How to Adjust the Frequency in a Sony Bravia

By John Lister

A television's frequency, expressed in hertz, is the number of times each second that it refreshes the screen. Some televisions, including in the Sony Bravia range, use a much faster refresh rate than the original video footage. Such televisions can artificially create frames in between the "real" ones, the idea being to minimize the difference between each frame and thus make the video motion appear smoother. Although you cannot adjust the actual frequency at which a Sony Bravia television operates, you can alter the way it handles the additional frames.

Step 1

Press the Home button on the remote control to bring up the on-screen menu. Use the right and left arrow keys to select the "Settings Section," and then use the up and down arrow keys to select the "Picture Adjustments" setting. Change the "Setting Memory" option to a specific input if you want to change the way the display works for a specific input, such as the one for your Blu-ray player, or change it to "Common" if you want to apply the display settings to all inputs.

Step 2

Adjust the settings for Motionflow. This affects how your TV deals with the fact that it displays more frames each second than the original video footage. With "High" selected, the TV artificially creates the additional frames; "Standard" uses a combination of repeating some of the additional frames and artificially creating others; with "Off" selected, the TV does not create additional frames and simply repeats the original frames.

Adjust the settings for CineMotion. This only affects footage shot at 24 frames per second, such as some movies. This footage doesn't neatly fit the mathematical ratios used for the way many televisions process 30- or 60-fps footage for display at a higher frequency. CineMotion uses workarounds such as repeating some frames three times and others two times. Select the "Auto 1" setting to use CineMotion; select "Off" if you aren't happy with the effects.
