The Sony X800D is a great choice if you are looking to use a 4K TV as a computer monitor, and want it to work well in everyday situations like watching movies, gaming or working, but don’t want to spend a fortune on a massive, high-end screen. Its advanced display technologies, wide input support, strong motion handling and low input lag will satisfy most people.
This model is offered in two sizes, 43 inches and 49 inches. The display panel used in each size differs; the 43-inch uses a panel with better contrast, but has a worse viewing angle while the opposite is true for the 49-inch.
Ranked in these QuestionsQuestion Ranking
Pro Great color reproduction
Despite the low price, this TV offers near-premium display specs and HDR functionality which separates this TV from its competitors. Sony’s Triluminos technology allows a much wider color gamut and more natural looking colors previously only found on high-end models. Pictures will look more dynamic and natural compared to other TVs in this price range, especially when using an HDR signal.
Pro Smooth motion for movies and games
The X800D’s strong motion control handling make it great for movies and games. At 15ms the pixel response time is better than its price range competitors which results in virtually no blurring or trailing with fast moving objects on the screen. Additionally, it supports black frame insertion, even in game mode, which further smoothes the picture and reduces eye tracking motion blur.
Pro Small details will look sharp and clear
The TV is a great monitor for tasks like text editing, web browsing, 3D modelling or other situations where detailed color information is needed for each pixel. It supports 4:4:4 chroma in PC mode or uncompressed color data for each individual pixel. It eliminates jagginess on text and loss of detail on small objects caused by pixels with inaccurate color data.
Pro Thin TV with thin bezels
The bezels are only 1 cm thin and TV itself is only 4.5 cm thin, so it will look good either on a wall or on a table.
Pro Attractive, compact stand
The stand is metallic and does not require much space on a table.
Pro Good frequency response
Low frequency cut off is at 90Hz and there are no major drops on the high frequencies, ranking this TV above average
Pro Picture enhancement
This TV has a special processor that enhances picture quality. The signal is broken down and sent to the display in several components (texture, outline, contrast, and color). Each one is separately analyzed and processed, to ensure the clearest, sharpest, most attractive final image.
Pro 49" model has good viewing angles
For the 49-inch model the viewing angle is very generous and can suit almost all situations.
Pro Handles reflections adequately if the room isn’t too bright
The screen has a semi-glossy finish which helps reduce reflections.
Pro 43" model has excellent contrast ratio
It has an excellent contrast ratio of 3900:1, providing a dynamic looking picture.
Pro Speakers suitable for daily use
This TV's speakers are okay for regular use at normal volumes, reaching 92dB which is enough for a mid-sized room. But for larger rooms it is recommended to buy a separate sound system.
Pro Good support for various input formats and resolutions
The X800D’s support for different resolutions and refresh rates, when hooked up as a PC monitor, is excellent.
Pro Input lag sufficient for casual gamers
Casual gamers will be satisfied as X800D delivers barely noticeable input lag of 33ms at 1080p and 35ms at 4K.
Con 49" model has mediocre contrast ratio
Contrast is about 1500:1 for the 49-inch model.
Con Separate power brick
There is a separate power brick on the 49” version.
Con Depending on the setting, inputs can be hard to access
Note that if the TV is mounted on a wall, some inputs are difficult to access.
Con 43" model has rather poor viewing angles
Colors start to shift at 20 degrees and a noticeable brightness loss begins at 40 degrees.
Con Somewhat lacking brightness
The maximum brightness of the set is 375 nits, which provides acceptable performance in sunlit rooms. HDR content, where brightness is needed, will look decent but lacks the peak brightness of higher-end models.
Con Distortion at higher volumes
Harmonic distortion is not a problem in low and mid high volumes, but the sound becomes heavily distorted at maximum volume.
Con Lacking black levels
Although the TV can reproduce colors brilliantly, provides a great picture in a dark environment and the shadows can be distinguished clearly in complex dark scenes. The black levels won’t compete with higher end models since it lacks local dimming, or the ability to dim the LEDs only on parts of the screen displaying black.
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 Input lag might be too much for pro gamers
If you are a serious first person shooter or racing game player, where every millisecond counts, the input lag may not suit you.
