Sony XBR65X850F 4K HDR Ultra HD TV Review

Sony 850F

A Quick Look at Sony’s 65″ X850F 120Hz Smart LED TV

Sony’s X850F series is their entry level offering into its upper tier of premium class of 4K HDTVs for 2018 and is available in 65”, 75” and 85” screen sizes.

Note: The 65” and 75” models use IPS display panels with edge-lit LED backlighting. The 85” model uses a VA display and is illuminated with direct-lit LED backlighting without local dimming capability.

Since the 850F is the base model in Sony’s latest top tier lineup, it does not offer all of the features of its higher-end counterpart – the X900F – such as full-array LED backlighting, X-tended Dynamic Range Pro, X1 Extreme Processor, Dolby Vision and X-Motion Clarity.

But don’t let the absence of certain features deter you for inquiring about this otherwise very solid performing 4K UHD TV which certainly holds its own where good features are concerned and I’ll talk about in the next section of this review.


The appearance and design of the 850F is quite attractive and is very similar to the 900F with the exception of the TV’s stand which is not a typical looking Sony design, yet is still aesthetically pleasing and adds very good stability for the 850F’s 65” display panel.

The 850F’s screen contains a semi gloss finish and is surrounded by very thin borders (bezel) which are less than a ½” in width. The panel depth of this TV is also quite thin and measures just over two inches at its thickest point.
