A750 Secondary Monitor won't display 4k w/ latest driver after reboot

[pizzapie]

Hello,

I have an Intel A750 which hadn't had any issues until the latest drivers (31.0.101.5522).

It seems to happen after a random amount of time after driver installation (replicated multiple times with DDU + reinstall), which after reboot my secondary display will only show as 1080p even though it display 4k without issue beforehand. When going into display options, it won't allow you to force 4k either.

It's worth nothing the monitor isn't the issue as I've swapped ports etc, it's just whatever isn't the primary display gets affected it seems.

Hello Pizzapie,

Thank you for posting in our communities.

May we know if you have tried to roll back your graphics driver? If yes, does the issue not occur with the previous driver? because if yes, this might be a driver regression.

Furthermore, you may also check out this link for a possible solution to our issue:

• Unable to Select the Native Resolution and Other Supported Refresh Rate of an External Display Connected to Intel® Graphics.

We look forward to your response!

Hi there,

Apologies about the delayed reply, the suggested solution regarding rolling back the driver seems to have worked.

Hopefully it can be resolved in a future driver update by you guys.

Many thanks,

Hello Pizzapie,

Thank you so much for the response.

Let's stick with the prior or earlier driver for the time being, and when there is a new release driver, I will let you know so we can try it.

By the way, you're very welcome.
