We have also seen some monitor-specific sensitivity. Are you able to try a different monitor? We have had success on a variety of monitors that support 1920x1080. There are only a very limited number of resolutions supported. I believe 3840x2160 or 1280x720 may also work. If your monitor doesn't support one of those resolutions, that could be the problem.
Are you able to try your cable combination with some other hardware to make sure the adapter and cable are good?
You can try to reset the board after it's booting up. For me it works with this resolutions 2560 x 1080 and 1280 x 1080.
FML...brand new HDMI cable....doesnt work.....thanks all
