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.
