The VideoLAN Forums

I have a Chromecast (2018 model) to which I happily render video from within VLC on my desktop computer. I have some videos which are in 16:10 or in 4:3 format, which the Chromecast renders with letterboxing. I would like to crop these videos to 16:9 so that my TV screen is used maximally. Unfortunately, the setting responsible for this on my TV (setting the TV's aspect ratio to "16:9" instead of "Just Scan", this is on a Sony Bravia from I believe 2013) seems to be disabled for the Chromecast: if I connect my PC via an HDMI cable, these options are available, but the Chromecast seems to have disabled my TV's settings menu (the button on the remote doesn't do anything). I've seen that there are Android apps (e.g. https://play.google.com/store/apps/deta ... .localcast) which can instruct the Chromecast to crop the video after having rendered it, but I could not figure out how to make this happen in VLC. Is it possible to have VLC request the Chromecast to crop the picture?

VLC 3.0.16 (win 8.1)
controlling aspect ratio of video rendered by chromecast.
Was able to accomplish this by
Tools > Preferences;Show Settings : All > Stream Output > Sout stream > Transcode : Use "Video Width" and "Video Height" to manually input the resolution information for desired aspect ratio. increase width until black margins dissappear.
