Question DSRDL on native resolution 2560 x 1440.... DL Scaling 1.78x DL (1707x1563) ?

[SMN204]

RTX 4070
Please explain me why I see (1707 x 1365), (1920 x 1563) in DL Scaling DSR settings ? And what do these numbers mean ?
My native monitor resolution = 2560 x 1440 !

the same way DLSS works in games:
because the scaling feature will use these lower values as the output resolution and then upscale them to your display to preserve GPU processing and offer better performance.


look in Nvidia Control Panel
and in Windows > Settings > Display
to ensure your monitor is set at it's native resolution and refresh rate.

if so, you're fine.

Hmm. I'm not talking about DLSS, I'm about DSR.
With DLSS, the image is generated at a lower resolution than native and then scaled to the maximum resolution of your monitor. It's clear and straightforward.

And with DL/DSR it is just the opposite. The image is generated at several times your native resolution and then scaled to fit your native resolution !

And IMHO - with DSR I should be seeing instead 1.78x DL (1707 x 1365) ... a value larger than my native monitor resolution of 2560 x 1440 ... or am I misunderstanding the DSR scaling ?

 

[JohnBonhamsGhost]

with DL/DSR it is just the opposite

and DSR works in the same fashion as DLSS.
just increasing resolution and then downscaling to your display to increase fidelity.

the same way that DLSS decreases your resolution and then upscales to your display to increase performance.


you will still need to,

look in Nvidia Control Panel
and in Windows > Settings > Display
to ensure your monitor is set at it's native resolution and refresh rate.

what is your DSR 4x scale?
it should be 5120 x 2880.

if not, then your native resolution is not set properly
and/or your software is not properly detecting it.

DSR 4.0 - (2560 х 2048) 🙄

In Nvidia Control Panel my native resolution set is properly 2560 х 1440
And in Windows > Settings > Display... also correctly 2560 х 1440

or your software is not properly detecting it.

If that is the case, how do you fix it?
It's weird, visually I don't have any problems with the image and it's really 2560 x 1440.

P.S It looks like the "native' resolution for DSR is defined as 960 x 720.... 😱

i would first try running DDU from Windows' Safe Mode
and elect to remove all options for graphical data

after a restart
(re)download and (re)install the latest driver package, without GeForce Experience, for your GPU directly from Nvidia.

hopefully the reset would enable proper detection of your native resolution by Nvidia Control Panel

Performed uninstall using DDU, installed the latest video driver and..... all the same!
🙄🙄

couldn't tell you then.

why exactly did you want to use DSR?
don't think i've ever bothered with it through quite a few displays and lots of capable video cards.

I'm not going to use DSR. I just don't understand where the resolution data in NVP comes from ?

Maybe this confusion is because I have 5 monitors.
But in this example 4 are disabled in Windows and only one main 2560 x 1440 is working.
