Hello, I have been testing my 2k display that just came in and it looks like the display works over HDMI with the PC at 2560x1440 and 1080p however upon connecting the display to the firefly the screen is dark. It shows an active handshake with the Firefly but nothing is displayed.

Anything you can do to help?

We are running android 7.1.1 with firmware 4.5? would have to check on the additional details. ADB reports resolution as unsupported for some reason.

http://wiki.t-firefly.com/index. ... 99/Starter_guide/en Also your Starter Wiki points out that you can set the resolution to Auto in the settings menu, however I do not see this option on our 7.1.1 system. Is there a fix for this or is there a manual command we can run to force the device into 2560x1400 resolution?

Tried that method through ADB the density of the screen was off and still no display on the topfoison screen. Do you think setting display output to DVI and or adding non EDID options could sort the issue? Is there a boot.ini or boot.scr file that cane be edited?

did you have another 2K monitor?

Yes will test with another 2K dispplay tonight and let you know.

Tested with Dell UD2717D 2560x1440 IPS monitor and was able to get Firefly to display. So there is something off EDID or HDCP or something with the TOPFOISON. Maybe it is causing the board to fallback to 1080p which that display does not support. Any logs I can send your way?

adb log & kernel log.
