Hello, thanks for taking the time to read my post and also thanks for this amazing space where you share so much knowledge about displays.
I have a Xiaomi 34" ultrawide monitor, in CRU it appears as XMI3446, the SKU is BHR5132US, this is the product:
https://www.mi.com/uk/monitor34/
This is using Windows 10: I have connected it with an HDMI cable to a laptop (ASUS GL753VD-DS71) that has an Nvidia/Intel display adapter (GTX 1050 4GB and Intel HD graphics 630 - 7700HQ CPU).
A few weeks ago I was able to set the resolution to 3440x1440 and switch the refresh rate from 50 Hz to 100 Hz, then I got another laptop with Windows 11 and tried it with the monitor, unplugged the Asus laptop and worked with the new one for some days.
2 or 3 days ago I reconnected the Asus laptop to the monitor, and this time I can't switch the refresh rate to 100 Hz, the option disappeared and I can only select 49.998 Hz (not even 50, weird) as refresh rate.
I tried adding 100 Hz refresh rate to the 3440x1440 resolution with the latest version of CRU under "Detailed resolutions" (closed and ran the restart.exe file), but when I go to the "advanced display settings" section of windows 10, it doesn't show up, and it doesn't show up on the "list all modes" of the display adapter properties either.
Same thing happened with the other laptop, it has an intel 1215u (Walmart brand, Onn, does not appear anywhere) and Windows 11, I could plug it to an USB-C to HDMI adapter and switch from 50 Hz to 100 Hz, but now I can't do it anymore, I just get the 49.998 Hz weird option.
I have also tried using the same HDMI cable (the one from the other laptop) with the 1215u laptop but it didn't even accept the 3440x1440 resolution from the start, it only displays a stretched resolution of 1920x1080; can someone help me determine what should I do to get the 1215u laptop to display the 3440x1440 21:9 resolution through the HDMI port?
I'd also appreciate help to recover the 100 Hz refresh rate for the 3440x1440 resolution for both laptops or to at least add 75 or 60 Hz as options for that resolution. Thanks again.
*I've tried 5 different HDMI cables and got the same result (tried 2 more HDMI cables a few minutes ago).
