It seems like in our effort to make this simple, we have made it a little confusing! Basically, the situation is this:
- The “small screen” message is shown if the window is less than 64rem wide.
- ‘rem’ is a unit of size defined relative to the font size of the “root element”. This font size is device and user specific, but is usually set at 16px. Thus 16px times 64 relative units = 1024px. If the font size is larger, either because the user has increased it or the operating system sets a larger one, this value will increase. This will in turn mean that the window will need to be wider to avoid the “small screen” message.
- To be clear: “window” means the size of the viewable area of the browser, and not the display’s total resolution. It also does not include parts of the browser UI, such as menus, toolbars, or sidebars.
I suspect that what is happening is that your user with the smart tv as a monitor is either using the window scaling feature of windows (which will scale the effective resolution of their display down), or is using a larger font size (which will scale the effective width requirements up). Either of these would cause the message to be shown when the screen seems to be large enough, when in fact it isn’t.
What I can say for certain is that anyone who sees this message is using a screen that is definitely too small to properly display the network canvas interface.
