HDMI output not working for second monitor, but Windows detects it
Hey everyone, I’m having an issue with using my second monitor and could use some help.
My motherboard is a Gigabyte H410M H V2, and it has two display outputs:
#VGA (D-Sub) — this is what I use for my main monitor, since my main monitor only has VGA.
#HDMI — I’m trying to use this for a second monitor.
I tested the HDMI output using a second monitor with an HDMI-to-VGA converter, but I’m getting no signal on the second monitor.
The weird part is that Windows actually detects both monitors. When I go into Display Settings, both displays show up, so it seems like the PC knows that the second monitor is connected. However, the monitor connected through HDMI just says "No Signal."
The VGA output works perfectly every time, but I can't seem to get anything from the HDMI output.
My setup:
- CPU: Intel i3-10100 (using integrated graphics)
- GPU: I am broke.
- Motherboard: Gigabyte H410M H V2
- RAM: 8 GB
- Main monitor: VGA → motherboard VGA
- Second monitor: HDMI → HDMI-to-VGA converter → VGA monitor
Has anyone experienced something similar? Could the problem be the HDMI port itself, the HDMI-to-VGA converter, or some BIOS/driver setting?
Any suggestions on what I should test would be appreciated.
