Thank you for replying. I booted the tinker board with the 7" display attached, had "no signal". Without unplugging anything, I used putty to remotely login. I ran sudo armbianmonitor -u. A dialog appeared saying "System diagnosis information will be uploaded to Please post the url in the forum where you've been asked for." I'm not sure if anything was uploaded or to where.
I just think its odd that this generic 7" works with everything but Armbian.
Here's a little more detail about the touch screen.
= 7’’ standard display, 800 × 480 resolution capacitive touch screen, maximum support 5 point touch
= Support backlight control alone, the backlight can be turned off to save power
= Supports standard HDMI interface input, compatible with and can be directly inserted with Raspberry Pi (3rd, 2nd, and 1st generation)
= Can be used as general-purpose-use HDMI monitor, for example: connect with a computer HDMI as the sub-display (resolution of the output has to be able to adjust to 800X480)
= Used as a raspberry pie display that supports Raspbian, Ubuntu, Kodi, win10 IOT, single-touch, free drive
= Work as a PC monitor, support win7, win8, win10 system 5 point touch (XP and older version system: single-point touch), free drive
= CE, RoHS certification
For Rasbian System, Ubuntu, Windows 10 it says to:
Modify the “config.txt”
Open the config.txt file of TF card root directory and add the following
code at the end of the file, save and eject TF card safely:
max_usb_current=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
Armbian doesn't use a config.txt file.....has the AmbienEnv.txt. Been reluctant to mess with it.
