Mint 18.2 on Compulab Airtop PC - no hi-res output on HDMI port of Intel integrated graphics

Post by phz » Tue Dec 12, 2017 9:11 am

Hello all,

I have a Compulab Airtop PC (http://airtop-pc.com/) here, and I can't get any monitor on the HDMI interfaces to work with a higher resolution than FullHD (1920x1080). Looking at the manufacturer's website, it's an Intel Iris Pro 6200 graphics card which should support 3x 4K: http://airtop-pc.com/airtop/specificati ... 775-W-FM4U

The onbord grahics card has three interfaces (1x DP, 2x HDMI). On the DP interface, I have connected a BENQ display running at 2560x1440 pixels. When I connect a second screen on one of the HDMI ports, it either doesn't come up at all or it's running at 1920x1080 pixels, but arandr won't let me select a higher resolution.

I've tried many different monitors and cables. I've also tested the monitors on other PCs, to make sure they work fine with higher resolutions.

This is what "inxi -Fxz" says:

In drivers section are there additional drivers present for the displays? If so try using them reboot and test.

Or update kernel to highest version for 4.10 series. Reboot and test
If I have helped you solve a problem, please add [SOLVED] to your first post title, it helps other users looking for help, and keeps the forum clean.
I am using Mint 19 Cinnamon 64 bit with AMD A8/7410 processor . Memory 8GB

Hi, thanks for your reply. There are no additional drivers in the driver manager. In the meantime, I run kernel 4.13.0-26-generic.
