Reasons For

Panasonic TX-40DS400 Sony KDL-40RD453
6 Reasons For
Faster Motion Interpolation Frequency
The Panasonic TX-40DS400 is a 400Hz motion interpolation frequency TV. That's 200Hz faster than the Sony KDL-40RD453 (200Hz).

The motion interpolation frequency is the frame rate which the TV is able to artificially create by inserting additional frames into the picture between the frames included in the original video source.

A faster motion interpolation frequency will result in smoother action scenes, less motion blur and a more life like image.

Read more Read less | Edit
10W Higher RMS Rated Power
The Panasonic TX-40DS400 has an RMS rated power of 20W, whereas the Sony KDL-40RD453 is only a 10W RMS rated power TV (10W lower).

RMS rated power stands for Root Mean Square rated power and it is typically used to measure the power output of the audio element of the TV.

A higher RMS rated power means that the audio system on the TV is more powerful and will be able to play the audio at higher volumes. A higher RMS power may also result in better quality audio at normal volume levels.

Read more Read less | Edit
Internet TV
The Panasonic TX-40DS400 supports internet TV, whereas the Sony KDL-40RD453 does not support internet TV.

Internet TVs allow you to access the internet directly through your TV. Connect your TV to your local network though WiFi or an ethernet cable.

Internet TVs let you watch movies and TV on the internet by connecting directly to services such as BBC iPlayer and YouTube without a computer.

Read more Read less | Edit
Wi-Fi
The Panasonic TX-40DS400 supports Wi-Fi, however the Sony KDL-40RD453 does not support Wi-Fi.

A Wifi (wireless LAN connection) on your TV means that you can connect your TV directly to your WiFi network.

A wifi connection means that connecting your TV to the net will be easier and can be done without cables.

7 Reasons For
Thinner
The Sony KDL-40RD453 has a thickness of 66mm. That's 22mm thinner than the Panasonic TX-40DS400 (88mm).

The thickness of a TV measured from the back of the TV to the front of the TV. Curved TVs will have quite a big depth as this dimension is measured from the back of the centre of the screen to the front of the edges of the screen.

A thinner TV has the advantage of appearing more elegant and will also mean that the TV will not stick out as much when mounted on a wall.

Better for Watching Films
The Sony KDL-40RD453 is better for watching films than the Panasonic TX-40DS400.
When ranking TVs for their suitability to display films, we’ve concentrated on several key attributes. These include contrast ratio and local dimming, which allow the dark colours on the screen to look deeper and richer - helpful for nighttime scenes. Also the screen resolution plays a part - 4K and higher resolutions mean that the image will be clearer and more detailed. Finally the size of the screen is also important - explosions and big dramatic reveals are so much more effective when you don’t have to squint to see the screen!

Better for Watching Sport
The Sony KDL-40RD453 is better for watching sport than the Panasonic TX-40DS400.
When ranking TVs for sport, we’ve concentrated primarily on the most important attributes. First off, we concentrate on the ‘motion interpolation frequency’. This is important for fast-moving spots, since it reduces the amount of blurring on screen. We also take the size of the screen into account - sports matches are far more immersive when viewed on a giant screen! Finally, we look at display brightness and display resolution, so that the games always appear as fully-detailed and bright.

Better for Playing Games
The Sony KDL-40RD453 is better for playing games than the Panasonic TX-40DS400.
When ranking TVs for games, we’ve concentrated on a number of key attributes: primarily ‘motion interpolation frequency’ and ‘high refresh rate’. Both connect to the quality of the image coming from the games console to the TV - both reduce instances of blurring caused by fast moving objects on the screen, and allow the image to appear more detailed and cleaner.
