Philips monitors on black during boot up with Raspberry pi4
On my Raspberry pi 3 b my Philips 170 B monitor shows MM as it should.
After installing MM on a raspberry pi 4 the monitor ¨dies" during the boot up. It sometimes shortly shows some of the of de OS boot data, but than the screen turns to black.
I tried to edit configt.txt by enabling
Without a good result.
I also tried config_hdmi_boost=7 with no good result.
When I enable #hdmi_safe=1
It works but the resolution of the screen is not the good one (everything overlaps with to large fonts)
If I use an other monitor like a HP all works fine.
Any ideas what to do?
