Hello! I’ve stumbled upon problem with HDMI output on BPI-M2U. The problem is with corruption or shift of the first 4 lines in 1080p mode in both console and X-window. This problem persists with both 1080p50 and 1080p60 modes and with different linux distributions (namely 2016-11-29-ubuntu-16.04.1-mate-desktop-preview3-bpi-m2u-sd-emmc.img.zip and 2017-01-20-debian-8-jessie-lite-beta3-bpi-m2u.img.zip) . I’ve checked my m2u with more then 10 different cables and monitors/tv’s so the problem is not with cables or monitors. To illustrate the problem I took two photos:
- Corruption and occasional flickering on some monitors (the small black box 2x4 pixels at the left upper corner):
- Shift of first 4 lines with occasional flickering:
On some monitors the image is unstable and flickers once/twice per second. Does anybody have a solution to this problem?
