Casting in 1080 about go-cast HOT 2 OPEN

Are you casting images? I know there is a hard limit on all versions of chromecast (Ultra too) that limit image casting to 720p. Other thing you might want to check is that your TV isn't doing overscan or anything like that.

Hello dKatsuro,

Thank you for your response! Allow me to add more information:
We are using a Grafana Dashboard (https://grafana.com/)
We have attempted to use both the windows Exe version and am currently running the Linux version of go-cast
The Dashboard is able to be casted from a "regular" Chrome on a workstation at it normal 1080 resolution to the same Chromecast
The TV is applying Overscan nor set to a certain resolution (in fact, there is no setting at all regarding resolution)

I am able to manually cast the same URL from my workstation using Chrome and the resolution is then 1080. Whilst if I cast using go-cast it is changing the format.

Do you have any other suggestions of what could cause this?
As mentioned, it seems to only occur when using go-cast to cast and any help would be greatly appriciated!
Go-Cast is saving us a mile of effort every morning (as we have used it to automate the casting of several dashboards now)
