Sony X900F 55" (XBR55X900F) vs VIZIO D-Series 43" (D43-F1)

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.

The VIZIO D-Series offers decent gaming experience thanks to its high overall responsiveness and excellent motion handling. The gaming feels lag-free because of the TV's low input lag that measures at only around 22.2 milliseconds.

The VIZIO D-series runs SmartCast which is free of ads.

The motion on this TV looks smooth and clear thanks to the TV's pixels that can change their colors very fast as well as the optional black frame insertion feature that works at a high frequency.

The TV's full pixel response time measures at only 12.1 ms - fast enough to eliminate long traces of the artificial motion blur.

Additionally, the motion looks clear, and the details look sharper thanks to the TV's black frame insertion feature. This feature allows the TV to insert black frames in between of the actual content frames. This makes the details appear definite.
