Hi, I have 3 monitors with onboard graphic output: 1 VGA, 1 DVI to VGA and 1 HDMI to VGA.
But two of them will no screen randomly, only one will display normally.
What can I do now?
Ooh, I am using 2400G and my board is ab350 pro4.

Thanks.

Dear Szaki,

Greetings, this is ASRock TSD.


Regarding to your question, we provide some suggestions for verifying:

1. Please install AMD all in 1 with VGA driver from below link.

2. Please update to BIOS P5.40 to verify.
* Please install "AMD all in 1 with VGA driver" before updating to this BIOS.

3. Please connect the output display cable (HDMI, DVI-D, D-Sub) to the monitor directly instead of adapter.

4. If possible, please install another CPU/display adapter to verify.


Thanks!

All the best,
ASRock TSD
