how you mean download? My several TFT's (7", 5" etc.) does not support EDID, so
i must configure this directly in the bbb. But i really don't know where and
how all this configuration can be done? With google i have found only manuals
for the raspberry.
thanks

But unfortunately for me, it's not clear how to implement this correctly in the
cmdline?
thanks

Hello all,
*I have try to understand export/unexport overlay with following link:*
https://learn.adafruit.com/introduction-to-the-beaglebone-black-device-tree/exporting-and-unexporting-an-overlay
But then i don't found the folder "sys/devices/"
So i have try to remove the # at the line
#cape_d
of edid real failures, uncomment this next line:
>>

>> *cmdline=coherent_pool=1M quiet cape_universal=enable
>> video=HDMI-A-1:x800@400e*

now hdmi is working, i don't know why, i have deleted the last empty line,
and actived the second cmdline instead the first
*so i am only looking for a solution regarding this "bone_capemgr.*"
why i cannot find this file?*

activated)!!

Hello all
I have a TFT with 1920x720, and I try to control this with the HDMI from my
BBB.
I am trying with cmdline
cmdline=coherent_pool=1M quiet cape_universal=enable
video=HDMI-A-1:1920x720M@30e
this disable the hdmi-output
but i think the output is randomly... actually the resolution is 6
dr --output HDMI-0 --mode 720x480 --rate 60
No protocol specified
Can't open display :0.0
root@beaglebone:/# xrandr --output HDMI-0 --mode 1280x800 --rate 60
No protocol specified
Can't open display :0.0

with raspberry it's really much simpler!! :-(
=> I was successfully set up the output by simply adding a
command"hdmi_cvt=1920
720 60 0 0 0 0" in config.txt
