GUI screen truncated, Ganglion does not connect to dongle [resolved]

I'm trying to connect the ganglion to my Windows 10 laptop for the first time. All components (ganglion + dongle) are new editions as of Dec 11, 2020. Steps I've taken:
- Plug in dongle (computer recognize device and it shows up in "Device Manager" and in "Bluetooh & other devices" as "Bluegiga Bluetooth Low Energy (COM3)")
- Turn on the ganglion, which gets the blue light blinking
Blue light on ganglion never steadies to indicate it's connected to the dongle.
Also, OpenBCI UI doesn't show ganglion is connected.
What to do? Is this a known issue?

DTork, hi.
What do you see on the GUI connect process? It should look like this:

Hi William,
This is what I see in the GUI while the ganglion is blinking blue (trying to connect)
Does it matter that my laptop has only one USB port and it's USB 3.1?
Image was chopped off. Can you see that? Clicking on the BLED112 button should show a list of Ganglion devices.

I chopped it off because there was nothing down there. But here's the full image:
BOTH images are chopped off, you should see,
Where you click on the BLED112 button, then see the dongle listed.
I think it's the UI. It's not rendering fully on my laptop for some reason, even after following the instructions from here: https://docs.openbci.com/docs/06Software/01-OpenBCISoftware/GUIDocs#installing-the-openbci-gui-as-a-standalone-application
Are the instructions for "If you have a high DPI screen and are running Windows 10, you may notice that the GUI is hard to see, and nothing seems to scale correctly" up-to-date? Maybe that's where I should focus
Mentioning Richard @retiutut, the GUI developer. Are you indeed working with a high DPI screen? Can you use another monitor or change the resolution? It sounds like you are not seeing the full "Pick Transfer Protocol" menu.
I played with the settings and got it to work :-)
Under "High DPI scaling override" I selected "Application" instead of the recommended "System (Enhanced)"
And viola! the UI renders fully and correctly:
That's great. Thanks for your update.
Perhaps in the future, GUI could put up a warning box in the middle of the screen, if it detects possible display issues.
