When it matters: Different technologies have different performance and are suited to different uses
Good value: IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle. OLED maintains good color accuracy at an angle without any of the other issues seen with IPS and VA, as they keep good brightness and contrast at an angle.
:
IPS
Resolution : 4k

The Sony X750F is a decent 4k IPS TV. It has decent picture quality which you can also view from an angle without loss of quality, but unfortunately, this comes at the expense of poor blacks in dark rooms. The TV has great out of the box color accuracy and good gray uniformity so slow panning landscape shots will look good. Brightness is decent, but only enough for an average lit room. Movie and HDR performance are mediocre as the TV has low native contrast ratio, and lacks a wide color gamut to display rich, saturated colors and to make highlights pop.

Design

Score components: Subjectively assigned
Sony X750F Design Picture
Curved : No

The design of the Sony X750F resembles very much the design of the Sony X830F. The stand supports the TV well and has a plain and sturdy design that allows for a soundbar to be placed in front. The stand also serves as the TVs cable management path as it routes the cables through its rear legs. The back of the TV is plain, and although the X750F is a little thick, it will not protrude much if wall mounted. The build quality is good and at par with most Sonys.

Stand
Sony X750F Stand Picture

The stand of the X750F is a blend. It is fully plastic but the front part of each leg has a metallic tint whereas the rear part is black and has a channel to route cables. Unlike the X830F, you can not reverse the legs so that the front becomes back, nor can you switch the left leg with the right one. The stand supports the TV well but does not prevent wobbling. It is almost as wide as the TV itself so you will need a wide table.

Footprint of the 55" TV stand: 39.8" x 13.6"

Back
Sony X750F Back Picture
Wall Mount : VESA 200x200

The back is plastic and resembles a lot the back of the X830F but it has a little bulkier feel. Cable management is well thought of as cables can be routed through the legs of the stand. However, if you wall-mount the TV, you might have some difficulty accessing some of the ports.

Borders
Sony X750F Borders Picture
Borders : 0.61" (1.6 cm)

The borders of the Sony X750F are plastic and have an average thickness.

Thickness
Sony X750F Thickness Picture
Max Thickness : 3.11" (7.9 cm)

The Sony X750F is thicker than most 2018 TVs we've tested. It is very similar to the X830F, but thicker than the X850F and the X900F. However, this should not be an issue if wall mounted.

Temperature

The Sony KD55X750F runs fairly cool and thus the operating temperature should not be an issue.

7.5 Build Quality
Sony X750F Build quality picture

The build quality of the X750F is good. There are no gaps or loose ends and you should have no issue with it.

7.1

Picture Quality

The picture quality of the Sony X750F is decent. The contrast ratio is low, and the TV cannot display deep uniform blacks, which is noticeable when you are in a dark room. It can get reasonably bright, but not bright enough to overcome the glare of a bright room. The color accuracy out of the box is remarkable, and most people will not need to calibrate to correct any color inaccuracies. The viewing angles are decent, and you can watch the TV from small angles without sacrificing picture quality. Gray uniformity is good as is reflection handling.

5.9 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.
When it matters: Always, but especially when watching dark scenes.

N/A

The native contrast ratio is disappointing. This is expected from an IPS panel and the result is very similar to the higher end model X850F.

Update 09/21/2018: We have heard reports that the 65" model has a VA panel. We haven't confirmed this, but if so we expect it to have a higher contrast ratio (3000:1 or more) but poor viewing angles.

0 Local Dimming
What it is: The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters: Dark scenes viewed in a dark room.
Score components: Subjectively assigned

No
Backlight
What it is: Configuration of the lights of the backlight.
When it matters: Effectiveness of the local dimming.
Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.

The overall gray uniformity of the X750F is good. Very similar to the other Sony models from the last two years. The results of the 50% gray is a little worse than the 5% gray. You can notice the sides and the corners of the screen that are darker than the center. The good news is that there is not much dirty screen effect visible, and thus sports will look good.

Decent viewing angles. The image remains fairly constant as you view it from a fairly wide angle. The result is at par with other IPS sony models like the X800E and X850F but is slightly worse than last year's X720E.

Update 09/21/2018: We have heard reports that the 65" model has a VA panel. We haven't confirmed this, but if so we expect it to have a higher contrast ratio (3000:1 or more) but poor viewing angles.

The Sony KD55X750F has good reflection handling, better than last year's X720E and X800E. The TV is capable of diffusing well the indirect reflections, or ambient light, but does not do as well with the reflections of light sources directly opposite the screen.

Excellent out of the box color accuracy of the Sony X750F. This accuracy is very close to that of the X900F and much better than the X830F or the X850F. Most people will be satisfied with this TV out of the box and the TV won't benefit much from a professional calibration.

'Custom' is the most accurate picture mode out of the box with white balance dE and Color dE at very low levels, and most people will not notice any inaccuracies. Gamma is spot on our target of 2.2. The gamma curve is followed quite accurately until the higher input levels where the TV is slightly brighter than our stimulus.

9.0 Post Calibration

Excellent results after calibration for the X750F. The gray inaccuracies almost disappeared although the color inaccuracies were not improved.

Overall, the calibration was able to improve the accuracy only slightly, as the TV was already very accurate out of the box. Also, the color dE could not be diminished because Sony TVs do not have a color management system. Unfortunately, the final result is not as accurate as the X850E or the X830F.

Sony X750F EOTF

The HDR color gamut of the X750F is decent. The Rec 2020 coverage, however, is limited and does not meet our threshold for a wide color gamut TV. In very colorful scenes the TV's limited color gamut will be noticeable.

The HDR EOTF in 'Custom' picture mode with Contrast at 90 follows the target PQ quite well. The results in the 'Game' picture mode and in 'PC' picture mode are almost identical.
If you raise contrast to 'max' you can get a slightly brighter image but with a more abrupt clipping of the brighter highlights, as shown in this plot.

If you find HDR content too dark you can raise the Contrast to 'max', Gamma to max and Adv. contrast enhancer to 'High' to raise the EOTF. This will have a result of almost everything being brighter, as shown in this plot, at the expense of earlier rolling off.

The gradient of the Sony X750F is great. Gray is excellent as with most Sonys, but there is some banding in the other colors.

Even if you do notice a case of major banding that bothers you, you can use Random noise reduction for analog (film) or Digital noise reduction for older digital content to reduce it, but this can result in a loss of some fine details.

7.5

Motion

Good motion handling for this Sony X750F. It has a fast response time that leaves a small blur trail behind the image that makes it look smooth. If you wish to make it more clear at the expense of brightness you have the option of introducing flicker with the aid of the black frame insertion feature. This TV will also keep fans of the soap opera effect happy with its motion interpolation feature. Finally, it does not support any variable refresh rate implementation to remove screen tearing from graphically demanding games and its 24p judder removal feature implementation is sub-par.

The Sony X750F has a 60Hz panel which can interpolate lower frame rate content up to 60p. To enable interpolation, set Motionflow to 'Custom' and increase the 'Smoothness' slider to your liking. Any motion interpolation introduces artifacts, so unless you really like the soap opera effect, use it with caution.

The TV can automatically remove 24p judder from older movies. Unfortunately, it cannot remove the 24p judder if it is found within a 60p or 60i signal or within the Native Apps. If judder is really an issue you can set Motionfllow to 'Smooth' and Cinemotion to 'Auto'. This will help remove judder, but it will add some motion interpolation

0 Variable Refresh Rate

To properly display chroma 4:4:4, the Picture mode must be set to 'Graphics' or 'Game'. When the TV is sent a 1080p signal in 'Graphics' mode, the upscaling changes to the jagged nearest-neighbor upscaling type, seen here on the X900E, that some people prefer for PC use.

Only HDMI ports 2 and 3 support HDMI full bandwidth, so 4k @ 60Hz @ 4:4:4 or 4:2:2 is only possible on these two ports and only when Enhanced format is enabled on the TV.

Sharpness 50 (default) means no added sharpness in Graphics mode.

Sound Quality

What it is: How well and accurately the audio is reproduced.
When it matters: When a good and accurate sound reproduction is needed.
Score components:

The sound of the Sony X750F is mediocre-at-best. This TV gets pretty loud, and produces clear and intelligible dialog. However, it doesn't produce any sub-bass and therefore lacks thump and punch to its bass. For a better sound, dedicated speakers or soundbars are recommended.

5.9 Frequency Response
What it is: How accurately the sound level of each frequency is being produced.
When it matters: For a balanced and neutral sound.
Sony X750F Frequency Response
Low-Frequency Extension
What it is: The lowest frequency at which the frequency response reaches -3dB of the target response.
When it matters: Movies, Gaming. Shows how extended the bass is.
Good value: < 60Hz
Noticeable difference: 10Hz
:
126.99 Hz
Std. Dev. @ 70
What it is: The amount of deviation (weighted standard deviation) in frequency response measured at 70dB SPL, as compared to a target response that would sound perfectly balanced to most people.
When it matters: Shows the TV's frequency response at quiet listening levels
Good value: < 4 dB
Noticeable difference: 0.5 dB
:
4.89 dB
Std. Dev. @ 80
What it is: The amount of deviation (weighted standard deviation) in frequency response measured at 80dB SPL, as compared to a target response that would sound perfectly balanced to most people.
When it matters: Shows the TV's frequency response at moderate listening levels
Good value: < 4 dB
Noticeable difference: 0.5 dB
:
5.34 dB
Std. Dev. @ Max
What it is: The amount of deviation (weighted standard deviation) in frequency response measured with the TV at maximum volume, as compared to a target response that would sound perfectly balanced to most people.
When it matters: Shows the TV's frequency response at under maximum load
Good value: < 4 dB
Noticeable difference: 2 dB
:
6.76 dB
Max
What it is: Maximum volume reached by the TV at their optimum viewing distance (size dependent)
When it matters: For listening to loud audio.
Good value: > 88 dB
Noticeable difference: 2 dB
:
91.2 dB SPL
Dynamic Range Compression
What it is: The amount of difference between the TVs frequency response performance at 70dB SPL and Max dB SPL. Too much compression will result in pumping in the sound.
When it matters: When an accurate and free-of-pumping performance is required at higher volumes
Good value: < 3dB
Noticeable difference: 0.5
:
3.52 dB

The frequency response of the X750F is mediocre-at-best. The LFE (low-frequency extension) of 127Hz indicates a bass that produces no thump, rumble, or punch, which is common to bass-heavy film scores and video game sound effects. However, the bump around 200Hz compensates for this lack somewhat, by making the sound a bit fuller. The response above 200Hz is very good and even, which is important for producing clear and intelligible dialog. Additionally, this TV gets pretty loud, without producing too much compression and pumping artifacts.

4.4 Distortion
What it is: Deformation of an output signal compared to its input, usually clipping, harmonic distortion, or inter-modulation distortion caused by non-linear behavior of the sound system.
When it matters: When a clean, pure and transparent reproduction is desired.
Score components:
Sony X750F Total Harmonic Distortion
Weighted THD @ 80
What it is: The overall amount of harmonic distortion measured at 80dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters: How pure the sound is at moderate listening levels.
Good value: < 0.100
Noticeable difference: 0.100
:
0.197
Weighted THD @ Max
What it is: The overall amount of harmonic distortion measured at the TV's maximum SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters: How pure the sound is at moderate listening levels.
Good value: < 0.100
Noticeable difference: 0.100
:

IMD @ 80
What it is: The average amount of inter-modulation distortion produced by the TV under maximum load. The percentage shown here is the average result of 3 separate test signals/standards: SMPTE, DIN, & CCIF
When it matters: When a clean and free of aliasing reproduction is desired
Good value: < 5%
Noticeable difference: 2
:
144.51 %
IMD @ Max
What it is: The average amount of inter-modulation distortion produced by the TV under maximum load. The percentage shown here is the average result of 3 separate test signals/standards: SMPTE, DIN, & CCIF
When it matters: When a clean and free of aliasing reproduction is desired
Good value: < 5%
Noticeable difference: 2
:
75.95 %

The distortion performance of the X750F is sub-par. The overall amount of THD produced at 80dB SPL is within decent limits, however like most other Sony TVs, there is a big jump in THD under maximum load. But this won't be very noticeable in real-life situations.

Sony X750F Smart TV Picture
Smart OS : Android TV
Version : 7.0

The Sony X750F uses the same Android TV found in the other Sony TVs models we have reviewed this year. Just like the X850F or the X830F, it has numerous built-in apps and you can download many more from the Google Play Store. The interface is decent, but it can be slightly laggy sometimes and the animations can be choppy. You can quickly access Google Assistant through the remote and you can search for apps or content by voice, but you cannot change the TV settings.

7.0 Interface

The interface of the X750F is decent. The TV runs the Android TV interface which is intuitive but crowded and some might not find pleasant to use. The home screen is long and it can take a lot of scrolling before you reach to the menu item you want. Just like the X830F, the interface has an inconsistent behavior where sometimes it is fast, and other times it lags and animations become choppy. The home menu does not respond quickly and this is unfortunate considering its use frequency. The good news is that there are many buttons on the remote that allow you to navigate quickly where you want, and the voice control feature that can also help.

10 Ad-Free

The Sony X750F includes the same remote as the X850F. It has more buttons than most remotes and is quite large, but with good usability. Buttons are easy to find and it doesn't take long to access most basic functions of the TV.

The included voice button works well to access Google Assistant, but the remote must be connected to the TV via Bluetooth for this to work. Google Assistant can perform most basic actions on the TV, such as changing inputs or opening certain apps. More advanced functions such as changing picture settings do not work.

You can download from Google Play and iOS, Sony's 'Video & TV SideView: Remote'. This will allow video files from a smartphone to be cast on the X750. The app also allows your smartphone to control other Sony devices including Blu-ray players or home theater systems. Unfortunately, the app does not allow you to input text in any of the TV apps, even though you can input text in the android text boxes.

Differences between Sizes and Variants

We tested the 55" (KD55X750F). For the most part, we expect our review to be valid for the 65" model (KD65X750F), and the 43" and 49" models currently available in Canada and the UK. The UK variant of the TV is also known as the Sony XF75.

The 43" and 49" models have an external power adapter (brick), the 55" and 65" have it built-in.

If someone comes across a different type of panel or if their Sony X750F doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

Compared to other TVs

Top left: Vizio E Series 2018 (E65-F0). Bottom left: Samsung NU7100 (UN55NU7100). Middle: Sony X750F (KD55X750F). Top right: Sony X830F (XBR60X830F). Bottom right: LG UK7700 (55UK7700PUD).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Sony X750F is a decent TV that performs better for casual TV watching.

Samsung NU7100
40" 43" 50" 55" 58" 65" 75"

If you have a room with wide seating arrangement, the Sony X750F is a better choice than the Samsung NU7100 as it has better viewing angles. But if you have a dark room with seating directly right in-front, then the Samsung NU7100 is better. The Samsung has deeper blacks, and you will enjoy watching movies more. The Samsung also has lower input lag, and this is great if you play video games. On the other hand, the Sony can remove 24p judder from older content.

TCL R617
55" 65"

The TCL R617 is much better than the Sony X750F. The TCL has better blacks and better HDR performance due to the high native contrast ratio and local dimming support. It also has better brightness and a wide color gamut, and in HDR, it can make highlights pop. It has lower input lag which is important if you play games or use the TV as a PC monitor. On the other hand, the Sony has better viewing angles and is more suitable for wide seating arrangements.

LG UK7700
55" 65"

The LG UK7700 is better than the Sony X750F. The LG supports local dimming to improve quality of blacks and also has lower input lag, which is great if you play video games or use it as a PC monitor. The LG can handle reflections better and you can easily place it in a bright room like a kitchen without issues. On the other hand, the Sony X750F has better black frame insertion that can clear the image blur better.

Vizio M Series 2018
55" 65" 70"

The Vizio M Series 2018 is much better than the Sony X750F. The Vizio can get brighter, has better blacks due to better contrast ratio and local dimming support and offers a better movie experience in a dark room. The Vizio also has a lower input lag which you will appreciate if you play video games or use the TV as a PC monitor. On the other hand, the Sony X750F has better viewing angles for wide seating arrangements and a motion interpolation feature to please the soap opera effect fans. 

Conclusion

Amazon.com

7.3Mixed Usage
What it is: General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
This is a decent TV for mixed usage. Its viewing angles allow you to watch it from the side so it is a TV that you can place in a wide room. It does not have deep blacks so it is not suitable for a dark room but rather for an average lit room where lights are not directly facing the screen. It will perform better when watching sports or TV shows or playing a casual game.
6.1Movies
What it is: Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
This is a mediocre TV for watching movies in a dark room. Blacks look gray as the TV's contrast ratio is disappointing and the 24p judder removal feature will not work well from external players that send 60p or 60i signals. Motion handling is decent and fast motion will look smooth, but the limited color gamut does not allow the TV to produce rich, saturated colors to improve picture quality.
7.8TV Shows
What it is: TV Shows in a bright living room. The TV will be used in to watch TV shows, in a bright room during the day, from multiple viewing positions at different angles. The content watched has an average quality: cable, streaming, SD channels, etc.
Score components:
This is a good TV for watching TV shows. You can easily place it in an average lit room and you do not have to watch from straight in front to enjoy the same picture quality. It has a motion interpolation feature for the fans of the soap opera effect. This TV is a good choice if you will spend most of your time watching TV shows.
7.6Sports
What it is: Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
The Sony X750F is a good TV for watching sports. You can place it in a large fairly bright room and you can invite your friends to watch your favorite team play. It has wide viewing angles, good reflection handling and a fast response time that displays fast motion smoothly. Gray uniformity is good so you will not notice any dirty screen effect and the cable signal is upscaled well so that you enjoy every little detail of the pitch.
7.8Video Games
What it is: Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
The Sony X750F performs well in video games. It has a low input lag and feels very responsive to your inputs. Its response time is fast, so fast action scenes look smooth. Unfortunately, if you play in a dark room, blacks will look grayish due to the sub-par contrast ratio. The TV does not support any of the more advanced gaming features like VRR, but this will not be an issue if you are a casual gamer.
6.0HDR Movies
What it is: HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Score components:
This is a mediocre TV for watching HDR Movies. The contrast ratio is low, and blacks look gray in a dark room where HDR is meant to be watched. The brightness level is not enough, and the limited color gamut is not allowing you to enjoy a rich and saturated image that depicts the directors intent. If HDR movies are what you are looking for, this TV should not be at the top of your list.
7.1HDR Gaming
What it is: HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
The HDR gaming performance of this TV is decent. This is mainly due to the low input lag the TV has on 4k @ 60Hz + HDR signal, and the fast response time. Unfortunately, the contrast ratio is low and the color gamut is limited so HDR performance is not good and the picture quality is not what the game director intended.
8.0PC Monitor
What it is: PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
This is a good TV for use as a PC monitor. The viewing angles are decent and thus you will not have any uniformity issues if you sit close. The response time is good so only a small trail will follow your mouse movements and the TV will feel very responsive due to the low input lag. Reflections are also good and the TV is capable of displaying clear and crisp text.
