CentOS 6.9 not recognizing HDMI1 output

Postby eas3964 » 2017/04/28 01:18:55

Hello, all...

I have an Intel G43/G45 Integrated Chipset on my motherboard and it has both a VGA and an HDMI output. However, only the VGA output is recognized. When I run xrandr, it says HDMI1 is disconnected, even though the monitor is plugged in and powered on. I see a lot of NVIDIA posts, but I have an Intel graphics card and need a post specific to this. This worked in CentOS 6.3 but when I upgraded to 6.9 the HDMI output became nonfunctional. Any help is greatly appreciated.

Thanks!

Attached are screenshots of my xrandr (I'm not sure how to pose code).

I've seen some Dell monitors where you manually have to select the input source.

Code: Select all

[root@awips awips]# xrandr --output HDMI1 --mode "1920x1080_60.00" --right-of VGA1
xrandr: Configure crtc 1 failed


I had already run xrandr --newmode and xrandr --addmode. However when I run xrandr --output I get

Code: Select all

xrandr: Configure crtc 1 failed


How can I make this work? It'd be nice to have both monitors working. They both worked when I was running CentOS 6.3, but after the upgrade to 6.9 the HDMI stopped working.

Thanks!
