CentOS - Jan 2020 - 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)
