📎 AI Summary:
The thread discusses a problem with a dual-monitor setup where the second (HDMI-connected) monitor fails to turn on automatically when the PC starts. The original poster found a workaround by launching a game to force the monitor to activate but seeks a more reliable solution. A responder suggests that the issue may stem from how the PC detects signals from different graphics sources, implying that connecting both monitors to the discrete GPU might resolve the problem, which the original poster plans to try.

So I have two monitors on my pc one connected by VGA to the CPU and one connected with HDMI cable the GPU. Its kinda wank and I don't how windows managed to make the monitors work but they do except every time I turn on my PC the second monitor doesn't turn on. So I have found a stupid way to work around this by: Get this TURNING ON A GAME like apex legends which resizes your screen in the process magically turns on the second screen. Yes, the Windows key + P then setting it to extend does absolutely nothing, it changes the setting back when I exit the menu. So do you think there is another way to solve this issue so I don't have to turn on a game and wait every time I turn on my PC? Sr for my broken English, sometimes I don't even notice it, I am not a native speaker

To clarify the CPU is just the chip that crunches data. I believe you mean it's plugged into the motherboard which have a built-in lower performance graphics card and a second discrete graphics card plugged into a PCI or PCI-e expansion slot. While modern computers can run just fine with multiple graphics cards you will probably be better off running both monitors from one card. Computers should follow a port priority which isn't often documented in which they try to detect a signal.

My theory is your computer is detecting the first monitor on one GPU and stopping detection and uses that GPU.

Alrighty then I will try to buy another HDMI cable so I can plug the second monitor in the GPU and then post my result

Edit: Yes I only have one HDMI cable that is why it isn't plugged into the GPU just couldn't be bothered to buy another one :)
