Windows 10: How to change my active signal mode?

My monitor usually displays 2560 x 1440 240hz. For some reason the active signal mode is changed which has made my monitor to be capped at 60hz. I tried changing to 240hz but there was no option for it.I had went on list all modes and i cannot find the resolution that i need which is 2560 x 1440 240hz but in this case i can only see for 60hz and there is no option for 240hz. I have tried various ways of changing it through NVCP which still did not work

Unable to change active signal mode

Hello, hoping someone can help because this has really been bothering me for a while! I have windows 11.

The issue is that I am not able to use my laptop with my projector.

I have bought 3 different connectors and I can use them with other projectors so they are not a problem. But when I press 'duplicate' or 'extend screen' nothing happens.

I think I may need to change the 'active signal mode' but I can't. I have gone to System - Display - Advanced Display - Display adapter properties for display 1 - list all modes - and then I change it to a different resolution. However, this changes the Desktop Mode, not the Active Signal Mode. So how do a change the active signal mode? Or what may be the reason why I can't use my laptop with my projector?

Really hoping someone can help me!!!

Many thanks,

Holly

 

Forcefully changing "active signal mode"

Hi Austin,

I'm Rodrigo and I'll help you.

On System->Display->Advanced Display -> Display adapter properties for Display 1 -> List All Modes you don't change the active signal mode, on you only list the modes that the display supports.

A way to change it is on the Graphics Adapter Control Panel. Depending on your hardware and where the display is connected you will find it in the Nvidia Control Panel, Intel Graphics Command Center or Adrenalin Software.

What do you want to achieve changing this setting?

 

Forcefully changing "active signal mode"

Hi there.

I've been through all the forums and the proposed solutions have not worked for me.

I need to find a way to change the active signal mode of my display (not only desktop mode).

I have made sure my display driver is up to date. I have tried changing the display through System->Display->Advanced Display -> Display adapter properties for Display 1 -> List All Modes. And I've done this by changing the display adapter a couple of times, back and forth, and no luck.

Can you please let me know if there are any alternative methods?
