First Claim
1. A video display apparatus provided with a transmitting unit configured to transmit, to a video output apparatus, compatible video signal information including first information indicating a plurality of pixel numbers of video signal displayable by the video display apparatus and second information indicating detailed setting information required in order for the video output apparatus to generate video signal having one of the plurality of pixel numbers, comprising:
- a determining unit configured to determine whether a video signal received from the video output apparatus after the compatible video signal information is transmitted to the video output apparatus by the transmitting unit is a video signal having a pixel number displayable by the video display apparatus and being displayable by the video display apparatus; and
an updating unit configured to update the second information of the compatible video signal information, in a case where it is determined by the determining unit that the video signal received from the video output apparatus is a video signal having a pixel number displayable by the video display apparatus and not being displayable by the video display apparatus, such that the detailed setting information for the pixel number of the video signal received from the video output apparatus is included in the second information,wherein the transmitting unit transmits the compatible video signal information updated by the updating unit to the video output apparatus.

Abstract
Compatible video signal information having first information indicating a pixel number of a video signal displayable by a video display apparatus and second information that is setting information required in order for the video display apparatus to display a video signal having the pixel number is transmitted to a video output apparatus. In the case where a video signal received from the video output apparatus after the compatible video signal information is transmitted is a video signal having a pixel number displayable by the video display apparatus but not being displayable, the compatible video signal information is updated so that setting information for the pixel number of that video signal is included in the second information.
