"If you want interlaced video to work correctly with xrandr you are going to have to manually interlace it yourself since the interlace option is broken with modern gpus. Set the width of the resolution mode to what you want the full width of the output resolution to be. Set the height to be half of whatever desired height that you want for the resolution. Then use the --scale 1x2 option when outputting that resolution mode (this doubles the internal height of the image). It will look very blurry when nothing is moving on your screen vertically; however, in motion everything will look just fine and will in effect achieve the full resolution that you desire."


does that scale option truly turn the Linux rendering into interlaced scan?

That's just scaling the image down, so that's not the same. That's basically supersampling in the vertical direction.

some guy said that cyberpunk read his 1440x540 resolution as 1440x1080 when doing this, so even if its not real interlacing, it is similar? he said he was able to push 160hz on his crt thanks to this.

It's not similar at all. It's like using DSR/VSR to scale 1440x1080 down to 1440x540. You can actually do this in Windows with the NVIDIA control panel by creating a custom resolution and setting the display mode to 1440x1080 and the active pixels to 1440x540.

Hello there,
Lately i was playing with cs2 crosshair placements i use special overlay to make my crosshair 1 pixel thickness so gap in my crosshair is 1pixel making it not symethrical since normal resolutionas are having even number of pixels making middle of my screen some border of 4 pixels instead of one pixel in the middle. I been trying to achive this i even got working 1439x1079 resolution but everytime i try setting CRU resolution to "Exact Reduced" it goes back to manual making game stretched... making crosshair incorrect i wish i could make game not windowed or without black bars but still having uneven number of pixel in height and width. Any ideas why it may keep changing back to manual?

Does anyone has XL2566K?
if so, can you share the edid of your monitor?
Thanks

The dialog always opens in manual mode. The timing options are there to help you fill in the values. It's not a setting. The values are saved. That has nothing to do with stretching anyway. Scaling is controlled by the monitor if you're using display scaling or the GPU if you're using GPU scaling. If you have a 1920x1080 monitor, how would you display 1439x1079 without stretching and without black bars? If you center it without stretching, there has to be black bars.

Yeah so the case is... making blackbars would make game not stretched, but what i want is to make game stretched yet to have uneven number of pixels in width (since height is not a problem i will be just 1pixel short since its 1079) I was just mistaken about "Exact reduced" i thought it needs to be set on like some kind of mode. Thank you for clarifing it to me i think i will find the solution myself .

Nothing offers that kind of scaling, but you can use both display scaling and GPU scaling to do what you want. Make the first detailed resolution 1919x1079 to make it the native resolution and set the monitor to display it 1:1. Then add 1439x1079 and use GPU scaling to stretch it to 1919x1079. The problem is that would still stretch the crosshair horizontally. You can't scale just the game and not the crosshair with custom resolutions because the crosshair is part of the video output.

I used cru to delete a few resolutions and now I've lost hdmi audio from nvidia. I tried to reset in and out of safe mode but no audio. Anyone can help? Thx?

Running reset-all.exe and rebooting should have reset everything. Is there no HDMI audio device? What does it show in the NVIDIA control panel and the Windows sound settings? Make sure the audio is set to the correct device and not muted. If all else fails, reinstalling NVIDIA's driver should fix it.
