Define the Precise Framerate and Resolution of the Video

The majority of the Blu-ray players you find today come with an auto-resolution feature. This respective amount of resolution is defined by default to be compatible with HDMI output. That is to be compatible with your TV (through which you will see the output).

In general, most modern-day televisions come with 1080p resolution. Although this configuration is OK for many users, some demand something advanced. If you are one of them, you can alter the default configuration.

You can check the amount of resolution on the TV set simply by pressing the “Info” key on the remote. To change the framerate, you should go to the Setup Menu of the TV and then select the option “24p Output”. Through this option, you can change the framerate.

The Shape of Your TV Screen
