Dell Venue 8 Pro 5855 works perfect!

    I just noticed that I can't tune the brightness by press F6 and F7.

    It didn't bother me because I mainly just use the external monitor but it is an issue.

    Yue - 


    When in tablet mode, you can adjust the internal-screen brightness inside the of system-tray menu. It appears below the volume.

    When unplugged from both keyboard and the monitor/dock, do you see that control? If not, it's possible to enable using keyboards shortcuts, so let me know.

    Hi Forrest,

    Thanks for your reply.

    I don't see the brightness control bar in tablet mode nor in the plugged mode. There is just the volume control.

    However, if I press F6 or F7 on a bluetooth keyboard, the brightness control shows up at the right bottom corner of the screen, but the actual brightness doesn't change accordingly. It either 100% or just completely shut off when slide it to the very left.

    I usually keep it off, which is ok for me because I mainly use it as a chromebox.

    Ah ok - yeah it sounds like the adjustment is just not working at a deeper level - even if you could access the brightness bar in the system tray, it would work the same as the F6/F7 buttons on your bluetooth keyboard.


    Glad it's nothing big and that you can get some use out of the device anyway. Enjoy!

    What's the story on audio? I have the Venue 10 Pro 5056 and everything works but the Realtek ALC5672 audio.
