12400F
CPU:
Intel Core i5-12400F
Monitor connected to motherboard HDMI
QUESTION
See the problem yet?
ANSWER
The CPU has no integrated graphics.
Intel CPUs with an "F" suffix (like the i5-12400F) do not have integrated graphics, so the motherboard video outputs will not work.
You need a dedicated graphics card and connect the monitor to the GPU (DisplayPort or HDMI).
Motherboard HDMI
(won't work with 12400F)
Use the GPU outputs
(DisplayPort or HDMI)
KEY TAKEAWAY
Just because a motherboard has HDMI or DisplayPort doesn't mean it will output video. Always check if the CPU has integrated graphics.
