1) Never use VGA if you can avoid it, it's an analog signal and is subject to
interference and noise.
2) Full HD doesn't work through VGA either (with DA200).
3) Just get a dongle that has DisplayPort. A USB-C -> DisplayPort dongle can
output at 4k @ 60Hz, so that will work nicely. The DA200 dongle does not have
DisplayPort, unfortunately.
