I have a Corsair Xeneon 32QHD165 monitor, which is nice, but it has one big problem, and that is that you can’t enter the BIOS via the dedicated GPU. 

For me, an integrated GPU works, but it is a hassle to switch cables every time you want to enter the BIOS. 

It turns out that this is happening due to a slow handshake between the monitor and the GPU.

I was thinking that maybe there is a way to fix this by changing some settings or updating firmware, but no luck because there is not much you can change in the monitor settings. 

Since this is a monitor, it probably has a service menu that has more settings, but there is nothing on the internet about it, so I tried to brute force it so I could see if I could find it, and I did! 

How to enter the service menu?

1. Turn off the monitor
2. Then turn it on (1 button)
3. As soon as you press the power button, press and hold down the joystick.  (2 button)
4. Wait until the monitor boots up and shows the screen.
5. Open the menu by pressing the joystick. 

Now you will see the “F” option. Press the joistick again to enter the menu. 

Here is the service menu! 

Now, for me personally, enabling “DP CTS” fixed the BIOS post issue. 
This setting is used for debugging the monitor handshake, so that’s why it works. 

Also, I have changed the Energy to standard “STD”, and my monitor is now brighter. It was previously set to “ERP,” which is some setting for energy saving in Europe. 

I wanted to create this blog to save you guys, since I know the pain too. 

Enjoy! 😉
