Description (last modified by )
Fresh installation of Haiku, built in a Linux host, from git master 8341933096ea21251fd26a216168f8b0beff7781 (Fri Feb 8 00:17:07 2019). Haiku boots and displays the list of seven startup icons but later (presumably when the generic video driver is replaced by the hardware-specific driver), the screen goes blank.
lspci output is:

This is probably related to a confusing or nonsensical EDID returned by the display. I don't know what can be done about this in Haiku. Related to https://dev.haiku-os.org/ticket/13547

I have a Radeon HD 5450 PCI-e 1x that has the identical symptom on boot when it is the only card installed, on Walter hrev52853, x86_64. It gets through the icons, blanks, then nothing. If I install my older Radeon 9250 PCI, I can boot with the 9250 driving main monitor, with second monitor plugged into HD 5450. I get the multi-monitor selections in Screen prefs. The HD 5450 will not wake the monitor attached to it. This is same either upon boot or apply in Screen. Same if I swap monitors between cards. Only the 9250 works. Either monitor works normally when plugged into 9250. Both are 1440x900 Dell 19" lcd, using vga port.

Let me dig through that box a bit. It has been hibernating for quite some time. So have I.
https://dev.haiku-os.org/ticket/13547 is fixed now so I no longer believe it is related to that ticket. The only difference is that the NUC described in this ticket is connected via the HDMI interface to the display, and the computer described in https://dev.haiku-os.org/ticket/13547 (a Wyse D10D thin client) is connected via DisplayPort.
