Hello.
I've installed FreeBSD 14.2-RELEASE on both my boards (RockPro64 and Khadas
Edge V),both based on the Rockchip RK3399 and I've used a display that has
a resolution of 720 x 720 resolution and I saw that the screen remains
almost black (almost because I see a dim illumination coming from the
display) .
I don't even see the u-boot logo. Instead,it is able to turn on my large
HDMI monitor,which has a resolution of 1920x1080 pixels.
Since I'm building a FreeBSD modular phone, I want to use a small HDMI
display with a low resolution. My question is : why is u-boot able to turn
on a monitor that has a resolution of 1920x1080 and it's not able to turn
on the other HDMI display that has a resolution of 720x720 ?
Or even better : what's the lowest resolution that will work ?
If I want to buy a display that has a resolution of 800x600,will u-boot be
able to turn it on ? 1024x768 ? more ?
Thanks.
