Can you clarify what you did and what your results were?

From what I understand, you are using a GTX 970 card with a "digital connection to the display." Is that DVI? HDMI? DP?

Are you saying that with 355.98, you have working scaling options in the Nvidia Control Panel?

I can try. 😉
I am using a GTX 970, which is not officially supported under WinXP. I modded the 36x driver according to the link provided above. I now need to mod the 355.98, but I just cut and pasted the modded file from the 36x driver instead. I used a DVI cable to an old DELL U2412M. But I just checked, I also have a working scaling option with display port (black bars left and right) to the old DELL. The 970 can also output just the original pixels with the "no scaling" option. The card then uses say sharp 800x600 pixels, with black borders on all sides on the DELL. As far as the DELL goes, scaling works in DVI and DP.

As the DELL screen has no HDMI, I just linked up the card to my 4k philips with HDMI.
Results on 4k: No scaling option with HDMI nor DP. However, I could not run WindowsXP in native 4k anyway. When I picked the resolution, the screen went black and never came back.

Just in case you wonder, if I switch the SSD and run the same hardware with win11, I do have all the options in 4k in HDMI and DP. And they seem to work at the native 4k resolution just fine. Atm, I can't check win7, I'd have to restore an image first.

Thanks for the response. What I really wanted to know was if your Nvidia Control Panel "Adjust desktop size and position" section 2 had scaling options available? I think in reading your answer you are saying 'yes?'. I have never been able to get these options.

However, I recently learned that one could run a cmd command to force the driver to do aspect ratio scaling, and it is working well for me, even though I can't change the options in the Control Panel UI.

If you test you'll find Radeons are more suited for builds like these. A given GeForce is either not as compatible or not as fast.
