Display suggests 3840x2160 in game despite display being set to 2560x1440??

[lettuce]

So i have a 50"" TCL QM8B TV that I'm using as a extended display on Windows 11. I have set the res of this TCL TV to 1440p via System>Display option in windows. When the TCL displays the windows 11 desktop pressing the info button on the remote reports that the display res is indeed 2560x1440 but when i load a game, in this case Helldivers 2, the TV reports that the res is 3840x2160!!!. I have the res in Helldrivers 2 set to 2560x1440 and set the display to number 2 (so the game displays on my TCL when loading automattically).

I have noticed in Setting>Display>Advanced display that the info for the TCL reports...

Desktop mode: 2560x1440, 120Hz
Active signal mode: 840x2160, 120Hz

Any ideas why the active signal is 4K when ive selected a 1440p res for this display and why it display at 1440p on windows but when a game is loaded it switches to 4k??

Got DSR,upscaling or nvidia ai super resolution turned on ?
Would activate once its displaying a game
In fullscreen
No idea what equivalent amd features are called
Though they likely have similar sort of things

Hmmm not sure, that new Nvidia app installed and still finding my way around it. But this is what its set for Helldivers 2...

Thanks for the replies.

DSR is off in NVCP
What should the Render scale be set too (if theres no 'off' setting) to stop upscaling?

EDIT:

Ok so there is no option to disabling render scale setting to ultra performance or ultra super sample doesnt change the res the TV reports at all still at 4K!!.

BUT, if i change the Display mode in the game settings from 'Fullscreen' to 'Borderless Window' then the TV does report a 1440p res. Is there a downside to having borderless window mode over fullscreen??

 

[lettuce]

Is there a "native" setting for Render Scale?

There is but doesn't alter the res still at 4K, only way seems to be borderless window mode then its at 1440p. Unless theres another option that would force it to be 4K

turned pc on now to have a look
i guess its game dependant
since your picture has options i dont have
i have render scale off
but in another game dont even have render scale option
but do have render resolution option instead

in the nvidia app
did you also check the global settings tab?
as i do have DSR in there perhaps enabled globally
would over ride individual program settings

also the softwares new so could be some sort of glitch i guess

edit
also what version number is your nvidia app?

Yeah DSR Factor is turned off in the global settings I do have RTX Dynamic Vibrance enabled however, but i dont believe that would alter the resolution

The Nvidia app is version 10.0.0.499/p

 

[lettuce]

may make no difference
but mines version 10.0.0.555/p

is there a way to update the app from the program itself, as i dont see an update option in the settings?

 

[lettuce]

Yeah have tried uninstalling and reinstalling, doesnt seem to effect anything.

Odd that it stays at 1440p when using Borderless window mode but not fullscreen mode

 

[lettuce]

Im wondering if the setings from the old NVCP are conflicting with the new app at all.

I should really load up another game and see if it does the same, maybe its just helldivers 2
