Intel HD Graphics 620 / 630 cannot identify 3840 * 1080 monitor in Win10

[JHuan95]

Dear Sirs,

I have a monitor with single HDMI input, which resolution is 3840 * 1080.

However my Gigabyte mini PC cannot identify the monitor resolution in Windows10.

It always shows 1920 * 1080.

My mini PC model is BKi5A-7200, CPU is Kaby Lake which has Intel HD Graphics 620.

I changed another PC with Intel HD Graphics 630.

However the situation is still the same...

Windows 10 cannot correct identify the monitor resolution but always show 1920 * 1080.

I have already updated HD Graphics 620 and 630 driver to latest one but the situation is still the same.

The resolution in windows 10 is still 1920 * 1080.

This monitor works fine with NVIDIA graphic card GTX 1070 with HDMI port,

So I don't think it is monitor's issue..

Would you like to help suggest?

I have posted the support log of HD Graphics 620, you can find EDID inside.

There are two EDID within the log, the 2nd one is 3840 * 1080.

At first try different cables.

Get them from dealers who promise to take them back in case of trouble.

Make sure they are certified for 18 GBps (GigaBaud)
