Reason I ask, I use your beautiful utility to calculate modelines for the MiSTer FPGA project. The pixel clock rate is entered in kHz like so: hact,hfp,hs,hbp,vact,vfp,vs,vbp,Fpix_in_KHz
And these being obscure resolutions often, calculating the 4x, 5x and 6x size the 3rd decimal of the pixel clock becomes important.
Aside from this, thank you very much for making this incredible utility!

CRU already can if you add a detailed resolution in a DisplayID 2.0 extension block.

Hello,
I have a VPS with Windows Server 2022 on QEMU.
If I access it via RDP I can configure whatever resolution I want, when I login via VNC, Teamviewer or Chrome remote desktop the highest resolution is 1280x1024.
The default driver is the Microsoft Display Basic Adapter which I know doesn't support EDID overrides.



Actually CRU doesn't detect any resolution



I installed the official QEMU video driver which should support EDID, in fact I can see the original resolutions and I added 1920x1080



Unluckly after the driver restart and/or Windows reboot I can't see the new resolution



Am I doing something wrong?
Do you have any suggestion?

Thanks!

Alessandro

Terrific!! Thank you!

Hey guys,
I am trying to change the Freesync range of my monitor(Odyssey G7). Both entries related to that in cru are 80-240(detailed res, extension blocks) but the actual range is 64-240 when tested in nvidia pendulum. Any changes I make have no effect at all. CRU detects 2 samsung monitors but i make all the changes to the active one. Should I do it on both?

You only need to edit the active monitor entry. NVIDIA does not support default extension blocks and will ignore all changes if a default extension block exists. You need to delete the default extension block, add a DisplayID 1.3 extension block, and add 2560x1440 @ 240 Hz in there. Then editing the range limits should work. If not, try editing the CTA-861 extension block and add a FreeSync data block with the range you want.

The QEMU driver probably doesn't support EDID overrides. You might be able to change the preferred resolution using command-line options:
qemu -device VGA,edid=on,xres=1920,yres=1080

Unfortuntely this is a commercial VPS and I can't run any command to modify its settings.
This would have been the "cleanest" way to do that but I've found a different way by adding a virtual monitor.
Thank you

I made all the changes but it's not working. Did I make any mistakes?

I don't see anything wrong. What GPU do you have?

I have a 1660ti. Could this happen because lfc kicks in at 64 fps instead of the 80 that the default setting is? Would reinstalling the drivers or trying an older version make any difference?
