I have an ASUS Chromebox in kiosk mode and am able to rotate the display using Cntl+Shift+F3, but when I play a portrait presentation, the bottom half of the screen is white. the presentation and schedule show correctly on Windows players. Any ideas?

Wayne,

Is the presentation only showing it's top half, or is the top half of the screen filled with the entire presentation at an odd resolution?

the presentation is only showing the top half in correct aspect ratio.

Wayne,

Can you try setting portrait mode in the OS itself? Before Rise Player starts, press cntrl+alt+s, click the click at the bottom right of the screen, and click the resolution. Rotate the screen around an entire cycle.

It shows the full screen after a reboot. Strange but at least it works. Thank you

Wayne,

It's good to hear that cleared it up. You may want to check that you are on a fully updated version of ChromeOS as well.

The Chromebox is locked down in kiosk mode so I cannot get back into the OS. It is an ASUS box and I have tried the cntrl+alt+s 20 different times during bootup and can never get to a desktop. cntrl+shift+F3 is the only thing I found to rotate the desktop. Do you know if Chromeboxes will automatically update their OS upon reboots?

Wayne,

I don't believe they do.
