EDID version of OLED55C6V or supported resolution detection

[dolbnya]

I have a mediaplayer connected to my TV OLED55C6V through HDMI. For every video playback the player tries to select an output HDMI signal format automatically depending on both video framerate/resolution and framerate/resolution supported by the connected TV to show the video as close to original as possible with the TV without any scaling. And here I have a problem: the maximum resolution the player selects is 1080p despite of the videofile has resolution 4k and the TV supports playback of the input signal up to 4K60p. I can change the output signal resolution on the player manually after blayback starting and it works, but it's not convenient. As far as I know the only way of getting information about videosignal format supported by TV for the player is EDID on HDMI channel. So is it possible to fix the issue? Maybe some hidden setting in TV could change the version of EDID?

The problem is successfuly solved. To make the TV reply via EDID that it supports 4K and Dolby Vision you have to choose screen mode Movie
