I have traced this issue to a limitation of my monitor. The problem is that two of the three HDMI ports on this monitor are 4k@30Hz which do not work with the BIOS default resolution of 1280x1024@50Hz. This refers to the BIOS screen not the OS screen.

The third HDMI port on this monitor is 4k@60Hz and for giggles I tried it and there I see the BIOS screen. I also had success using a VGA port.

I will mark this thread as solved but I think this may be a bug in not correctly detecting this monitor's capabilities.

xhue,

I re-flashed but no change. It was worth a shot.

FWIW, a couple days ago I ran memtest86 on this board with the BR APU. No problems. So I don't think there's an issue there but the new APU changes the equation.

Thanks for the help!

P.S. if you still have your old B.R. with you, flash 5.70 again after you clear CMOS, i.e. install B.R. -> clear CMOS -> re-flash 5.70 -> install 240GE -> CMOS again -> boot.]]> Wed, 27 Mar 2019 06:33:25 +0000 https://forum.asrock.com/forum_posts.asp?TID=11182&PID=61750&title=athlon-240ge-apu-blank-screen#61750 https://forum.asrock.com/forum_posts.asp?TID=11182&PID=61749&title=athlon-240ge-apu-blank-screen#61749 Author: xhue

It looks like some nasty bug to me, still. 5.70 is very fresh and ASRock rarely do the job properly on the first attempt.

My advice - rebuild the whole PC from scratch. Tear it all down, piece by piece and then reassemble it back again. Pay extra attention to the CPU and the RAM placement. Clear CMOS for 10s and try booting again. ]]> Wed, 27 Mar 2019 06:28:17 +0000 https://forum.asrock.com/forum_posts.asp?TID=11182&PID=61749&title=athlon-240ge-apu-blank-screen#61749 https://forum.asrock.com/forum_posts.asp?TID=11182&PID=61743&title=athlon-240ge-apu-blank-screen#61743 Author: Micro_zom

xhue,

4.x, 4.50 I think.

I have recently read the Topic 'Bristol Ridge and 4.x BIOS'. As it was from 4.x that I updated to 5.70 I was pondering downgrading to 3.40(?) and from there upgrading to 5.70. With B.R. the 'Instant Flash' fails within BIOS Setup but succeeded via 'F6'(Instant Flash) with 4.x.

Does this make sense?

Thanks.

What was your previous BIOS version? I mean before 5.70?]]> Wed, 27 Mar 2019 02:29:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=11182&PID=61742&title=athlon-240ge-apu-blank-screen#61742 https://forum.asrock.com/forum_posts.asp?TID=11182&PID=61740&title=athlon-240ge-apu-blank-screen#61740 Author: Micro_zom

Hi,

New APU shows blank screen only. Previous APU (Bristol Ridge 9500E) no problem.

BIOS version is 5.70. (B350m Pro 4, rev 1)


With AC pwr disconnected cleared BIOS setting using the motherboard jumper on pins 2-3 (6sec). I've this procedure once since initial.

Power-up indications:

- After a few seconds the keybrd Numlock LED lights and remains lit (And responds to Numlock key taps). Hitting the Delete key causes a beep to be heard.

- The HDMI display I am using shows a screen resolution/refresh-rate popup box when changing to another signal source. Oddly, the monitor shows a resolution of 3840x2160@30Hz. IIRC 1280x1024 is normal for this board in BIOS.

- The CPU fan is running.

It seems to me the board is booting normally but the display is blank.

Feedback appreciated. Thanks.
