Twin HDMI

Hello,

I have an Intel NUC7PJYH running CentOS 6.8. This is a NUC with standard USB, 1GbE and 2*HDMI.

Installation was no problem providing acpi=off.

The problem is that by default the two displays are mirrored and I can’t seem to separate them.

I can only see one HDMI port from CentOS.

I need to see both HDMI ports discreetly.

Can you please help.

  • It should be adjustable in the CentOS6 equivalent of System Preferences->Hardware->Displays

  • FWIW, that has a Pentium Silver J2005, which has Intel® UHD Graphics 605

    thats fairly new stuff, and CentOS 6 is pretty old now.

  • Hi John, why not try something newer than CentOS 6.8 ?
    Maybe not the latest 8.1 but 7.7 is quite recent and stable.

    Your (integrated) video card is :
    Intel® HD Graphics 605 (NUC7PJYH)

    Intel NUC7PJYH seems to be able to pilot Dual 4K display :

    ” …The NUC7PJYH kit also comes with dual Ultra HD 4K display support via two full-sized HDMI* ports, consumer infrared, and a TOSLINK audio jack, they’ve got everything they need to stream media, play, or finish that last-minute presentation. And with 3.2x better graphics,3
    2 you can create robust entry-level digital signage at entry-level prices for your SMB customers.”

    First step is to post here the output of “hwinfo –gfxcard”

    Some useful info is published here (sorry not CentOS related)

  • Hello,

    The resolution to the dual HDMI problem was to upgrade to CentOS 7.5.

    All CentOS versions from 7.5 to 8.1 work with no problems.

    Thank you for your help.
