That's a GPU-scaled resolution. The active resolution is still 2560x1440. If you change the timing standard to CVT reduced blank, you should see the same split screen problem if your monitor can't handle the resolution.

yes your right but why can i run on native 2560x1440 @180hz then and it says display scaling in nvidia control panel

so if i run native 2560x1440 @180hz and display scaling in nvidia control panel its still gpu scaling?

so if i run native 2560x1440 @180hz and display scaling in nvidia control panel its still gpu scaling?

So all i want to say is when i go back to native in nvidia control panel, and select no scaling and display scaling, its display scaling or gpu scaling then i really can't play with tons of input

The native resolution is not scaled. I was talking about the custom resolution. You created a GPU-scaled custom resolution with the NVIDIA control panel. You told it to scale 2360x1440 to 2560x1440 because you didn't change the active resolution, so the monitor sees 2560x1440, which is why it displays correctly. CRU created a resolution that's sent to the display, so the monitor sees 2360x1440, but apparently your monitor is not displaying that correctly.

I understand the basic workings of CRU, but I’ve never been able to figure out how people actually deduce what timing info to put in on their respective monitor/refresh rate.

Currently trying to setup 23.976 playback at 4k for MADVR, but MadVR’s custom timing optimization isn’t appearing for me, so I’m stuck figuring it out manually. Could someone point me in the right direction?

So whit native i have the same input delay as i would have 2360x1440 via cru?

You tell me. You're the one with the hardware. If you use display scaling, the lag at 2360x1440 would depend on the display. If you use GPU scaling, the lag at 2360x1440 should be the same as native, but you said that adds tons of lag. If that's the case, you should be able to easily tell if it's GPU scaling or not.

You would need to somehow measure how much the actual refresh rate is off by and then create a custom resolution to compensate. This will calculate the totals and pixel clock needed to hit a certain refresh rate: https://www.monitortests.com/pixelclock.php

MadVR will show me the deviation off the current clock. Can I use that to figure out the right timing? I’m also a bit confused by what I’m getting off the calculator. When I input 4k resolution at my frame rate, none of the pixel clock results are for 3840x2160.

The results show the required totals including blanking as shown in CRU.
