Previously working 2560x1080 monitor now can only be set to up to 1920x1080 after driver update (580.105.08). If driver is uninstalled, the monitor will correctly default to 2560x1080 meaning this is not a problem with EDID. GPU is a GTX 1080. Problem is irrespective of compositor being used.

I confirm this happened to me as well. After upgrade to 580.105 with HDMI it detects wrong resolution. Native is 2560x1440@59.95, after upgrade it only detects 2048x1152@60. Display port works OK. 2 monitors, same behavior. Revert to 580.95 fixed it. Monitor: PL3270Q, GPU: RTX 3060 Laptop
In release notes for 580.105 they introduced some bugfixes for HDMI resolution - it seems they added some new ones.
Great, thanks for the info! Apologies for duplicating the post. I looked for a thread documenting it but did not find the reply in the feedback thread.
Any chance this issue could have started before 580.105.08? Iāve had a similar (maybe itās the same) problem with every version of 580. In short, my external HDMI monitor is only able to do 1366x768 when it should be able to do 1920x1080@75. I posted about it here but have never received any response from anyone at NVIDIA.
That post was before 580.105.08 was released, but I can confirm itās still the same problem now. Iād be happy to generate additional logs or test any distro/driver version Iām able to.
@forbyta we have identified the regression that has wide impact to have been caused by a change only introduced in 580.105.08. There could be another issue impacting you. Let me take a look through your original post.
A solution for everyone, or just for those with newer GPUs which support the open drivers?
I see thereās a patch out for those, but I have a GTX 1080.
