Troubleshooting • Re: Unable to set resolution to 1080p, stuck at 1024x768

Try the recent method with a D,

Code:

video=HDMI-A-1:1920x1080M@60D
as discussed here viewtopic.php?t=390321
OK, so that looks like it works. My issue wasn't a blank display like in the thread you linked to, but that solution appears to solve my problem. Maybe it will work for the OP of this thread too.

Thank you.


EDIT: Addendum:
So, the screen is behaving correctly. It is displaying 1920x1080 like it should, however..

Code:

zero1:~ $ kmsprint -mConnector 0 (33) HDMI-A-1 (connected)   0 1024x768@60.00    65.000 1024/24/136/160/-  768/3/6/29/-       60 (60.00) D        1 800x600@60.32     40.000 800/40/128/88/+    600/1/4/23/+       60 (60.32) D        2 800x600@56.25     36.000 800/24/72/128/+    600/1/2/22/+       56 (56.25) D        3 848x480@60.00     33.750 848/16/112/112/+   480/6/8/23/+       60 (60.00) D        4 640x480@59.94     25.175 640/16/96/48/-     480/10/2/33/-      60 (59.94) D
kms still thinks I can only go up to 1024x768. Here's what I get within a few moments of booting up and logging in:

At some point, usually around 30 seconds but sometimes as long as 5 minutes, it will revert to the first list.
