The Panasonic TX-75JX940 is a flagship 75-inch 4K LCD TV released by Panasonic. It features comprehensive HDR support, powerful video processing, and impressive gaming features. The design of the TV is sleek, with a slim screen frame and a centrally mounted stand. The build quality is premium, with a brushed metal desktop stand that provides stability. The TV utilizes an IPS panel illuminated by edge-mounted LEDs, which offers wider viewing angles but struggles with dark scenes.
However, Panasonic's Local Dimming Pro system aims to improve control over the shuttering mechanism of each LCD pixel. The TV is powered by Panasonic's latest HCX Pro AI processing engine and supports various HDR formats, including HDR10, HLG, Dolby Vision, HDR10+ Adaptive, and Dolby Vision IQ. It also offers image adjustment based on ambient light levels with its Filmmaker mode. The TV includes two HDMI ports that support 4K graphics at 120Hz frame rates, variable refresh rates, and automatic low latency mode switching. It also supports eARC for lossless Dolby Atmos audio. The TV's interface is powered by Panasonic's My Home Screen 6.0 smart system, which offers built-in voice control and a wide range of streaming services. It also includes support for Apple TV+.
In terms of picture quality, the TX-75JX940 excels in several areas. The HCX Pro AI video processing delivers images with subtle color detail, texture, and sharpness. The TV maintains a balance and subtlety in its use of light, shade, and color tones, resulting in immersive and convincing visuals. The native 4K resolution is well-utilized, with excellent sharpness, clarity, and vibrant colors. The TV can get very bright, making HDR content pop off the screen with intensity and punch. It also handles gaming well, with support for 4K/120Hz and VRR. However, the TV struggles with dark scenes due to its combination of an IPS panel and edge LED lighting. Dark scenes appear greyed over and flat, resulting in a loss of saturation, tonal accuracy, and shadow details.
The sound quality of the TV is impressive, with a big sound stage that matches the size of the 75-inch screen. The 2 x 15W speaker system delivers lots of subtle details and dynamic range, and Dolby Atmos soundtracks sound immersive with positional accuracy in the soundstage. Bass performance is also impressive, reaching deep levels without distortion. Overall, the TX-75JX940 has strengths in picture processing and sound quality, but its black level shortcomings detract from its overall performance. The price point of £1899 may also be a disadvantage compared to other options on the market.

A quick summary of the disadvantages of this model

This results in dark scenes appearing greyed over and flat, leading to a loss of saturation, tonal accuracy, and shadow details. The following are the potential downsides of purchasing this TV:
Limited control over light distribution: The edge lighting technique used in the TV makes it more difficult to control where the light goes, impacting the accuracy of dark scenes.
Constant greyness: Despite the Adaptive Backlight Control option improving things to some extent, the greyness remains a constant issue, affecting the overall visual experience.
Backlight fluctuations: The TV suffers from distracting backlight fluctuations, which can be noticeable during dark scenes and may detract from the viewing experience.
Price point: The price of £1899 may be a disadvantage when compared to other options available on the market, especially considering the drawbacks related to dark scenes.
Alternative options: Users who prioritize accurate black levels may find better alternatives in OLED or mini-LED TVs, which offer superior performance in displaying dark scenes convincingly.
