Lenovo T460 Intel(R) Graphic 520 3440x1440 refresh limited to 50Hz

[manster6475]

Hello, 

I have a Lenovo T460 with Intel(R) Graphic 520 and Lenovo screen G34w-10 . I manage to get  3440x1440 resolution but I do not seem to get refresh above 50Hz what is the reason? I use a 2.1 HDMI. 

Below is the report.

Thanks in advance.
Regards

- Is this the first time that you try to set up that resolution (3440x1440) at that refresh rate (50Hz) or were you able to use it before? If yes, was there any recent change related to the point when the issue started?

-  Are you using a straight-through connection (e.g. HDMI-to-HDMI, DVI-to-DVI) with a single cable? Or are you using any type of video adapters, converters, or dockings? Please provide details.

-Have you check with the display’s manufacturer to see if you have the latest patch update, driver, and firmware for that monitor?

I look forward to hearing from you.
