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 Somewhat narrow viewing angles
Because of the display technology used, pictures will only look best in a narrow viewing angle as it significantly loses color accuracy and brightness at a wider viewing angle.
Con Troublesome to fit on some TV tables
The TV stand's large size and cumbersome design might not make it suitable for some TV tables.
Con Some harmonic distortion
Harmonic distortion is even as the volume increases, but significant distortion is present in the low-mids.
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 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.
