4k monitor showing 1920 X 1080

[Krt5]

I am running a windows 10 Hp Spectre from 2017. It has Intel HD Graphics 620. I connected the laptop to the monitor via the Hp type C to HDMI adaptor. The monitor is a 4k monitor.

When i go to display settings on my laptop for the 4k  monitor, it says desktop resolution is 1920 and active signal resolution is 3840. I have manually updated graphics driver to version 31.0.101.2115. How can i fix this issue. I have already ruled out the HDMI and the monitor by having the monitor display 4k using another laptop and same type c to hdmi cord.

Hi @Krt5,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If your 4k monitor is displaying at 1920 x 1080 resolution instead of 3840 x 2160 (4k resolution), there are a few steps you can take to troubleshoot and potentially fix this issue.

Check Display Settings:

• Right-click on the desktop and select Display settings.
• Under Display, make sure your 4k monitor is selected.
• Scroll down to the Scale and layout section and ensure the scaling is set to 100% for the monitor.

Update Graphics Driver:

• You mentioned you've already updated the graphics driver manually, which is good. Ensure you've installed the latest driver from the Intel website that supports your Intel HD Graphics 620.

Check HDMI Adapter Compatibility:

• Sometimes, HDMI adapters or cables might not support full 4k resolution at higher refresh rates. Ensure your HDMI adapter is capable of supporting 4k resolution at 60Hz.

Adjust Resolution Manually:

• If the correct resolution isn't automatically detected, you can try setting the resolution manually:
  • Go to Display settings.
  • Scroll down and click on Advanced display settings.
  • Choose the monitor in question and then select Display adapter properties for Display X (where X is your 4k monitor).
  • In the Adapter tab, click List All Modes, and select the appropriate 4k resolution (3840 x 2160).

Check Cable and Connections:

• Ensure the HDMI cable you're using is HDMI 2.0 or higher, as older HDMI versions may not support 4k resolution at higher refresh rates.

Restart Your Computer:

• Sometimes, a simple restart can resolve display resolution issues, especially after driver updates or settings changes.

Update Windows:

• Make sure your Windows 10 operating system is up to date, as updates can sometimes include fixes for display issues.

Check BIOS Settings (Advanced):

• If you're comfortable accessing your BIOS settings, ensure that there are no specific settings related to graphics or display output that could be affecting resolution.

I hope this helps.

Take care and have a good day.
