External monitor fails when maxing resolution with new settings dialog, iff the dialog is on that monitor |
||||||||||||||||||||
Issue descriptionChrome Version: 60.0.3112.41 (Official Build) beta (32-bit) OS: Chrome OS 9592.29.0 (Official Build) beta-channel kevin What steps will reproduce the problem? (1) Hook up a ZR30w to a Kevin in extended display mode at 1280x800 (2) Open chrome://settings/display. Make sure the window is on the external monitor. (3) Change external monitor's resolution to 2560x1600 What is the expected result? Monitor switches to new resolution What happens instead? The monitor goes black, even though the backlight flickers back on. If I try to switch the resolution back I can see the backlight flicker (so it's definitely receiving something), but the screen stays black. I have to unplug/replug the monitor to get it working again. I don't know if this is a Kevin-specific platform issue or a general problem with the new settings dialog. I presume it's at least partially the latter because it seems to work just fine if I have the settings dialog window on my internal display instead -- where the window is affects whether the bug happens. This definitely didn't yet happen a few revisions ago (with the old settings dialog). Feedback report: https://feedback.corp.google.com/product/208/neutron?lView=rd&lReport=67748204590

@robertrtung my display is not working :-/ Could you look into this as part of the other monitor improvements you've been doing?

Not sure if this is the same bug but I found the following: I tried to reproduce the bug with my HPZ27n monitor and a Kevin, as well as with the same external display and a Caroline. With the Caroline, I didn't have any issues regardless of how I changed the display resolution and on which screen I put the settings page. However, on the Kevin, if I started both the external display and internal displays at the default, optimal resolution, and then change the HPZ27n monitor to 1440x900, the display flickers rapidly. Still, this seems to happen even if the settings page is on the Kevin's internal display, and isn't exactly what you described, so perhaps it is specific to the ZR30w monitor you are using, and I am unable to reproduce this. Perhaps oshima@ may know why the result could be different on different monitors, or perhaps alberto@ would have insight on the Kevin side.

Doesn't quite sound like my issue. FWIW I can still reproduce it just as described above on 60.0.3112.72. I even recently changed to a different display adapter (HDMI->DVI instead of DP), so it doesn't seem to have anything to do itself. Still might be the monitor, of course. I'm happy to demo it to you if you want.

@ovanieva, do you want to look at this as part of display settings?

FWIW the issue is still reproducible exactly as described on my system. Let me know if you want a demonstration.

Tried to repro on a kevin + HP Z27n with max resolution 2560x1440, but couldn't see the issue. Malay, can you please try to repro on your end?
