NOTE: Some TV models will display the message INVALID FORMAT when this error occurs.
This error message occurs if the computer is outputting a resolution signal that the TV does not support. Change the output resolution in the Display Settings of your computer to resolve this issue. Selecting 1024 x 768 normally works, but sometimes selecting a higher resolution may be necessary.
IMPORTANT: You may need to restart the computer after changing the output resolution so that the HDMI® input on the TV can recognize the signal.
NOTE: The method to change the output resolution depends on the computer operating system. If necessary, contact the manufacturer of the operating system or visit their website for information.
