Edit: Every custom resolution works so long as it's not a custom mode line (native pc, exact, etc all work except manual for some reason)

I managed to pull of 1280x720@295, but it would be really nice to get custom modelines working on this monitor. Do you happen to know why the custom timings don't work?

Well, "Exact" is a custom timing. It's up to the monitor's firmware. Some monitors are generous and will accept most timings, while others are more strict or might not have any obvious logic. I once had a monitor that would accept 80-83 Hz with certain timing parameters but not 75-79 Hz no matter what I tried. It's basically trial and error.

It might only support certain combinations of resolutions and refresh rates. It might reject a resolution if the horizontal or vertical blanking is too low. It might only accept timing parameters that are similar to certain standards. Horizontal values that are multiples of 8 are more likely to work. Reducing the vertical back porch is most likely to work first, followed by the horizontal back porch.

"Native PC" for 1280x720, 1600x900, and 1920x1080 match the timing parameters it supports by default for 60 Hz, so those resolutions might behave differently.

Those are GCN GPUs, which should support interlaced, but I don't know if the driver includes support for it. If it does, it would be with HDMI only.

Yep! It was most likely the vertical blanking being too low. All the resolutions work now albeit with a very very slight increase in pixel clock. Thank you so much though

Also do you know why there isn't a ycc422 and 10bpc setting in Intel graphics command center? It's only RGB or ycc444 for color format and 8bpc and 12bpc for color depth.

Hi all, I'm trying to set up real display scaling (so that the non-native resolution is displayed non-native in the monitor menu, for example 720p in game and 720p in monitor menu), qhd 1440p165hz (display port) and second monitor 1080p60hz (hdmi), when I try to change something in CRU, windows stops loading and I get a gray screen and disabled keyboard and mouse (second monitor completely turns off) or it only loads from the second time, I don't understand what could be the problem. I like the display scaling behavior better in non-native resolutions, and I want to use it always. I just need to put a couple resolutions into real display scaling mode.

The confusing part is that if I set everything up and restart the driver (restart64), everything works perfectly until I restart the computer like in the example above.

If this is an NVIDIA GPU, it's a driver bug that needs to be reported to NVIDIA. Does it still happen if you disconnect the second monitor?

If you edit the HDMI data block, are YCbCr 4:2:2 and 30-bit deep color enabled?

Is there a way to "test" the custom resolutions with my intel iGPU? im using HDMI to VGA adapter but 256x240p120hz is not showing up on windows node list, when i had a 980Ti they didnt show on windows node list neither but i could force the display to stick to it by making the resolution on CRU, restarting and then making the resolution on NCP and hitting "test" , is there a "test" functionality for CRU or something? i really wanna try 240p 120hz again.

The boot resolution isn't controlled by the EDID. If it's a BIOS machine, it usually boots in text mode, and then Windows switches to a graphics mode for the boot logo. If it's a UEFI machine, the resolution depends on the firmware. You would need to find out what resolution it's trying to send. Usually it's one of the 60 Hz established resolutions.

I'm talking about bootlogo windows, as I said earlier on hdmi the resolution and aspect ratio are correct, on display port it's broken like 4:3, I connected another monitor in it everything is displayed correctly from both ports. This is 100 crooked edid for the monitor with displayport. pls tell me where to dig?

So I have a lone CTA-861 extension block which only has an hdmi support data block and nothing else. 4:2:2, 4:4:4, 30bit, and 36bit checked.

The other CTA extension blocks only contain detailed resolutions. I've tried adding hdmi support to all of them with the same configuration, but still no settings showed up after using restart 64 and rebooting

I'm not sure why it wouldn't be working till now. The intel graphics driver is up to date as well.

Yes, the gpu is nvidia rtx, with the second monitor disabled everything works fine, what can be done about it?

I would like to note that the first time I set up scaling via display, everything worked the first time with both connected monitors. I don't know what happened, but at some point on reboot I got a gray screen, and I've been trying to solve it ever since
