exists on drm-intel-testing-2015-03-27 exists on drm-intel-testing-2015-04-10 Exists on drm-intel-testing-2015-04-23 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? Timeout - marking as resolved+worksforme. Jeff, please reopen if this is still problem on the latest kernel (preferable from drm-tip). |

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
