The reason I ask is based on the information here:

https://elinux.org/Beagleboard:BeagleBoneBlack_HDMI

  

In the past I've had the most success using an external HDMI to VGA connector 
that then feeds into a Viewsonic LED 1080P Full HD monitor.  VX2753MH-LED.  
This one doesn't really like 1920x1080@30 so the Beagle has trouble talking to 
it.

https://www.viewsonic.com/nz/products/lcd/vx2753mh-led

  

  

Do these smaller displays present as 30Hz?  Seems given the capabilities of the 
BBB it might be better to target a small 7" to 10" LCD display in the 1280x768 
size.  I know I had a lot of trouble with the Mango screens for the Replicape 
project with the higher resolution.   Touch on the Manga1 was crap.  Support 
for the entire project kind of vanished and now it turns out one of the stepper 
drivers is toast.  Never really got far with the Manga2 after all that

  

But the point is the higher res screens on a small physical footprint don't do 
much so I was curious about this display and how well the touch actually worked.

Touch is currently not calibrated.

But on my WIN10 PC it works fine. Can recommend the display.

Hi Robert,

it's solved. Hardware, the USB connector. 

Was able to solder, now it works fine.

Sometimes there was a second entry with lsusb. Then I found out, it's the 
connector, with a little pressure it worked.

Then microscope, solder iron

I spent 2 days and nights on that 

But I learned a Lot

Thanks to all

Hi Robert,
it's solved. Hardware, the USB connector.
Was able to solder, now it works fine.
Sometimes there was a second entry with lsusb. Then I found out, it's the
connector, with a little pressure it worked.
Then microscope, solder iron
I spent 2 days and nights on that 
But I learned a Lot
Thanks to all
Kasimir

Hi Dennis,
yes, the board looks similar. Of course I powered with a separate power 
supply :-)
That's my board:
https://www.ebay.de/itm/174109565997
Works fine on Windows PC, so it's not defective.
I like it, brilliant colors, wide angle  but Beaglebone Black is 
ignoring the touch.
I'm using the current IOT Debian buster image.

Could you be having a conflict with the native LCD system (which is
active in parallel with the HDMI). The native LCD system expects a
capacitive touchscreen on the P9 (I think) pins.

Might help if you identified WHICH product you are using. This one
https://www.amazon.com/GeeekPi-1024x600-Capacitive-Monitor-Raspberry/dp/B075QCXLPF/ref=asc_df_B075QCXLPF/?tag=hyprod-20=df0=309707619534==g=5324710204179150785c===9017241=pla-570706414713=1
mentions a "free driver" (I would hope so -- I doubt they'd sell many if
they said the driver was extra cost; though the best documentation I find
for it says "driver-free" -- meaning no driver needed).

I would note that the compatibility list on

does NOT mention beagle bone, though the body text does.

"""
Power Supply 5V/1A via USB port
"""
OUCH! Beagle USB maxes out at 500mA (which is the spec for USB2); you'll
need a powered USB hub with high-power ports.

"""
Please make sure the FPC cable is fastened and please connect the
MicroUSB cable to your device so that it can communicate with the touch
panel.
Please make sure the USB power cable is connected properly.
"""

Implies one needs to use a separate USB power supply

One port is power, the other is data.
