtually non-existent motion blur that makes fast-moving objects, like football, look smooth. The panel is also pretty uniform - it has also has no issues with displaying large, same-color objects on screen, like football fields.
Pro Remote has a voice command feature
The MU9000's remote has a voice command feature that can perform actions as you physically would with the remote, and it can even be used to adjust settings directly.
Pro Good for HDR content
On top of its great picture quality, the MU9000 has a high HDR peak brightness level and wide color gamut that makes it good for HDR.
Shadows look pretty good with nice details, and highlights are quite vibrant thanks to the peak brightness level of ~450 nits.
The panel can reproduce the wide range of colors required for true HDR playback because of its wide color gamut, which covers ~60% of the standard colors required for HDR according to the Rec. 2020 color space. This is considered decent enough for reproducing HDR details, and it can display these colors accurately at different brightness levels.
It’s worth noting that while the MU9000 has local dimming that’s supposed to make HDR better, the local dimming is crap and doesn’t do much - it increases the contrast ratio by a meager amount and does nothing else.
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 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 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 Ads-free main interface
The main interface of the smart OS does not feature advertisements or sponsored content.
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 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 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.
Con Not suitable for group watching
The MU9000 has a narrow viewing angle that makes it unsuitable for watching with groups.
Audience 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 ≥20° away from the screen's center - the colors will start looking dull and blacks will look like greys.
Con Lacks support for Dolby Vision
The MU9000 currently only supports the HDR10 format for HDR content.
Con Interface has ads
There are ads that can't be removed on the MU9000's interface.
Con Mediocre sound quality
The sound quality of MU9000's built-in speakers is mediocre. It sounds quite bassy and the clarity is reduced at higher volumes - you might have a hard time following dialogues at higher volumes because of this. There’s also distortion at higher volumes.
Con Not really high value for money
The MU9000 is a great TV, but the retail price can be off-putting for some because the picture quality and features it offers are present in other similarly-priced models, e.g. the Sony X900E. This TV can be really worth it when on sale, or if Samsung offers better after-sales service in your region.
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 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 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 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 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 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.
