LG UK6300 55" (55UK6300PUE) vs Sony X900F 65" (XBR65X900F)

The UK6300 offers a responsive and lag-free gaming experience. It has low input lag and a good refresh rate.

The TV has one of the lowest input lags in the market – approximately 11.5 ms. The “Game” and “_PC_” picture modes help achieve this. Moreover, the latency increase while gaming in 4K or HDR is extremely tiny and doesn't go past 1 ms.

The TV is great for high-end console gaming. It has a 60Hz native refresh rate and you can game in 4k60Hz if you enable the “HDMI Ultra HD Deep Color” setting.

This TV is a great option for fast-paced content such as sports and video games due to the quick response time. This makes sure the content doesn't appear blurred out due to fast movement on-screen. A full pixel color transition on the TV's panel takes 15 milliseconds.

The UK6300 runs on LG’s WebOS. The interface is functional and easy to navigate.

LG Content Store has a wide range of apps, including popular media streaming services such as YouTube, Amazon, Netflix, etc., and many other third-party apps, which are all kept up-to-date.

The UK6300 is a good TV for rooms with wide seating because it offers a better viewing angle than other TVs at this price-point. The blacks are consistent at any viewpoint, and the color and brightness shifts aren’t too bad – they become noticeable at moderate angles. Colors shift at 22 degrees, whereas brightness shifts at 27 degrees.

The overall picture quality of the Sony X900F is on par with what the best, high-end TVs in its price range offer. The X900F offers excellent performance when it comes to both bright and dark scenes thanks to its ability to recreate bright and vivid colors as well as some deep blacks.

The Sony X900F does an excellent job of reproducing smooth and fluid motion thanks to its advanced flickering capabilities. The panel can flicker at the rate of 720 Hz which can eliminate motion blur. Only a few panels in this price range can flash that fast, which is good, as the majority of viewers will not notice such fast flickering.

Additionally, unlike the overwhelming majority of TVs present in this price range, the X900F can perform local flickering which ensures that the flickering doesn't take its toll on the overall brightness. Worth noting that the regular flickering of an LED panel reduces its brightness by about a half which can de-saturate some highlights and degrade the image.
