What is your monitor default resolution and more importantly, what is it's
Pine64 has U-Boot support for DE2/HDMI, which has some pixel clock issues
which can influence Linux, unfortunately. At the time, there wasn't enough
knowledge to do it properly. I plan to update it after A64 DE2/HDMI support is
finished in kernel.
Meanwhile, can you test if it works for you either with disabled DE2/HDMI in
U-Boot or if you apply this patch to Linux:
