Multi Channel Display [2,3,4] vs. NUC Notes

2016/02/27

Hardware

Intel NUC 6i5SYK (i5-6260U 1.8GHz, Mini DisplayPort 1.2, HDMI 1.4b, Iris 540)
Samsung 850 EVO 250 GB M.2 SSD
Kingston HyperX 16GB DDR4

 

Display
1 x Sony VPL-FHZ55 projector
1 x 1920 x 1080 display AOC
2 x 1920 x 1080 Samsung TV
2 x 1920 x 1600 Dell 2407 LCD
Club 3d Multi Stream Transport Hub
1 x HDMI M to DVI M cable
1 x HDMI M to HDMI M 3M
1 x DisplayPort M to Mini DisplayPort M
2 x DisplayPort M to HDMI M

 

Software

Fedora 23 as per previous notes.

Then, either update xorg-x11-drv-intel to 2016 drop by cannibalizing F24 development, or install via Intel Graphics Installer for Linux. See Intel Open Source site, ie 01.org.

Some useful background information from the Fedora Project on How to Debug Xorg Problems.

To probe the current graphics situation, run

grep " (--) " /var/log/Xorg.0.log

Other useful queries

grep " (II) " /var/log/Xorg.0.log;
grep " (II) " /var/log/Xorg.0.log | grep connected;
grep " (II) " /var/log/Xorg.0.log | grep drm;
grep " (II) " /var/log/Xorg.0.log | grep EDID;

 

On the NUC, the above gives the following output

[bkoz@otis log]$ grep " (II) " /var/log/Xorg.0.log | grep EDID;
[    17.236] (II) VESA(0): EDID Version: 1.3
[    17.237] (II) VESA(0): EDID (in hex):
[    17.237] (II) VESA(0): EDID vendor "AOC", prod id 9063
[    17.237] (II) VESA(0): Using EDID range info for horizontal sync
[    17.237] (II) VESA(0): Using EDID range info for vertical refresh

[bkoz@otis log]$ grep " (--) " /var/log/Xorg.0.log
[    17.157] Markers: (--) probed, (**) from config file, (==) default setting,

[    17.284] (--) VESA(0): Virtual size is 1920x1080 (pitch 1920)

 

Test matrix

SW Connection-Display-Driver Status
F23 1 x HDMI 1080p vesa OK
F23 1 x Mini DisplayPort 1080p vesa visible but clipped

 

Future Attempts

Hand-rolled xorg.conf files. See How to create xorg.conf.

Windows 10 is supported.

Can MacOS + mini drive 4 x displays?
