Where can I find a list of upcoming 4K events that will air on the 4K channel (910) ?

VideoTron Community, greetings.

You can usually get a list of upcoming 4K UHD events directly from your service provider by visiting their website or TV guide section. Some sources allow you to subscribe to receive updates or notifications about upcoming 4K material. Another great method to keep up with events happening in 4K is to use streaming programs, which provide you access to a variety of live sports and entertainment in high definition, including 4K UHD. This app is really useful if you want more live programming options than what your standard 4K networks give.

Good fortune to you!
