In previous versions of the C317 indoor monitor from at least a couple of years ago, the web browser was integrated with a button to output the main panel, it could even be dragged and placed in any other point of the display.
In the latest updates, this has changed and there are now three buttons. BACK/EXIT/TABS
In my case, I use the web browser with the intention of opening a display redirected to an IP running on a BMS.
The modification forces the display to change its size and not be seen in full screen, since these icons appear below. With the other icon, the button was above the display.
