TCL P607 55" (55P607) vs Sony X940E 75" (XBR75X940E)

At $650, it's hard to find a better deal for a 55-inch 4K TV that can also handle HDR content reasonably well.

Compared to its direct competitors, its picture quality is more or less similar to them. Although the HDR performance is just a tad below them, it's still great, especially for the price.

It's also more versatile because it has better features for gaming - the input lag of ~15ms is among the lowest in 4K TVs on the market, and it has a motion blur of ~12ms that stacks up to more expensive options.

The screen size is large for the price when compared to TVs in this price bracket, such as the Sony X900E which costs ≥$250 more for the 49" model.

The P607 can play both HDR10 and Dolby Vision content.

The P607 runs on the Roku TV smart platform, touted for its simple, straightforward, and lag-free UI.

It’s easy for anyone to grasp how navigation works, thanks to its two-column design with the menu on the left and options on the right.

There’s also no noticeable lag during navigation or menu selection.

In a decently-lit environment, the P607's colors won't look dull thanks to the panel's high peak brightness levels and decent handling of reflections.

It's bright enough to fight off glare with peak brightness levels of ~500 nits for both SDR & HDR, and the intensity of reflections are also reduced by panel's semi-gloss finish.

The P607 has low input lag and barely noticeable motion blur, making for a responsive and fluid gameplay experience.

The input lag is barely noticeable at ~15ms for both SDR & HDR inputs, and the panel only requires ~12ms to fully change the pixels color, resulting in fast-moving objects not leaving any trails on the screen, eliminating virtually all motion blur.

The P607 is excellent at reproducing colors accurately out of the box.

Even without calibration, the colors are spot-on. They're very close to what the source signal demands, and any inaccuracies are generally considered imperceptible to most end users.

The overall average difference between the source signal and the panel's reproduction of the color is measured in Delta-E, where lower means better accuracy. The P607 has a Delta-E of below 2.0, and anything below 3.0 is generally considered accurate for most end users.

On top of its excellent picture quality, the P607 has everything essential to a great HDR experience: local dimming, wide color gamut, and fairly high peak brightness level.

Highlights will really stand out as the deep black levels are further improved with local dimming. It can make parts of the screen darker when the image calls for it, resulting in a fairly huge boost in picture quality as the black levels become deeper.

The wide color gamut enables the panel to reproduce the full range of colors required for true HDR playback. The screen can get sufficiently bright at a peak level of ~500 nits to light those colors up and make HDR details really pop.

The P607 has no ads on its main interface, although there can be ads in third-party applications. Third-party ads can't be blocked, but the tracking and personalisation can be limited through the TV's settings.

The P607 can upscale 480p, 720p, and 1080p content to 4K very well. The upscaled content has almost no artifacts, and the crisp details are preserved.

The P607 looks true-to-life with lots of details.

There’s a great depth to pictures and you’ll be able to see everything stand out. Dark scenes are great and you won't miss out on any details, even in shadows.

The panel has a contrast ratio of about 6500:1, which means it can produce blacks that are 6500 times darker than the brightest white. This can be pushed even further to over 7000 with local dimming.

The colors are lifelike and accurate even without any calibration by the user. They will look really vibrant even in bright scenes because of the panel’s high peak brightness levels of ~500 nits for SDR & ~550 nits for HDR.

Even in a decently-lit environment, the P607’s picture quality can still hold up - the panel is great at handling reflections and it can get bright enough to fight off glare.

The X940E's performance can be considered on par with the OLEDs in this price range. It has everything necessary for true HDR: high native contrast (4941:1, can go up to 11634:1 with local dimming enabled), wide color gamut, great black levels and uniformity. Beyond all that, its panel is one of the best in the market — even in a bright room, this TV can still really shine because of how bright it can get.

Local dimming is the TV's ability to dim areas of the screen for deeper black levels and better contrast — they are separated into different dimming zones, where each zone can be individually dimmed as needed. The local dimming on the X940E is the best in LED TVs of 2017 — it is capable of doubling the contrast ratios from 4941:1 to 11634:1. The only other LED TV with this capability is the VIZIO P65-E1, but its contrast with local dimming enabled is lower than the X940E's (at ~9.3k:1).

The user interface of modern smart TVs can include some advertisements similar to those on the internet or in a mobile app. The X940E does not include any, and it also has a feature for limiting ads in third-party applications.

The X940E can handle dark scenes very well thanks to its high native contrast levels, which clocks in at 4941:1 native, and it can go up to 11634:1 with local dimming enabled. This, along with excellent black levels and uniformity, gives the TV the ability to achieve great representations of dark scenes beyond most expectations.

The black levels of a TV affects the viewer’s perception of other colors next to it. If the black levels are not deep enough and doesn’t remain uniform across the screen, the overall picture quality will look “flat” without much depth. The X940E handles this extremely well with one of the lowest deviation (<0.6%) ever in a non-OLED panel. This is measured across the entire screen from what a pure black screen should be, giving it significant gains in its native contrast levels thereby increasing the picture quality by a ton.

The X940E has a practical peak brightness of ~1,100nits for both SDR and HDR content — this is by far the second brightest ever in a VA panel, only bested by the X930E. It can sustain this level of brightness when playing content and it will not have any issues with fighting light in bright environments thanks to its virtually reflection-less panel.

The X940E runs on Android TV — normal Android apps from the Google Play Store (or other app stores) will work on it.

Unlike the OLED panels in this price range, the X940E has a VA panel and thus it does not suffer from image retention issues.

The X940E shines in dark environments — it is great at reproducing dark scenes, making it suitable for enjoying media in a cinema-like setting. It performs extremely well in movies with many black highlights/scenes where this is immediately noticeable even to undiscerning viewers (e.g. Interstellar).

The X940E's panel has a glossy finish, unlike the X930E which has a semi-gloss finish. This, along with its ability to get very bright, means that this TV is excellent at handling reflections — even in a bright room, the picture quality will remain more or less the same.

The color gamut of a TV refers to the range of colors the display can reproduce — the wider the color gamut, the more colors it can display, and the better the overall picture quality will be. This is extremely important for HDR content because it requires a much wider color gamut than SDR content. The X940E has no issues with accurately reproducing the colors necessary for true HDR because its color gamut is one of the widest and only bested by some OLEDs.

The X940E is the best LED TV of 2017, outperforming its competitors in nearly every aspect. Its picture quality is top-notch for any kind of content and it can handle all sorts of use cases really well.
