5k 5120 * 2160 resolution on Intel UHD Graphics not working for me

[wolfhongkong]

Dear Community,

I recently switched from a MacBook Pro (2018) to a brand new Lenovo T15.

With the Mac I was using an LG 34WK95U-W 5k screen with a resolution of 5120 * 2160.

It seems that the maximum resolution I can get with the Lenovo (running Windows 10) is 

3840*2160.

I have installed the driver for the screen, I have installed the latest Intel UHD driver that Lenovo offers, but no luck. 

I guess my first question is: Is the Lenovo even able to power a 5k display. It has the following processor: 

• Intel(R) Core(TM) i7-10610U CPU @ 1.80GHz 2.30 GHz
• The Intel UHD driver is from 2022-08-24 and has the version number 31-0.101.2114
• Latest LG 5k driver for Windows 10 is installed (LG HDR 5K (Display Port)

I connect the LG screen via display port (1.4 (I also tried 1.2 and 1.1)) to a Dell docking station and then via USB-C/Thunderbolt to the Lenovo. (When I connect the docking station to my Mac it works immediately. So I know that the display port and the docking station itself can handle 5k)

BTW, if I try to connect directly via Thunderbolt to the Lenovo, the whole display stays black.

Thanks for your suggestions / help.

Your processor's graphics output capabilities are as follows: 

• Max Resolution (HDMI)      4096x2304@24Hz
• Max Resolution (DP)           4096x2304@60Hz

As you can see, there is no support for 5K monitors (certainly not at 60Hz). If you can connect the monitor via DisplayPort or Thunderbolt Port, you could try creating a custom configuration that is set for 5120x2160@30Hz.

I don't recommend attempting this using the dock. I would recommend trying it with a USB-C-to-HDMI 2.0 adapter. 

Hope this helps,
