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?
Same here on every image tested 11-22-16 and newer. Sooo, BananaPi support people, is this
a hardware problem? A fex problem? Something you’re working on? Something you’re gonna fix?
This is unusable at 1080P. This never should have shipped. Is there a person there who is
responsible there (foxxconn/bpi/sinovoip)? Anyone working to fix things or communicate with
users or are you just content to sit around and collect your next paycheck.
Your organization and accountability suck.
Here’s hoping a kick in the butt will get you to do something…
I am running M2-U with 1080P on my monitor without the corruption or flickering you are experiencing. Still have the 2x2 (2x4?) black pixel at the upper left corner though.
I have not done any research on this 2x2 pixel hole or tried to fix this.
I was using a 2010ish monitor before. Just upgraded to a new acer today and now only get the black hole in the upper left as well. Seems 1080p isn’t big in China or their engineers would have caught this.
