UHD 630, 5120x1440 not listed as supported mode via USB-C

[zachpn]

Hi.
I am trying to get my new Monitor running properly on my laptop.
Monitor Samsung G9 Neo LS49AG95 (5120x1440 native)

PC: Dell latitude 5591 with intel  i7- 8850H; UHD 630 and Nvidia MX130
Latest UHD630 driver is installed: 31.0.101.2111

Cable used: 4k HDMI to USB-C Cable

Max supported resolution: 3840 x 1080 (60p Hz, 4K)

I tried the Dell 5k enable .reg patch, reinstalled monitor drivers, updated UHD Drivers, tried to add the resolution with intel gfx control software, and tried to add the resolution with GRU. Nothing worked.

Report is attached.
Any help is appreciated.

Hello zachpn,

Thank you for posting on the Intel® communities.

Please provide the following information:

• Have you tried a straight connection? We do not recommend the use of video adapters/dongles/docking station as it can cause video issues.
• Have you tried the latest OEM driver 30.0.101.1338 (https://www.dell.com/support/home/en-us/product-support/product/latitude-15-5591-laptop/drivers)?
• Were you able to get that resolution in the past? It is possible that resolution it is not supported due to graphics limitations.

According to the manual provided by Dell, the maximum resolution for HDMI 2.0 is

4096x2160 at 60 Hz, page 14 (https://dl.dell.com/topicspdf/latitude-15-5591-laptop_specifications2_en-us.pdf). As well, please check the processor graphics specifications here https://ark.intel.com/content/www/us/en/ark/products/134899/intel-core-i78850h-processor-9m-cache-up-to-4-30-ghz.html

Hello,

- As the Laptop does not have a DP connection but only HDMI 1.2, and because the DP port on my Monitor is already occupied, the HDMI to USB-C cable is as straight as I can go.
- I did not use any Beta drivers, no

- On this Laptop? No. Its a new Monitor.

The issue was the Cable I used. I could not deliver the required bandwith. When I added 5120x1440@30Hz with GRU, the option was also displayed in the display settings.
Bought a new 8K@30Hz HDMI cable and now 5120x1440 @60Hz is working.
