Dear Render1967,
Thank you for the posting.

Today we took B450M Pro4-F R2.0, CPU 5600G and BIOS P3.10 to test and system can output the video via D-Sub properly.
Please refer to the below suggestions to verify the system.

1. Clear CMOS by referring to user manual page. 28.
User manual: https://download.asrock.com/Manual/B450M%20Pro4-F%20R2.0.pdf
2. Only install CPU, PSU, Cooler, RAM, D-Sub cable, Monitor to check if the system can boot into BIOS setup.
3. Update the BIOS to latest version
4. If possible, please use other CPU, D-Sub cable and monitors to cross test.
Thank you,

Best wishes,
ASRock TSD

Hi to all!
My PC configuration is: MB ASRock B450M Pro4-F R2.0, CPU Ryzen 5 5600G, RAM ADATA XPG GAMMIX D10 16GB (2x8GB) DDR4 3000MHz, HDD ADATA Ultimate SSD SU650 120GB + Apacer AS2280P4 M.2 PCIe 512GB, PSU FORTRON HYPER K PRO 500W, monitor ASUS VH222S. This monitor has only D-Sub, but there is no signal from the motherboard D-Sub. I tested with another monitor - there is a signal from the HDMI and DVI-D ports, but not from the D-Sub port. What could be the problem? Help me, please!]]> Tue, 22 Mar 2022 00:30:48 +0000 https://forum.asrock.com/forum_posts.asp?TID=22357&PID=94530&title=no-signal-via-dsub#94530
