Problem with 3440x1440px on Intel UHD 630 and Windows 10

[PiotrB]

Hello,

I have a Lenovo IdeaCentre5-14 computer with an Intel UHD 630 graphics card and a Philips 34" 34M1C5500VA monitor. When it is connected via HDMI, the maximum resolution I can select is 2560x1080px, instead of the monitor's default resolution of 3440x1440px. With the previous iiyama B2791QSU monitor, the computer supported the resolution of 2560x1440px without any problems. Has anyone had a similar problem? Thank you for your help

iiyama ProLite B2791QSU
2560 x 1440 @ 75 Hz
1 x HDMI 1.4

Philips Evnia 5000 Series 34M1C5500VA
3440 x 1440 @ 100 Hz
2 x HDMI 2.0

If I understand correctly, you have this computer:

Lenovo IdeaCentre 5 14IOB6 - Product Specifications Reference

It only offers HDMI 2.0 as a digital output, no DisplayPort. Is that correct?

According to Philips, 3440 x 1440 @ 165 Hz is only possible via DisplayPort. HDMI is limited to 100 Hz. However, that still fits within the bandwidth of HDMI 2.0.

To see what the Philips monitor is sending to the graphics driver, please create a Report for Intel Graphics Drivers and attach the output file here.

I am attaching a report from the Intel.

I think this computer has HDMI version 1.4 - below picture form the manual.

According to the diagnostic data, the monitor does not support 2560 x 1440. The highest supported resolution that is within the bandwidth of HDMI 1.4 is 2560 x 1080. The native resolution of the monitor would be 3440 x 1440. According to the diagnostic data, 319.75 MHz pixel clock would be necessary for 60 Hz. The Intel UHD630 can unfortunately only work with a maximum of 300 MHz pixel clock via the native HDMI 1.4 interface.
