Description Jeff Zheng 2015-03-17 07:54:08 UTC 
Created attachment 114377 [details]
dmesg with "testdisplay -d 16"

==System Environment==
--------------------------
HDMI monitor: ASUS VS239HR
DP monitor: ASUS PA238Q
BIOS: V59 
Regression: Not sure. I tried drm-intel-testing-2015-02-14 and drm-intel-testing-2015-01-30 but the status is bad so cannot try. The processor and BIOS has upgraded this time.

Non-working platforms: BSW

==kernel==
--------------------------
-testing: drm-intel-testing-2015-03-13 (fails)

==Bug detailed description==
-----------------------------
"testdisplay -d 16" does not show rendered picture for all resolutions in HDMI monitor 

After this, "testdisplay -o 47, -d 16" shows normal  (here 47 is the id of HDMI monitor).

"testdisplay -a" and "testdisplay -d 32" also fail.

==Reproduce steps==
---------------------------- 
1. Connect HDMI and DP monitors and boot
2. testdisplay -d 16

tested on drm-intel-testing-2015-05-22 + V69 BIOS, this issue still exists.
DP monitor: Dell U2311Hb
HDMI monitor: Samsung LS24C570

When I first ran "testdisplay -a", it looks fine, but then I ran "tstdisplay -d 16", this issue appeared again.

Jeff, is it still occurring?
Comment 6 Jari Tahvanainen 2017-03-27 14:47:23 UTC 
Timeout - marking as resolved+worksforme. Jeff, please reopen if this is still problem on the latest kernel (preferable from drm-tip).
